Passat B6 EML and flashing glow plug light

[MarkC89]

Hello All,

This is my first post and I must apologise for the lack of introduction. However at the moment I'm having a nightmare of a time with our Passat and by the looks of reading through the forum, Passat problems aren't what you'd call a regular occurrence.

I will try to cut a long story short but here goes. Oh, you'll probably want me to upload and error code log but I can only do this tomorrow when I'm at my computer.

Anyhow, sometime ago I was driving a long a poof, the engine oil is all over the road along with chunks of metal. What happened is the rev limiter shot up to the top and the crankshaft came off, hit the engine and produced 2 holes into which you could put your hand. All this was typical signs of a diesel run away. However, I was so surprised at how quickly it wrote of the engine. There was no time to stall it or do anything at all.

Next stage is of course the car goes to the mechanic and he delivers the bad news. After this we agree to get a new engine. The engine we bought was bare, the block, the head and that was pretty much it. All auxiliary parts, injectors, glow plugs etc. from our car. Before we go into this I'm not entirely sure if this is normal practice to sell an engine like this but here in Poland, where I'm currently living, it is.

The turbo was sent off for repair but the renovation company said the turbo was in very good condition and to renovate would be a waste of money. Therefore, they cleaned it for us and returned it to the garage. I trust what they say is true as they've renovated a turbo from another car we had and it's a professional company with a good reputation here. They could have ripped us off and charged us but they didn't.

Mechanic puts everything back together, installs new cam belt, water pump, oil pump, head gasket etc. There you go, all is well again and the car is running superbly if not better than before the engine swap.

Driving the car for about a week and the engine light comes on. I have a VAG-COM so plugged that in. Comes up with several codes, intermittent this, intermittent that, electrical this, electrical that, along with injector 2 and glow plug 3 and 4. Mechanic says clear the codes and if it comes on again come back, of course they do and of course we do. He says cheapest option is to replace the glow plugs, if the light comes back on we will investigate further, he then replaces all glow plugs for brand new ones. All is well again, or so we think. Later on I'm just pulling out of the petrol garage, drive about a mile up the road then have lack of power, car pulls back, exactly like it did the first time, then shoots off up to the top of the rev gauge again. However, this time I'm quick on my toes and stall it immediately, saving the engine. At this point I'm confused. Not a scooby doo as to how considering we have a new engine and all parts have been checked and or replaced.

Mechanic comes and collects the car, again. Takes it apart and says there is 5 liters of diesel in the oil and therefor immediately suspects the injectors. We look into all options and find a company to renovate the injectors, spoke to the guy from the company several times who assured us yes we will fix them if there is a problem and if not we'll use new parts we have here (again a professional company with a good record). Guy sends them back saying there is nothing wrong with your injectors we've tested them and all is fine. Charged us for cleaning them and returns then to us. Mechanic puts them back in, starts it up and revs to the top again and tells us there is diesel in the oil again. By this point mechanic is ****** off too. We leave it with him and he says let me consider all options. He gets somebody in to help and recommend and he decides the replaced the fuel pump. The smaller fuel pump so I'm told, there a 2 pumps.

Car starts fine and is back up and running again. A week of driving and 1000 kilometers later and we are still going. However the EML light has come on again kicking out many codes of an electrical nature, steering lock this, parking brake this, AVHC that, electrical that, including all 4 spark plugs but no injectors issues. I've reset it all once but it came back again. Left it to be honest with you as I'm ****** off with it, the car was driving fine and I'm convinced this is some electrical problem that is unrelated or so I hope. That and plus the fact I have to go to work and have no time to take it back to the mechanic until the weekend. Today, again, more problems now the glow plug light is flashing and for sometime the handbrake error light was on (although that went off) now we are at the stage were we have the EML and flashing glow plug light on, me scared to drive it in case something happens again and I've no idea what to do.

Basically what else could this be?
A. The runaway wasn't really a runaway and something else caused this to happen? Another part which was not replaced.
B. This is an unrelated problem caused by the engine exploding the first time around?

What are all of the problems that could cause the engine to become a runaway, the engine itself excluded as that was replaced?

What are all of the possibilities of the engine revving it's guts out by itself and for example being another part/wiring or something?

As it stands I'm checking the oil every day and the level has not risen at all so no diesel seems to be leaking in the engine but I've now no clue what to do.

Please throw some suggestions my way

Kind Regards all

Mark

What you had is called "diesel runaway", bloody frightening when it happens! Do the code read and post.

Good Morning,

Reading through what I wrote last night, it seems a little all over the place. Apologies but I was writing late and from my phone.

I will try and add a few more specific details later when I'm at home and can upload fault codes received with my VAG-COM.

On another note, driving to work this morning and the glow plug light was on and off throughout my whole journey. 5 mins on 5 mins off, 5 mins on 10 mins off and so on. Leading me to believe there is some kind of underlying electrical problem.

When it comes to the runaway diesel, could the fuel pump really have been the cause? This is the last part the mechanic replaced and since this, touch wood, there has been no problem in this area. I've since done 1000KM and the mechanic explained that after 2000 KM if there are no problems in this area then the fuel pump replacement has fixed the problem and it won't happen again. He advised me to check the oil level every morning before going to work which I have been doing and it has remained the same.

Thanks again

I'll update later this evening, but please in the meantime feel free to throw some ideas this way.

Regards

Mark

Some of the faults listed in your Autoscan are historic. You should go into each module and clear the fault code/s
Then in a week see which, if any, return

I can't see the header information of your Autoscan so don't know whether the readings are accurate from the
version of VCDS you're using

[Gazwould]

Some correct and incorrect statements in that first post .

The words Passat and nightmare in the same sentence are correct , Mk6 the B6 , very much so for the diesels and especially the 2.0 tdi BKP .

Then when you do sort it out, you have the multiple fault engineering monstrosity oil pump drive to future proof or it might be replacement engine number 2 .

This is how they do it in Poland .

Some of the faults listed in your Autoscan are historic. You should go into each module and clear the fault code/s
Then in a week see which, if any, return

I can't see the header information of your Autoscan so don't know whether the readings are accurate from the
version of VCDS you're using

The fault codes are all new, I've reset all DTC's several times and they all return.

And version of VCDS I think is 12.85? Not in front of my PC right now. However, for sure is 12.something

Some correct and incorrect statements in that first post .

The words Passat and nightmare in the same sentence are correct , Mk6 the B6 , very much so for the diesels and especially the 2.0 tdi BKP .

Incorrect is " Passat problems aren't what you'd call a regular occurrence."

If only I'd known it before.

Excuse my ignorance, but oil pump drive I'm not too sure about this. The mechanic explained he changed the oil pump for a different one (a different generation I believe) he explained the one we had was known for being unreliable, and yes, unfortunately we also have the BKP engine. The mechanic also explained that this engine was also known for several faults too.

I'm a confidant DIY enthusiast who can carry out work if I know the problem. So sometimes I'm not entirely sure about the specific details. Also, with newer cars these days and the electronics etc. it's a little more difficult than your mechanical engine. My last real big mechanical job was replacing the engine in a ford escort. So I'm not completely stupid, I just need a lot of advice when it comes to diagnostics.

To summarise the current situation with the Passat, oil pump changed, injectors checked and cleaned, turbo checked and cleaned, new cam belt, new water pump, new glow plugs, new fuel pump. Therefore I don't really know what is left than some perhaps, catastrophic? (I say this as everything seems to be throwing up error codes) problem.

The car drives normally, all areas which come up with an error code don't seem (I'll use this word lightly as we all know what to assume is) to be malfunctioning.

Oh, the only one thing I noticed. The engine quickly shuddering when being turned off. I believe there is a valve or something to prevent this? Can't remember the name of it, I often read that people talk about removing it. Anyhow, it never used to this this before and it doesn't do it all of the time.

I think I'll update my version of VCDS also and rescan.

I'm still driving the car but have no choice, I need to get about and go to work, so I hope by driving it won't cause any further problems.

Anti shudder valve .

The oil pump problem has been well reported all over the world since 2008 and denied by VAG and only 1 recall in Korea .

The oil pump change could mean anything , from the oil pump cassette , chain driven to gear oem conversion , chain driven to gear remanufactured balancer shaft conversion , chain tensioner replaced , and remanufactured modified balancer shaft and longer harder 100mm hex key .

You need to find out exactly what has been done .

[RichardSEL]

VCDS is up to 16. something or other now (different for cloud app). Perhaps worth connecting your laptop to t'net and allowing update?
Should be automatic from Ross-Tech's server

Sorry, don't speak Derv -- except from what I've learned by going out to do scans, and what I've learned in here --

The reason you were unable to stop your engine destroying itself when it ran away is the faulty V157, this shuts the air intake and kills the engine when you turn off the ignition so the engine has been repaired and sent back out without the cause of failure being rectified. It needs a new manifold flap ASAP!

The thing is, the engine destroyed itself immediately before I could even do anything the first time. It revved up very quickly I dropped the clutch to change gear put the brakes on and then went for the key but as I was pulling it out the engine ripped itself apart. The second time I don't even know what worked pulling the key out or stalling it. The second time I dropped the clutch, put it into 6th but the brakes on and pulled the key out then it stopped. Don't ask me why I did both but I wanted to have double the chance of saving the engine. I know pulling the key should work but read that many times it doesn't so I went for the stall option too, either way it saved the engine. The problem is why it became a runaway. If the valve is faulty, then of course that may prevent me from stopping a run away, but it's not the cause of the runaway surely?

On another note I'm running 12.12.3 VAG-COM. It won't however let me update. Any ideas on these faults being thrown up. I know the dates etc are wrong and I've no idea why but these are fresh faults, I've reset them several times and they come back.

Sounds like the beta version that escaped to t'net a few years back. I don't know what dongle you've got to go with, but you can download the latest full VCDS version from Ross-Tech's web site. It won't install if you have a pirate cloned dongle though. Where did you buy, how much?

[MarkC89]

I bought mine from amazon it was about £50 if I remember correctly. It came with an installation CD. I previously had a crappy blue dongle from eBay with the lite version of VAG-COM, but it could never read the codes so I bought the one from amazon. Which seems to work fine so I never questioned it.

Amazon have been warned. But it's such a big organisation, and the US inventor Uwe Ross of Ross-Tech in the US has complained but they get ignored. I bought from them when there was no UK sales agent. And had to pay all those extra charges -- UPS, etc. etc. I was in dispute over warranty claim with my local VW dealership (we're not allowed to say stea... erm y'know, that word in here) that it immediately saved me its cost and then some.

Been saving on mine and other's B6s and others of '05 to '08MY since!

The usual cause of a runaway is oil in the intake from a worn turbo, it can happen to any Diesel engine and shutting the fuel off won't stop it.

This I understand however, when the turbo was sent for renovation the garage said there is nothing wrong with the turbo. I can renovate it but you will be wasting your money. Plus, I'm not too sure but would the signs of this worn turbo be that the engine pulled back and then started to rev up?

[Crasher]

Signs of a worn turbo are large amounts of oil in the charge air system. Failure of the tandem pump into the oil will make the oil level go up and eventually the engine will run on the overflow. Does the oil level go up?

The oil level is not going up at all. The mechanic even made the dipstick white, so that it's easy to check the oil level precisely. I'm checking the oil level every morning before going to work and every day when leaving work, its bang on the same mark every time. I need to find out which pump he has changed, but as mentioned earlier, the mechanic mentioned that there was 5 litres of diesel in the oil sump (the last time the engine ran away). The mechanic said if the oil level doesn't go up at all then the pump he changed (the last thing he changed) was the problem. I might be back at the mechanics at Wednesday and I've many questions to ask him, it's just a matter of having the time to go there. As for the EML light and glow plug light, I'm thinking this could be a different, unrelated problem. For example, maybe he didn't put something back together correctly, a connection, a sensor or what have you, what do you think?

If he changed the tandem pump that will probably be the end of the problem.

I'll ask and see what he says. In the meantime, regarding the lights, I'll throw that one back at the mechanic. Nothing else I can do, as I don't have the money to buy a VAG-COM from ross-tech, especially with the money this repair has eaten up. That and the fact Christmas is coming up. Although I'm convinced it's unrelated now, as I've read through some articles on here where limp mode has went on or there's been some change in the performance, MPG or something or other. Our car simply doesn't perform any differently, plus the light is intermittent. I'm suspecting an evasive fault anyway, as the last time these lights came on before the last runaway problem the errors were probably accurate. Plugs were showing low voltage (plugs 3 and 4) and now all four are showing voltage 14.4 but coming back with an error. Plus, injector was showing faulty but since that has been cleaned I've had no errors coming back that either. Is it possible that with so many faults showing it's the wiring loom?

We need to know the codes stored.

Unfortunately, what I previously posted is all I have. I'm using the 12.12.3 version of VAG-COM with a dongle from amazon. I've no opportunity to use anything else, the mechanic is using a Bosch wireless scanner with some professional program that probably costs a fortune.

And all the other faults too, not sure about them, if they're real, or caused by the other faults.

The rest is Engine Control Module, what could this be? seems be giving everything no signal or intermittent signal.

Have a new V157 and 4 new glow plugs fitted, then see how it goes.

[RichardSEL]

If mechanic is using a generic scanner then he's either not a VAG-trained mechanic, which you should be employing, or using the wrong kit.
The kit is either VAS the VAG Group proper scanner that also speaks to the VW mothership for retrieval of car records and update flashes.
Or the appropriate version of the real VCDS -- not as expensive as some think -- £200-odd from Gendan inc.

VAG Group cars use not only the generic "P" codes but also sub-sets of them that tie in with the Ross-Tech Wiki and give more detailed fault finding hints.
Ross-Tech Wiki (http://wiki.ross-tech.com/wiki/index.php/Main_Page)
The VCDS public forum (on VW Vortex), their private forum, and email reply service are worth the outlay in itself!

Oh, BTW no commercial interest here. Just a satisfied customer who saved hundreds when, a few years ago, got told how to handle a dealer over a warranty claim :beerchug:

[MarkC89]

Sorry I've not posted back about this.

Update: It's SOLVED!

I took the car back to the mechanic after driving around with the flashing lights for a long time. He's fixed the problem with the glow plugs (some kind of wiring problem). As for the V157, he raised this issue and said it need's to be replaced, and until then the light will come on and go off intermittently, which it does.

It seems that the replacement of the oil pump has fixed the issue of the oil and fuel mixing and then becoming a runaway.

Thank you all for your help
