My B6 engine died :(

[JarGon]

3 days ago driving home in my 56 Plate Passat 2.0TDI Sport and the coil light flashed for a second or two the the engine cut off, still had power to lights, ignition etc. Called RAC and went on a few forums as i was waiting for him to see if i could find anything similar. So eventually found loads of posts about injectors giving up and though thats exactly what mine is!

So he turns up and plugs his laptop in and sure enough it comes up with injector error plus a few he couldnt figure out. It got towed to VW Letchworth and they called me yesterday saying it needs:

2x Injectors £1360
Loom £124
ECU (maybe) £1028

Not to mention

Service £204
Rear pads £129
Bushes £299
Plate bulb £26

Trust me i was not happy hearing this lot!!!:mad:
My car is warrantied up to £1000 but they dont believe what VW are saying so are sending someone to check it.

I can get my hands on used 07 VW Golf 2.0 (petrol) injectors or 07 Audi 2.0 (diesel) f.o.c anyone know if these will fit my passat?

[rapport25]

Injector and looms are common I'm afraid :(. Touch wood mine has needed neither. How many miles has yours covered?

Please see a previous thread I started http://www.vwaudiforum.co.uk/forum/showthread.php?t=110025

[rapport25]

With ref to injectors they will need to be Siemens pd injectors for a diesel. Unfortunately they are dealer only :aargh4:.

[JarGon]

Its currently on 106000 never given me a problem until now


Has anyone ever had to do the ECU aswell?

[martin1810]

It is unlikely that the ecu has failed. Injector failure is fairly common. It probably doesn't need a loom but dealers like to change it at the same time. It costs more to change it later.
Only injectors with the exact same part number can be used.

[gireada2005]

i think someone on this forum said he bought reconditioned one ,used it for a year and they are still going i think it was this one http://cgi.ebay.co.uk/DIESEL-INJECTOR-SIEMENS-03G130073D-M-REPAIR-/290524377307?pt=Automobiles_UK&hash=item43a49a30db. very sad to hear that,,goodluck anyway

my car died two days ago and will not start, auto spark recommends new loom looking for a wireing diagram for 2006 2.0tdi passat?:aargh4:

Jar what bhp is yours? 140?

[/QUOTE]

Why is it that so often I am reading more than one injector is needed? Do they go out in sympathy with each other? or is this a diagnostic issue with VAGCOM saying 2 have failed and they dont check them with a meter as martin1810 suggests but just change them?
Glad you have a warranty for hopefully most of the cost. Perhaps extended warranty's aren't as bad as some people think.

140 bhp engine. Can anyone help on how to test injectors as ihave disconnected them individually and cranked engine to see if one is down, but how do you test to find out if two or three have gone down. The car has just done 102000 miles with full history. can anyone direct me into what else to look for? many thanks

I wondered that too - either that, or they are betting that if one has failed, another can't be far behind? Its mostly injectors 1 & 3 that are failing, isn't it?

[paulpablo]

Please help, if anyone can give me a tread for the wiring diagram for a 2.0tdi 140bhp passat sport i would be eternally greatful

[martin1810]

The injectors are wired in pairs so a scan will always show as two being faulty. Most garages are not going to" meter test" the injector until you agree to pay for the work.

What wiring diagram?? An injector wiring diagram won't show you anything. Just a couple of wires an injector and the ecu controller. Nothing useful.

[paulpablo]

The auto spark has ask me to get a full wiring diagram of all the cars elctrics as he suspects that the loom of the car is to blame?

Can u direct me in any direction?

AS i have removed each wire going to the injector and cranked the car still wont start.

Any other test i can do?

vag com reads three codes 18598 17925 18808

need to fix soon as it is a private hire taxi:banghead:

[martin1810]

18598 P2166 Throttle/Pedal Position Sensor 'D', Maximum Stop Performance
17925 P1517 Main Relay (J271) Circuit, Electrical Malfunction
18808 No such thing.

Why look at injectors. You don't have an injector fault code.
Was this scan done with VCDS because the codes are for a petrol engine car.
J271 is the petrol engine ecu relay.
Crap scanners often give nonesense like this. J271 probably means J317 terminal 30 voltage supply relay..
Open the bonnet. Open the black square box near the air filter. Check the fuses and pull the relays out and push them in again. That might do it.

Been back in touch with the auto spark and told him what you have said in the forum and he said the codes are 18578 and 17925 and 18080 he made mistake still scratching my head with him and have now been given vcd to use off me mate who owns the car showroom from were i bought the car. I have unplugged each injector again today and tried to startthe car no joy. If it is two injectors down how will i find out?:zx11:

[martin1810]

18578 P2146 Supply Voltage for Fuel Injector Group A, Open Circuit

18080 P1672 Coolant Fan Control 1: Open or Short to Ground

There is a good chance you don't have an injector fault. You definately have a relay/fuse or broken wire fault. Probably on the terminal 30 relay. Have you checked the fuses and relays in the e-box, in the engine bay.

were is the terminal 30 relay positioned in the vehicle? Just phoned autospark and he did not know were or what it is? And do you have a part number?:zx11: I would also like to thank you for the help you have given me Thanks martin

[martin1810]

Look here for picture of engine bay e-box.
https://sites.google.com/site/1810martin/passat-b6-fuse-assignment

The terminal 30 relay may be at position shown as A1. If you don't have a relay there, it will be a "bridge" which means the relay is under the drivers dash. Look at the fuses in the same box. Just about every diesel VW uses a terminal 30 relay so perhaps you should find a new person to look at it.

I think you need proper eyes on it, from your posts your autospark guy doesn't seem to know much about much tbh.

Isn't there a method of disconnecting each inj seperately, and when and if the engine fires it's the disconnected one at fault?

[JarGon]

So here's the latest!

I picked the car up last Saturday at a cost of £1400+ for 2 injectors and a loom and intermittently the coil light flashes and brings up the message "Garage. Engine Fault"

This morning was the worst, was driving to work (35miles into London) and it must have done it over a hundred times!

I called VW a few days ago and it's booked in for Monday but I really can't see it lasting that long so I'm going to call them in a bit

Wish I never bought the damn thing, should have bit the bullet and bought a brand new Mazda6

Any ideas what they might have done wrong? Not set up properly maybe?

[JarGon]

So the latest is; I took the car to VW Letchworth again, they checked it and said it had too many faults recorded so they cleared them all and said it requires a road test which they did and guess what? No faults came back? So I said road test it again which they did for 17miles and still no fault? The only thing mentioned was it was quicker than a standard 140 ;)

Strange? I think it was not cleared to begin with but I'm just happy it's running again!

[JarGon]

It did it again!!

Started the car and bong "Engine fault Garage" coil light flashing, turned off the engine re-started and bong same again but exhaust light is on now as well!!! ***?

Took it back in to VW this morning, let's see what they say this time!

[richball65]

VCDS is generally correct in my experience. I had a couple injectors go a week apart before and after christmas.

I too have read someone where that it is common for 2 to go at once


Expensive job....I know !

[martin1810]

They don't fail in pairs The ecu controls them in pairs, so a fault code read will always point at a pair of injectors. This leaves people thinking that "pairs" is important. It isn't.

[Astonm]

I think I have an injector fail but I have had no warning lights. I had a warning lights last year but VW changed the wiring loom and all was ok, still had the odd "miss" at 2000rpm.

AA towed the car to VW last night waiting for that dreaded call now. Can I ask people that have had new injectors did you notive an improvement in the engine after (apart from it starting that is :-)?

[PatMcCoy]

Had one done last week no warings just stalled next morning engine fault garage if i tried to start it it came stop
No differents at all

[tigertank]

I am glad of warranties bought my '06 tdi se 140 estate on 30/4 and blasted heap of sour crout has spent more time in garage than being used.
It has had an injector fail, and been replaced (89K) and is also needing a immobiliser/steering column lock, and this because of the blasted recoding of every thing has to go to a mean dealer where they take the **** to the tune of £83.50(exc) /hour, and warranty only covers up to £45/hr. have had to get tough with selling garage to recoup the £130+Vat i need to pay to get my car back.
I am personally very glad that many things in life are more reliable than a VW, like for example our trusty'57 Morris 1000, without which we would have been immobile for most of may.
I thought I'd buy a decent second hand car and spent 7K on this one, I wish now that i'd bought an old sweater you can walk away from after a year owing you nowt
