Turbo problems on Golf 150 TDI

[porchie]

Really would appreciate some help although I am already looking at worst case scenario of a new/recon turbo but just wanted to check for other ideas from everyone on here?!

I have a 2002 150 TDI that has covered 37k miles only and has been regularly serviced etc by the previous owner. On my way home the other night it was stuttering and as it was a short trip from work I left until the morning and as soon as started up and revved above 2000 rpm there was loads of smoke and no power. Is it automatically the turbo that is gone as I find this strange at such low miles?? We've had the similar sysptons on Vectra 3.0 V6 TDis at work and it was a turbo inlet hose but obviously have never looked at issues with Gold diesel turbos. Do I reach deep into my pocket for a recon turbo straight away or could someone suggest anything it might be other than the turbo?? If the turbo then where best to get one at a sensible price and is it fairly easy to fit????

Thanks guys as rushing into work now so no time to research and need to get the car sorted as soon as.

I think you should reach into your pocket for a fault code read first as that sounds like a faulty coolant temperature sender to me. The turbo on the 150PD ARL engine is extremely unreliable and prone to premature failure unless the oil changes are carried out twice as often as recommend and even then they fail. I have seen them fail at half the mileage yours has covered but as I said, a £30 fault code read first.

Hi mate it could also be a boost leak or one of the intercooler hoses,they have a issue with them wearing the lugs out on the end of the pipe what the clip sits behind and when that wears enough you can start having issues with them popping off at various not needed intervals and with the vehicle having big engine shield on its not an easy roadside repair.

Would a hose cause a huge amount of smoke then?? Are we talking about one of the larger hoses???

Thanks

Yeah this does cause smoke and serious serious power loss,i would check all the hoses to make sure there seating up against what the need to be ok,there is one on top of engine to EGR but that is not normally the problem,its normally pancake one under wheel arch to rubber intercooler hose on drivers side or where that one meets cooler or vice-versa on other side.
trouble is diesels run about 1bar of boost which is pretty high for such poor hose connections instead of using hose clips etc,there is a couple of hard hose kits available but there not cheap where as others have made brackets of used a webbing of hose clips n cable ties,not the perfect fit but it works better than some dealers i have been told used to try n screw through the intercooler end and into the pipe while in situ but that was only one dealer i have heard of

Sorry to ask so many questions but is it a question of removing the inner arch to get to this pipe?? Do you know of any detailed instructions for removal and refitting etc if thats the worse case? I might get the RAC out to do a quick diagnotic if that would be a good idea????

When those pipes blow off the smoke the car pumps out is unbelievable, it will cover the road in black soot. One is accessed from the driver’s inner arch after removing the lower and corner covers but the other is under the radiator, either is prone to failure. You shouldn't really use the RAC like that; it is time to take it to a garage.

Again agreed with crasher even if RAC do come out they will only be able to tell you if they can see the fault there is no real temp repair if the lugs etc are worn,unless you get them to take your car to a garage you trust,or jack the car up and remove the shield to see if you can see any of the pipes hanging out or not connected properly just to make sure someone doesnt try to charge you for turbo replacing etc if that isnt the problem

I was only thinking aloud and I will strip it down in a bit and have a good look and fingers crossed it will be a pipe although I bet the ******* will want loads for the parts even if only a pipe?! I would have thought if the turbo had gone there would have been more noise when it went so thats why I am hoping its just a hose etc. Appreciate your help guys.

Agreed mate i myself working with cars everyday understand what others dont,where people penny pinch going to aftermarket sparky's etc and other garages with diagnostic machines what cant even read the codes correctly so your no better off when you have paid them,if you have a friends that can do this work and is good at it then bonus,i think what scares people is the dealer labour charges on some vehicles but its the understanding that these people work on the car everyday and if its a common problem most of time its things they can just about diagnose with a decent description of problems over phone in our case plus if the work comes to them after the diagnostic they never get charged for the diagnosis itself,will read your page later cos was gunna ask what you do seen as you seem wiser than most(dont get big headed though lol)

I have just had a similar problem with my 150 lots of smoke and a misfire, it was a intercooler hose that had partly come adrift, hope yours is as simple.
