Well i posted the other day about having troubles after a remap, this was done on a 3 week old reconditioned turbo which happened to work fine for 3 weeks until an hour after the remap! all work including remap was done by the same garage. Work included: engine flush, new oil filter, new oil lines for turbo and the reconditioned turbo.

Took the car back today and left it with them, got a phone call saying "its turbo problems again, its nothing to do with the remap, its something to do with the engine", my reply to this was that i hope i havnt got to fork out for a new turbo after 3 weeks! Got told that they need to drop the sump and check why the engine is killing turbos and that they were going to try and claim warranty on the turbo but couldnt promise anything.

Surely before the turbo was fitted they should have checked to see what made the old turbo fail? and does the sump really need dropping when they have already suppposedly flushed the engine?

Any light on the matter would be massively appreciated.

Another thing, does 1.5 bar seem like too much of an initial boost spike after a stage 1? this quickly settled to 1.3 bar though

All the old oil should obviously have been removed when the fresh turbo was fitted. Also, the intercooler should also really be removed and flushed through, in case there are any fragments from the failed turbo.

I certainly wouldn't have recommended running it in remapped form immediately after the turbo was swapped either, at least let the unit bed in first.

Yes way to much boost!!!!!

Prob oil pickup thats blocked and yes should really find why the turbo failed first !!!

Thought 1.5 did sound like a lot, but don't have much experience of 1.8T mapping....

If they have just literally done that work for you and fitted a fresh turbo, then it's a bit worrying as they've potentially not yet unearthed the proper cause of the original unit's failure! How long was the car with them for?

99% of turbo failures are caused by an issue not with the turbo i.e normally oil supply over spinning etc etc

I'd also be curious to know what a visual inspection of the dead turbo revealed - presuming the garage did that!

Chipping, cracking, excessive play etc etc...........

The problem with the original turbo was bent compressor fins, i pulled out my compbrake dv and noticed the piston oring had gone bye-bye which im presuming got sucked into the inlet and had bent the fins. The turbo still boosted well but very noisy! They had the car for 2 days, did all the work and its worked a charm up until it was remapped :(

My issue is i believe it was the excessive boost from the remap that has maybe caused some damage to the turbo. That was a big question i asked before the map... "is it wise because you only fitted the turbo 3 weeks ago, or should i wait?", "No it will be fine!"

But they are trying to say its an underlying fault with the engine *cough* bulls#*t *cough*, am i right in thinking there should be no charges for them to rectify this mistake as im going to be pretty annoyed if ive got to dish another chunk out after the last turbo!

Who did the work for you?

The problém is mo?e likely a blocked oil pickup and to be fair as your previous turbo failed due to it injesting something so there was no need to check oil pickup!! Boost level is high but dont believe that would cause failure so fast think you have either been unlucky or the new recon turbo was crap.

fingers crossed it gets accepted for a warranty swap then!

As Clive said it's most likely been starved of oil.

Running 21psi boost pressure won't have done it any good as it will have been running a lot faster than a new turbo probably should.

Combine that with a blocked oil strainer on the pickup and it's a recipe for a shagged turbo.

Surprising they didn't check the oil strainer before they fitted a new turbo as this is becoming more and more of a problem on these engines. As the old turbo was killed by foreign object damage rather than oil starvation they probably didn't even give that a second thought though.

Sorry to say it but I don't think the warranty will pay out and you'd have to argue the toss with the garage to get them to fit another turbo for free, its just bad luck that the oil pickup blocked when it did :(

At least if you speak to trading standards you will know exactly where you stand.

I would have a chat with trading standards. If the garage get arsey then say you are having a chat with them as you potentially feel the work wasnt up to standard and that the turbo fitted, wasnt fit for purpose.

Trading standards will know exactly where you stand

I think, unfortuantely you may be a little stuffed here. I'm not an expert on these engines but I am a master technician with another make...

When you had it re-mapped, did you have to sign a disclaimer? If you did, you have no come back on the map causing this issue.

I've never had a reconditioned turbo thats gone back under warranty and been accpeted.

Trading standards will find it very hard to do anything. Most they are likely to do is write a letter to the garage setting out a case for you, as you've told it to them. The garage can pretty much ignore this.

I think the best you can hope for is the turbo supplier accepts responsibility and sorts it for you, if not try to get the garage to cover any labour and you cover parts, also ask them to put back to a standard map.

Obviously I'll keep an eye on this thread and answer any questions you may have to the best of my ability. Just remeber, I'll not try to lay blame with anybody, just advise you of the best course of action.

Chris.

Did you pay with a credit card? Some items purchased with a credit card aquire some sort of guarantee but I can't remember all the details. Also the items supplied by the garage should have been of merchantable quality, fit for purpose so make sure you talk to trading standards

I didnt have to sign a disclaimer for the remap, and all the work was payed cash, with a printed reciept issued.

They said that usually the company that supplies the turbos is very good with them, probably due to the amount of business they give them, so hopefully i might be lucky and get a replacement. If it doesnt get replaced under warranty then the car can go, not willing, or financially able to pay for another replacement unfortunately :(

what makes you think the boost pressure was running so high? My boost gauge shows 25psi on my stage 1 map, it's over reading like **** lol

unlucky.. hope you get it sorted.

thats a point, suppose the gauge could be reading wrong!

Silly question but if the oil feeds for the turbo were replaced when it was fitted then is there still other causes for blockage?

Yes, the sump pick up. This seems to be number 1 cause of turbo failures on the 1.8t. You can't 100% trust your boost gauge.

Did you get an oil pressure warning light before either of the turbo failures?

The work they carried out should carry some form of warranty.

the oil pickup is in the sump and they would have had no reason to check it or replace it unless instructed by you!!!

if it was the cause then i suspect you will have to pay out but you need to see why the turbo failed and how its failed !!! who did the recon ??

1. what made you go back loss of power or smoke

2. how many miles after fitment did this happen

to many variables to point fingers im sure they will do there upmost to help you.

There was no oil light before this happened. The reason i went back was an aweful loud siren noise and absolutely no boost. Gauge would go from vacuum but stop at 0 bar. All was well driving along then pulled off from a roundabout with no boost and the noise, it wasnt even progressive

If I had to guess I would say it was a fault with the reconditioned turbo.

These turbos run on a pressurised oil bearing so there is nothing to bed in.

They replaced the oil pipes to the turbo, so unless you got a flashing red oil pressure warning, you can rule out oil starvation.

Let the garage claim on the warranty. If the turbo company turns down the warranty request, they should give you a reason.

Thanks for all the input, ive been worrying about it too much and my head hurts now

Fingers crossed it gets sorted, i'll post the outcome when they get in touch
