Golf 118 TSI Engine Failures and Service Campaign 24S4

[brad]

If anyone is familiar with VW replacement policy for their 1.4 TSI twincharger engines under warranty: I would like to know what parts exactly did VW replace when they replaced an engine due to block damage (caracked pistons and cylinders) ? Did they only replace the engine block, or did they also replace injectors, spark plugs, coils, pumps, and (most importantly) the ECU ?

.

ECU definitely not changed. No reason to do so. If the software is at fault they re-flash it.

Thanks, what about injectors ? Together with the pistons (which should come revised with the new block), those were the most expensive parts which had to be upgraded to improve reliability.

I don't know.

To the best of my knowledge the pistons were the issue (apart from the crap tune). I believe some of the oil burners just got revised pistons in the original block.

If you were lucky enough to score a bore then the fix appeared to be anything from a short block to a complete crate engine.

Ok one more question: what major parts would a complete crate engine from VW have contained ? (Aside from the block, internals, gaskets etc.)

Camshaft + variator ? Injectors ? Timing chain ? Fuel pump ? None of the above ?

They only replace damaged parts so it depends on what was found at the point things were replaced. In my case it was only the pistons as I caught it very very early.

[vw4ever]

Thank you for the info. However for cars with a "new engine" replaced under warranty, meaning probably a "complete crate engine", I would be very interested to know what this complete crate engine actually includes. What's the best case scenario ? Camshaft + variator ? Injectors ? Spark plugs, coils ? Timing chain + pumps etc. ? Fuel pump ? Hopefully someone who has had his complete engine replaced knows this.

Received this diagnosis today. What could be done rather than replacing with the secondhand engine - which might cause problems again in the future? What could be the real problem inside the engine? could you suggest?

Vehicle: Volkswagen - Golf, Year : 2008 Mileage: 139423

Check and found engine misfiring and smoking, turbo noisy. Engine light on. Check for fault
codes. Found 00772 active/static cylinder 4 misfire detected. Removed number 4 spark
plug. Found spark plug oiled up. Smoke coming out of cylinder. Carried out compression
test 50psi, number 3 175psi. Suspect piston failed.

NOTE: Recommend engine and turbo to be replaced.

VW doing it as a goodwill is obviously the best option if it’s at all possible. Even if they only cover some of the costs it could still be viable (or more viable). Have you contacted a dealer yet?

That leads to the second option of finding a second hand engine and throwing it in as cheaply as possible. Ideally a later model with revised pistons. From there you either take the gamble that it will give you another 11 years and keep it as is or you sell it on and buy something different.

The last option is to attempt to sell (or trade it in) as is and let someone else deal with it. This is the 'cut your losses and walk away as quickly as possible' sort of option and is likely to be the most costly.

[vw4ever]

If VW won't cover it there's also a third option: rebuild the engine. If the cylinder is damaged, bore the cylinders to 77 mm and buy a new set of revised pistons (77 mm), either stock (Kolbenschmidt) or forged (Wossner, may also be others (?), about double the price). Might be cheaper than SH engine and may also be more reliable if you use forged pistons. However you have to find a good reliable shop that will do the job, one that ideally has done it before with success. You might also want to upgrade some other engine parts while you're rebuilding, there are people with great knowledge on the subject who may give you suggestions.

[The_Hawk]

rebuild the engine.

Thanks vw4ever, I always forget about that one. Also a very good option if, as you say, you can find a good shop.

[vw4ever]

Indeed, it's a big IF. Only look for good, reputable shops that have done this thing before, ideally also lookup a client of such a previous rebuild and see how happy they are

Adding another lemon to the list

My VW Golf TSI118 I bought brand new in 2010, had the engine light come on back on Boxing Day. After getting it towed back to VW dealer I originally purchased from, they have confirmed the #4 piston head is cracked and they'll need to rebuild the engine. The good will claim to VW got knocked back because the car is "too old". It's just done over 100,000 kms. What a joke.

If you can prove it has a valid service history then I'd go to the ACCC and find out what your options are. I'd then pay for an official looking letter from a solicitor sent via registered post.

It might take months and can u afford to be without the car for that long?

I'd also contact VW direct - in writing.

Hi.

Adding mine to the list 09 golf, engine replaced at 22k kms(i bought it at 24k)
Before xmas engine light and confirmed lost compression in cylinder 4. (Car is under 81k km)
Currently with VW and has already been denied once for goodwill due to age of car. I have disputed the decision and awaiting the outcome. That said, as someone else has mentioned, under Australian consumer law and Consumer guarantees i dont believe 10yrs on a car, 7 years on an engine with 59k kms is reasonable?!

No it isn't.
