Golf 118 TSI Engine Failures and Service Campaign 24S4

^^ What he said.

No probs at all with mine. Works like a charm.. I have never used anything but 98 in it, and lately only fill up with BP from newer petrol stations.. But then i don't trash the crap out of my car every time i drive it either!! and never give it any boot until the engine is warm.. A lot easier to be gentle to the engine in a manual.

tell me about it! the ability to control revs is huge for me in my polo tdi which takes 10kms to warm up.

With the point regarding the engine running overly lean, would you think that an aftermarket tune, let's just say an APR chip for arguments sake, would fix this issue? I would assume that APR when doing their tuning would have modified the air fuel ratios throughout the rev range, perhaps in fact making it run a little richer due to increased boost?

Anybody have any solid info on this?

I think that only someone like Guy H would probably be able to speak to that.

My car has been faultless too... 1.4 twincharger early GT motor.

I think there has been some re-engineering for profit "RFP" on the newer 118 TSI's hence the squeek and other issues.

I think the early GT, GT sport 1.4's are the strongest as they don't squeak and have had no failures as far as I am aware.

The first oxy sensor controls fuel trim to achieve 14-14.7:1 and the second only checks for temperatures and cat efficiency. So you only need the first one to fail for things to go up **** creek as far as the documentation I have on the engine goes.

My wife's 118TSI has also been fault free.

Surely a Lambda sensor failure would throw a fault code on the MFD and put the ECU into limp home mode before there was any damage. Also, I would have thought an excessively lean mixture would burn valves before it softened a piston sufficiently .

I would think a ring failure due to insufficient end gap would be more likely with piston failure secondary to ring failure.

I will be watching this thread with interest.

What about opening up the oil filter top using a cutting tool like they use in general aircraft maintenace and then seeing the metal shaving and bits etc stuck on the filtering paper itself?

When you see metal bits on the filtering paper then you know the engine is up the creek.

While Guy has a lot of experience with VAG engines, it'd be foolish to suggest he has a monopoly on said knowledge...

So are they going to do a recall on these engines or what's the go? Surely the new 118TSI Golfs on order and coming over in the next few months would have had the problems fixed?
