Golf 118 TSI Engine Failures and Service Campaign 24S4

[triode12]

Thanks guys for the information!

This has been an interesting thread so far, and I thought to add my little bit.

What would be the long-term effect of running one of these engines on lower octane fuel?

Not necessarily 100% ULP, just an under spec. mixture.

It seems the pistons aren't melting (a frequent result of excessively lean mixture, albeit usually accompanied by burnt valves), and prolonged detonation might well cause ring lands to fracture.

This wouldn't necessarily mean the vehicle owner economising on fuel, either.

Many years ago (before the advent of unleaded) I had quite a bit of involvement with the petrol reselling industry and it wasn't at all rare to visit a site in the wee sma' hours and see a bowser busily transferring its load to another tank.

If asked, the story was always that the tank was nearly empty and the tanker wasn't due yet.

Odd that it was always a 'standard' pump, though.

I don't suppose the leopard's changed its spots all that much down the years...

My car, with a new engine, was returned to me this am. Cylinder 2 was the offender. This is the 4th 118 TSI engine that this dealer has replaced.

Glad you've got your car back, Intensive. Hope that's the last of your problems.

Wow - that's more than I'd like to hear about really!

What happens to the broken rings and damaged engines? Are they shipped back to Wolfsburg for analysis?

More Info:

Believed to be 10, 118's failled (not sure if all the same) in Brisbane, and one had APR software (9 stock).

[Corey_R]

Have you had a chance to inspect the one with the APR software Guy?

If I were to run APR software on my 118, and the engine failed, would I be left out in the cold with no warranty? Or will VW still honour the warranty?

No, but speaking to the tech's the fault is the same on all the engines (as described earlier in the post), nothing to due with tuning of any form.

Same as any modification & any warranty, NO unless the modification is proved to be the cause. From what this post is saying there seems to be a recognised manufacturing problem & there are several cases with the same failure. No one is left out in the cold without warranty, form either VW or APR.

He's right and realistically the stories what we're hearing from our customer cars & contacts is that its more common then ever now.

Had another last night, came BACK from a dealer and is worse then before, 14k on it and second engine already.

Simple though with a Chip, if your paranoid dont do it.

MAN! I might have to cancel my order. This is getting worse every day!

Anybody have any idea what the ratio DSG to MT 118TSI failures have been?

The 118TSI DSG I drove 2 weeks ago for a few days had real issues downshifting going down and then up a hill ..... on the way up it sounded like it was stalling and pinging (detonating) as it was in too high a gear to make it up comfortably .....

[sambo]

and another to the list....

a relative bought his 118TSI less than 12 months ago....it has been back to the dealer on at least 6 occassions each time was as a result of the engine light coming on...each time they could not find the fault....until...

6 weeks ago he noticed a distinct drop in performance...car was taken to the dealer....and the problem found as a split piston ring, cylinder 3 or 4 from memory...this is now apparently fixed/repaired.

car is back at the dealer because he is now having problems starting it.

not a happy camper

I note what has been said about the general air/fuel mixture situation and the resultant damage this can cause if its not spot on.....however can i throw my 2c in and say (what may turn out to be a silly statement) but i have always held concerns about this engine in so far as being obviously small in capacity with bolt on equipment in order to increase the performance.

Is it the case of asking too much from a 1.4?...please feel free to shot me down if i am way off the mark
