Golf 118 TSI Engine Failures and Service Campaign 24S4

[Guy_H]

I just paid the cash & logged onto erwin

and had a good look around with 118TSI VIN numbers & engine code & can not find any "campaigns" on engine failure / replacement.

Mid you, it can take a long time to filter down to this official VW technical site. Maybe Australia is ahead of the curve?


Maybe a post with actual owners with actual failures would be good to focus the extent of the problem.

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.

Well that eases my mind a little - as soon as our 15k service is done I'll be getting a flash. I plan to just leave the car in "APR mode" all of the time as well.

Interestingly, our car seems to be not the best on economy compared to the claimed figures - it's close but isn't miraculously thrifty no matter how "economically" by the book I drive it. Whether there's different states of tune out there, or whether it's an actual manufacturing defect with something else causing these dramas I'll probably never know, but I'm sure as hell keen to find out.

In my experience, the twin charger 1.4L engine isn't that great (wrt to fuel economy) for stop/start city driving, it gives decent economy but is no where near small car levels. You must remember that the MkV and MkVI golfs are heavy cars.

Where the 1.4 TSI engine truly excels for fuel economy is when you use it for long distance driving. I average between 550-600 kms per tank (city driving) but get 750-880 kms per tank for long distance jaunts (carrying two persons with a packed suitcase weighing approx 10-15kg).

Or maybe it is something about Australia. The "tropical" situation that denies us 199kW Rs and BlueMotion may have a ring of truth to it.

My wife's 118TSI has to go in for some minor warranty work (a 3rd brakelight) Talking to the technician I said something along the lines of " it's minor, not like an engine failure" he said," How did you know about that?"

I notice you live in Sydney which can be quite hilly. So this depends on which Sydney district, but generally I would expect Sydney drivers to be getting worse economy compared to cities that are flatter such as Melbourne.

I live in a particularly hilly part of Sydney & commute between hilly parts (nw and eastern suburbs) and my long term average seems to be around 7.4 l/100km - and I'm not exactly sparing with the throttle either ! ; )

I think that's a fairly good effort for predominantly suburban driving.

In non-peak commutes I've seen comsumption bang on 6.5l/100km.

Flatter areas in Sydney such as around burwood / rhodes / some inner west areas / bankstown should see better figures as they're flatter.

I haven't read/heard of the MkV GT/GT Sport engines having the same issue. Like others have said here, it might be the OEM tune (in the bid to improve fuel economy) of 118 TSI that is causing the issue.

OR VW may have gone too far in it's quest to cut costs in the MkVI that they have compromised reliability.

I looked to see if there were problems with the twincharger engines in the GT before I put my money down, and there just weren't any reports. Mines fine, but I would like to see the resolution of this problem.

Most of our commuting is in the CBD and Inner West, we do encounter some slight undulation but nothing major. The total average for our car is about 10l/100km. Probably thanks to all the traffic, but either way quite thirsty in my opinion. Will be interested to see if this changes after the "software update" they do at the service.

Wow that does indeed sound unusually high. Perhaps you could reset the ECU back to learning mode by disconnecting the battery for 30 mins, and then see how it goes from there?? You'll lose your radio stations and non stock MFD options, can't see any other downsides??? People???

I don't know... what goes up, must come down
Sure you use more fuel going UP the hills, but if you drive correctly, you don't use ANY fuel going down the hills. If you're above a certain RPM, in gear, no accelerator, the car's fuel supply is disabled.

yeah constant stop start traffic will murder fuel consumption. Also factor in hot weather so the aircon works harder. I can get 10 in cbd driving in summer on a trip. If your trips are very short your average will be high as each time to engine will use more fuel during warm up.

If you really want to put your mind at ease try driving out from inner west through west city link then up victoria rd then back down to parra rd via centennial drive. Maybe do this outside peak weekend like in evening. You should get below 8. Thats a mix of stop start and semi freeway conditions.

Today from nw to east i did 8.3 via gore hill but its a warm day and i used aircon rather than open sunroof and traffic was heavy in spots.
