118TSI - General Discussion

[Mountainman]

Good point, although I haven't seen any MK6's north of 100k yet at all.

My brother's Jetta 118 TSI DSG bought new in late 09 has just hit 110,000km and has had a complete engine replacement (just over 50,000km), then new pistons and rings (95,000km) as well as 2 clutch packs and a mechatronics replacement, all under warranty. I reckon VW didn't make much on that sale.

I think older 118 had bad spark plugs leading to misfires that weren't detected by the driver. Years down the road engine failure. Haven't really heard of engines with the new spark plugs getting this issue.

I've had the pistons and injectors replaced, but as far as I can tell I still have the old spark plugs. I need to do something about that.

A thing to note is that you can change the gap on them and you would be ok. The gap should be 0.8 mm according to Vw. Older plugs came gapped at 0.9 mm

The spark plugs were the first thing to be replaced with the new type long before it had to get the first new motor. One positive thing was how good the sevice people were trying to solve the problems. Even then the new engine replaced in 2011 didn't last as long as the original. Surely VW must have done long term tests on these engines before releasing them onto the market? Such a nice car when things are going right too but one day he will not be able to keep forgiving.

If 0.1mm (0.004"??) is the difference between the engine grenading & staying together then it must be more finely tuned than an F1 engine.

The misfire that occurs is very small. Mostly unnoticed by the driver. An engine that is seemingly running fine is misfiring unbeknownst to the owner and is being damaged slowly. Spark plugs are finely tuned things anyway. 2mm is a lot with spark plugs.

I can imagine VW's result being a lot worse if they used the 118tsi engine in the US.

I reckon the old 2.5 NA engine they use is artificially suppressing their faults per car figure when compared to the quality of their average vehicle sold globally. I also believe their Golf doesnt use the DQ200 DSG but the slushbox... Which further artificially deflates their faults compared to what is offered in the moajority of countries.

I better start saving up for a Lexus or Porsche then

I agree

It probably helps that their car isn't a 118TSI with the 7-speed DSG.
