118TSI owner

Tigger, Half my problems is the replacement engine. Like I said, I purchased it a while back and never got around to inspect the internals. Well, I finally did, and it needs to be taken apart and cleaned. So had I taken it to VW to fit, I doubt it would have lasted a month on the road. With the number of K's on the clock, the age, I would be lucky to get 8 or 9 on a trade in. That's a 10k loss right there. Plus the cost of a new clutch n flywheel, belts and any other bits and pieces it may need. I think I would easy be up for 13k loss and be without a car.

I rather take that 13k and put it towards something I know works.

If you take a look at what VW has done to try and fix these engines, you can see where the issues are..
ECU remap to better suit Aussie fuels and power reduction
Uprated high pressure fuel pump (I have both the old HPFP in the old engine and the uprated HPFP in the replacement engine)
PCV improved
Sparkplug gaps changed
Pistons improved
piston rings improved
and now I just read on here that the Oil squirters have been improved too.

My understanding is the most common cylinder to fail in 2009 models was piston No.4 which is the furthest away from the HPFP. the weak pump struggled to feed sufficient fuel at high loads and in particular when cornering, and uphills. So, add all 3 together (like when entering a short freeway onramp) and you have pinging....

Of course, cylinders 1 to 3 fail too, but number 4 was the most common. The Nikasil coating on the cylinders is too tough for the piston rings VW decided to use. With the added pressure from hot pistons, pinging etc caused by the poor circulation of oil from a failing PCV, poor piston design, and (from what I just read) bad oil squirters, the poor rings don't stand a chance.

By improving fuel supply, oil circulation, ignition, pistons and rings, these engines should last a life time. Everything else that I want to add or improve (from better conrods, supercharger, turbo etc) is purely for performance only. So I could get away without changing any of that.

** RE 2.0 TSI - When I first started looking around for an engine, I was looking for ex GTI engines. When I finally found one, I asked several VDub experts, and they all said NUP. You need to change wiring loom, ECU, FoB etc... So I stayed away from it.

BTW my box is manual. Never liked the DSG.

Subscribed, and I cross my fingers for you .

I have got a 2010 90TSI and I really hope it wouldn't end up like yours 118TSI. Servicing my own car is a huge challenge for me right now (I just started getting into DIY car servicing).
