The wife has just picked up a Mk2 1.2 TSI, replacing her old Mk1 1.4 16v. That itself replaced a 1.4 8v. My lad had a dodgy vRS at one point too. So, I've replaced a few window regulators, a couple of power steering pumps, steering sensor and some sundry items. The 16v failed the MoT on emissions and some suspension stuff. The emissions didn't chuck any engine lights up so could be a ballache to resolve, so it is scrappy-bound. Is there anything worth stripping off the old one to keep in the spares box?

Emissions on the 1.4 16V might be valve stem seals if it smokes when you blip the throttle and if it uses oil, however it's more likely to need a new pre-cat lambda probe and a good run out. Suspension stuff is easy and cheap to fix.

 

The car is well worth saving, fixed and with a fresh MOT it's worth a grand all day long and it'll be more reliable than the 1.2 TSI to boot, newer ain't better I'm afraid.

I have a spare lambda sensor from the earlier 16v, which I think fits. It doesn't really smoke or burn oil but smells very rich - has for the 3 or so years we've had it. A failed sensor would surely have thrown up a light and code. Of course the only way I can confirm a fix is to go through a retest, which means doing the rest, and I really can't face it. It's still a good car and would be a nice starter car car for someone. Having been car shopping recently I'm astounded by how badly looked after some cars are and how shabby the interiors are.

Door bellows wiring seems to be one of the most conspicuous(ly common) mk2 failure points. Definitely worth inspecting for any door electrics faults.

There's some valve in the PCV system on the 1.2 TSI that's made of something too fragile, but pretty well regarded engine generally. 🙂

 

What year is the 16v?

2004, 54 plate.

 

I was wondering whether to pull out something like the steering sensor, PAS, lambda, window motors? Any handy parts references to check out?

PAS stuff may be interchangeable, doubt the other bits are.
