we have a few cases in Finland. The injektor leaked gas into the oil and the cylinders were damaged

The owners must have ignored the rough running caused by the leaking injector & just driven on regardless
Not heard of a single case of it with the n20 here, only on the n54 engine.

Bit of an update:
Firstly, I wasn't 'running it rough' - it was running smoothly as far as I could tell, I wouldn't neglect an issue like that...
The N20 engine has a problem with the thrust bearing and it has caused this problem in other examples, It's going into a BMW specialist who said he's almost certain this would be the issue as he's seen it before in the N20 so will let you know when the final diagnosis is done. I have an independent engineer doing a report for the claim to prove that is was an issue that was developing at the time of purchase or when it was in the warranty (6 months). So far from the people I've spoken to the consensus is that the engine in this car is not reliable, apparently, the stock thrust bearing pressure is not set right and that's what's caused various problems. Either way, it's getting a full engine re-build just hope I can recoup the losses by proving this issue was developing at the time of purchase.

You don’t know that for certain mate, also just because it hasn’t been mentioned on this forum doesn’t mean it’s not an issue on the N20 engine. After all the N20 was also used for the 2 Series, 3 Series, 5 Series and X Series...
Perhaps, inspecting and or replacing injectors should come under preventative maintenance items on these.

I’m fairly certain that if an injector is leaking enough fuel to destroy the cylinder (which was the suggested fault) then the engine isn’t going to be running as smoothly as it’s supposed to?R60BBA wrote: ↑Tue Mar 19, 2019 2:56 pmYou don’t know that for certain mate, also just because it hasn’t been mentioned on this forum doesn’t mean it’s not an issue on the N20 engine.

The 20i range of z4’s has been made for long enough to tell if something’s an issue or not, I’ve never heard a single instance of injector problems on these engines, they’re different to the 35i/35is versions which are known for leaking fuel.

N20’s aren’t bad
Chains are the big problem, the odd cracked head, injector faults and HPFP probs
If you got a MY15 on car though, all the problems had been engineered out..

Nightmare!
Currently trying to install a 2.5l in its place, to get away from the fecking N20!
Not having much luck there either though... fml...
1st... E85 2.0i... stupidly sold it because I needed a "work car"
2nd... E89 SDrive 2.0... thurst bearing failure rendered the engine useless
3rd... E89 2.3i... The Doner engine for the 2nd... the transplant has begun!
