Hey!
I have recently bought a 1997 Audi A4B5 with an AFN engine. When I bought the car, the turbo was not working, and it was getting limp-mode fairly often so I tried everything I could find on this forum, and finally traced it back to a broken vacuum line. After I replaced it, the turbo started working again and it felt like I was in an other car, the car performed very well. I looked at VAG-COM to check the boost pressure and it seemed health, the actual value seemed to follow the required value, maxing out at approximately 2000 mBar (so the actual boost maximum was roughly 1 bar plus the atmospheric pressure), I suspect that is the default on engines. However, the engine stopped on the way home and could not be started again. It was recently taken apart and we could see that cylinder 2 has melted. I'm getting the engine replaced with another AFN, but I'm curious what may have I done wrong and what to look out for when the new engine is installed so this does not happen again. I'm perfectly fine with the stock performance of the engine, currently not looking to do any mods to it, be it software or hardware.
Any help is appreciated! Thank you.
