Hi all, I知 back on here after a hiatus. Sold my W204, got into an E90 M3, sold that got into an W211 amg with the p30 package, sold that got into an e46 M3, sold that and picked up something more practical, a W205 C300 sport pack. I値l try and make this quick, bough the car for a private party, with check engine light on. I have about a year left of CPO warranty, I stupidly read the code with a scanner and erased it, it turns out CPO covers the P052E code which implies is a faulty crankcase. My question is how long before the check engine comes back on. I might be the only guy on the planet who痴 hoping his check engine light will come on.
