Hi, can anyone provide some guidance with the following issue? My 2005 E90 320i had the half engine light come on, seemed quite sluggish, when I pulled up, stopped and tried to run it again it was in limp mode and wouldn't rev past 4000RPM or go over ~30kmh. I managed the pull the following codes: A26F - I understand this to mean Min lift exceeded by valvetronic system. P1062 - Valvetronic Limp mode. I deleted the codes with OBD sensor and it did not return but I think there is something wrong with it, when I open the oil cap when running instead of getting a sucking sound like I used to get I now hear a drumming sound with puffs of positive pressure which concerns me. Background, car has done 120,000km. I re-did the seals on the vacuum pump and rocker cover gasket at 90,000km as it was leaking (typical I believe). It began leaking again at about 105,000km. It is leaking oil from the VANOS solenoids, could this oil have shorted the vanos system? Even if the vacuum pump had failed completely would I actually get a positive puff out the oil cap?? Or is this something else entirely? I would REALLY appreciate any help with this as I'm very worried about it. I'm a first time poster so if I missed any important details or this is in the wrong place I apologize. Cheers Richard
