Driving x6 50i 2008, check engine sign appears frequently reffering to leak detection pump error. It has been the third time service guys replace it, error keeps appearing again and again and again. It runs ok for couple of days and then check engine appears usually when the car was idle for a day or so. There were no mechanical damages to the tank or car whatsoever. Thought it might be from increased battery discharge - charged the battery same result. Maybe low fuel quality? What could it be anyway? Please help :dunno:

low fuel quality will cause this problem come and come again,, In china as well, the same problem as you had. Due to the fuel quality and bad design of HPFP.

Just been offered to reprogramme the car to European version of software. They promissed this mistake would never show up again due to different requirements for related problems in Us and Europe. True or False?
