check engine/emissions light - can't diagnose
my 550i CEL light came on couple weeks ago, went away, came back on..
its not a loose gas cap causing this went to the dealer, they found 3 stored faults for "bank 2, before catalytic converter- performed O2 sensor test- sensor failed- removed and replaced- let car sit overnight- did test drive" - car re-delivered to me light came back on before i arrived at my office - about 8 miles back at dealer next day- replaced fuel line, why i do not know / nor did my SA the tech determined this to be appropriate - this did not correct issue, light still on this has now been escalated to the "dedicated diagnostics team" described to me as the SWAT team of crack BMW technicians who get the issues repairs that defy the normal approach. hope these dudes diagnose and fix this quickly anyone run into this issue?
