2005 325i Transmission Light On
Service engine soon light and transmission indicator light on. Purchased a code reader and it indicates generic code PO 102 and says mass air flow low. It just had vanos hose and oil filter housing gasket replaced. Any and all suggestions to check would be appreciated. Vehicle has been a money pit for the last year...and life goes on...thanks a million for any help...

Your code reader probably can't read the BMW transmission specific code(s) that is causing the transmission light. The $30/$40 PA Soft tools from China can do this and much more, but there are other options too. I would first suspect an air leak past the MAF or a dirty MAF for your low air flow code.
