7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

Lambda

Hello again all! Ive recently got a check engine light. The codes stored in the dme are for both lambda sensors before cat. When i delete them i need to drive a few hours to get the codes back. Could there be anything else that are giving me the codes, or is there for sure the lambda sensors?
Thanks
