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.

Need Master BMW Tech Advice: 9C78 Wiper Console Heater


9C78 Wiper Console Heater ended up being a Faulty Heated Windshield.

Diagnosised by jumping the K8 Relay then tracing it to the E55 Wildshield Element which is burnt out, setting the 9C78 Fault and not allowing AC Operation.
