2010 Audi Q5 Electrical System

Water leaked into the rear battery compartment and into the trunk passenger side fuse bay. No apparent reason for leak. All windows, doors, sunroof and truck lid were closed. Flooding shorted control modules (parking aid controller, CAN buss and etc) flooding also took out the battery causing car to stall on highway. Water gets in after rainy days. Suspected malfunction of sunroof drain, but not certain. Shorting of electrical components verified by mechanic. Multiple parts needed replacement. No warning lamps prior to events. Available for inspection upon request.

LEFT HEADLIGHT DIP LIGHT COMES ON WHEN I AM DRIVING AND HIT A HIGHWAY BUMP AND THEN THE LEFT HEADLIGHT FAILS. WHEN I SHUT THE CAR OFF AND THEN TURN THE CAR BACK ON THE LIGHT WORKS AND THE DIP WARNING LIGHT GOES OFF.

2010 AUDI Q5 WITH CAMSHAFT SENSOR FAILURE RESULTING IN THE EPC SYSTEM ENGAGING WHICH PUTS THE VEHICLE IN SAFE-MODE. FIRST ATTEMPT AT REPAIR FIXED NOTHING. AUDI DID NOT ALLOW THE DEALER TO REPLACE THE FAILED SENSOR ON THE FIRST REPAIR VISIT, RATHER THEY INSTEAD SWAP LIKE-SENSORS AROUND, THE SEEMING EQUIVALENT OF RE-ARRANGING A BURNED OUT LIGHT BULB. IT IS QUITE FRIGHTENING WHEN THE EPC SYSTEM DEPLOYS, AND A MORE PROACTIVE APPROACH FROM AUDI ON DEALING WITH THIS FAIRLY COMMON PROBLEM SHOULD BE MANDATED. *TR
