Open the full vehicle complaint log (all categories)I have seen at least three other complaints with NHTSA on this same item all with different headings. Check engine light comes on at high speeds while highway driving. Pull Engine code and comes back as P2753 - Valve for transmission fluid cooler circuit open. Had to replace coolant control valve for transmission as coolant was leaking into solenoid. Many other reports of this same problem on NHTSA already and mechanic says it is known issue with Audi.
VEHICLE STALLED WHILE DRIVING. UPON INSPECTION BY THE DEALERSHIP, I WAS INFORMED THAT A COOLANT VALVE CONNECTED TO THE TRANSMISSION CONTROL MODULE HAD FAILED. THIS RESULTED IN COOLANT LEAKING INTO THE MODULE AND THEREBY DAMAGING IT. THIS IS A KNOWN DEFECT IN A SIMILAR VEHICLE OF THE SAME YEAR.
CHECK ENGINE LIGHT CAME ON SO I TOOK IT TO THE DEALERSHIP. DEALERSHIP TOLD ME THAT THE "COOLANT VALVE LEAKED INTO THE WIRING HARNESS AND SHORTED THE ENGINE CONTROL MODULE. MAY HAVE CAUSE AN UNEXPECTED STALL OF THE VEHICLE."
