Audi A6 Quattro Check Engine Light and/or Engine Overheating Due to Failed Thermostat
overheating and drive bad sometime white smoke come from the tail pipe. - tbaby43
Thermostat is faulty. Was replaced three years ago as part of a factory recall. Problem has resurfaced. Cost is ~ $1,000 because thermostat is located beneath the supercharger and replacement is "labor intensive." - Visitor
While driving the thermostat sign appeared on my dashboard and smoke started to be seen on my hood. Had to park and have it towed to the nearest Audi dealer. The following day the dealer replaced a failing thermostat free of charge covered by my warranty. Just a hassle getting the fixed in between work. - Visitor
