1. Filed Nov 19, 2025Failure Nov 19, 2025Redwood City, CAExterior lighting

   When the turn signal is activated to go RIGHT, the turn indicator flashes LEFT (both the arrow on the instrument panel and the exterior lights). Since the driver is not consciously looking at the dash, this causes an unexpected lane change and dangerous (and illegal) lane change. There are no warning lights that there is an error/problem. This is an intermittent but frequent problem and replicable. I have not taken the issue to the dealer but research suggests that the turn signal stalk must be replaced. Searching online, I see that other Audi A6, for various years, have this problem. I also recently learned that Hyundai vehicles were recalled for this same issue. Hopefully you can look into it to see. Thank you.

   Steering Rack Assist has a recall for my car because my steering locked up. Audi replaced the recall part two times. the first didnt work after the second time it works but now they cant reset the check engine lights, TPMS, Steering Fault do not drive it says, ECS Fualt, Stability Fault, Child Safety Lock Fault etc. Dealer told they did everything they could even flew in an Audi Engineer still cant reset anything and that they exceeded the cars value in man hours to figure out what is the issue. Now they tell me the car is drivable but my question is, is it safe for me to accept it like that and risk something happening while driving and the steering locking up or any other problems that may arise but I wouldn"t know because of the other alarms may override the current alarm that may pop up. My insurance said they wouldnt accept the car back in that condition because its a recall issue related and that Audi needs to address this but in just getting the run around. My car has been at the dealer for about 6 months trying to figure it out. Now they tell me "You brought your car because steering was locked up wasnt able to drive and now the car is drivable and the only thing we cant clear are the alarms that i mentioned above but it is drivable its just like an oil change alarm that you do the oil change but we just cant reset it so its kinda the same thing" they told me that and i was like okay. No is not the same i said, my question is is this even safe to accept and risk something happen and get into an accident because of the steering lock up. Now they wont even take my wife audi because has the same recall that needs to be replaced. the only way they replace it is till it happens. So they waiting for my wifes car to lock up while driving and not have control of car and crash especially if my kids are with her because she takes them to school. What do i do please help? I also requested the total estimate to see how much I owe and they will not send it to me.

    I OWN A 2013 AUDI A6 AROUND 77K MILES. I GOT THE CEL AND BROUGHT IT TO THE DEALER. THERE IS AN INTERNAL TRANSMISSION COOLANT VALUE THAT IS PART OF THE COOLING SYSTEM AND OBVIOUSLY, THAT COMPONENT ALSO HELPS KEEP THE TRANSMISSION TEMPERATURE IN CHECK. THE ISSUE WITH THIS DEFECTIVE PART IS THE VALVE MALFUNCTIONS CAUSING COOLANT TO PENETRATE THE TRANSMISSION CONTROL MODULE AND FROM THERE INTO THE WIRING HARNESS. WHEN THIS HAPPENS, IT IS A CATASTROPHIC MALFUNCTION OF THOSE COMPONENTS AND A POTENTIAL FIRE HAZARD. WATER AND ELECTRICAL DO NOT MIX WELL.

    IN LATE DECEMBER 2017 OUT OF NOWHERE, MY CAR BEGAN TO DISPLAY THE WARNING, 'TURN OFF ENGINE AND CHECK COOLANT LEVEL' (PHOTO ATTACHED) ; THIS WAS VERY ALARMING AS I TAKE VERY GOOD CARE OF MY CAR AND HAVE HAD ALL OF THE REQUIRED MAINTENANCE DONE AT THE DEALERSHIP. I IMMEDIATELY CALLED AND HAD AN APPOINTMENT SCHEDULED AT THE DEALER. JUST A FEW DAYS LATER ON JANUARY 5, 2018 I TOOK MY CAR IN FOR SERVICE AND WAS TOLD THAT THE WATER/COOLANT PUMP NEEDED TO BE REPLACED (ATTACHED). UNFORTUNATELY, I FELT THAT THE COST WAS TOO MUCH AT THE DEALER AND I TOOK MY CAR TO A REPUTABLE MECHANIC IN THE AREA WHO REPLACED THE WATER/COOLANT PUMP. TO MY SURPRISE IN SEPTEMBER 2018, AUDI ANNOUNCED A RECALL FOR THE WATER/COOLANT PUMP. TO MY UNDERSTANDING, THIS MEANS THAT THEY ARE LIABLE FOR ANY DAMAGED PUMP. WITH THAT BEING SAID, I WOULD ASSUME THAT ANY ISSUES RELATED TO THE PUMP SHOULD ALSO BE COVERED UNDER THAT RECALL. AS NOTED ON MY SERVICE MEMO FROM THE AUDI DEALERSHIP WHEN I HAD MY CAR INSPECTED FOR THE WARNING 'IF NOT REPLACED, THE ENGINE'S COOLING SYSTEM WILL NOT BE OPERATING EFFICIENTLY AND AT THE PROPER TEMPERATURE RESULTING IN CATASTROPHIC ENGINE DAMAGE.' IN FEBRUARY 2018, A LITTLE OVER A MONTH AFTER HAVING MY CAR'S WATER/COOLANT PUMP REPAIRED, THE CAR STARTED TO IDLE WHEN I TRIED TO PULL OUT OF MY DRIVE WAY. NOT EVEN A BLOCK AWAY AND THE CHECK ENGINE LIGHT FLASHED ON AND OFF AND THE CAR CUT OFF WHILE DRIVING AND STOPPED IN THE MIDDLE OF THE STREET. I WAS SO SCARED, BUT RELIEVED THAT I WAS NOT HIT BY ANOTHER CAR. I WAITED A FEW MINUTES AND WAS ABLE TO GET IT BACK TO MY HOME WHERE I IMMEDIATELY HAD IT TOWED TO MY MECHANIC WHO TOLD ME I NEEDED TO REPLACE THE ENGINE. I DIDN'T HAVE HIM DO THE REPAIRS, BUT I THEN HAD IT TOWED TO THE AUDI DEALER WHO TOLD ME THE SAME THING, TO REPLACE THE ENGINE.
