2013 Audi S4

Transmission fail while driving and stationary at traffic light. Main DTC: P179F00 - Drive sensor position: malfunction Additional DTC: P179E00 - Drive sensor position: electrical malfunction ABS: 00473 Parking brake: U111300 TCM: 01315 This situation occurred 3 times in the past 3 weeks while driving or being stationary at a traffic light. Event triggers loud warning sounds, red flashing lights/icons in dashboard, total loss of power while engine still running. At this time, this problem creates highly dangerous driving conditions with random total loss of power. The situation is temporarily remedied if engine is shut off and restarted.

At times Vehicle suddenly loses power and displays “transmission malfunction:you may continue driving” but then fails to accelerate to or maintain highway speeds. Other times when vehicle is stopped in traffic the transmission delays engaging when pressing in the accelerator and thus causes an unexpected delay to movement or if on an incline will roll backwards.

My MMI 5F module went out right after an oil change service on Nov 12, 2022 I called them as soon as I got home to inform Leader automotive in Normal Il. I was told I would not be able to be seen until January 5 2023 at 1:pm. I then called back a few days later and was able to move that appointment to Dec 16 at 10:00am. I paid $179.11for them to inspect and locate the issue: according to leader automotive the 5f module is bad and needs replaced. In my print out it states it is no longer in production. This part # 8RI-035-746-C is my entire control module that controls all my safety sensors, fluid levels, tire pressure, suspension control, navigation, hands free technology etc... I contacted Audi USA via Facebook and asked why the part is no longer in production. Via Instant messenger on Dec 16 2022 I answered all their questions and was told by Audi USA they would get back to me on in 2-3 days. I have heard nothing from them. When you try and call the hold times are 3.5-5 hours. No warning signs that the unit was failing other than the radio would turn on and off. It would not stay on long enough to reset tire pressure etc... after they inspected it it no longer turns on at all. My car is a 2013 Audi S4 that has had all the required maintenance performed by Audi. It has 50K miles on it. Well taken care of. I was told by [XXX] that the part is no longer made. I could search a junk yard to find the part and they will put it in at a cost of $283.50. She also said it sucked that they no longer make the part. I asked if the entire system could be replaced I was told no as she kinda laughed at my question. I asked about the safety of my car now and again she just stated that it sucked for me.

SERIOUS STEERING ISSUE GOING ON. ENTERED HIGHWAY IN COMFORT MODE, ACCELERATED AND SWITCHED LANES TO PASSING LANE WHEN SUDDENLY THE STEERING HAD A TORMENTED MOMENT AND DECIDED TO STEER ITSELF FROM THE 12:00 O'CLOCK TO 3:00 O'CLOCK POSITION, WHILE DRIVING AT HIGHWAY SPEED. THIS IS VERY DANGEROUS AS I HAD A CAR ON THE RIGHT OF ME AND MY CAR TRIED TO DRIVE ITSELF INTO THEIR LANE. THE STEERING ALSO HAS NOTCHINESS GOING ON, AND HAS BEEN CONFIRMED BY MY LOCAL DEALERSHIP, BUT ONLY AT LOW SPEEDS. THIS ISSUE IS LIFE-THREATENING AND NEEDS TO BE ADDRESSED BY AUDI.
