2003 Audi A4 3. 0 cabriolet convertible started shifting rough and hesitant and shut off, cranked back up went into limp mode and all the shifting gear lights came on r n d 2 , barely made it back home, put code reader on car had a lot of codes on it I reset codes but rnd2 lights still on , possible bad tcm?.
Transmission control module transmission slips out of drive while driving into like neutral and when I accelerate the car does not move and comes to a full stop and I have to stop and turn the car on and off till it works again.
Suddenly, while driving on freeway, went to low gear speed and not able to move car. I already change the transmission @ 42,000 miles at Audi dealership. This is Audi cvt transmission. It has very bad reliability records. You can see a lot of complaints, a especially about tcm module. Transmission repair shops just refuse to repair this type of transmission. The only choice is Audi dealership. The dealership price is about $8,500 for manufacturing rebuild transmission. However, the most important is the safety. I would not like that anyone was injured on the road because of malfunction of this transmission. It just matter of time and transmission will be broken and somebody got hurt.
2003 Audi A4 tcm failure almost led to a serious accident. Was backing out of a driveway on a semi-busy road in winter park, FL when the transmission control module gave out on my 2003 Audi A4 cvt transmission. The car lost all power and just would rev. But not move in reverse. I had to quickly throw it in drive and head into oncoming traffic until being able to get inot the proper lane. After driving home, I noticed that this is random and there is no logic to when it occurs. The problem is an intermittent electrical tcm problem in which signal 'drops' for a short period of time. I did a search online about theis issue with the 2003 cvt transmission from auid and the tcm shorting out while driving is a very common issue. I see this as a safety issue and definaltely hold the auto manufacturuer at fault. Audi has recalled these tcm's for their a6 and a8 line that year which uses many of the same components. Why has the 2003 A4 cvt not been recalled then. It has the same issues. Tcm failure and faults due to improper electrical connections and clutch pack failure becuase the transmission cannot handle the power or weight of the car. That is why from 2005 and on the cvt comes with 7 clutch plates. Bottom line is that if this issue is not addressed in the 2003 Audi A4 cvt and you do not recall this year and version tcm (and maybe even the tranny itself) people will die in accidents that were no fault of their own. I am headed to the Audi website and any others who will take my complaint about this issue. I see it up there with a stuck accelerator. If you cant control speeding up or slowing down and the problem is faulty electrical thus happening intermitently how can you stay in control of your vehicle?.
I have a 2003 Audi A4 3. 0 cabriolet with 38,000 miles on it. The gear display began to blink frequently and the manual shifting functionality would not work. Additionally, the transmission would not engage while in reverse on several occasions. The dealership informed me that the transmission control module (tcm) needed to be replaced at a cost of $2,400. After researching, I have seen many similar complaints and feel this may be due to a manufacturing defect, given low relative miles on the vehicle.
The vehicle sometimes does not go into reverse and jumps forward when applying brakes. The p r n d lights flash on the dashboard. The dealer says it needs a transmission control module (tcm).
Audi introduced the continuously variable transmission (cvt) to new automobiles about 2003. The cvt was touted as a highly reliable transmission in Audi sales brochures with less moving parts. The transmission contains a transmission control module (tcm) which fails early. I took my car in while under warranty with claims of the transmission "hopping" and Audi took no action to correct. My car now has 150,000 miles on it and the tcm has failed completely. Upon reviewing several Audi forums, I have learned that this problem is extremely common and Audi has not acknowledged the problem. Many people with similar Audi's in year and with the same transmission have experience the failure. The fix is to have new tcm's installed at a cost of approximately $2,500, which requires the removal of the transmission to replace the tcm. While I have read many narratives of Audi owners experiencing this problem, I do not know if anyone has filed a complaint regarding this issue. It would appear that appropriate testing of the module was not conducted to a satisfactory level and components were installed with flaws. My understanding from research on this topic is that the same cvt was licensed to Nissan for installation within their vehicles and the same problems are occurring. I believe this to be a condition of manufacturer recall and correction at no cost to the owner. I have also heard of the problem from local mechanics.
