Just to share, I have been using Audi CVT for a couple of cars with the same fear. recently my friend's car ran into similar problem, Its 2005 model A4 B6, happens to all Audi CVT from 2002-2006 I think. First as foremost depends on your luck the TCU will goes, symptom Flashing PRNDS on the instrument panel, sometimes gear dont shift and cant move car. This is a US$2k fix, the gearbox need to be flushed to change the TCU in the gearbox, it will sure need one time change between 30k to 50k miles, depends how you drive your car.I have heard that the CVT in the Audi A4 has problems. I've heard it tends to burn out early. Does anyone know this is a known issue, and about how many miles they actually last?
I too have own a few CVT Audi's, and have worries on the troubles, people are posting. Had taken care of the cvt well by changing the Oil every 20,000 miles, expensive oil(have not found alternative). Even with such care the TCU transmission control unit still need to be changed sometimes depend on your luck 50,000k miles or 80,000km.So, just to give you all an update...after posting this message, I did quite a bit of research and found that MANY people have experienced problems with the CVT transmission on the Audi. I was prepared then, when the Audi service dept. called to say that my "friction plates" were gone, and I was faced with a repair for $2450, and that this was not covered under the warranty. (Just as an aside, I found that many other car companies warrant the transmission to 100K miles.) When I confronted them with the fact that this is a known problem to Audi, and what did they intend to do about it, the service manager called offering to use his "good will funds" to cover the part ($800), leaving me with $1650 out of my pocket. I said that I appreciated his offer, but that I would call Audi directly. After speaking with the Audi rep, the Audi service dept. called back to say that they (collectively - the local Audi service dept. and Audi corporate) would cover $1450, leaving me with $1000. I also voiced concern that I would be faced with another part of the transmission failing in a few months. They say that they will warrant this part for 12 mos./12K miles, but that any other problem would not be covered. For now, I've decided to leave it at this...but to be sure, I will pursue this in the event that "other" parts of my transmission fail in the near future. I suspect that this is Audi's response to the crisis - rather than tell me the entire transmission needs to be replaced (to the tune of $6-8K), they have decided to "minimize" the impact by only fixing pieces and parts. I read about one person who apparently successfully sued Audi under lemon laws related to this problem. I suspect that will not be out of the question for me if this continues to be a problem. Of course, I could just go ahead and sell the car once this repair is done...but I love my cabriolet...and it's paid for. Anyway, stay tuned for more as this saga continues.
