Hello all,
I have a 2011 Q7 3.0T Prestige that I have owned for about 3 years. It has been running flawlessly until today when I parked it, I got back in a few hours later started it up, put it in drive…doesn’t move. I tried all of the gears and I’m getting nothing. I’m thinking it’s either the TCU or the valve body. Any thoughts or suggestions? I ran the VCDS and I’m not finding anything out of the ordinary, definitely no transmission faults or codes.

There are archival threads of similar issues, including one that was posted in just the last several weeks on here.

Are there any fault codes showing up in VCDS at all? Did it rain while you were out of the car? Are any carpets wet inside the car? What's the mileage on it? Have you ever serviced the transmission fluid since buying the car?

I purchased the Q7 with 68K miles and I’m currently at 118,000 miles. I have changed the shocks, springs, brake lining, thermostat, supercharger oil, gaskets, belts, MMI updates as well as regular oil/filter changes since I purchased it, doing the work myself. The transmission oil and filter has not been changed since I owned it. I did look at the archives, which led me to check the passenger floor for dampness as well as wire separation in the harness in that area, no issues. I also reset the transmission control module. As mentioned, I found no fault codes related to the trans or engine using VCDS. It did not rain, nor was it run through a carwash prior to the issue. At 66 years of age, I’m more familiar with pre-TCU transmissions. So, I had it towed to a reputable local import shop here in Myrtle Beach yesterday, still waiting to hear back from them.

I'm having similar issues, was it the valve body?

Hope the problem was resolved.

Yes, it ended up being low on trans fluid. The shop changed the trans filter and oil, all is good now. From an owners standpoint, there is no warning light or a trans dipstick to check the fluid level, how would we know?
