Over $3600 in repairs needed due to power train control module which is a major brain to the vehicle. I just bought this q7 in September it was 4 years old. Anyone else dealing with this? 38,000 miles seems too new to have so many issues.

 

Audi dealers tend to recommend you replace entire systems/modules rather than troubleshooting the basics to resolve the issue. They will take advantage of you, as you are no doubt aware of after paying their diagnostic fee of 1 hour of labor rate (twice the rate most independent/honest shops charge). If you don't have an extended warranty, it's best to steer clear of the dealership unless you are buying a battery for carryout, or need some touch-up paint.

Since yours is a 4M chassis car (meaning built after 2016), you actually need to be posting in the Q7 Mark II sub-forum (2016 - ?), which is where you will find support for your chassis model. It's listed just beneath this Q7 sub-forum, when you are looking at the Q7 sub-forum options. The Mark II was a clean-sheet redesign, so there's not much crossover between the old and new generations of the Q7. If you don't DIY, then you need to locate a good german car mechanic/indie shop to diagnose the car. You'd be surprised what you can actually DIY on the Q7 with the Ross-Tech VCDS diagnostic scantool...truly it is a lifesaver, and quite a good investment in your own sanity. Oh yes, 'normal' OBD2 scantools, like most auto-parts corner stores would use, are not compatible with the Q7 or similar VW products...see VCDS if you want to save money on repairs.

Fair warning though; Consumer Reports lists the 2017 and 2021 Q7 models in their 'Used Cars to Avoid' category...seriously, look it up.

Good luck!
