I am in the process of purchasing a Q7 S-line+. I have had the vehicle for a couple of weeks on loan and there are a few things troubling me.
 

1. The stereo system is standard non bose/B&O. Is it possible to add a subwoofer and how would this be achieved. I have read as many articles as I can, most refer to swapping out the Bose sub and using the wiring. This is not an option for me. 
 

2. On two occasions I have had the TPMS warning. Each time I have checked the tyres, they were okay and when restarting the car the message has gone! Is this normal? 
 

3. The car starts fine but have heard the starter motor sound laboured for a split Second almost like a flat battery but then kicks in to life. It is a split second but wondered if this is a tell tail sign of starter on its way out. 
 

4. I can’t see what track is up next when scrolling the wheel under the mode button while listening to To my phone via Bluetooth, is this normal?

 

other than the above, I’m very pleased with the car🤣

Any help would

be appreciated and hopefully

set my mind at ease before I part with my money. 
 

Cheers, Scott

Welcome to the forum you'll find the members on here are a friendly and helpful bunch 🙂 

Might be worth getting the battery checked rather than assuming the starter is on its way out. 

Yep a sub can be added any auto electrician could do this for you. 

Thanks for the reply. I’ve also seen a number of posts recommending a second earth lead. It’s in the garage at the moment and have passed on the info. 👍🏻

Nice one ☺️
