W2FINEST Posted January 18 Posted January 18 Hello there so I have an 07 Q7 V6 that won’t start. The doors unlock and lock with key the dome lights work & so do the hazards etc. when I open my door the only thing that pops up on the cluster is the miles but when I put my key in the ignition nothing my happens when usually the steering wheel will unlock and the dash will turn on but it doesn’t do anything. I just replaced the battery in both the car & key fob & still nothing. I checked all the fuses and I also replaced the relay next to the battery under the driver seat. I tried to connect an OBD reader to it to find out what is wrong but even that won’t work I have no clue what to do nor do I know what is wrong. If someone could PLEASE help me I would really appreciate it!
Steve Q Posted January 18 Posted January 18 Welcome to the forum you'll find the members on here are a friendly and helpful bunch. Was the battery coded to the car when it was fitted? Well done for trying to plug it in. You'll definitely need a diagnostic check to see if any fault codes flag up? Have you got home start with breakdown cover? Also I've hidden your other thread as it's a duplicate. Cheers Steve
W2FINEST Posted January 18 Author Posted January 18 No the battery wasn’t coded to the car and when I try to use an OBD Reader it won’t work because there’s no power

Steve Q Posted January 18 Posted January 18 This video shows you how to code it: Might be worth you getting an auto electrician to come and code it.
W2FINEST Posted January 18 Author Posted January 18 (edited) Could I code it myself ? Edited January 18 by W2FINEST
W2FINEST Posted January 18 Author Posted January 18 And my car wouldn’t start or get any power even before I changed my battery
Steve Q Posted January 18 Posted January 18 The video on my previous reply might help. Also the Ross tech site has lots of useful information: http://wiki.ross-tech.com/wiki/index.php/Audi_Q7_(4L) Specific details on their battery section: http://wiki.ross-tech.com/wiki/index.php/Battery_Replacement I believe the obd port is fused so might be worth checking the fuse. This video might help with connecting obd11 to it: https://youtu.be/QH283J1Wkno?si=-ByYuL3bZ8fBi2DB
Steve Q Posted January 18 Posted January 18 Think the obd fuse is in the fuse box at the left end of dash and is in the middle row of fuses, brown holder and is fuse location #12
W2FINEST Posted January 19 Author Posted January 19 So the battery is programmed and still nothing what I think it might be is the steering wheel lock thingy so I ordered this repair kit hoping it is this if not then idk what the heck it is
Steve Q Posted January 19 Posted January 19 Yep could be. Glad battery is programmed. Did you check the obd fuse?
