2007 Audi Q7 3.6L (BHK) 6-spd (09D)
No Start
No Terminal 15
No Ignition

Hi Group.

I'm getting hammered this week! Had this Q7 in the shop a week ago and repaired a defective Fuel Pump at the time also found an open E-Box L.F. repaired some wires in there that were damaged from corrosion (Water Ingress).

A week later it returns for intermittent hard start. Got into it started it about 20x and walked away, tried to pull it inside at the end of the day and it's DEAD! Jumper pack, Nothing! No communication via scanner! 

Never worked on a similar problem on VAG models using a Start/Access module.

Can anyone enlighten me as to how the Start/Access Module can be tested or temporarily bridged? I'm getting nothing as far as any kind of switching from the Ignition!! No circuit 15, nothing!!! I could really need some HELP on this one as I have 4 other nightmares sitting here kicking my A$$.

Thanks, Dan the German Diagman

- manually ID the vehicle with a scan tool. Turn on the 4-way flashers and pump the brakes every 2 seconds. While doing that, run a full scan. See what is awake. - Does the steering wheel unlock? - Does anything work in the vehicle? - Is the battery igniter blown?

Hi Chris. Thanks for your advise. Vehicle is up and running!!! After spending about 6 hours on it over the last three days and now being very relieved but also ready to take the heat on this one from the group or at least offer a very GOOD laugh for you ALL! What an Idiot I was on this one! After posting the request I moved on to another car that's been sitting and waiting since Friday…

Nice to know it happens to others. Gave out the wrong VW key to a customer who used their spare to drive away. Customer from out of town came late to pick up and car won't go. Ultimately after several tries to contact customer one, I drove Customer two, a hundred miles and back to get his spare key. Funny now but missed a ski weekend over it. Family wasn't happy.

Not the first time that's been done and it wont be the last. :) I bet you will be checking the keys of other shop cars if you have that problem again!

Doesn't everyone tag customer's keys?

Wrong key was used!!! Vehicle uses a flip type metal key that slides into the ignition & turns but I assume it doesn't have anything inside the cylinder other than a electronic ID to allow for start authorization and of course there isn't a message indicating that the Wrong key is being used. Thanks, Dan
