Having a problem with my 3.0tdi audi q7 2008, went out in it and after 30 seconds it cut out, managed to get it home since then it hasn't started. I've had it at several garages and they have no idea what the problem is, there is a Terminal 30 low pressure fault and steering angle sensor fault. The car goes to start but just won't crank, I've had everything mechanical checked like injectors etc and they are all fine. I'm just wondering if anyone has had an issue like this and what it actually was?
Thanks

Hello Luke,

Thanks for being in touch with the forum, and sorry to hear of your issue.

When you say ..’ had it at several garages…’ - would any of these be diesel specialists, as opposed to ‘garages’ ? 
Kind regards,

Gareth. 

It's been at my local garage and then I was told about a diesel specialists from an auto electrician but he didn't have any idea

Thanks 

Luke

Thanks Luke,

Not sure if you mean the auto electrician didn’t have any idea, or if the diesel specialist they recommended, didn’t have any idea?? 
For recommended diesel specialists in your area :- enquiring at your local taxi rank usually comes up with good  recommendations, since these boys depend upon good service for their living.

Kind regards, 

Gareth.

Does it turn over and not start or not even turn over?
