audi a6 c6 estate Not starting

[Mansour]

Hello I’ve had this audi a6 for a while it was going good but in the last months I’ve ran into som problems, the car randomly when I want to start it, every light on the dashboard comes on it gives crank but no start, sometimes I have to jumpstart it, I saw someone with the same problem on here. I’ve been told it’s a battery problem but I changed the battery about 2 weeks ago, other say relay, dynamo or fuse box but I don’t know

Welcome,

The new battery may (just may ) need coding to the car, but 2007 is on the borderline for needing that done. 
Have you checked the alternator output, and have all battery and starter motor connections been checked? 
Kind regards,

Gareth.

I coded the battery still the same problem, I think it’s the dynamo

A3s of that era were prone to failure of the instrument cluster which gave similar symptoms to your car, so it is possible your A6 suffers in the same way. Audi will want a small fortune for a new cluster in England or a large fortune in Norway. The clusters can be repaired at much lower cost if you can find a suitable company. If you can not find a local company it would be worth investigating if ECU Testing, a company we often recommend here, would do it.

What is the solution mate because at this moment I’m sitting in my car and it’s not starting because of this problem

Sorry if I was unclear. If the instrument panel or cluster is faulty, which you can only discover by having it tested, it must be repaired or replaced.
