Ok. So audi recall was for airbag they also changed the inlet manifold and did a software update but as that was some months ago. They didn't say why and what it was for. Gonna try getting hold of a full vcds reader hoping that will have better chance in getting a code up than the garage.

So mechanical has been over and he is stumped battery ect is all good his advice was its software or electrical as his cpu is good but not perfect. It's recently had a software update at audi wen it went in for a recall. Could this be a problem?

I have another older 110amp battery. Would it be worth charging that and trying that in its place

So it's a 07 c6 f4 allroad auto. Was hoping that with the attempted jump like you said would at least get the instrument cluster on as it was only a 2lt car the revs were hight but carnt guarantee they were over as i was in the car 20250613_165052_1.mp4 . But it did not. Using a multi meter to test voltage at battery and in engine compartment also from battery to the engine compartment. Iv checked continuity of the earthing from battery to engine block. I checked voltage from battery to engine block and it at 12.6. I tried disconnected the battery module that didn't change anything. Car has been on charge throughout but disconnected for any test then placed bk on charge. Whilst its on charge its only reading 12.7v don't no if that's relevant but got a bigger charger coming 2mrow. I turned the radio off

Sorry. No it did not crank the engine

So took a battery reading 12.6v then 12.3 with the ignition on. Jump start from donor car did not work/change anything in the dash.

Ok so far. Iv test every fuse including both sets under the bonnet. Popped over seen garage he is of the similar opinion and said to test earthing. Iv test the earthing by jump lead from -at battery to engine block. I've tried to jump start the car the doner car wasn't very big tho. Iv ordered a large capacity jump pack and a newer charger. If that don't work I'll have to push it upto the garage. I've seen that you can manually get the car out off park. But that won't be till next week. Will keep feed upto date with progress. Thanks Grant

Do you think it could be the battery still ? The health bubble is also green.

Hi all So iv had a problem with starting the the car. Fob works to open the car the radio and internal lights come on. But wen I place the key in and turn it 1 click right there is nothing on the dash. The car clunk's and release the steering lock fine but then that's it. I carnt get the old reader to connect to check and codes. The battery is good I charged it for 24 hrs and was registered 12v. First thought was starter motor but if this was the case wouldn't the car still turn on and then not start. Any help would be appreciated. Thanks Grant

Hi. So pulled the fuse for the headlight washer and so far so good. But as it is a mot requirement will have to change the coupling behind the bumper at some point. 30a passenger side. window washer work as normal.

Cheers guys.

Hi all. Question ?. Headlight washer pipe has a leak at the the junction. It's a bumper off job to get to the coupling. If I pull the fuse for the Headlight washer pump will it continue to leak or am I gonna have to change the coupling. Thanks Grant.

Hi. Thought I'd put an update incase anyone has this problem in the future. It is a absolute nightmare but it works so just bare with it. So come up from the bottom with a rod with a 90° on either end 30mm on one end and 100mm or more on the other this is just a handle to twist the bar. A inspection camera with a light is a must or your just fishing in the dark. I taped my to a extend magnet. So I could get a decent view and let go. It's very fiddle and and stressful and annoying but so you want to there the bar up and using the camera get the short hook in the lower catch and twist the bar counter clock wise to release the bonnet. Took manny attempts as it pops out drop it ect it all so takes alot more pressure than I thought it would but it works so just keep on and bear with it. Hope the photos help make more sense of it all. 20231117_120645.heic 20231117_120632.heic

Hi all So I was changing the serpentine belt and managed to nock the bonnet release cable out the latch. I checked the leaver in the foot well and that's all good. The option iv come across most is to come up from under the car with a rod with a angle on and pop it in latch and twist. Has anyone come across this problem before or even tried sed method them self's any advice would be greatly appreciated. Thanks Grant.

Ok. So thought I would add to this as it stopped working again. Turns out it was the pressure switch it's self. It's a bumper off job but simple enough. The sensor was lose wen I got to it but changed it anyway as I had new one. Hope this helps.

Hi all. 2007 a6 c6 3lt allroad. Any advice as I'm all out of options. It's hard to describe the car idles higher than usual and there is a distinct slow pick up and less torque. Turbo don't kick in till 3rpm as wen before it would be 2 and a hell of alot more powerful. Over taking at speed is a real problem. If you had never driven the car you probably wouldnt notice. So i had a p200 fault code. So i changed the throttle body and cleaned the turbo New air filter fuel filter. There is no longer any fault code but the car is still the same. any advice on possible cause would be much appreciated.

Finally got my lazy arce up a gased the air con and all is sorted. I would have thought the blowers would have still worked with out but not on this occasion. So I'd check gas pressure as a pre test before changing parts.

Update. Changed the control unit still nothing got a multi meter in the back of the plug and its getting 13v so next stop gassing the air con.

Wen I took it off to change the fan it looked brand new (bosh) there was barely any soot on the metal. But that was my next point off call. Long shot but would the air-con be a issue ie if it was empty maby.

Hi. Iv checked all fuses. Should mention iv got the diesel which has no relay just manny fuses apparently that is.

Yer. Iv got no fault codes. Will try both options and update after. Thanks Grant.

Hi all Having a nightmare with the air con system. I have nothing lights up can change settings ect but no air coming the the vents at all. The econ light is permanently on. Iv checked the fuses but carnt find/identifie the relay. Iv just swapped the motor it's self for a new one and still nothing. Any tips or pointers would be much appreciated. Thanks Grant.

Thanks guys

Hi all A6 (c6) 3lt allroad. Hi has anyone upgraded or no of any possible upgrades to the air intake system. There seems to be a lot of plastic taking up a lot of room. Or is it just best leave it be. Thanks Grant.
