Recently the car has been giving the impression of a flat battery when trying to start. It would turnover a couple of times but very very slowly. Turning the ignition off and then on again and the car would turn over slowly and then speed up and start but this may take a few attempts. It gave all the impressions of a poor starter motor. But having fitted one on a previous Q7 I know this is a 4 hour job and even with a decent discount is still over £200 for the unit. So decided to ring a local auto electrician that could hopefully diagnose exactly the part that needed replacing. (Vagcom showed nothing amiss by the way). He turned up and checked the car over and said that the cars alternator was charging the battery at around 13.6v. This is a indication of a poor earth and fitted another earth cable from the earth point under the bonnet used for jump starting to the engine manifold. Said he’s fitted loads as it’s a well known problem within VAG that the earths corrode over time and need cleaning. The car now charges at just over 14v and starts better than it ever did less than 2 seconds from turning the key. Turns over faster than my mates 2011 and 2014 Q7’s. Cost £10 for the earth cable and £40 for callout Including 1 hours labour. Hope this is helpful to anybody with a similar problem.

Are those 22” Justin?

I think it’s on the passenger side dash board. There is 3 rows of fuses. It’s the top row 5th from the right and will be a 20 amp fuse.

If you haven’t sorted the battery drain issue out yet then I would try pulling the fuse out for the aux heater then leaving it over night as a faulty unit is a common cause of battery drain. Also the new battery should really be coded in using vcds so the battery control module can regulate power so You can’t drain the battery say with the radio when the car isn’t running to enable it to always start. But I doubt this would cause the battery to drain over night. There is a common thing with starter motors (“lazy starter”) too where they crank slow and look like the battery is flat my old Q7 had it and my current Q7 is now suffering from it. It requires changing but this is a 4 hour job as it requires an engine mounting and the alternator moving. Europarts do a Bosch unit which is about £300 but you get £70 back by giving them the old unit. Under the bonnet at the back is a positive connector used for jump starting. If you have a multi meter you could measure the battery voltage there and fault find

Is the tailgate closing fully or does it End up being left slightly open. Can you post some pictures. My last q7 had a problem when I bought it where the tailgate didn’t close fully and as it was pulling it down you had to manually give it a push when it got near to get it fully closed. Turned out to be a small spring that had snapped on the latch. Just remade a hook on it using to snips and hooked it back on. Took ten mins. Somebody put a post on here about it. Try looking through the earlier posts.

My rear panel won't open at all and hasn't done since I've owned it. Apparently they seize up. Try closing the rear sun visor and then closing as the sun visor clip can go back too far when open and put too much resistance on the sun roof so won't close. Failing that there is a panel on the passenger side of the dash board when the door is open that comes off and exposes some fuses but on the back of that panel there is a special shaped Allen key. Pull the interior light down behind the sunroof to expose the motor. There is a really obvious hole the key goes in where you can manually wind the roof back in. Hope this helps Sorry can't post a picture it says max total size 0.24mb 🤷🏻‍♂️

Yep the car has had some paint on the front bumper and bonnet which looks like it was probably stone chip repair. But as this wasn't done by Audi who knows what coatings have been applied to the car at the same time so I'm sorry sir but the warrenty won't be applicable in this instance. 😂 Was worth a try and the guy was pleasant and offered me a go in a SQ7 when I have more time. So when the kids are back at school I'll take the wife over and him what it can do 👍🏻

Hi I've notice a couple of imperfections on my Q7's bodywork most noticeable is some small rust bubbling on the drivers side rear door handle and was going to get them sorted by a garage who told me that audi's have a 12 year corrosion warrenty and to ring them to get it inspected. Has anybody tried to get anything like this sorted by them or am I just wasting my time as they will just fob me off with excuses that I can't argue with?

Finally got around to sorting it out. Borrowed a mates borascope to check the wiring and if the drainage for the rear sunroof was leaking onto the connectors. All fine so bought a gps antenna with the correct connection off eBay for £3.50 and tested it. Now works fine. Slackened off the rear trim panel and fished the wire down so the small square antenna sticks to the rear window. Job done

My Q7 was intermittently taking a while to start (10 seconds then a puff of white smoke when started) diagnostics showed the number six glow plug was the problem. Only £17 from euro parts so put a full set in and has been fine since. Was told that because it didn't fire straight away that unburnt fuel was getting to the lambda sensor and so the ecu was backing the fuel off hence why it would just turn over and over.

I bought a disc and had the same problem. It's locked at the factory and have been told that when they arrive at the dealer they should unlock it there but not all did. You need vagcom /vcds to unlock. It's very simple and takes 5 minutes to do as it just involves changing a 0 to a 1 or vice versa. I'd try ringing your local Audi dealer and tell them that you have spoken to Audi U.K. Who have told you that it should of been unlocked when new and said to ring your Audi dealer and ask them to do it. If they want to charge you then any local independent with vcds can do it for less

Yeah checked wiring etc. Passenger one works fine, all fuses fine. Does the seat 💺 need to come out or can it be done in the car. I have put dvds in the headrests and don't fancy removing to and the wiring if I don't have too. Cheers

Hi has anyone ever replaced the heated seat element a leather drivers seat. Does it involve cutting the stitching or is it a case of dismantling the seat. Cheers

Don't have a dash cam but believe it's not picking satellites up. Going to check the connections but have looked at the antena on eBay and the wires are very short so don't go to the drive directly. I have removed the interior light underneath the fin and followed the cables but the connections are under the head liner so need to drop it to investigate further. My car has a panaramic sunroof and have been told the drain pipes can leak so will check with a borascope for signs of water. I put a new map disc in and updated the software when I got the car but I'm unsure how they managed to get the nav to know where it was when I collected it from them. I want to put it back on them to sort but the quality of some of the work they have done to it isn't the best and I don't want a "bodge" fix.

Had my car back to the garage I bought it from to sort the sat nav out under warranty. They had the car for a few weeks to sort a few other things at the same time. Picked the car up Tuesday and they say have replaced a part that cost £1100 and the sat nav works fine now. Drove home and noticed the sat nav screen showed me driving in the opposite direction and now that I'm home shows my current position as being 60 miles away from where I am. Does anybody know if they could of just connected some plugs in wrong or something simple like that. I can take it back to them but it's not local to me and can't take it to them for 3 weeks. My mates with Q7's don't know as they have never had a problem with their sat nav and can't get a wiring diagram for it anywhere

What does vcds - options - test say. You can ring Rosstec for support who will talk you through some things to see why it's not talking but to be honest I'd probably ring Audi and pay £80 or something to get them to do it on there computer if it's gone on this long. I've only seen something like the problem your having when my mate bought a Mickey Mouse lead from eBay when his original one broke

Is it a genuine cable you are using to program. If you do vcds options test what does it say.

Hi what are the levels for all four channels and what are the stored values for all four channels? I think if the stored value for example is 495 and the actual value is 410 then the ecu won't allow such a dramatic change and so you will need to set it to within 20 of the stored value until you can get to where it is.

Is it Left Hand Drive? Is just one corner down or both on that side. What is the value you are trying to enter? Is the mmi greyed out on the suspension settings? What parts have you changed on the car to get to this stage?

http://www.ross-tech.com/vag-com/cars/levelcontrol.html This might help 👍🏻

Channel 4 is the rear right I think and 5 is just to confirm the values so probably will say error if there isn't any value in 4. Have you entered anything for 1,2,3? What value are you entering in channel 4. Is any of the suspension lower than the rest. I think the test conditions are that the engine has to be running and all the doors are closed

Sounds like a valve stuck open. If the bag had such a big leak that it goes down straight away when the pump stops then I doubt it would lift it up in the first place. The over temp fault is just because the pump keeps kicking in. Unless it's really noisy it should be fine. There is a valve block just behind the pump that might be stuck but check the individual valve on the strut first with soapy water to see where the air is escaping. What have you changed to get vagcom to say that. Have you changed the bag and now it's stuck down on the corner and won't raise the car at all? If so jack the car up on that wheel to take some weight off and see if it will raise it up.

I can't open it either for some reason. It's just a video from my iphone showing the bubbles coming from the top of the strut. Have you tried putting soapy water on to see where the leak is

Found a video I took when mine was leaking IMG_6176.MOV
