I have a 2013 TDI Q7 which I love and want to keep going however recently it will randomly turn off. Typically I'm at a complete stop or a very slow "rolling stop" when out of nowhere the car turns off. I have to put the car in park and restart - which it does just fine. It doesn't do this at every stop or every "rolling stop" but here and there. Typically with weeks or months between the incidents. Even more rarely it will sputter and then if I'm able to get enough gas going it will kick back to life, if I don't catch it in time it will completely shut down. Took it to the dealer to have a full diagnostic run on it and they claim that they're not seeing any issues. Clearly there's an issue. Anyone else experience this? Or know what the cause could be?

Interested to hear if problems with the rear springs on Q7's are common? I have a 2016 3ltr S Line with a FF retractable towbar & have been doing regular monthly 6hr journeys towing one horse with the horse standing in the offside section of the box. Last week I took the car for an oil change & was shocked to be told that the offside rear coil spring had snapped. I asked to keep the spring. There is no rust evident but the cup looks extremely worn / damaged. Is this a common occurrence when towing & should the suspension have been upgraded when the towbar was fitted during the build?

I’ve not long bought an Audi Q7 2009. The yellow warning light comes in after a few mins driving. When I start it things work perfectly at all heights but then it drops into automatic and the light comes on. I think….it’s front left that’s the problem. I don’t have a diagnosis tool yet and I’m in free fall panic that I’ve bought a pup. Cars done 134k and otherwise perfect so far. Please be gentle ! thanks Dave

I have two cars – an Audi A6 C6 2005 V6 3.2L and a Q7 2007 V8 4.2L. Quite some time ago, my mechanic had replaced the battery management module in the Q7 with an additional one that I had lying around for the A6. Is the A6 module compatible for the Q7. The part number for the A6 is 4F0 915 181A/0 199 000 013 while the one originally in the Q7 was 4L0 915 181/0 199 000 017. I am asking the question about compatibility because lately I am having a problem in the Q7. Whenever I start the Q7 engine, the battery management module gets the DTCs 02254 – “Interface to Generator 004 - No Signal/Communication” and 02479 – “Partial Consumer Shut-Off Active 000”. Previously in the autumn of 2022, the Q7 had stopped twice while driving. As I could not immediately restart the car, while waiting, I had measured the battery voltage and found it to be around 11.2 volts. The DTCs would appear then. I had to wait for the voltage to rise above 12.5 volts before the car would start. I assumed therefore the battery was weak. I do not want to replace until I am sure that its not the battery management module nor the alternator. What causes this temporary loss of interface to the generator? Bad alternator? Weak battery? Connection problem between alternator and J644? Or the J644 module itself? I measured actual voltages with multimeter and they seem ok except when the car had stopped and the voltage was 11.2 volts but that has not happened again. In attempting to analyze the reason for the DTCs, I used VCDS Advanced Measuring Values for Battery Regulation 61 and noticed that whenever Generator Interface was Not OK then the Generator Voltage was 14.5 volts and when the Generator Voltage would rise higher that 14.5 volts e.g. 14.7 or 15.0, the Generator Interface became OK. Additionally, I tried to find out from Ross Tech Forums for VCDS where the Generator Voltages (Group 1 and Group 10) are measured to understand why both are not the same. No success from there. Obviously, they are measured at differed points for their values to be different. Key Position Engine Condition Time Elapsed Marker Group 1 Generator Voltage (specified) in Volts Group 1 Battery Voltage (actual) in Volts Group 1 Load Response Time in seconds Group 10 Generator Voltage (specified) Group 10 Dynamic Field Signal % Group 10 Generator Interface OK/Not OK Group 10 Generator OK/Not OK Accessory Off 0 12.00 12.35 to 12.40 3 0.00 0 OK OK Start Cranking 43 12.00 10.80 6 0.00 0 OK OK Start Cranking 44 12.00 12.20 6 0.00 0 Not OK OK On Running 44.96 to 2618 14.50 (constant) Varies between 13.35 to 13.45 3 0.00 0 Not OK OK On Running 2618.93 to 2645.64 15.00 (constant) Varies between 13.95 to 14.10 3 15.00 51.6 OK OK On Running 2646.51 to 2744.87 14.50 (constant) 14.10 falling to 13.35 3 15.00 41.9 Not OK OK On Running 2745.83 14.70 13.45 3 14.30 41.9 OK OK On Running 2746.78 15.00 14.00 3 15.00 41.9 OK OK On Running 2747.84 to >> 3019 15.00 (constant) Varies between 14.00 to 14.10 3 15.00 Varies between 41.9 to 48.4 OK OK Off Stopped car

Hi all, hoping someone can advise. Iv been searching everywhere for the info and it’s driving me crazy. Over the past year when buying parts etc, when entering my Reg im always given two options for my car. I understand there is a difference in HP & KW between the two, but wondering if it is vital I choose the correct one and if so, how do I find out which is the correct one for my vehicle. (It’s not on the V5) 171KW. 233HP 155KW. 211HP TIA

Hi I am shipping my US bought Q7 (2015, Petrol) to UK and wanted to ask if anyone knew where to get a light conversion so that i can register the car in the UK. As i understand the lights in the US are "red" and they need to be changed to "amber" for UK and then go through the IVA inspection. Any guidance or referrals will be appreciated. Thanks

Hi I need some help with a suspension fault on a 2007 Q7 i have the dreaded orange warning light on the dash, VCDS says electrical fault, the car runs fine suspension is at the correct heights and the adjustment on the MMI all works. Has anyone got any ideas on where i can start looking for the fault? Thanks

Good evening all, I'm new to Audi and new to the forum so firstly hello to all. I find myself here, hopefully like many other members before me looking for advice and guidance. I have an '08 Q7 3.0TDI which when bought already had 22" wheels fitted, I'm considering changing these for 21" wheels. After looking in to this I'm stumped and trying to work out best tyre size for correct wheel rim width and offset. It isn't helped because I've read somewhere that the 9.5J rim currently fitted may be considered too small for the 285 tyre fitted. The ET of the current wheel is 48. I'd really appreciate it if someone could point me in the right direction for a 21" wheel rim width and offset suitable for the correct tyre that keeps my speedo as true as possible. Apologies if this post is in the wrong area. Many Thanks in advance

Hi all. I’m Tom from the Uk 🙂 so I have a 2007 Q7 and I’ve owned it the past 4 years. It owes me nothing and i love the car. Over the years there’s been little gremlins that I haven’t had time to do anything about and to be honest they’re not show stoppers. But, since were all in lock down due to COVID19, I’ve got some time on my hands and wouldn’t mind doing a little DIY on the old bus, if I can. The beast pulls in every gear, full audi service history up till my ownership, which I now fully service every 6k religiously with OEM parts, except the gearbox. I have a specialist friend for that. 160k on the clock and the girl runs smooth! so, the little gremlins that id like to address are as follows. 1) DAB Signal - it’s really poor! More so when there’s something plugged into the 12v cig lighter slot or if the DVD players in the back are on. Is there anything I can do to improve this? 2) Front display TV reception - again really poor! It used to be fine, perhaps something to do with DAB signal too? 3) side lane assist thingy (tells you not to pull out on the motorway if there’s a car coming) - not working and comes up with when button is pressed. It used to work but stopped some time ago. 4) the rear passenger air suspension - is around 20mm lower when the car is parked 5) can I change the set ride height so that the car sits lower than factory without the use of the VAG software? 6) front heated drivers seat heater - temperamental 7) can I somehow retrofit something to connect my phone (iPhone) to the Bluetooth system to play music through the stereo? 😎 little square buttons on door handles. What are they for? Mine are not working at all 9) boot closing - closed 9/10 but it’s always that 1 time I don’t check; is there adjustment to ensure it closes ever time? 10) front side lights. No LED replacements work in these what so ever. Anyone got any suggestions? 11) how difficult is it to remove swirl flaps? One of my motors has fudged itself. Is there a step by step guide? 12) anyone blanked their EGR before? What’s the best kit and will I need to map it out? I think that is all. Massive appreciation to anyone who can assist 🙂

Got two discs I bought a few months back for a car I no longer have. OIEO £350

Hi, I have a 2008 Audi Q7 3.0 Sline and its driving me mad. Lately i get a wiper motor failure and also auto lights and auto wiper failure on the dash. There is also a rear passenger bulb warning. This happens first thing in the morning and all clear with either a restart of car or while driving. I have had a garage look at the rain sensor and they said it functions ok. The scan show communication issues or something along those lines. Today the failure came on and stayed on the dash but the lights and wipers worked where as before i had no lights or wipers until the fault clears. Please can anyone help me work out what is causing all this??

Hi all Had my 2007 Q7 for a couple of weeks lovely car, I do have a few small issues that i need to address. First is the MMI system all works perfectly except the SETUP button which does not illuminate when pressed or do anything on the screen, all i want to do is change the clock to the correct time but can't do it. I have seen it is fairly easy to remove the switch plate from the centre console, do i need to buy a new micro switch for this can i buy it separately or is it part of the complete MMI switch system. Any advice would be great thanks.

I have just bought an Audi Q7 S line 2006. Im thinking of buying the play2air Bluetooth connection so I can stream the audio from my iphone but I cant find the 10pin connector anywhere? There is nothing in the glove compartment apart from the airbag switch. the car is equipped with MMI with satnav, phone etc, although its not letting me import my contacts for some reason? Can anyone tell me where to find it and how to import my contacts to the MMI? Thanks,

Hi all quick introduction by me. Bought myself a Q7 2007 3.0 TDI back in September 2017. Top spec, every extra. It’s running around 140k now and I !Removed! love the bus! As do the kids and mrs. I carry out most of the maintenance myself. I’m a chartered engineer and I’m a massive car enthusiast, completed the majority of my own issues since I was a young teen. My previous car was a 535d and although I do miss the raw power, the q7 is my baby now and I will run it for many many years. Fingers crossed I’ve had a couple of problems with it. Passenger wiper arm snapped on a rainy winters day. Headlamp bulbs blew (gosh they were pricey). Going through 21” tyres like no tomorrow and just changes pads and discs all round. So no problems I suppose. Just general upkeep. However, I’ve just got a low oil pressure alarm. I’ve read some horror stories and current situation is...I’ve ordeted a new oil pressure switch/sensor. (Can anyone shed any light on its location on the car?) I hope it’s just a quick sensor change and I’m good. I have an oil change booked in too for next week. I have read horror stories about the oil pump though? Anyone shed any light on this?

I just bought a 63-plate Q7 SEwhich doesn’t have Xenon headlights or LED DRL, just the standard halogen bulbs and reflectors. The DRL is the same bulb as the main beam. I’m looking to upgrade the lighting, but short of buying a set of new headlight assemblies, what is the recommended ‘plug & play’ upgrade? I’ve checked autobulbs direct and the Halfords website to find out what bulb fitments are for my cat, but they gave different answers, even thought I entered my reg number to find the vehicle. Any help appreciated. Thanks.

Hi Everyone. I have recently purchased a Q7 and I am now looking to buy either a TT or A4 Cabriolet AUTO. Given my budget the age-range of these would be from 2003-2006 I Imagine. By the sounds of it the biggest issue with these cars is the cambelt, just wondering if some Audi experts can give some advice whether these models/age would be worh pursuing given the issues. Thanks

Hi there, took delivery of my new Q7 a little over one month ago, new 2018 S line, with tech pack and pan roof. I previously had from new a 2014 A6 Avant SE ultra tiptronic. Bought the Q7 on the basis of me previous Audi's reliability, practicality and comfort. Have to say was a tad overwhelmed by the Q7, it size, the gadgets, the looks etc., but now feel right at home. I've done just over 2K and averaged just over 31mpg, the A6, which the wife now has, does mid to late 40's. a bit miffed though that I am having to add "ADD BLUE" already. The A6 did nearly 8'000 miles before it's 1st warning came up?? Is this normal for the Q7 or have Audi saved money by only putting 3'500 miles worth in the tank.... Also wish it had some storage boxes in the back... Will update now and again, hope someone has some comments on the add blue... Cheers V12

Just bought my first Audi Q7 3.0 TDI S line 2006. Had no issues connecting my iphone 8 via Bluetooth but it wont import my contacts, I have read many reviews that talk about Audi dealer resets but is there anything I can do to get it working? Also, I would like to play my music through the car, I have heard tune2air is the best Bluetooth device out there but first does anyone know if I need this, the car has sat nav but when I go to CD option the only source is CD. Apologies if I am simply navigating the wrong menu, I haven't had the time to have a good play with it yet : ) Thanks in advance.

Hi all, Ive bought my first Audi, a 2007 Q7 S Line, a really nice car. Im looking at maybe fitting DVD headrests for the kids as the car currently doesnt have them in. Do you know if there is wiring etc currently in the seats you can simply buy an aftermarket headrest and connect it up or would this be something id have to wire in direct from the headrest to the dash? Im also thinking of retrofitting a reversing camera, again is this an easy option to do afterwards and would the wiring for the camera already be in the car and its a case of just fitting and connecting? Im guessing that would be far too easy so probably not! Many thanks, Foz.

Hi all, just joined the forums after buying my first Audi, a 2007 S line Q7. Im new to this level of car but after driving Fords, Vauxhalls, Citroen, Kias etc for many years the Audi is way above these kind of cars. Got a new little things i want to sort out on it so im hoping i can learn some things about the car from you guys! Thanks for all your help. Regards, Foz.

I am so excited, we have ordered a new Q7 and cannot wait for the car to arrive. But then began the worry about if I have chosen the correct colour. We have specced Sepang Blue, which is a lovely colour and I have seen other Audi's (SQ5, S3 etc) in Sepang blue, but never seen a Q7 in the flesh. Photos online do not always look right. I am thinking about changing the colour to ink blue or daytona grey to make sure this great car looks 'stylish' and 'prestige', I am concerned that sepang blue may 'cheapen' the look of the car. What are your favourite colours for the Q7?Should I stick with Sepang Blue? Not many of these about, whats the reason for that!Great dilemma to have I guess, but cannot make my mind up!!Craig

Hi all, with the new laws in England starting in November regarding children booster seat having a full back up to the age of 12 , I went to buy a new seat for my 5 year old. purchased a high back seat from Halfords and when trying to fit realised due to the head rests in the Q7 this wasn't going to fit! My wife drove to Audi and asked if they had come across this problem to where they replied, No. sales rep tried fitting a audi kids seat, this also didn't fit. the manager said the headrest can be removed but would take upto 5 hours ( £85 x 5 = sod that! ) anyone else come across this problem?
