  1. The suspension issue you mention shouldn’t drain the battery overnight but I did have a similar issue on my previous Q7 which turned out to be the auxiliary heater. Wouldn’t drain it every night but maybe once a week. Only tracked it down as one morning when I went out to the car I could hear a small fan noise from the passenger wheel arch. A scan of vcds showed “auxiliary heater locked” it wouldn’t unlock and is quite common on older cars to fail as I’d noticed it didn’t work when I bought the car. Removed the auxiliary heater fuse from the passenger side of the dash board and it cured it. 🤔 it might have been the drivers side dash board but think it’s the passenger side.
  2. Yes but the earths that corrode are accessible from under the car and aren’t the easiest to get to but yeah you can clean them up. Easiest thing to do is get a jump lead and put it from somewhere metal on the engine and the negative terminal under the bonnet on the passenger side and try starting the car to see if it makes a difference. If it turns over quicker then it looks like the earths are corroded.
  3. Sorry I put dpf sensor I ment egr sensor
  4. It looks to be pointing to something on the exhaust side. The torque intervention is usually caused by a restriction or pressure issue which I’ve seen when dpf’s are clogged but it’s just a safety thing to stop the turbo getting damaged and if it was a dpf problem there would be other fault codes. The first place I would be looking is the turbo actuator then checking the dpf and sensor even if somebody has already changed that at another garage it’s worth checking over to see what they did. Did the car seem down on power or smoke in the days before it went wrong
  5. Have they said what fault codes are coming up when it goes into limp mode? At what point does it go into limp ie under acceleration/ as soon as it’s turned on/ at a certain speed or rpm? Etc
  6. My 2014 did something similar when I got it. The start stop often had the deactivated symbol on the dash and on the occasion it did work it didn’t restart the car and would beep and put error lights on the dash. Turning the ignition off and back on would restart it but slowly. That was caused by a faulty battery. Replaced and it’s been fine since.
  7. Oddly enough mine did this on Saturday just gone 😂. It was a faulty rear left abs sensor. £55 from Halfords (eurocarparts want £77 for the same Bosch item). It threw the tpms light up along with the traction control, and and the suspension light up and the traction control kicked in and wouldn’t let the car set off for about 1-2 minutes then the car realised the readings it was getting were false and let it drive away and worked fine but the lights stayed on even after turning off and back on again. it’s held in by 1 allen key bolt but can take a bit of wiggling to get out.
  8. Yeah I got one like that. Stuck it in the rear quarter panel and worked fine
  9. 2011 was the year that the car got an 8 speed gear box instead of the 6 speed in 2010 and earlier. I think there was a slight facelift too and a slight engine refinement but the main difference is the gearbox which makes it better on fuel and nicer to drive on the motorway. It might of got the start stop too. Early 2011 cars (60 plate) and some early 11 plate cars probably won’t have the revisions. Get one with the 8 speed box it’s a lot nicer to drive
  10. Sorry it connected to the rear of the sat nav dvd drive which was in the boot in the spare wheel well on the drivers side. You need some Audi radio keys to remove the drive to get to the connection
  11. Had this before and it was down to a faulty shark fin antenna on the roof. I bought a San nav magnetic antenna from eBay (about £8) and fitted it in the boot. Worked perfect after that.
  12. It was definitely ecutesting.com that I sent mine to not cartech. They confirmed mine was faulty but didn’t have one to exchange it with so refunded me and sent mine back.
  13. I’m inclined to think it’s possibly an ecu fault. I suspect when you loosen an injector pipe and crank that you’ll get a diesel but might seem a little bubbly making you think it’s drawing air in and lead you into an expensive world of changing components on the fuel system. I would look for a local independent mobile auto electrician to come and test the ecu etc. Should only cost a callout and be less than £100 and might save a lot of chasing. Alternatively you can send the ecu away to be checked/repaired 🤔 there used to be a company on the internet ecutesting.com that charged about £250 to repair/exchange them but if no fault was found then they refunded and sent back but you have to pay about £20 postage. I’ve had a similar fault like this before and it got very expensive to chase and sort. ( it was the ecu in the end but I only found this out after about 2k into it 🤦🏻‍♂️). Theres a post about it with all the symptoms somewhere earlier in the forum posts.
  14. Hi did the car cut out when driving or simply not start one morning? Did the glow plug light flash at any point?
  15. Crankshaft sensor. I’ve had that fault before. Won’t have any fault codes stored either.
  16. Saw something similar a few years ago. Turned out to be the starter motor. It would start when cold but cranked a little slower than it should but once the car was warm it wouldn’t even crank until cooled.
  17. I’m tempted to think it’s possibly a sticking/fault turbo wastegate but I’d of thought it would have thrown a code for boost pressure negative deviation or something similar.. Does it do the same thing on idle if you rev it or is it just when under load in gear?
  18. 2007 did around 18mpg not 180bhp! Auto correct 🤦🏻‍♂️
  19. I get around 23mpg on average around where I live which is quite hilly with most days the car not doing more than 5-6 miles but on a run it’s easily over 30mpg. I had a 2007 which used to do around 180bhp where I live but I’d put this down to it having the 6 speed gear box instead of the 8 speed which cars after 2011 have and the engine not being as refined. 2014 seems to be the sweet spot for the 3.0 245bhp but like all cars there are exceptions. I’d say avoid cars without a religiously followed service history as sporadic history is usually a sign that the owner couldn’t really afford to maintain it and has opted to repair when things wear out. Common stuff to check Water level - if low take the engine cover off and check on top of the engine in the vee for smell/signs of coolant. It’s common for it to leak under the dpf cooler which is around £400 to fix as it’s a pain to get to. Suspension - lower the car to its lowest setting the raise it up to lift. It should raise quickly and without being noisy in the cabin. Usually if there’s a problem it will show itself doing this by the display greying out and a suspension light showing on the dash. Most of the time it’s the compressor at fault which costs the moon from Audi but copy’s can be bought from eBay and isn’t a big job to fit. Make sure it doesn’t clunk over bumps or pull on the road when letting go of the steering wheel or under braking. It’s usually worn lower arm rear bushes which can seize in the bush sleeve and be a pig to get out. Not expensive but awkward if not on a ramp. I have Pirelli pzero tyres on mine which have done nearly 15000 miles and don’t need replacing. I run them with about 42psi which seems to stop them wearing on the outer edges. My mate ran his on less and did a set in 8000 miles so we all run on 42psi. Unlike Land Rover it only has 1 battery which does generally last around 5-6 years before getting tired. Check in the display settings if the daytime running lights have been turned off and the time the lights stay on after the car has been locked has been set to zero as someone trying to hide the fact it needs a battery will have done this. Turn the lights on and the heater on then after about 10-15 seconds try and start it. It should fire straight up within a second without any hesitation l. Also a failing battery will disable start stop. About £300 for a battery and about 45 mins to do it’s under the passenger seat. Heated drivers seat usually never works and is a good haggle point. It’s a common problem that the element break’s usually from a wallet in the back pocket or from kneeling on the seat. Not the end of the world if your not fussed but Audi want £600 to sort it. probably a few other stuff but I can’t think of anymore for the min. I’ve had 4 of them now and once you’ve had one it’s very hard to find something else 7 seater that ticks as many boxes as it does. I’d say 2014, under 80000 miles, full service history, panoramic sunroof is a must, and check general condition inside and out. If something doesn’t seem right for what the owner is saying then walk away as there’s loads of them out there for sale.
  20. Try putting a jump lead cable from the negative terminal under the bonnet or from the battery negative onto a good metal point direct on the engine and try starting it to rule out a bad earth.
  21. Under what circumstances does it stall? As in cut out under acceleration or stall when stationary etc. Do you get any warning lights (glow plug light flashing etc). Are there any messages stored in a scan?
  22. Might sound odd but does the rear windscreen washer spray onto the rear window? The rear wiper motor is designed stupidly to have the water run through the motor itself. The motor seals fail and when trying to spray water onto the rear screen you can hear the washer motor and the rear wiper moves but little to no water comes out. The water runs down the inside of the tailgate onto the light unit and corrodes it over time so if you just put a multimeter onto the terminals where the bulb goes it will show no power. Might be worth a check before anything else.
  23. LED lights around the headlight and the indicator strip is LED
  24. From memory the facelift happened in 2009 with the main difference being LED lights front and rear. That definitely doesn’t have LED lights. The next facelift year was 2011 where the bumper design changed slightly and the engine had a slight tweak for the emissions which resulted in a bit more power too. The gearbox changed from a 6 speed to an 8 speed.
