Common Good practice is to carry out a pre repair diagnostic health check to A protect the garage from pre existing faults and B to give the customer pre warning to faults that they may not be aware of, I can see this from both sides that to put your car in for a new DMF shouldn’t result in a undrivable car being returned but also changing a DMF while a time consuming job is relatively straight forward. Are the Audi dealership that replaced you DMF saying that the previous Audi garage have a record of another fault saved against your car, if so request proof of this as it’s your vehicle should be accessible to yourself upon request

Hello all, have any of you upgraded your air filter or even fitted a different air intake system. If so, what was it? Price ? Were there any differences in noise? Look forward to your replies Mark

I’ve just bought one of these brand new from a company called Germanmodsuk. £205 brand new.

Following this as i am interested in fitting one myself. No phone or bluetooth in the car is annoying.

My car won’t start put my little tester on and this is what it said I haven’t a clue it’s Christmas Eve Eve and I need my car so no garages open any help or advice would be really appreciated thanks

If only it was that easy, not listed.

Hi its probably in the owners handbook just a case of scrolling through it and finding the correct fuse box diagram and fuse number. Steve.

Keep us posted on how you get on

Have you looked at eBay or AliExpress for the mudflaps? Regarding the bulbs make sure they're the type that won't throw up a bulb out message.

Found 1stChoice spares asked for a search with them and they had nothing so they asked me if they would let me send out my request to some of there breakers they dealt with and they got two replies MGS Automotive LTD **** ECO Auto parts Parts *****

Hi, I am new to this forum and just bought a late 2024 74 plate Audi Q7 S line black edition and wondered of anyone could point me towards some decent mud flaps. I am aware that Audi do the hard plastic ones, but hoped to find some rubber ones that bend and deflect debris. The factory number for the Fronts is 4M0075116 and the rears is 4M0075106. These are for the S line which is apparently different from other bumpers I am told by 3 dealers. Any pointers towards a set of decent rubber mud flaps would be helpful. Also, has anyone tried the LED bulbs for the reverse lights on the newer Q7? Any pointers on a high quality LED bulb that is road legal would be nice, the incandescent bulbs make you squint in the dark. Thanks

Well I thought while I'm at it I kight aswell do a service especially as she has just hit 260,000 miles 😅

New topic please. I am locking this one.

I also will have a repair day tomorrow, Oil Pressure Switch.

I didn’t reset the MMI when the tyres were fitted but I always reset it after checking the tyre pressure. Well that resolved this issue, I have a second issue with regards to my rear spoiler fault, do I start a new topic or carry on with this thread?

Yeh there's isn't any codes that have come up it's a bit of a nightmare but thank you I am having a day of repairs tomorrow so will let you all know the outcome Tha ks again

i will try to code the lane assist first,thanks will tryout definetly !

A shame you did not mention that earlier. Whenever you swap wheels or change the pressures the TPMS needs to be recalibrated.

After many looks online, no fuse position that has been told me has been correct for rear wiper on a 2020 Q7 mehv black edition. Can some body please tell me which fuse box and which fuse is for the rear wiper?

So pin 1 is a earth and pins 2 and 3 are live feeds for the bulbs and missing pin 4 is redundant on this model of car, have you check that your getting a feed to each bulb and a continuity check from the earth track to a ground on vehicle chassis

there is no track for the black and white wire in the bulb holder lol

So the black and white wire going into the plug doesn’t have a contact connector inside the plug and the bulb holder has no pin either, never seen thing that’s the case and would suggest it it possible it’s corroded and arc’d to the point there missing as the wire would need the connector on the end to hold it in the plug, could strip back the wire and jump a lead from the wire the the track on the bulb holder and see if that solves your problem

Just make sure you reset the system in the mmi everytime you change the tyre pressures but yes your right the rear will now rotate ever so slightly more then the front at high speed on a decent drive , the system is very clever as takes readings from the steering angle sensor to compensate for for the differential in front wheel turning rotation.

Never a bad idea to get a scan, pdc sensors usually throw one of 3 faults, short to ground, circuit open or no communication. Any one of these in a single sensor will stop the system working and so you would get a warning message on the mmi when system activates. I would be looking for a missing message issue between 2 modules relating to the pdc and gear selection/speed as if there working but not how you think they should
