Hi my 2017 Q3 as screen backlights have gone and it’s now black, I read that the wiring can snap due to the constant twisting of the screen. As anyone got any idea which wire from the back of the multimedia unit controls the power so I can check it with my multimeter. thanks

Hi sorry Cliff I stand corrected.

Hi the one with only one connection is for the low pressure EGR, the sensor with two pipes is the DPF sensor they are both the same part number but the EGR sensor on the low pressure side uses barometric pressure from the open side to make its calculations, replacing both is not a bad shout but they will both need adapting, I would still be interested in your soot/ash loadings. Steve.

Hello! First of all I'm terribly sorry if this topic has been talked about, I just want the most up to date infos. I'm in need of a reliable daily that doesn't eat my wallet but looks nice. I'm kinda fallen for the 2.0 TDI A4 B9, 190HP one in particular. I see a few for amazing price, (my budget is about 15.000 euros). Now I would like to know should I be scared of the cars that have 170-190k mi? What should I look for when looking at any B9 with this engine? How good is the S Tronic, and should I look for a manual or S tronic? How easy is the DIY maintenance on these? Turbo and Injector life? Quattro or not, doesn't really matter to me. Any extra advice and stuff I should look for or something that costs a lot to replace would be very nice to know, so feel free to post anything that touches this topic, and maybe some topics I missed. 🙂 Greatly appreciate all inputs!

Watching with interest, thanks for posting. im about ti replace front dampers, top mounts and anti roll bar links on my A3. the top mounts are getting a bit creaky. Dampers look to be originals and with the car past 100k miles replacing them can’t do any harm I suppose.

I should also say that I have seen the service books with stamps. I will view the car next week. I just want to do my research before making that journey.

Hello David, To my logic, the suffix A denotes an earlier version of your later B, so possibly from a pre 2009. Significance?? If it remanufactured as opposed to just ‘secondhand’, then the remanufacturer will/ should have the experience to answer any questions about specific differences. Have you asked, and have you had a reply? Kind regards, Gareth.

You will never have such bad trans fluid when u NEVER do launch when u never drive like maniac .. In the past people were owning cars and NEVER EVER thought that they gonna replace trnas. fluid.. ONLY engine oil... Nowadays people doing all sht on internet just to make money from views so they will replace all possible nonsense on car.. When people suddenly shoot off from stop and step on it.. The trans gears making massive friction where micro chips happening from metals.. Nothing is undestroyable in the world.. If you never do all these car abuses your trans fluid will be STILL gold after 5 years or even 10 years of driving car...

Oh dear. I can safely say I won't be trying that myself. Thanks for the heads up anyway Steve.

Not been doing too much too her fixed the exhaust on properly and been looking for the red interior, last night had a good touch got a full set normally 600.00 to 1200.00, I won this for 136.00 yea totally stole it

Hi I am a new member. I have just had timing chain and cambelt changed on my 2006 plate 2.0FSI Quattro and now I have this error. P0011. I have a cheapy OBD reader that says it is something to do with the cam timing. Can anyone add any useful information? I will take the car back to the mechanic but just wondering if anybody else has had this.

Did anyone try a different flywheel in the end? I'm likely needing to replace my clutch soon so I'm tempted to try fitting 0B2105266L

Happy to say I got the car back on Friday and all appears well. new high pressure pump and a list of other parts as long as my arm, gave it a good run around over the weekend and all good.

Hi Nick, Nice car. No I lost the will to live and gave up. Got a different seat with the spindly leg at the front which I'm not convinced would be as good as a top tether. Fitted 2 genuine Audi isofix bars myself not cheap. The images above show a part number can't guarantee it. But I think you could only fit one top tether seat as the recess is only on RHS of the back of the seat. Seems to me that the Americans had a solution but was unable to find out. Good luck. Let us know. Steve

Looks great, very similar to my 2011 but mine not the Le Mans. currently at 165,000 miles. What did you sort the rear lights out with? the standard polishing kit? Also next time you have it plugged in any chance of sharing the exhaust temperatures - pre turbo especially - we my other thread!!🤔 All the best

Thank you, it’s already in the garage tomorrow for a faulty top shock mount, so I’ll get him to check it out Linda

Fixed. Car was in and out within 2 hours! Happy that it's now locked down.

Hi Andy thank you for the update it gives the forum value and continuity. Steve.

I have a 17 plate A7 3.0 TDI (272) motorway was getting 40 to 45mpg on local roads closer to 25 to 30mpg. Had a stage 1 mid map (320bhp) now getting 30 all day long on local roads but motorway now sitting at a comfy 50 to 55mpg driving at 65 to 75. Extra oomph is a bonus when needed.

Will be too late now to arrange a stand.

Done

Hi all, im not looking for assistance im logging my warranty issue here for those who may have a similar issue for assistance/ diagnosis. vehicle effected: MY2023 40 TDi Quattro, 10,127 miles. symptom: vehicle displays drive system fault randomly at no given reason performing attribute causing vehicle to go into limp mode. Turning the car off and on again resolves limp mode. Extremely poor MPG (average 34mpg combined driving). Cause Fault codes: relate to air mass flow sensor recording incorrect parameters causing vehicle to go into limp mode. (Code to follow) additional fault code: relate to ‘reductant System’ ad-blu pump flow rate too low or ineffective. diagnosis verdict: warranty claim, replacement mass air flow sensor and pump. Concern is the car is trying to compensate for emissions out the exhaust as a result causing the air intake parameters to adjust outside of the required normal numbers. For good measure the dealership has decided to replace both as the indication for the air sensor has been two occasions where the car has broken down as a result of this fault code (recorded by Audi assist).

Just realised I posted this in the 8p forum. Can a moderator swap this to the 8v section please ? thanks

Re the rear brakes, have you noticed excessive brake dust build up on either/both rear wheels? This can be an indication of a binding caliper. maybe raise the rear wheels and see if the wheel/wheels rotate freely without too much binding. if the caliper is binding badly you will notice the brake disc becoming hot after a run.

Hi Gareth, Yes, very similar issue. Audi A3 Sportback (8PA)1.6 2013. Keep getting ESC Traction Control & ABS lights coming on intermittently and car juddering and sometimes cutting out. Sometimes it just clears itself. Sometimes it's fine and sometimes it just doesn't start. I have OBD Eleven so can get fault codes etc. It is actually my daughters car but she got fed up and bought a new one. Plan is that i have it as it better than mine. Not really looked at it much, just picking up tips from this forum. All i have done to date is changed 1 Wheel Sensor.
