Took the car for a diagnostic check today, not to an Audi garage, and the fault that was displayed was no communication with the auxiliary heater, would this cause a problem with the air conditioning.

Hi guys, recently bought an audi a4 on 110k miles. since buying the car for £2000, i have spent nearly the same in repairs and garage fees. it has not been kind to me. Recently got the car back after having a new timing belt kit, water pump, 2 new camshafts, aux belt - the list goes on. within a week, my EML came on after dropping down a gear and i have loss of power after around 2600 revs, along with a flashing glowplug light. ive been told by a friends "mechanically minded" dad, that the turbo is goosed, but then i have also been told it probably will be the EGR Valve or even a boost pressure sensor! good to mention that there is no smoke on acceleration etc. codes found when plugged in: p0299 05171 confused is not the word. Any help is greatly appreciated as i genuinely think im going to write the car off at this point.

I think you'll need to get this booked into the main dealer as MMI issues are well documented.

Looking on autotrader of 24 models onwards most are not hybrid and all the 204ps ones aren't hybrid.

Please keep us posted on how you get on 🙂

Yep it will do.

Thanks for the detailed report Vytautas.

So i have done the Heater core matrix change and it was not difficult without any mechanical knowledge, however would recommend to have someone to help you as at some stages it looks like you need another pair of hands just for holding a pipe in position or a torch. Started by removing the glove box and some covers on the passenger side: Then you will be able to see the heater core and pipes. After this, remove the media unit and disconnect all cables, all colour coded and different types of connectors, so it will be easy to connect back, but just in case, take a picture for reference. Remove the foam cover And remove the fan, few screws holding it. Remove the sensor in front of the heater matrix, which is blocking the bottom part of it. Place a tub under and start loosening the pipes. After that, push the pipe out of the way and slide the heater core out. Change the core and do everything back in reverse. I have bought new seals and clamps as well for the pipe, don`t need to, but it was just in case. Would at least recommend changing the seals. Was very difficult to alight the pipe and at the same time tighten the screws when putting back together as there was not a lot of room and make sure you put clamps facing the same way as they were due to not blocking the plastic going back in at the bottom of the heater core. Prior to the task, I completely flushed the coolant and changed the coolant tank, which I bought for 30£ as there was a lot of residue sitting at the bottom of it. Job done in April. Any questions I will try to answer when I can. Thanks and good luck,

the hard rise i am used to most of my prev cars have had it , ie /golf tdi, seat frtsi all have a hard ride and road holding superb, but the road noise is excessive with the audi a1 i have bought ,i have had suspension etc all checked over ( no faults i have read that the 16" tyres with low road noise work better than the 17" inch ones , thank you for your reply

John. Do you have question or did you join the forum merely to rant?

Upgraded hybrid turbo from turbo technic or similar. Powerflow for the exhaust. They have suppliers nationally.

It really couldn't be simpler or more straightforward if you've got two keys mate.

Oh super job I’ll try that out later thanks very much appreciate that dave I replaced the key batteries yesterday so I’ll watch the video later thank you

It already has a turbo or do you mean another ? And in regards to parts, do you know anywhere I can get them sourced ?

Good afternoon All. Can anyone tell me if the front o/s wing on the A3 2009 will fit my A3 sports back 2010, please.

Seriously mate, I'd try this method first as it's really simple (especially as you have two keys), works perfectly, and is so idiot proof even I managed it at the first attempt. You don't need to mess around with the VCDS clearing memory slots or anything like that and you'll have both your keys programmed in two minutes with zero fuss. I'd change the batteries in them first to save messing around in the future. The information and instruction you need starts 9.00 minutes into the video. I wish I'd found it ages ago as it would've saved me a load of hassle in the past. Let us know how you get on please. 2003 A6 C5 key reprogramming (two key method) - Audi A6 (C5) Forum - Audi Owners Club (UK)

Hi everyone, I'm thinking of buying the new A5 petrol front-wheel drive 204ps model, but I'm not the biggest fan of Hybrid or mild-hybrid cars. Somewhere I read that the whole new A5 series is mild-hybrid, somewhere else that only the A5 Diesel and S5 are mild-hybrid. I didn't manage to find a clear answer from the official site. Does anybody know please?

I have a 2021 Audi A3 edition 1 and I’ve had issues with the automatic online maps update. It has been stuck on installing for around 6 months now and I can’t seem to get rid of it/get it to finish. If I click the banner in the attached photo it just takes me to the updates page which just says “installing…” so I can’t access any of the manual update options or cancel the update. I’ve tried a full factory reset, soft reset, plugging in a USB with the maps update on and calling my local Audi who just told me to use apple car play 😂. Any advice would be greatly appreciated!

Thanks Brian - I agree. These parts don’t seem very robust.

Hey, tried this with my Audi A3 2021 Edition 1 and there wasn’t anything really exciting. All I ended up doing was turning lane assist memory on. If you have the obdeleven app you can preview what apps/features it thinks will be available for your car (even if you don’t have one yet) and I found it to be mostly accurate!

Okay, thanks. Roger

It is a bit. But, Audi South East said they can do the checks in a day, which is better. so, it is booked in this Wednesday 2nd July.

Hi Audi A6 C8 50TDI Quat MY2020 bought from new owner here. Pretty sure my MHEV 48V system will be more or less identical to the A8. I had the similar electrical issue in Jan 25 described here, which was originally diagnosed as needing a new Starter Generator. The diagnosis was then amended to needing a new Starter Generator belt tensioner. This fixed the problem. Last week I had Electrical Failure with the yellow and red battery symbol along with the associated messages and sequential shut down of the A/C and MMI. When I tried to start the car, it would hardly turn over. Started it with my NOCO jumpstart which got it going. As the battery was clearly drained - probably as the result of getting no charge - I put the car on charge using the under bonnet red connector and nearby negative lug in accordance with the handbook. The following morning, I drove the car to Audi with as many electrical services switched off. Managed to cover the 15 miles ok but not sure how long it would have lasted for. Having done some research on-line, I found that a failed starter generator replacement is now a free of charge fix. This was great news, as the car is 5 1/2 years old. Picking the car up later this morning. Total time with Audi was 5 days including a weekend. It was a very good outcome, but I am concerned that the new part will be the same as the old part - but hoping it has been modified. Details for the A6 FOC repair are below. Not sure if it applies to the A8, but certainly worth checking. Recall reference R/2020/265 Recall Type Car Recall Date 2020-10-02 Reason for concern MOISTURE MAY ENTER THE BELT DRIVEN STARTER-ALTERNATOR Reason for recall It is possible that moisture may enter the belt-driven starter-alternator. Remedy The starter-alternator must be replaced on the affected vehicles. How to check if the vehicle is recalled Contact the local AUDI dealership or manufacturer. You will not need to pay for anything involving the recall. How the manufacturer will repair The Recalled vehicles will have the fixing checked and corrected as necessary by and official AUDI service. AUDI Reference ID 27H8

Hey thanks for the offer but I am not looking for a 2.8 engine and no Avant I want a Saloon But thanks for the offer 🙂

So stage 2 straight through exhaust such as powerflow etc. Better injectors, turbo and intercooler. Then remap. Don't forget to get the gearbox mapping looked at afterwards too.
