I originally had intermittent heat, this then became no heat. I just googled around to see what the issue could be. That pointed me to some coolant “bag” issues some people were having. this related to there being silica bags that would burst and cause a blockage in the heater core which in turn would lead to limited or no heat. if you have a helpful garage close by you could ask them to flush the heater core for you. Or there are videos online if you’re confident with trying this yourself.

Hi, I had very little knowledge or experience with cars, so the steps I mentioned earlier were as far as I could manage on my own. Fortunately, I found a mechanic who was able to assist. I’m not entirely sure how he managed to slide the core out, but he did, and he replaced it with the part I had sourced. That resolved the issue completely. I believe I paid around £100–£200 for the repair, which was significantly cheaper than the quotes I had received from Audi and other garages. From what I saw, a flush might have worked as well, as the old core was clogged with a lot of debris. If you’re facing high repair quotes, it might be worth trying that first. Sorry I couldn’t be more helpful, good luck with your repair.

Hi, currently trying to replace blocked heater core. so far have only got under glovebox and realised I can’t actually slide the heater core out due to another part blocking its path out. anyone else done this and have any ideas? do I just need to start removing the rest of the part(s) under the glovebox? picture attached - the part I’m talking about is the black box to the left of the heater core. thanks

Hi all, I’ve got a confirmed c123efo code on my Audi A4 (2016) and have been having some difficulty in finding someone that can help fix this. I’ve seen ecu testing are able to resolve the issue on the abs unit, however, I can’t find anywhere that is able to remove the abs unit so that I can send it over. Any suggestions? Or better yet, does anyone know of any Glasgow based garages who could resolve the entire issue? Thanks,

Has anyone else had any issues with AC? I have intermittent issues with no hot air, when it is hot its not that hot... Demisting is also a pain!

P3N - How did/is this going? I think legal action is fair, the fault has clearly been a manufacturer fault that's been there from the beginning - hence the many affected users on this site alone. However, the trouble will be you will need an engineer's report to confirm that as evidence in court. I was thinking of doing the same, they might not bother to send anyone to defend a small county court claim. FADEC - I haven't noticed any difference in braking and have had no issues or complaints. I did some emergency brake tests after changing the sensor and again no issues, very responsive and no locking. 123456789987654321 - The error comes about once your car registers the fault 20 times. Once that happens it bricks the ABS which apparently then cant be reset without replacing the entire unit (£3,000 by the looks of it) or by having it removed by a garage and sent to be reset by a 3rd party (between £400 - £600 from what Ive seen). IF you still have the brake servo message, you should be fine and just need a new sensor. If its changed to a brake fault message your ABS is gone.

Hi back again... Got the sensor swapped over today, however, can't get this 'brakes:fault. Safely stop vehicle' nessage away. I've only got a Bluetooth obd and phone app that I use. Will it be needing a visit to a garage for an actual diagnostic machine (quoated £40) or has anyone had luck with a certain app?

Just came across this thread.... I've had this issue for 10months! I've done 1000's of miles! Must be very lucky for it not to have developed an ABS issue. Have ordered the part via Ebay - £10.00 - and will replace ASAP! Thank you to the user (ALO I believe) who uploaded the how-to video!
