Hi again Gareth 🤦🏼‍♂️ My wife has just informed me that when the garage changed the battery they checked the old one and it had 55% left in the battery but it was only charging 10%. Please tell me if I’m wrong but I think you are right in saying the alternator is not charging the battery properly? I’m wondering why the garage didn’t say it could be alternator related? They just swapped the battery and it worked for a few days and then lost charge.

Cheers Thomas I did read about the know abs issues with this car. I will get my mechanic to check it. Many thanks

Yeah, that’s what we thought when the problems started to happen. So I had the battery checked and it was the original battery that came with the car. 2012.. it was changed with a Bosch battery exactly the same as what was installed. Yes the car was fine for 4-5 days. Then Lots of faults came back. I then took it to an Audi specialist who said it was because the battery wasn’t coded properly. My wife collected the car and then the faults popped up straight away the same day. It was the bank holiday weekend so I haven’t had chance to speak to the Audi specialist again. The engine management light is also on. It’s running pretty rough as well. I will ask them about the alternator check. thanks for your advice Garath. The car has been so reliable up till now.

Thanks Garath I am going to take it to my Audi specialist tomorrow, I will ask them to try and check the abs sensor. I appreciate your advice.

Hi My wife’s Audi 3.0 v6 TDi Quattro has been doing some strange things recently. Here are the main issues; saying Tires under inflated Stabilisation control (ESG) fault Parking brake Fault in braking system - contact workshop Headlight something, can’t remember exactly what Also happens: Steering heavy when trying to reverse, reverse camera didn’t work. When it starts flashing all the warning signs, the car revs change, I can hear the engine changes, it runs differently. Today: Speedometer kept dropping to 0 when driving, then rapidly moving up to 40 then back to 0. The car has been steadily getting more and more faults. Our Audi specialist mechanic thought it was the battery, so that has been replaced and coded. This solved the problem for about 2 days. Then it has become worse. I have read it could be a faulty main ecu? I have had a look at it and the outer box is very corroded, by the windscreen drain valve side. Can anyone help? Is it worth trying to open the ecu to see if there is any damage internally? Eg water ingress? I’ve seen you can purchase special bolts to open the ecu. Any advise would be very much appreciated. My wife is upset and I have 3 young children. I’m worried it will brake down in a dangerous situation. At the moment it hasn’t done that. Many Thanks
