When the message drive system fault happened the car did not accelerate normally and only built up speed very slowly.

I had my car inspected by my local Audi specialist garage, the drive system fault errors were related to a turbo under boost issue. Unfortunately the garage were unable to recreate the fault but recommended to change the MAP sensor as that was the first error appearing. 100% solved the problem. My car is a 2019 Q5 2.0 40 TDI Sport.

Ha I am receiving email notifications lesson learnt Gmail now has a few labels in the in box like important, promotions etc I have set this site now as important so I shouldn't miss anything when asking for help , For Audi A4 A6 Engine Dipstick Funnel Insert Guide Locator 06B103663 is the part my partner order as its her car, this part push on and seals perfectly I had to bend the top bracket very slightly as a location on the tube is to wide it is loose on the bracket so just a simple cable tie did the job, might sound a bit of a bodge but it works.

Peter, what model, year & engine was this for please. I’ll look at LLLParts catalogue and see what I can find. For anyone else looking to do the same, I think an easier route would be to look for a tube from the same engine from a slightly earlier build, all the V6 single turbo engines are mechanically identical (or so I’ve been told by a number of specialists for my MY [2015]), it’s how I got a dipstick for mine, I looked at the items list for a 2012/2013 model. Ive been using ‘LLLParts’, who use a fairly comprehensive an online illustrated parts catalogue. you can search by year too, which made it easier.

Thank you for the explanation Peter, and due to your sign-on procedure, I now have doubts that you will even see this reply! I think the lesson is that if it’s important enough an issue to seek advice on, then it’s well worth returning to that request source to see if any responses have actually been posted - irrespective of whether ‘some system’ advises you to do so or not. Still…. ‘Onward and upward as we say. Re. your interesting reference to buying a different one and modifying it, would you now be kind enough to share the part number of the one you bought, and what the necessary modification was. I’m sure this information would be useful to others at some point in the future. Kind regards, Gareth.

Hi yes its the switch on the pedal, it could also be the brake light bulbs so check to see if working from the research I have done it appears the switch is a common failure. Steve.

UPDATE: Timeline (Within 2 weeks since dropping the car) I have some great news to share with everyone. With the help of a couple troopers @Mark2 and @MikeyW Both member have been more then helpful by providing me details which I requested. I built up a couple cases related to RS6's which was outside their 3 years manufacture warranty as mine also is 3 months out and the dealership tried to play that card! Little persistent with Audi UK explaining that the 48V system has a critical flaw and the risk it can cause with it failing is detrimental. Audi UK not taking liability for replacement on the failed alternator which is part of the drivetrain is out of the question and must be pursued out of principle. My dealer initially did not agree with the warranty claim and told me: 1: The part number on your alternator is not covered 2: Your car 3 year warranty is expired Audi UK will not cover 3: Your car has modifications so any warranty is voided (They are wheels and exhaust) 4: Your car is not covered by the 7year drivetrain warranty 5: Audi will not cover it under goodwill After a meeting with the service manager he ultimately agreed that Audi UK should compensate 100% on this and has put this forward to them. I compiled a list of supporting evidence for the local dealer as proof of a major problem with the alternator: 1: Copy of Audi US letter to customers of the 7 year drivetrain warranty extension 2: Copy of the Audi Technical Information related to the failed 48V Alternator 3: Gov.UK Audi alternator recall campaigns related to other model 4: List of forum threads highlighting the 48V alternator failing with same characteristics when fail 5: 2 cases including customer name/ reg/ dealer that was successfully claimed through the 7 year drivetrain warranty when vehicles outside the original 3 year manufacture warranty – Thanks again @Mark2 @MikeyW With point 5 its check-mate for Audi UK to deny anything but to accept liability. After emailing point 5 detail to my dealer yesterday I got the answer we want today: Email from my local Audi dealer: "Good morning Thanks for the extra information. Nigel has now managed to get the repair covered for you so there's nothing for you to pay! Parts were ordered yesterday and have arrived with us today; vehicle will be going into the workshop later today for the repairs to be started and we will be looking at some point next week for it to be completed. I'm hoping I will have a better understanding of the completion day by tomorrow so ill be in touch then. Many thanks.
