Thank you so much for this video! I just fixed my 09 A5 3.2 based on your video. Saved me thousands. I did end up buying the voltage regulator directly from Audi. It was $256 but a local dealer had a parts special so I was able to get mine for $194. I also went in from the top of the engine compartment. I took apart the front end and put the car in "service position" and went in from there. Lots more parts to undo but it gave me more clearance to move around. I still had to go from under to disconnect the battery cable and the electronic connector attached to the alternator. Altogether, spent maybe $300 with the cost of parts and buying tools. Way better than the thousands I was sure to spend with Audi. Thanks Dave!!!

Good work on this Edit title and add 3.2 liter v6 makes it when searching

Okay dumb question, this message just came out on my car.. how long can you drive your audi before it leaves you stranded?

To be in the most money saving path what you coud also do is to repair that regulator by installing new contacts and cleaning the alternator shaft. 😁

I have similar issue with a 2013 audi q7. Changed the regulator and bearing while I was at it. After all cables being reconnected, the car turned on, placed in gear and the car died. I connected my OBDeleven and battery reads 9.2 Volts. Used jumper cables to get the car started but the entire dashboard lit up like an x-mas tree. From TPMS being faulty to adaptive headlights not working. I have read if a new battery is replaced or alternator is replaced, the battery needs to be coded. Not sure of the if that is legit. Does the the battery need need to be coded? I am out of ideas where to keep looking. What do you suggest?

Nice work!! I got my 2010 also 3.2 4 months ago. Sitting at 170k kms. I’ve looking all your videos. I did driver’s side CV boot replacement so far. Did you change transmission fluid? I bought fluid, filter and gasket already but still having doubts about the filling plug. Anyway.(btw OEM Lifeguard 8 fluid) Any wheel bearing replaced? Diff and center Torsen fluid? I appreciate your work, clean and straightforward!

I’m away from home and the fault shows up and then disappears. Can I drive 200 km or it will drop dead while I drive it?

Nice! I am getting messages about a failed alternator and I’m also having a cylinder misfire. Could the bad alternator cause problems with a spark plug? Grounding issue? Thinking of starting with this process to replace the alternator’s voltage regulator.

Hello Dave. Do You think, that it is possible to change the regulator without having to dismount the alternator? Best regards Peter

I have simillar problem but i have A3. Fault message is coming when i turn on some electrical things like heated rear window and after a while it dissapears to suddenly come on again when I turn something on. Do you think it will be the same issue as yours? Sorry for my english

what is the part number for that regulator? I have the same car - the dealership wants over $3,500 to fix this!

Does this method work for a 08 A5 3.2 qttr

Where u older the replacement part
