Audi A4 Diesel (2006) does not start: Possible key and hall sensor problems
(Translated from German)
Summary of the thread
A 2006 Audi A4 Diesel is experiencing starting issues, a warning light on the speedometer, and potential key problems. The suspected cause is a faulty Hall sensor in the ignition key, which may require replacing the entire lock set. Another possibility mentioned is a defective slide-in shaft, which was a similar issue in a 2008 Audi A6. The recommended solution is to have the car checked at a garage to diagnose and address the problem promptly to prevent further damage.

Hey, thanks for your quick reply. My last inspection was at 211456 km and I haven't added 1000 km since then. There have been no new problems or warnings since then either. I'll have the slide-in shaft checked, thanks for the tip! Did you have it repaired at an Audi workshop or was it just a simple garage?

Hey, no problem! My Audi actually had a nearby Audi service center where I had it fixed. I have to say, they did a really good job. Anyway, in your case, it almost sounds like the Hall sensor you mentioned might be the problem. If that's the case, you'll probably need to have the entire lock set replaced. That can be a bit expensive, but it's important to get it fixed before it causes even more damage. But don't let me put you off, this is just my guess based on my experience. It would be best to have it checked at a garage of your choice. Let me know if you have any more questions!

That's exactly what I was afraid of. Thank you for sharing your experiences with me. Your advice was very helpful and clarified a lot about my possible problem and how to solve it. I will definitely have it checked at a garage and point out the Hall sensor. It's good to know these things before you go to the garage. You're right, I should get it fixed quickly before it causes serious damage. Thanks again!

Hi, I'm not a car mechanic, but I do have a bit of experience with cars. I had a similar problem with my 2008 Audi A6 diesel and the symptoms were almost identical. It turned out that the slide-in shaft was defective. That cost me 290 euros. I would suggest having this checked by a garage. My garage diagnosed the problem quite quickly and fixed it. Could you perhaps tell me more about your car? That would help me understand the problem better and perhaps help you further.
Hi Juwag92, I showed your idea to my garage and it actually worked for me. I had the same problem with an A6 from 2009. thx!
