Problems with irregular shifting and noises in the Citroen DS3

Hi, I had a similar problem with my 2012 Citroen C3, my experience with cars is limited but I have learned what I need to know to fix some problems. At my garage they explained to me that the fault was with the "wiring harness". They had to replace it and it cost me about 180 euros. I hope this helps you. Can you perhaps tell me how many kilometers your DS3 has run and whether you have had similar problems before? It might help us narrow down the cause.

Hello, my DS3 has 107757 KM on the speedometer. I haven't had similar problems before, this damage is really new to me. The wiring harness is an interesting theory, I hadn't thought of that yet. I'll check it out at my garage. Many thanks for the tip!

Hey, no problem, I'm happy to help. Of course, with over 100,000 km, there could also be normal signs of wear. I would definitely have the garage do a thorough check. The grinding and howling noise in particular could indicate other problems. In my case it was the wiring harness, but maybe it's something else in your case. Let us know what comes out of it. Good luck with your DS3!

Yes, that's true of course, age could also play a role. The workshop is definitely on the agenda. Thank you again for your help and I'll get back to you as soon as I know more. See you then and thanks again!
