Hey, I had a similar problem with my 2013 Citroen C4. I'm definitely not a car expert, but have a bit of experience with this sort of thing. I had the same problem in my garage. In my case, the damaged cable on the electric changeover valve was to blame. I paid around 155 euros to fix it. But before you go to the garage, it would be helpful if you could provide some information about your car. Is it a gasoline or diesel? And can you give me the exact model number? With this information, I would be able to help you a little better.

(Translated from German)

Hey, thanks for your willingness to help! My DS4 is a gasoline engine and has already done 14401 kilometers. I haven't had any problems since the last service, so I'm a bit surprised that problems are suddenly cropping up now. I'll keep your idea about the electric changeover valve in mind when I go to the garage. Was that expensive fun for you or were the costs limited?

Hey, the 155 euros really included everything, parts and labor. So it's within reason, if you ask me. And yes, problems like this can take you by surprise overnight, just when you think everything is going great. It happened to me with my Citroen too. But don't let such things put you off. It's normal and just part of owning a car. I'll keep my fingers crossed that it's a similar case for you and that it's just as easy to fix. Please let me know how it goes. I would be really pleased to hear that I was able to help you!

Hey, thanks for the encouraging words and good advice. I feel a bit better prepared now. And 155 euros is really affordable. I hope it's the same for me and just as easy to fix in my case. I'll definitely keep you posted and let you know how it goes at the garage. Thanks again!
