Electrical problems and warning light in the 2018 Opel Vivaro - Possible message error in the air conditioning system?

Moin mate, I had a similar problem with my 2015 Opel Vivaro. Kept having problems with electrical faults, just as you described, and for me it was ultimately the refrigeration shut-off valve that was faulty. There were always interruptions in the air conditioning and mysterious message errors until my mechanic finally found the fault. It was definitely a serious problem, as the valve is responsible for ensuring that the air conditioning system works properly. When you visit the garage, you should insist that they take a closer look at the refrigeration shut-off valve. Hope this helps you!

Hey buddy, thanks for the tip! That sounds like quite an adventure you went through with your Vivaro. If you don't mind me asking, how much did it end up costing you to replace that cold shut-off valve? And have you had any other problems since then, or is the car now running smoothly again?

(Translated from German)

Hey, no problem! Well, replacing the refrigeration shut-off valve actually cost me nothing and was done by the mechanic as a gesture of goodwill. And you wouldn't believe it, since then my air conditioning has been running perfectly and the annoying message error has also disappeared. The Vivaro is purring like a kitten again and there's no sign of any more problems. I hope it works just as smoothly for you!

Well then I'm relieved! Cool story and thanks for the advice! I also hope it goes just as well for me. I'll go straight to the mechanic on Monday and follow your advice. Keep your fingers crossed that the fault will be fixed and without high costs! Bye guys and have a nice weekend everyone!
