Looking for solutions to engine failure and loss of power in a 2022 Renault Master

Hello, of course, I know it. I had the same problem with my 2019 Renault Trafic and the symptoms sound similar to yours. In my case, the fault was actually the crankcase ventilation. It's apparently a common problem with diesel engines. The crankcase breather helps to let out the pressurized gases. If the part is defective, this can lead to the symptoms mentioned. I took my car to the garage back then. They just had to replace the defective part. Afterwards, the engine ran smoothly again and fuel consumption also went down. It's a serious matter in terms of size, but don't worry, it can be solved. Everything ran normally after the replacement. Hope this helps you a little. Don't drive yourself crazy, just take it to the workshop and have it checked. Good luck and I'll keep my fingers crossed for you!

Hey, thank you very much for your feedback. It's reassuring to hear that I'm not alone with my problem. And it's good to know that the whole thing can be solved and that I'm probably not facing a huge problem. I will probably go to the garage first and have it checked. Could you perhaps tell me how much it cost you to replace the crankcase ventilation system? And have there been any other incidents or news regarding your engine since the replacement? Thank you and best regards!

Hi, I'm glad I could help you. Regarding the cost: I spent around €360 to rectify the fault in the crankcase ventilation. Not exactly cheap, but hey, the engine ran like a kitten again afterwards. And to your second question: since the mechanic came, everything has been running smoothly again. No more jerks, no loss of power and consumption is also back to normal. So I can only recommend that you take care of it and then you'll probably have peace of mind for the time being. So, cheer up and off to the workshop! You can handle it. See you then and hang in there!

Moin, that sounds very promising! Thanks for the price information and for sharing your experience with me. Good to know that fixing the problem will lead to improvement in the long run. I've made an appointment for tomorrow at the garage to have it checked out. I'm hoping, luckily for me, that it's the same issue with my Renault and I can then drive again with peace of mind. Thank you again, you have really helped me and given me the courage to tackle this problem. Have a good day and see you next time. Take care!
