Mokka's EGR Nightmare: Engine Stalling & Power Loss Issues

Hey there! I've got some experience with cars, and I had almost the exact same issue with my 2020 Vauxhall Crossland (similar platform to your Mokka). The symptoms you're describing match what I went through, it was indeed the EGR valve. Took it to my trusted workshop last summer, and they confirmed it was stuck. Ended up paying around 355€ for the replacement and labor. Fixed all the issues you mentioned, the stalling, rough idle, and that annoying power loss completely disappeared. What's your mileage and maintenance history? Also, have you scanned for error codes? This info would help confirm if we're dealing with the same problem. Hope this helps! Let me know if you need more details.

Hey! Thanks for sharing your experience. I'm at 49214 KM and just had my service done recently. Haven't scanned for codes yet, but your Crossland story sounds spot-on to what I'm experiencing. That price doesn't sound too bad if it sorts everything out. Think I'll get it checked at the workshop this week, rather fix it now than wait for it to get worse. Really appreciate the heads up about your repair experience!

Thanks for the update! Yeah, 49k km is about where I started having these issues with my Crossland too. Just to share, after I got mine fixed, it's been running like a charm for the past 18k km with zero problems. The repair was definitely worth every penny. Quick tip from my experience, when you take it to the workshop, ask them to clean the EGR valve passages while they're at it. My mechanic did this as part of the job, and I think it's helped prevent any new issues from popping up. By the way, since you mentioned you just had a service done, did you notice these problems before or after the service? Just curious because sometimes these symptoms can show up right after a service if something wasn't put back quite right. Either way, the EGR valve is still most likely your culprit based on what you're describing. Keep us posted on what the workshop finds! Always good to know what's going on with these cars.

Thanks so much for that extra advice! The problems actually started about two weeks before the service, but the mechanic didn't mention anything about the EGR valve during the service, maybe they were focused on the routine stuff. I'll definitely ask about cleaning those passages when I take it in, sounds like a smart preventive measure. I've booked it in for Thursday morning, and knowing your Crossland is still running great after the fix is really reassuring. I'll probably update this thread once I get the diagnosis and repair done, just in case someone else runs into the same issue. Really appreciate all your help and sharing your experience, it's made me feel a lot more confident about what I'm dealing with!
