Mokka's Mystery: Stalling Engine & Warning Light Drama

Thanks that's really helpful! Had the exact same symptoms with my Mokka. Good to know it wasn't just me dealing with those unusual stalls, proper annoying, wasn't it? I'm gonna get it checked out this week at the dealer you mentioned. Just curious, do you remember roughly how much you paid for the repair? Also, has everything been running smoothly since they fixed it? Always worried about these things coming back to haunt you later!

Hey again! Yep, totally get your concern! I'm happy to report that since getting it fixed at the dealer, my Astra's been running like a dream, no more of those frustrating stalls or starting issues. The repair set me back 365€, which included sorting out the defective sensor cable connection. Worth every penny if you ask me! It's been about six weeks now, and I haven't had a single problem with the water sensor. The warning light's stayed off too, which is always a good sign! I know what you mean about worrying about these things coming back, I was a bit paranoid at first, but the dealer did a proper job. Quick tip though, they told me to keep an eye on the connections and make sure they stay dry, especially during these wet months. Apparently, that helps prevent the same issue from happening again. Let me know how you get on with yours, always interested to hear if others have the same experience with their Vauxhalls!

Thanks for all the info! Just wanted to update you on what happened with my Mokka. Took it to the dealer last Thursday, you were spot on about the sensor issue! They found the same problem with water damage in the connector, but also noticed my fuel filter needed replacing. Ended up paying a bit more than you did, around 450€ for the whole job, but they threw in a complete system check which was decent of them. Got it back yesterday and it's running perfectly now, no more stalling or warning lights! Funny thing is, while I was waiting at the garage, another guy came in with the exact same problem on his Insignia. Must be a common Vauxhall thing! The mechanic was actually really good about explaining everything and showing me what was wrong. Way better than my old garage, glad I made the switch. Thanks again for the recommendation. Really helped me avoid what could've been a much bigger headache. I'll definitely keep an eye on those connections like you suggested, especially with all this rain we've been getting lately!

Hello everyone, We have a opel mokka diesel 1.6, 180 000 km. In 2021 at 150 000km: After shutting down the engine, either manually or via the eco shutdown, the engine is started again, it starts normally and we hear and knocking sound internally and the engine stops and immediately starts up again by itself. This several times in a row until suddenly the engine keeps running normally. We could have this 2 times in a week. After long investigation it turned out to be a broken mass flywheel. This has been replaced along with clutch disc, pressure group butée. Now, not 30 000 km later we have the same starting problems, but without knocking noise. Engine starts perfectly, but stalls after 2s. As many as 10x in a row. And suddenly it does keep running. 1 time in 20 this occurs, no error codes, cold or warm engine. Power is ok... I saw in the garage that there is some oil leaking between engine and gearbox, 2 drops. The seal was replaced in 2021. Who can help me? Regards

Hello PieterD, The engine stalling issue after startup could be due to fuel delivery problems, air supply restrictions, or sensor-related faults, such as the crankshaft or camshaft position sensors. Check the fuel system, clean the throttle body, inspect sensors for contamination. I would recommend taking your car to a professional mechanic for a thorough inspection. Please keep us updated on your progress. Do you have any other questions?

Hello, Thanks for the info. In the meantime, the dealer installed another fuel filter. We keep our fingers crossed.

Great to hear that, PieterD! Please keep us updated on how your Mokka performs with the new fuel filter. If the problem persists, it might be worth checking those sensors I mentioned earlier. Do you have any other questions or concerns?
