Hey, thanks for your help. So, my Mokka has 117520 km on it, last service was just recently. Other than that, I've noticed that the engine sometimes rattles a bit, especially in cold weather. And the smell of gasoline is quite strong, especially at idle. Hope that helps. I'll give the fuel pressure regulator a try, thanks again for the tip!

Hey, I think it could really be the fuel pressure regulator. It almost sounds as if the fuel is not getting into the engine properly. I also had this rattling in the engine and the strong smell of gasoline that you describe. Try changing it and see if the symptoms improve. But don't forget, even if it runs better afterwards, have the car thoroughly checked again at the garage to make sure that there are no other problems. In my experience, it's always better to tackle such things straight away before they get bigger. Have a safe journey and take care!

Hello, thank you for the quick reply. The additional symptoms you mentioned make the fuel pressure regulator even more likely as the cause. I will definitely have this checked and replaced at the garage and hope that the symptoms will improve afterwards. Your advice to have the car thoroughly checked again afterwards makes perfect sense. Sometimes there are several things going on at the same time and you only concentrate on the most obvious problem. I'll take your tips to heart. Hopefully everything will work out the way I want it to and I won't have to put any more money into the car. Thank you, you've really helped me a lot!

Hello, I have an Opel Zafira Tourer 1.4 LPG.
The check engine light comes on together with ESP.
Error read out and misfire on 1 or more cylinders" otherwise no symptoms. Workshop has changed everything to do with the ignition. Problem persists.
Hi Paul25, if the ignition system has been thoroughly checked and the problem persists, it might be worth looking into the fuel system. Misfires can be caused by a faulty fuel injector or even a clogged one. Also, consider checking the compression in the cylinders. If there's a significant difference, it could lead to misfires. Please keep us updated on your progress. Do you have any other symptoms or information that might help us narrow down the problem?

Check the condition of the spark plugs and ignition coils, as they can sometimes cause misfires even if they appear to be functioning. If they are fine, inspect the wiring and connectors for any signs of damage or corrosion. Let us know how it goes or if you have any further questions!

Hi, I had a similar problem with my 2014 Opel Corsa, I only have some experience with cars so I took it to my favorite garage. They replaced my fuel pressure regulator and it cost me 250.0 euros. It points to a problem with the fuel pressure regulator if the engine runs rough, power drops, takes a long time to start cold, occasionally won't start and just stalls even at idle. Have you noticed any additional symptoms that could help us narrow down the problem?
