Hey there, appreciate the swift reply. Interesting, I hadn't considered the accelerator pedal module. So, here's the deal, no strange sounds from the engine, it's purely the shake at idle, the jerking when accelerating, and the ominous check engine light. The jerk is most pronounced during light-to-moderate acceleration, especially when climbing a bit of a gradient. I might mention, she's clocked 78203 KM on the odometer and her last service was about three months ago. The mechanic didn't mention anything alarming then but it looks like it's time for a quick revisit. Thanks again!

Hey, no problem at all! Well, your V50's symptoms sound a lot like what my S60 went through. The shaking and jerking could definitely indicate a potential issue with the accelerator pedal module, same as in my case. If the pedal module is failing or its electronics go awry, it might not communicate properly with your throttle valve. That would cause the jerking during acceleration and possibly the engine light too. But, don’t rule out other possible issues -- could be everything from faulty spark plugs to some fuel injection issue. Considering your car's mileage, it would also make sense to check the transmission and motor mounts. They wear out over time and could cause shaking while idling. My best suggestion is to take her back to the mechanic. Explain the symptoms as detailed as you can and it would be great if you could also mention the pedal module. Be sure to get your onboard diagnostics checked as well - that check engine light is kind of a general cry for help from your engine and the diagnostic testing will help pinpoint the problem. Good luck, hope it turns out to be a simple fix! Cheers!

Cheers for the thorough response. I'll definitely look into the accelerator pedal module with the mechanic and get the onboard diagnostics checked out. Hopefully, it isn't anything too major and can be sorted relatively easily. I appreciate you sharing your experience! Your insights were super helpful. I'll post an update once I've figured out the problem. Until then, safe driving everyone!

Hey, I've had a somewhat similar issue with my '02 Volvo S60. I've got some experience with cars but certainly no pro mechanic. Took my Volvo to the local garage when it started acting up. It was a bit of a hassle, but turned out to be a problem with the accelerator pedal module or some internal electronics. It cost me 265 Euro to get fixed but totally worth it, no more jerking or check engine light. Anyhow, could you share more details about your car? Like any odd sounds, when does it jerk the most? It'd help to narrow down the issue. Cheers!
