Need Help with Potential Central Fault Memory Lock Issue in 2018 Volvo V40

Hey there, Seems like you've got quite the pickle. Had pretty much the same headbanger with my 2016 Volvo S60, petrol engine too. Not a mechanic by any stretch, just a guy with a tad of car knowledge. Took it to my trusted garage, they found that one of the electronic control units was acting up, somewhat like your hunch about the central fault memory lock. The repair set me back a sweet 625 Euro, but it got things revving smoothly again. Just wondering though, did you manage to pull any specific codes? Knowing the exact issues or error codes could help me share more pinpoint advice based on my experience. Cheers!

Howdy! Your situation does ring a bell. That sneaky electronic control unit, eh? Well, for my darling V40, I haven't really dug up any specific codes yet. I honestly didn't expect to need them- definitely need to invest in a code reader soon. My latest service was done not too long ago, and I've racked up 124,438 KM on it so far. I'm gonna take it by the garage to see if they can pin down the problem and hopefully won't cost me an arm and a leg. Appreciate your input so far. Always good to learn from experiences. Will keep you updated once I have more info, friend!

Hey again, Ah, the infamous mystery of "fault stored with no codes". Feels like a ghost hunt, doesn't it? Definitely agreed on grabbing a code reader, it makes a world of difference; sort of like your personal cryptic translator for the car. I see we're somewhat similar in mileage as well. My S60 is sitting pretty at 131,000 KM. Brought up some, uh, "character building" experiences along the way. Let's hope neither of us have to go non-stop pit-stop any further, haha! Getting your high miler looked over by the pros sounds like a solid plan. Plus, approaching a garage with a bit of preliminary knowledge and suspicions might just land you a better deal, or at least a more transparent breakdown. Keep an eye out for anything dodgy with your ECU or that central fault memory lock. As I said, my issue resembled yours and that was the culprit. Could save you some bucks down the line. Good luck out there!

Hey, Sure does feel like a ghost hunt! Very solid point on the code reader. It's going to become my new best friend when it comes to decoding what my V40 is trying to tell me. "Character building" experiences is right. Here's a toast to no more pit-stops, in an ideal world. Fingers crossed! Your advice has already been super useful. I think having a bit of a clue beforehand always goes a mile when dealing with mechanics, if only so I can nod along like I actually know what they're talking about. Sounds like the ECU and the memory lock are not ones to take lightly. I'll double check on those. Thanks a million for the suggestions and sharing your experience. Will circle back with updates once my V40 gets checked out. Stay tuned, Cheers!
