Seeking Advice on Persistent Engine Issues in 2012 Volvo V50: Suspected Camshaft Sensor Failure

Hey, I can totally relate - I had a near-identical issue with my 2009 Volvo S40 a while ago which turned out to be the Camshaft Position Sensor (CPS). The behavior was exactly as you described; the engine light was glowing like a Christmas tree and the stalling, rough driving, low power, it was all there. Took it to my trusted garage and they were quick to identify the issue after running some diagnostics. Turned out, the sensor wheel on the camshaft was faulty. The CPS can give a lot of issues if it begins to fail and in my case, it had actually lost its capacity to deliver correct timing signals to the ECU. While it was not a day-and-night change post replacement, the drive got considerably smoother removing all the problem-like stalling, starting issues improved and power seemed to return. Apparently, it's fairly common in these high mileage Volvos. So jolly well might be your CPS, but I'd suggest getting a proper diagnostic run before jumping to conclusions. Best of luck with that, cheers!

Hey there, your experience sounds all too familiar with what I'm dealing with right now. I'm really hoping it's just the CPS going bad as you mentioned. Quick question for you though - do you recall how much you had to shell out for the fix? Just trying to get a ballpark so I can brace my wallet, you know? Also, since getting it repaired, have you noticed any other problems popping up down the line? Appreciate your input, cheers!

Hey, Yeah, I remember having the same thoughts on my mind - wondering if the wallet would survive the hit. Well, the repair on my ol' Volvo set me back by 695€. That covered diagnosing the problem and fixing the defective sensor wheel on the camshafts. Considering how hell-bent it was on turning every drive into an adrenaline-pumping adventure, I'd say it was a fair deal. And as for your other query, nope, zero issues since the mechanic worked his magic on it. The Camshaft sensor problem was definitely squashed - the car's running as sweet as ever since. Just remember, though, every car's different and things might not pan out exactly the same for you. Best of luck with the situation. Hope your Volvo bounces right back too! Cheers!

Hey! Thanks for the quick reply. €695, huh? That sounds fair for regaining peace of mind during drives. Your good experience post-repair definitely lessens my worries about this whole situation. I suppose the best course of action is to take her to a reliable mechanic and get that diagnostic run like you suggested. Fingers crossed it all turns out well, hey? Thanks again for your helpful info. Take care! Cheers!
