2009 Volvo C70 Diesel Experiencing Reduced Power, Lower Fuel Economy, Unusual Engine Behavior, and Strong Exhaust Odor

Hey there! Sounds like we're sailing in the same boat! I drive a 2006 Volvo S60 Diesel that tussled with similar problems not too long ago. Check engine light blinking, car shaking like it's doing a dance, and yeah, that rotten exhaust smell - check on all that. Swung it around to the garage and, after some poking around, turned out the root of the issue was defective injectors. The mechanics had a good go at them and had to replace all the injector units. It wasn't a minor issue by any means, my friend. The injectors, they're basically the heart of the engine's fuel system. So when they play up, you bet the engine's going to cough and splutter. The repair work to replace the injectors was quite a bit of wrench-turning. They had to remove some parts for access, replace the faulty ones, and put everything back together, which took a decent amount of time. In the end, though, my S60 was back to her old self, purring like a kitten with no more check engine light, no shakes, and a much less pungent exhaust. Keep your chin up, it might sound like a biggie but it's solvable. Get it checked out quick, good luck!

Hey, thanks for sharing your experience! That sounds pretty spot on to what I'm dealing with. Replacing all the injectors does sound like it takes a fair bit of work, but if it gets my C70 back in shape, it's definitely worth it. Out of curiosity, do you remember roughly how much the fixing up cost you? And since the repair, have you encountered any other issues or has the old girl been in top-notch condition? Appreciate any extra details you can throw in!

Hey! My pleasure, always good to share a car recovery story, isn't it? Now on to your question about the repair cost. The defective injectors work set me back around 515€. Yes, it's a bit of a price tag, but trust me, seeing my old dame back in her prime was worth every penny. And since the peaky injectors got swapped out, it has been smooth sailing! The moment she rolled out from the garage, I could tell a world of difference. The engine roughness? Gone. Like magic. Nothing but smooth revs and easy running since then. So, sounds like your C70's got a similar fix with those injectors. I'd say go for it, get her patched up. You'll be grinning ear to ear when she is back to her sweet, smooth self again. Cheering you on from here!

Really appreciate all the info you've provided! The price does seem a bit steep, but as you said, you can't put a price on peace of mind, can you? What really encourages me is to hear about the smooth performance of your ride since the fix. That's exactly what I'm looking forward to with my own C70. I'll definitely take this up with my mechanic, fingers crossed for similar results. Thanks for the morale boost as well! Sure needed it, and I'll let you know how it comes along. Cheers!
