Hey, really appreciate you sharing your experience, it's spot on with what I'm facing with my S40. I'm definitely gonna have my mechanic get a good look at the DPF. Out of curiosity, do you remember how much the repair set you back? And has anything else cropped up related to the same issue since the repair?

Hey! Glad to know my experience resonated! As for the repair update on the Diesel particulate filter, yep, that little adventure did cost me a pretty penny, around 1550€ to be exact. They had to go in-depth to fix the internal defect of the DPF. But hey, since this grand expedition to the mechanics, I've had no problems related to that Diesel particulate filter at all. No more black smoke, no more guzzling fuel like a thirsty camel, and my Volvo's been running smoother than ever. Knock on wood, it seems like fixing that DPF defect did the trick!

Cheers for sharing all that! That does sound like a costly escapade but it's relieving to hear that your V70's been running well post the repair. Seems like my next stop is the mechanic's. Hoping for a similar outcome with my S40 too, fingers crossed. Your words have definitely eased some of the anxiety. Appreciate your help! Time to hit the road.

Hey there! Had a near similar experience with my 2011 Volvo V70 . Black smoke, excessive fuel consumption, the whole lot. The prickly issue was indeed in the DPF. It failed to regenerate properly, ya' see. Now, not to spook ya, but this situation can get nasty if ignored. The mechanic team I found dove deeper into it last time. Turns out, the Diesel Particulate Filter was packed internally with soot, becoming defective. They had to clean it thoroughly and reset the system. Afterward, the regeneration process kicked back in properly and the problems eased up. Now the ride's smooth as butter. So, you might wanna dive into that DPF and check it out. Best of luck!
