SpaceTourer power loss and smoke

Hi, I'm having trouble with my 2020 Citroen SpaceTourer diesel. It's got about 152501 km on the clock. Recently, the warning light came on, and I've noticed a significant loss of power. Also, there's quite a bit of smoke when I accelerate, and a really strong exhaust smell. I've checked the basics, like fluid levels, but I'm not really sure where to start with something like this. Any ideas?

Sounds familiar! I had something similar happen with my SpaceTourer. I reckon it could be a DPF issue. Are you doing a lot of short journeys? That can clog them up pretty quickly. Does it feel like the car is holding back, like it's got a sock in its mouth?

Yeah, mostly short trips around town. So, a DPF issue, huh? Is there anything I can check myself, or am I better off taking it to a garage? What exactly was wrong with yours?

Well, short trips are DPF killers! There isn't much you can do yourself without the right tools. It could be a faulty sensor messing with the readings. Mine turned out to be the exhaust back pressure sensor – was giving false readings, so the car wasn't doing DPF regeneration properly. Honestly, save yourself the headache and get it checked by a pro. They'll hook it up to diagnostics and pinpoint the problem quickly.

Thanks for the advice! I took it to the workshop, and you were spot on. It was indeed the exhaust back pressure sensor. Cost me 245€ to replace, but the van's running like new again. Really appreciate the help!
