Fiat Petra DPF failure

Alright, I'm stumped! I've got a 2010 Fiat Petra, diesel engine, and it's been a champ until recently. Now, she's coughing up a storm – thick smoke when I try to accelerate, and feels like I'm towing a boat anchor! Engine light is on, of course. Could it be the dreaded DPF? I've heard horror stories. Is there anything I can check myself before I'm forced to sell a kidney to pay for repairs?

The conversation centers around a 2010 Fiat Petra experiencing thick smoke and reduced power, likely due to a Diesel Particulate Filter (DPF) failure. The symptoms include decreased fuel efficiency and an illuminated engine light. While a DPF cleaning might offer temporary relief, a full replacement is often necessary. A professional diagnosis is recommended to confirm the issue and check for any sensor faults.

Reduced engine power and smoke? That certainly sounds like it could be a DPF issue. Has your fuel efficiency also taken a hit? When was the last time the car had a proper vehicle inspection? A sensor fault might also be a contributing factor, masking the real problem.

Fuel efficiency is definitely worse, now that you mention it! The last vehicle inspection was maybe a year ago? Could a simple DPF cleaning do the trick, or are we talking about a full replacement? And how would I check for a sensor fault myself?

Given the mileage and symptoms, a defective diesel particulate filter is a strong possibility. Although DPF cleaning might help in the short run, it's unlikely to solve the problem permanently. I suggest a visit to a workshop for a proper diagnosis; they can read the error codes and test the sensors. Replacing the DPF is unfortunately often the only solution.

Thanks so much for the advice! Looks like I'm headed to the shop. The diagnosis came back, and it's exactly what you said: DPF is toast. Quoted 1550€ for the replacement. Ouch! But at least now I know. Appreciate the help!
