Dpf and engine light problem.

Hello my friend has a problem with his dpf.. Both the engine light and dpf light is on and he cant drive over 90km/h. He has replaced both the sensor and the dpf. Both lights went off but after a few km it came back on. It just wont go away. Can it be a clogged exhaust system or does anyone now what it can be? The fault code is P2463 and it comes back after a few km even after they are removed..

Can you post a picture of your engine, we have two versions in Australia and they are both different to the US one. Also is it turbo or non turbo.

When you don't post the year and model and mileage, it is shooting in the dark to say the least, take it to a qualified dealer for service.

I'd try to have a manual regen done before replacing the DPF. There was a time I thought my DPF was shot. That was 50K miles ago, and I am at 182K miles now.

Do you own a shop or something? With scopes, fancy scan tools, and all?

If not... Take it in. The dealer can diagnose the issue much faster than anyone on this forum. I'd say 90% of the problems people have on this forums are all solved by a dealer. The remaining 10% are just simply sensor replacements.

Well dealers here want 100$ just to look at it, and i have obd tools and i have fixed this kind of problems before. It was at a dealer before the replacements but they did just delete the fault codes as i did. But it came back again and again so we called them and they said we should replace the sensor and the filtre and so we did. But now no one knows a ****. Troubles with dpfs is a common problem but this ones tricky.

Unfortunately, it seems like taking it to the dealer may be the only real option here. Personally, I would never have replaced the DPF without first trying a manual regen. Seems like one or more sensors are giving false readings.

Yeah, it sounds logical. Thanks everyone for giving their thoughts!
