Assistance for diesel particulate filter and reduced engine power in BMW X3 Diesel 2008

Hello dear community, I need your support. My BMW X3 Diesel from 2008 with 189,600 km on the odometer is causing me a bit of concern. The check engine light is on, the engine power is significantly reduced, the DPF regeneration seems to be failing, my exhaust smells rather strong and is louder than usual. The last few times at the mechanic have really hit the wallet, so I wanted to ask here if anyone has had similar experiences and could possibly fix their problem more cheaply. I suspect problems with the diesel particulate filter, the message 'Remaining distance low' is also displayed. I would be grateful for any tips!

Hey, my e91 gives 00452a fault regarding dpf fill level, I have to find a way to start the regeneration for dpf, but I either cant find the proper section in the carly or there is something else wrong since the regeneration will not start/turn on. On my previous car (audi) the regeneration started automaticly, but with this bmw 320 d 2011 it has not started for a long time. Kind regards, timo

I think if the ash content is already too high, the regeneration will no longer work, only clean it.

So, I just couldn't let it go. I assume that the BMW control unit has an approximate runtime of 170,000 km programmed for a DPF warning. I read out the DPF values with Carly and came up with an Ash mass of 25gr and a Soot mass of 15.73gr. All values are well within the normal range, only the warning "Remaining running time approx. 34,000km". I have now removed the DPF and flushed it thoroughly with water (not at high pressure, just first with a 1/2" hose and then again with a small Kärcher). Rusty water came out, which probably causes the small reddish ash balls. After only clear water came out, I reinstalled the DPF. I then used a Launch919E to swap a DPF and requested a regeneration. Before the trip the following values: Ash mass 0.53gr, Sootmass 36.00gr. During the regeneration Ash measured 0.53gr and Soot measured 3.22gr. After the ride (end of regeneration 20min) then Ash mass 0.53gr and Soot mass 27.01gr. So, the error messages are gone and the DPF is like new again. That gives hope, doesn't it? :-):-)

My BMW, I marked the failure 452A (last occurrence many kilometers ago), 4D4A, 480A (last occurrence few kilometers ago) and 4D03 (last occurrence many kilometers ago) and 41BB (last occurrence many kilometers ago), these days I have changed the exhaust gas backpressure sensor and I have cleaned the FAP in a specialized company, I would need to tell the car that I have cleaned or changed the FAP? it can be done with Carly?

Unfortunately, the new DPF cannot be leaned on with Carly. This is only possible with BMW equipment.

You can do the same with a Launch 919e. In fact, any independent workshop can do it.

When in a diagnostic report it says, example last occurrence 10000 km and at present, with 20000 km has not come out that error, does it mean that this error is not present at present? Or if it is?

If the error has been deleted and no longer occurs, the problem is probably no longer present.

The error appears but last occurred many kms ago and at present, with the current kms it does not appear.

Hello, Either something is blocking the regeneration or, more likely, the DPF is defective. What else can be tried is a "forced regeneration" with a diagnostic device.

Where can I have my 2012 x5d dpf cleaned in area code 93162 in the US?
