Hi Guys,
I have got Adblue deleted on my w205 from a Tuner and after a day I got the engine light on. After running diagnostics , I got this error code:
• Fault code P246309
The soot content of the diesel particulate filter is not OK. There is a component fault.
He said it's not related to the adblue delete but I highly doubt that. Can anyone of you confirm if that could be related and what should be my next steps please?
Thanks,
Anuj

Why don't you remove DPF and do DPF off in ECU?

on some MB models you need to remove DPF together with AdBlue to avoid future problems

problem is wrong solution, mostly done by automatic crappy programs like swiftec,davinci ...etc ....with proper manual solution where you actually know what you are doing and changing, there is ABSOLUTELY no problems with dpf or any other system...

I don't want to do the dpf off because that would fail the car annual MOT here in UK.
I also think it's something to do with the adblue solution but I am not sure.
Also, there is another theory - so I had the adblue warning(car won't start in xxx miles) before adblue delete and I drove the car for around 400-500 miles with adblue warning on. I guess regens don't happen with that warning and that might have blocked the dpf and now when the adblue warning is gone , ECU is picking up the dpf issue and now the dpf is too blocked that the regens not happening by itself and dpf needs to be physically cleaned first. do you guys think it's worth getting it physically cleaned or should I put back ecu to original and then do the adblue delete again with different solution?
What do you guys suggest?

Maybe you should have restarted ADBlue before writing ADBlue off file
