AUDI A3 _BMN engine (2007) - HELP

I didn't chemically clean the DPF , noting comes out of it no dust.

I’m impressed you did that. Most forum goers aren’t that savvy.

Greg Roles spent a few hours with a Karcher, pushing the ash back out of the core, then drying it in the oven before putting it back in.

So as I understood it, the ash/soot doesn’t just fall out, it needs to be pushed out

To keep this simple, I know lots of you guys looked at the youtube videos but when I took the DPF off , I could see through the cells.
Anyway , Im gone past the DPF itself. Looking into combination of sensors again.

Cheers

Your ECU thinks your DPF is blocked.

Do a forced regen

you may need to reset the dpf loading

I had exactly the same issue.
