Interesting- a bit of thinking outside the box

Mr Muscle did a brilliant job on cleaning up my varibale valve turbo on my mk4 golf. Re your DPF, it may have cleaned it but, why was it not cleaning itself is the question. If it fills up again and doesn't burn off when at the set limit there's an underlying issue. What you've done is a good idea and certainly novel but you really need to follow-up with an immediate investigation of why it was full and not self regulating.

Its very foamy , accidentally you can damage turbo compressor wheel
