Thanks so much, sorted, I didn’t even know there was a filter in there.

Really grateful for the help thanks.

Thanks for reply it’s 1995 diesel and I haven’t got anything to read codes.

Hi I am desperate for help my bongo will start but will not rev higher than 1200 revs, this started whilst driving it started to judder and then the harder you press the accelerator the slower it went.
Any ideas would appreciated.
