Right all. I took it to my garage and explained. They had it for the day. They removed the filter and drilled 5 large holes in it then refitted. I picked it up but the fault was still there. Antipollution and clean diesel filter ! BUT, 2 days later both faults cleared themselves. This was 2 weeks ago and I couldn't be happier. It cost me £40 that's all so very relieved :-D Thanks for all the help people well chuffed !!
