My fiesta van (1.8 diesel, non turbo) recently failed the MOT on a number of things, including emissions. It is sitting at 3.5 (with a pass at 2.5). I have now cleared all the other items with the exception of emissions.
I have run injector cleaner through the tank at regular intervals, but the emissions are refusing to budge.
Are there any simple solutions? (Last resort is to visit a diesel specialist, but as I run this on a shoestring any excessive spend will outweigh the value of the car!)
Cheers
Peter
