Volkswagen Eos Diesel Problems

Instead of phoning VW's head office and talking to someone who couldn't possibly know what was wrong with your car having never seen it you would have saved a lot of time if you'd gone straight to the mechanic. Instead of trying to self-diagnose a problem as you did in assuming the warning light was indicating a problem with the particulate filter it's always best to go to someone qualified to be able to diagnose a problem and fix it.
