Hi Eddie

What Ed is going on about is:

The way the diesel emission test stands at the moments your Merc has passed with flying colours and probably will do for the foreseeable future. VOSA deemed the current emission test to be adequate for Euro 5 and 6 because they just assumed that every vehicle presented would have a functioning DPF, they could not envisage that garages would actually remove an anti pollution devise

The amount of Soot Particulates permitted to enter the atmosphere for Euro 5 vehicle has been reduced dramatically, the fact that you have removed an anti pollution device means it no longer meets that Euro 5 standard. Or have you found a solution for reducing the soot output via a software update?

So as for Eds question, now that you are aware that removing an anti pollution device is illegal and invalidates the drivers insurance (UNLESS YOU DRIVE IT OFF ROAD) are you still going to remove them on Euro 5 and Euro 6 vehicles?

I am sure VOSA, Motor Trade Associations and the Environment Agencies would be interested in your views on this open forum.
