A few days ago, my C220 CDi Sports Coupe failed its MOT on a few things, including its emissions - Exhaust emissions exceed manufacturer's specified limit [8.2.2.2(a)]. But note that there was only an advisory for 'Exhaust emits excessive smoke ... etc .' as not likely to obscure the vision of other road users.
I bought the car new in March 2002 and in its 22 years, it's been reliable & served me well. Obviously there have been issues, some of which were the result of poor work by technicians. Its now done 272,000 miles, is a little noisy but accelerates really well, returns 55+ mpg on a long run, and has not been costing too much to maintain (which is why I've kept it on).
One of the individuals I've consulted following the failure, thought it only just failed the emissions test, another thought the DPF was damaged. I do understand that if it is damaged, then owing to the age of the car and its mileage, its uneconomic to rectify it, so effectively game over![Frown :( :(](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f641.png)
Questions:
Is there any way of positively identifying a damaged DPF, short of physically dismantling it?
If it is not damaged, is there anything to be done that might reduce the emissions?
Thanks for any suggestions - even if it's to move on!
