An elderly relative is about to buy a nearly new Ford diesel with a particulate filter.
Problem is he only does about 8k miles a year and all around town.
I did warn him that there is a potential problem with DPFs and short trips and was treated with disdain - "I have brought cars all my life and never had a problem".
So, do I just sit back and enjoy the schadenfreude when he gets a clogged filter and he gets a big bill or do I try to persuade him once more?
