Hi guys, thanks very much for your replies. I took The Beast for a run up the A303 to clean out his pipes and although the warning sign didn't disappear, it certainly lost some of the sluggishness.
Being a bit of a fusser, I decided I didn't want to risk running it until the dealer could sort it on 5 July in case things got worse so I contacted a local general garage with a good reputation and they were able to look at it at short notice. The had it for the day yesterday and took it out for a long run to enable regen. Not sure what they did differently, but it worked! 😍
Apparently, according to them, these DPF filters are becoming a real pain. It seems luck if the draw whether you have an issue although, undoubtedly, my recent short trips contributed to the issue.
I love my Sportbrake but clearly, my driving needs don't really justify a Diesel engine but when I bought it new, it was the only fuel option.
Oh well, guess I'll have to buy a petrol F-Pace after all.
I really appreciate your support and guidance. What a great forum. 😊
PS I'm not sure what the bill will be for the regen. They said they would invoice me so I'll keep you posted. Hopefully, cheaper than a new filter.
