Hey all. Currently driving from Leeds back home to Dwvon and my red Restricted Performance triangle has appeared. I called a mechanic who suggested the passive DPF clearance, which ive done (currently letting the car chill out after holding 2500 revs for 30 mins) Keeping fingers crossed this is the issue. Has anyone else had this and if so, is the next 150 miles gonna break my lovely jag????
