Restricted Performance (red)

[Sam Taylor]

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????

Did red rp disappeared? If not I would advise against driving it. Could be anything

I had a warning that my DPF was full and the car was in "limp" mode. (3 litre F Pace Sport, 45000 miles).

After a DPF doctor check, the Data and codes came in at only 20% full, which should have been cleared by a forced DPF clearance run.  After a clean out and resetting everything, the car ran for another few hundred miles and went red again showing DPF problem and into "limp" mode. 

A second visit again showed less than 15% soot in the system, but this guy suggested a look at the throttle box, as this can jam open affecting the turb, as the internal plastic housing can deform due to heat.

Sure enough, the butterfly valve was jammed open. It's a common problem apparently.

I had a new throttle box and exhaust pressure sensor installed at Jagutek near Ely, and 3 months and 2000 miles on everything is OK..... 

£600 for a new box and sensor versus £2000+ for a new DPF unit......!!!! Thank you DPF Doctor number 2 !!!!

Yes, sticky throttle flap is common and can be fixed by filing it slightly, so it doesn't stick anything. did that in mine. 

Although never heard of sticky flap throttle and dtc for dpf full as result...
