Hello all,
i know this is an old topic but any help would be gladly apreciated.
I drive a 2008 Jaguar XF 2.7 diesel, for the last 3 weeks i had the restricted performance amber light going on, mostly when i start the car in the morning or when slowing down. I started by changing the battery (it was 4 years old), the car drove fine for 2 days then back in RP mode. My mechanic scanned the car and it’s coming up P140-21A - Exhaust recirculation sensor C-circuit low. He says that on the live data he sees both Egr working normally so he says there is the possibility that changing it will not cure the problem. But also doesn’t have any other solutions.
Any advice or people that have been in my shoes? I’m getting really frustrated by this problem.
Many thanks!
