Hi there, it's my first time on so please be gentle!
My Mrs has the 1.9 cdti 150 XP. The egr valve was replaced 6 months ago & car serviced 4 months ago. The spanner warning light stays lit for up to 5 minutes when started from cold then goes off & the max mpg we've had is 38 combined. Any ideas?
Also, during the really cold weather, there's been a fairly loud knocking for a second or two low down in the engine when started from cold?
Thanks in advance
