Hi, been a 2003 Clo Dci 80 owner for 3 years 70mpg and reliable 103K

Just bought a 2005 C5 1.6 Hdi, thats doing 60mpg !! best ride ever and Ive had Jags !!

things to do on the C5, full oil flush service (Forte) and blank the EGR. Other forum has said not to map it so will take their advice, was going to add 20hp
Fit LED DRL's to update the front

Hello and welcome.

From what I know, a removal of the oil feed banjo/micro filter to the Turbo, cleaning of the sump (remove) & pick up......and cut in HALF the oil change intervals would maybe be better jobs before removing/blanking of the EGR.

Blanking the EGR will throw EM Faults with that engine without a re-map.

Apparently not on the C5, but in the ford & Volvo it does

Welcome!
