Vehicle now has 255,000 k,s on the clock and has never gone better also blows no smoke only on very hard acceleration oh
I also use 3.2 ml per litre fuel of TC-W3 oil in the fuel this OM642 engine is going to see a million k,s in my hands

Modern European diesels don't have egr valves they inject urea into the exhaust system to burn the soot Mercedes call it add blue and Citroen call it eolys fluid

If you like the WH and intend on keeping it get rid of the EGR and fit a provent and Kn panel use the GDE tune to switch of the EGR and remap the engine
you will be very happy not only that much better driveability and better economy
I would say my gde tune plus provent and kn,panel will be paid for by the time I do 300,000 k,s in fuel savings

Doc, where did you get the Wynns EGR.
