Title: 2.5 TD EGR Valve
Post by: flymofred on 10 September 2009, 18:13:47

Am I right in assuming the EGR valve on this car is the part that the EGR pipe bolts to at the front of the inlet manifold. In my ongoing attempt to improve the appalling mpg on this car is it worth taking it off and cleaning it, if so what is a good cleaning agent. Assuming that the valve is where I think it is where does the little rubber hose go and why is this area dripping oil?

Thank You

blocking egr on td will hit mpg a bit - diesels use egr a lot to help with cruising mpg

thanks for the replies best mpg 33 using cruise control + driving like an old lady. I am looking forward to the 'how to' will that appear in the maintenance guide? i don't quite understand where stuff goes, for example this post seems not to be any where. I had to use 'search' to find it again it was only posted ' 18.23 today yet some stuff floats around for days?????  :-/

33mpg sounds rightish in an auto. If thats unchipped, that sounds even better :y

Bit low if its a manual though.

Cruise is NOT the most economical way to drive ;)

33mpg is what my 3 TD auto estates have done & do.
I once got 38 by keeping under 70mph.
Real figs , not MID.
I ran out last week after 518mls Mid said range 36, even tho its usualy fairly accurate.
