No valve stays shut /inoperative, plug disconnected at vacuum actuator so no vacuum to open it,So, suspect the valve removed completely, and some sort of tube put in its place, does this device then trick ECU into thinking it's still there?.
What was cost ?
Yep will probably copy your post about it to the letter ! Awaiting arrival of catchcan.get some right angle copper bends, they really help getting the catch can pipes going the correct direction.
Fitting behind headlight is a doddle.
It did not fix my oil problem, but halved it to one drip in about 500 miles.
and it reduced emissions at MOT, which was an unexpected bonus.
was hoping the combination of swirl flap delete/egr delete and cleaning of pipes /inlet manifold etc all combined might improve mpgYou won't find any appreciable difference in economy but you should notice a more responsive engine at lower revs. No waste of exhaust through the egr.
Worth a look in the fuel filler cap as all the tyre sizes should be listed there. Alternatively the manual should have the details of the winter tyre sizes which will be the narrowest ones availablewell my planned mpg check didn't go well, was in limp mode the whole journey(only good thing was the car still drove ok at a steady 65mph and didn't really struggle even up big hills as long as I wasn't forced to slow down by congestion before I hit them)
Also windscreen washers failed ,doh.
limp mode was caused by egr vacuum pipe coming apart at join(don't know why but cable tied vacuum pipe to nearby pipe) all driving fine no clouds of smoke on kickdown,
Washer was a pain, decided to swop washer reservoir with pumps from spare as my washer tank had hole in top and looke 20 yrs older,
washers still only dribbled, after testing all pipework ,turned out long pipe from bulkhead to washer pump was blocked, swapped from spare , washers now better than ever.
when I filled my original washer tank a while ago, I filled it with -10 or so screenwash so it would defrost screen in mornings when icy, when I swopped it out I noticed the water in it had what looked like small whispy pieces of gunk floating around, so the strong screen wash may have cleaned off 17yrs of build up on the inner walls of the reservoir??)
Oil catch tank arrived so that's next job , then back to fixing spare bumper at last.
Anyone know what is the narrowest rim/ tyre(for economy) with biggest profile (for comfort) that I could fit on my ml in exchange for my 275/55/17.
going to take out my headlight soon so will give it a goThat appears same size as the one I fitted. It will go behind headlight.
