I have a vectra '01 2.0dti. The EM light comes on intermittently, when the light is on I have loss of power. Had memoryread came up with 2 faults, tdc sensor(replaced) and EGR valve. Any ideas to help would be appreciated
it will be on the inlet manifold,an egr valve's job is to push exhaust gas into the induction system,partly to reburn unused fuel,partly to keep engine temp down,id try blanking it off their a pain in the ass.
you can't blank the dti egr valves off as it brings the eml on as far as i know.
you could try cleaning the egr valve which is bolted to the top of the inlet manifold as it will be all gunked up i suspect,it would also be an idea to clean up the boost pressure sensor which is bolted to the right of the egr valve and you could clean up the swirl chamber too which is under the inlet cover,your better off taking the lot off to stop as much gunk going into the engine.
thanks guys, bit more for u. i have cleand the egr on top of the inlet manifold,witch has one vaccum pip going to if(if i hav the right part)the valve it self was full of crud,wene i loose power the dash light comes on,so any other suggestions please.
the swirl valves i thought were a.k.a butterfly valves as far as i know,and they are under the cover of the inlet manifold which your egr valve was bolted too,they open and close with vacuum too,the vacuum for this is on the right hand end of the inlet manifold down the side,the boost pressure/manifold pressure sensor is also on the right hand side on the top of the inlet manifold,its held in with one torx bolt and it has a plug connector on it .
i think erroneusbogz is on about the boost solinoid valves as they have been called here http://cgi.ebay.co.uk/vauxhall-vect...14&_trkparms=72:1301|66:2|65:12|39:1|240:1318
