AFAIK they're just normal vacuum solenoids - with the usual vac-dump ability.
So are you losing vacuum with them powered and are the vac hoses on the right stubs?
The EGR flow reading may be done by the MAF?
A P-code would help - tried reading it as EOBD?
Thanks for the reply
I think the Flow reading is done by the MAF it should read 200 ish, but is reading 400 ish (got my actia updated and reading it)
Still cant get any P code though although the lamp comes on the dash.
If I manualy (suck on the pipe!) close the butterfly I can get the reading to come down.
I have fitted one new solenoid, ( non Genuine) but it is still the same, apparently letting vacume straight through (to dump) and not pulling the valve shut.
Tried reading with EOBD, but still cant get any readings
Got a reading looking at it as a Pug 307 and got P0400 and P0485, but dont know wether to trust these codes or not.
The pipes are on as it was when it came in , no reason to think anyone else has altered them. there is a blue one and black one, both look as if they are going to the correct place. Just checked again, stub marked 'out' going to the butterfly, stub marked 'vac' is vacume in.
Should I be able to hear the solenoids click as they are powered? and do they run 12v, I could try them individually with my power probe.
