update for tonight
thanks for keeping repling
as you have been saying EGR valve
I was never 100% happy about the pin in the solenoid
I also removed the solenoid and cleaned that with carb cleaner and with WD40 - so the pin clicked in and out
i just thought the pin moved just a little bit and held back with a spring and then the solenoid extended and the spring snapped back
Well I have looked at an article here
http://www.saab.zwart-hoekstra.net/...content&view=article&id=94&Itemid=102&lang=en
, I thought I would have the EGR valve off again (as i now can do that on and off in about 20mins)
and the pin did not move
So i used a pair of pliers and it pulled out - but was very sticky - a bit of carb cleaner and electrical cleaner and i got it a lot freer, to the point where it would drop out as i moved up and down - so I thought i had it fixed
went out for a drive and the car was great , responsive again at low revs - so I know before it was not right - 32 miles later and having a really nice drive . i turned the car off - waited for 3-4mins and when i turned back on again - no faults - but it was not the same drive another 12 miles and had a P0400 reading but no fault light , but the car is just not the same
so it has to be that solenoid, i will take it out again tomorrow , and decide if i want to break open over the weekend - or soak all day in carb cleaner and really give it a clean
and then if not order a new one, shame you cannot just buy the solenoid ......
thanks for staying with me on this - all you advice and help keeps me on track , and i'm sure will get to the bottom of this - like i did on the zafira, which was a clogged up lever on the vacuum pipe and that took a few goes of wd40 to get going
