That's not good bet she wants yours until you get it fixed haha. From what I remember they were progressive through the range I'll take some data tomorrow and post.
The wife's Beemer is a petrol so shouldn't show anything like 140CFM at idle, 25 to 30 CFM would be more realistic. I got a cheap MAF just to see if the problem went away. However it was still messing about for a while after fitting it. The air flow readings are more realistic now showing 30 CFM at idle and 220 CFM at 5K RPM off load. Investigation into the odd running will continue.Haha, I felt the same when I had a hire car (Astra SRI) couldn't wait to get back in a Freebie. How did it go with the MAF, did the replacement sort the issue? Really busy weekend, sorry for the late reply. Had both cars on the diag today and both MAF are are messed up, one is reading too high and the other is reading too low throughout the range. I've just ordered a Synergy 2a with pierburg for the project and a cheap one for the other (going to be sold as soon as I'm done with the project).
is it physically getting enough air passing through mafDoes anybody have any ideas as to what I can do next ? Still have both error codes that return after clearing. Have thus far cleaned the connectors and installed a new MAF with synergy. I've seen on searching that astras have this issue and is due to a faulty earth in the connector, could this be the problem? When I get a chance I'm going to test the connectors earth (pin 3 I think). Any ideas as to what this issue could be are most appreciated.
Thanks,
Will
