Hmm, I don't know whether thats true or not. At the end of the day its Bosch equip, not alfa. However I'm no expert so it may be right.
I have a similar prob at the minute. I've had two diagnostic tests on the car over the last fortnight.
Basically the car kangaroos when starting from cold, and uses loads of fuel 18mpg!!
The tests first revealed a faulty air flow meter and 'lambda sensor over maximum'.
They thought the lambda prob had been caused by the air flow fault so to make sure they reset both faults and told me to come back in one weeks time(save buying a air-flow meter for no reason!)
When I went back the air flow meter fault hadn't re-appeared, just the lambda fault!!
It said that the fault had happened at 7250rpm @ 2 degrees (Christ I never drive it that hard, not even when hot).
So again I've got to go back this week to see if the same prob has occured.
This is getting a pain in the arse, but luckly they only charged me once for the test.
Keep us informed how you get on Ricky, as I might have to go to a dealer as well at this rate!!! wink
