Re: Limp home mode, red injection light
I had this problem towards the end of last summer and asked similar questions on the forum and kind people like those above pointed me towards the throttle potentiometer. I then got it plugged into a diagnostic computer, not at an alfa specialist, but a local garage I know and it also pointed towards the potentiometer.
I then spoke to a local specialist who was familar with the problem and said you could change but it is quite expensive and a pain to get to. It is in the drivers foot well, a small cylinder a bit like a large C battery. He said to check the connections around it and to try hitting it a couple of times (not too hard) with a hammer.
You have to be a bit of a contortionist to get to it but I managed it with my feet up by the passenger head rest.I checked the wiring by giving them a wiggle and gave the potentiometer a couple of taps with a spanner.
The problem hasn't occured since, which a result. Not necessarily recommending that is the best way to solve the problem but it seemed to work for me.
