Post by: topher on 30 August 2009, 09:55: try cleaning up the plug on the maf... from the testing i've done and swapping around various maf's that we had lying around the abs warning light seems to come on when the fault reported is "Signal too low" although the car still seems to run fine. Get a fault code reader on it and see what's what.

Post by: ipswich1.8t on 30 August 2009, 11:42: Well my engine emissions light has come as well now , so i'm guessing the maf is playing up .
Are they cleanable/fixable , or is it a new one ?

Post by: topher on 30 August 2009, 11:45: you can try removing it and blitzing it with carb cleaner.. but usually when they die that's the end of it. avoid the cheap ones on ebay

Post by: ipswich1.8t on 02 September 2009, 22:07: ok that sounds good , i've got a mate looking at it tomorrow lunch time but if he has no luck i'll be in touch .
The wierd thing is one of the lights has gone off , the one to do with the brakes ...but the engine managment one is still on . Is it just a question of removing the error code ???
Title: Re: warning light
Post by: ipswich1.8t on 03 September 2009, 15:31: Well i went to see my mate , he plugged in his loverly little snap on machine , and found 5 fault codes ..so he got rid of them which has cured the warning light and the car is now running a lot better .

He did notice that it's running a bit rich though and noticed that one of the temperature sensors is reading about 10-13 degrees lower than it should be , so he thinks the car is trying to compensate for this , so i have ordered a new sensor ..and we'll see if that cures the problem ....and my fuel consumption ...
