Seat Arosa 1.0L rough idle problem

Asked by Jan 30, 2018 at 01:34 AM about the 2004 Seat Arosa 1.0 S

Question type: Maintenance & repair

My arosa idles around 500 which is causing it to stall at lights, i've tried
cleaning the throttle body and resetting ECU and this did nothing still idles at
500. I've also just noticed the water sensor may not be working properly as it
keeps dropping off to 0 when driving (brought a new one and installing it in a
few days). I'm not sure if this will solve my problem but its becoming very
annoying. I had a friend connect it up to a vag-com and he set the idle from
500 to 700 and i was getting no errors where as before it would come up as
miss firing, but it wouldn't store the setting for some reason. just wondering if
anyone has more of an insight to this. would be really grateful

Have you looked at changing the electronic ignition pack and plug's and leads, sounds like the coil pack could be on it's way out, if you change the pack, change the leads and plug's as well.
