Probably just a quick one guys... I've recently bought a 98 1.8T Sport (great car!). The Air Con / blower is coming on for 3-4 seconds and then going off again for the same amount of time, regardless of if I have it on climate set temp, LO, HIGH, AC on or AC off. Does anyone have any ideas why this is? I think the AC needs re-gasing (no problem, mate with machine), would this help?
