Basically my car wont start. I try to turn the key and it just clicks once from the UCH. Been told by the garage that i need a new ECU UCH and key fob. So i spent £140 and bought all 3 matching. Fitted them today and its still doing the same thing. The red flashing. Light on the dash still flashed when the key is not in at a normal speed. Any suggestions? I need my car to work as im missing out on pay.
