Dagger Posted July 17, 2017 Author Share Posted July 17, 2017 Turned out to be the most common problem with MK1's The coil pack Thanks everyone Quote Link to comment Share on other sites More sharing options...
Phil21185 Posted July 18, 2017 Share Posted July 18, 2017 You were lucky. Coil pack failure on my mk1 killed the ecu. I had to spend £400 on a new resistor... And I even had to have a second brand new coil pack fitted or the place the garage sent the ecu to wouldn't guarantee it... Glad you got it sorted. 1 Quote Link to comment Share on other sites More sharing options...
