the coil pack has been changed

those might still have points, change and adjust them along witha new condenser :)

need lots more details in order to help. Where are you? I'm in Scotland and have done lots to these cars. My sister had an 80 sport , I had an 80 Quatro , fantastic cars.

i agree with sabre7801 but couldnt rate him yet,could be many things,but they dont have points like someone else has said.done a rebuild project on my 83 ur quattro turbo.

Check your crank position sensor.

have you tryed changing the leads is there no spark from any plug?

has it got a 3 wire plug to the distributor? if so it will be marked up + o - turn ignition on, pull coil lead off distributor and hold 1cm away from engine block, pull the plug off the distributor and put a split pin into the terminal marked o then tap this on the engine block. The coil lead should spark, if it does change the hall sensor in the distributor (may have to buy complete distributor).
