Car was not running properly

Hi Volker.Yes being a 1975 car mine does not have a separate ballast resistor.I will have to do some digging to try and find there model numbers.but I can tell you I drove to Germany with the blue Beru coil in place in 2015 with no problems although at that stage I was running Luminition ignition was not long after that trip and 20 years started to give problems hence my switch to Petronix.Thank you Nigel

Hi Volker.The Beru coil now on the car is ZS106 .0040100106.I also have a new Bosch 0221119027 K12V .I forgot to mention I have a while ago fitted rear LED side lights + boot and bonnet interior lights + some instrument lights .These are quility lights that run cool.and from a UK specialist.However there is a slight flickering of the rear side lights and front lights ( which have the original type bulbs) when the engine is running ! The rev counter still does its jumping with all the light off. Regards Nigel

Hi Nigel,

Bosch gnition coil 0221119027 is wrong for your car. You should have 0221119021 or ...016 . The 027 needs a power resistor in BMW 1500-2000 series. I cannot comment more as I can currently not open my microfiches and check. I recommend that you verify Bosch Classic  what would be correct coild for you.

Hi Volker Thank you for that..I will try and checkRegards Nigel

Hi Volker.Would the coil number you gave still apply as unlike the factory 3.0 si I'm running Petronix ignition.?

Yes
