Hi all not sure if this is in the right forum but this is the issue, i bought a draper tool for ressetting the service lights on bmw, i bought this as i assumed it would work alot better than the cheap chinese ones on ebay. so i plugged it in followed the directions it came with but with no joy, here is how i did it
1. plugged in tool with ignition and tool off in the 20 pin adapter under the bonnet
2.switched ignition on and set the tool to inspection
3.switched tool on and gave it a few seconds and switched it off
4. turned ignition off and removed tool and replaced cap
but the light under inspection is supposed to illuminate and then go off but it didnt the tool powered up but nothing else. I have also tried it on the other setting for oil but no joy there either. I have an e36 compact 1.9 sport with both a port inside under the dash and the 20 pin under the bonnet for which the connections look fine. any ideas anyone?
