986 won't start normally and then doesn't turn off
 

Hi Guy's,

My first post and already an issue with my Boxter S from 99...

All dashboard lights, headlight, radio, Fan and other electrial system are ok, except alarm. When I turn the key to start the engine everything dies and no sound from the engine/starter. So it doesn't start normally.

When taking out the fuse for motormanagement a few times I can start the engine and then it runs fine.

Then it does NOT turn off anymore via the ignition key, unless I use the Clutch in a high gear with handbrake on. However all dashlight keep on burning until I disconnect the battery. When connecting the battery all dahslight are back on again.. Also the Alarm doens't jump in.

Yesterday I replaced the ignition switch completly as I already had some problems with that, that works fine now.

Any ideas,

Ronald

using a dvom ,what is the batt. voltage [key off] then engine running? batt age ?

Check the key chip. You'd be surprised how often it goes out.

will hook up another batt tomorrow and will use the spare key to see for any differents. Car keeps on thinking that the key is still in the ignition somehow...give it a night sleep first...

Very well could be the ignition switch -- when it starts to fail all sorts of weird electrical issues. It is cheap to replace on your own using the equivalent Audi part number.

+1 on checking the ignition switch.
