Danny Posted 6July, 2014 Report Share Posted 6July, 2014 Are you unlocking the car from the passenger door?. If so lock it again and unlock via drivers door. Might sound stupid but happened to me. Link to comment Share on other sites More sharing options...

firstone Posted 6July, 2014 Report Share Posted 6July, 2014 You could try a reset of the ecu by disconnecting the battery negative lead. Leave it 15 min or press the brake pedal to use the remaining charge in the vehicle. Reconnect. You will lose radio so have your code ready.

Carrera28 Posted 6July, 2014 Report Share Posted 6July, 2014 I feel your pain had a similar thing happen to me on Saturday night on a main street with everyone looking at the dickhead in his Porsche that didn't work Link to comment Share on other sites More sharing options...
sydr Posted 6July, 2014 Report Share Posted 6July, 2014 Gents, I refer you to another thread bemoaning the scarcity of 3.2 / early 911's. Never heard of this problem with them - does this explain their scarcity? Link to comment Share on other sites More sharing options...

Flatout Posted 7July, 2014 Report Share Posted 7July, 2014 When I bought my car, starting was not 100% on it. Cavaco said it was the alarm, so I binned the old one and fitted a new one. The alarm guy I used (who I've used for about 4 cars and 2 motorbikes) said most fitters don't understand Porsches well enough and stuff up the install. Car started perfect after I had the new alarm installed. PM me if you like & I'll give you his contact details, nice guy and he comes out to your house. Cheers.

I would appreciate his contact details. I think I should replace my older immobiliser/alarm as I only have one remote and if I loose it or it stops working, I am stuffed. I need someone who worked on 911 of this vintage Link to comment Share on other sites More sharing options...
