Hi,
I have had my Z4 for 3.5 years, bought from a member, and never had any serious issues with it
However, late last year it would start intermittently?!?!
I turn the key, all the lights on the dashboard turn on, stereo and heater work fine, but the car doesn't start at all, no noise from the engine at all.
I turn it off, and then try and again, and sometimes it then starts fine.
Sometimes I have to wait a while before it will actually start.
And other times, it will start fine 1st time.
I took it to my Indy, and he said it was probably the Ignition switch. He replaced that, and it was then starting ok every time.
But a few weeks later, I started having the same issue again.
The Indy said it was probably a faulty ignition switch. He ordered a new one and replaced it free of charge, and it was then starting ok every time.
BUT....a few weeks later, I have started having the same issue again!
I went back to the Indy, who has said the problem must be something else and he will have to diagnose the fault on the car. He said all 3 ignition switches were original BMW parts, so it doesn't make sense.
He said one thing I could try is to use the other key I have, as there may be a chance that the coding in my 1st key is playing up, and if so then this will stop the car from starting.
I will try this from tonight when I get home (if the car starts that is!).
I only replaced the battery a couple of years ago.
I did a search on here, and one person disconnected the battery overnight and this seemed to help fix the problem...at least there were no further posts to indicate it had happened again. Should I try this?
Does anyone have any ideas please as to what the problem may be, to help me get back to enjoying my Z4 and not be worried about it not starting every time I go to use it?
