I joined the forum to seek advice from those in the know, my 2016 e89 2.0l has recently developed a screech when i start it up on a cold morning of which there have been many here in Scotland this last couple of months , i keep it in the garage but nevertheless it screeches when i switch the ignition on in the morning , it only happens first ignition of the day and only on cold mornings - so far.
Under the bonnet is a mystery to me , i love driving my Z4 but how it works is knowledge that i do not have.
Anyone have any ideas , the car was new 2016 its done forty six thousand miles.Thank you.
