Hi all
I'm new to the Z4, having picked one up today.
Its a 2.2 2004
It has nav and radio with the pop up display. The radio turns on, but no sound comes out. There are no steering wheel controls, so I can't mute it.
Any ideas please?

Do you have the higher spec system with an amp in the boot adjacent to the battery?

Pass. I will go and check and get back to you. Z4s are an unknown to me atm!

I’m willing to bet you will find water damage on the amp which has fried it
Pop it out for a look

I can see evidence of water ingress above the battery…

You need to sort the water ingress first, otherwise it’s £200-250 wasted

Thanks for all the help. Is water ingress from the boot seal, or is it from the roof?

Most likely your light seals in the boot but check all options out

Thanks all.
On separate note, its going for an MOT tomorrow, so fingers crossed.

Also- if you have water in the boot you may also have it in the car… worth checking before it fries your airbag modules
Check floor under the carpet for dampness both sides!
