If the unit detects that there's a CD in the unit it thinks it should turn on. The other thing it might be doing is getting disconnected and reconnected ( the fuse box is well known for dirty connections ) with out removing the fuses, you can roll( turn the fuse) in it's holder to make a better connection. the key switch can do this too as you hang too many keys on it. Try removing the extra keys off the car key and see in the problem goes away.

you check and see if you have a fuel pump reset switch on the car not sure about this car but sounds like the problem

vehiclw won't turn over to start

Sounds like you need a new shop. If they just replaced the clutch the sound is most likely from an improper install. If you had warning lights or check engine lights I would agree it's the sensor but at this point it sounds like they didn't get the clutch in correctly or the throw out bearing and the more you drive it the worse it is going to get. They just don't want to drop the Tranny and admit they messed up without getting paid.

Hello,

Thanks for using FixYa.

I suggest that you bring your car back to the dealership. They might not have reset your Bimmer's OBD system.

I said last time, pull upward with great force! Holds a lot, but no screws!

Warning!
pulling the knob head then there is when it is then that you can knock - out to the chin, really!

This car is more species on the battery type!
Depends on type and size of the engine and your comfortable trim inside the car!
Difference in the battery is already different to the A / C condition or not! I'm sorry that I am more reply for you with this query.

pull up and use excessive force! it just struck not bolted

have come across some weird and wonderful noises in my time ??but??i would need to have a drive of the car to know what the noise is sorry if iam of no help but for this you will need to use a local mechanic .

There are three different amp that you may use for the z4...520 cold cranking amp (650 cranking amps), 600 cold cranking amps (750 cranking amps) or 730 cold cranking amps (912 cranking amps). Hope this helps.

Hey- I have the exact same problem with my Z4 although its a 06 as opposed to an 04. I took it to the shop and was told it was break dust covering the break sensors. They removed my rear calipers and rotors, cleaned and greased the brakes. So far I havent had the sound again. Doesnt it feel so weird to be driving around with the top down on a nice day then slow down at a red light and be accosted with such a horrible sound like that? It drove me absolutely nuts. It went from a light sound only when I was barely accelerating (like trying to find a parking spot) to a bit of a scratchy metal sound which is why I think the problem may apply to you as well.

On a side note, I am also told by a friend of mine who is also a bimmer guy that it might be due to the brake pads vibrating back and forth inside the brake caliper. He suggests checking out a $2 investment in a product called Plastilube which will stop the noise. I did a quick search and you can purchase it by going to:

I brought a z4 in last year into Canada. A dealer has to set the computer up. You can't do yourself. Took about 10 min. and cost me 50 bucks by a Denver dealer.

Hi, On the E85, MY03 - 09 a seperate fuel filter is absent. Unlike the E36/E46 which has an inline filter and is reaplceable as part of the maintenance items, the E85 does not have this 'feature'. The fuel filter is an integral part of the intank fuel pump [ which i believe is like the strainer.

In order to change the ff the entire pump assembly has to be replaced. On the safer side this is one of those items best left to be done by the dealer.

Regards Sean/elytics

have you had the alternator or fan belt checked as they will squeel when they are loose and you accelerate.
This may not be the problem but it is a cheap fit if it is the problem.
hope this has helped

upon finding a favorite station simply press and hold a station selection button is for 15 seconds. That will record that frequency at the button you just programmed

If you have the owners manual, that should tell you eveything that needs to be done at 50K.
