There is a round plastic container near the left hand side between engine and mud guard. Unscrew the top and you will find a dipstick that shows correct fluid level. Use transmission oil sold at garages etc. The brake fluid container is on the same side near the radiator.

I m a locksmith and had the same problem

What you do is:

HOld The handle up while you turn the key to the opening direction, it will feel as though it may bend the key but it will not.

keep pulling the handle until the button pops up it works I did it

You will need to take it to somebody that has a scan tool or a OBD 2 or better scanner. I think ammco, kragen, or autozone will hook up a scan tool and turn it off for free. check it out

Hi, you dont say how much oil is in the body but if its a high miler some residue is normal as it seems to make its way up via the vent tube.This can be cleaned out with a good throttle body cleaner. But remove the body from the intake system first as you dont want to dose the engine with this stuff as it will cause the engine to over run if too much is fed into the intake. Let it dry out before re starting the car. Be carefull.

Do not believe it should stay on. Does it stay on even after you open the door and remove the key? Does it ever go out? Let me know and I'll try and help

Sounds like you have problems with a part called the valve body inside the transmission or other hydraulic control problems, i suspect you will need to overhaul the transmission to cure this.

You could have air in the clutch cylinder or there could be wear in your clutch master cylinder, You need to start by checking the fluid the the reservoir and then try bleeding the clutch, if this doesn't help then you will need a repalkcement master cylinder, It is recommended that you replace the slave cylinder at the same time as well as the flexible rubber hose.

Check fuel filter first. If OK, then check points, distributer and timing advance - or electronic ignition.

Because it's a BMW and as far as i'm concern, they are a heap of s**t. I've just been told today by a BMW dealership in Dublin that they want a €160 to look at the radio and between €900 - €1,200 to fix the radio. Never before I had a radio problem in my life until I bought the BMW. It has my heart broken and my pocket empty. Pure junk.

Yes but you're not going to gain that much HP for the effort. If you can locate a 3.5 (535 or 735 motor) you'll have better success in getting HP out of it. Ideally if you can locate 3.5 out of an M5 you'ld be stylin'

Computer needs to re-learn. it will take a few cycles before it goes back to normal operation. Drive it around, up & down hills, hi & low rpm & speeds, shut it down for a bit and start over again.
