Check the exhaust side of your valve cover gasket for evidence of an oil leak. Burning synthetic oil tends to smell like hot plastic.

try new switch or motor

Hi,
I think that if the battery went completely flat the vehicle may have lost the security code, or the same can have happened if you did not follow the boost charge instructions when starting. If that has happened you'll need to have the unit re-encoded by a dealer. Keep in mind that starting a vehicle periodically is good but if you don't run it as well the battery will become exhausted and finally fail. The start up of any engine drains more power from the battery than any other operation. You need to start it and give it a run.

There are a number of switches that need to be closed in order for the motor to operate. In particular there's a microswitch in the hood just above the left-hand seat which makes sure the motor doesn't operate until the hood has been lifted slightly.

My hood stopped working and I found the cable to the microswitch had been cut by the hood mechanism. Replacing the cable solved the problem.

Check the small microswitch on the LH top raol at eye level.

NOPE NO SPECIAL TOOLS JUST REMOVE BRAKE PAD WEAR INDICATOR CONNECTOR.REMOVE THE CALIPER GUIDE BOLTS AND THE SPRING CLAMP.TURN UP THE CALIPER AND REMOVE THE BRAKE PADS.THE INNER PAD IS LOCATED WITH A SPRING IN THE PISTON.

You should have a 5 digit code, enter the code and have the key turned to on ( ignition position 2 )

AIRBAG IS A DEALERSHIP FIX.ONLY THING YOU CAN DO IS CHECK AIRBAG FUSE.IF OKAY.FAULT IN AIRBAG CONTROL UNIT.

cam shaft position sensor at front of engine on top, i ve done a few of them you need to replace it.

That sounds right to me.

abs warning light/traction control (if fitted)also front brake pads may need checking(min thickness 2mm)
otherwise its off to halifax.......

their is a control valve on the inlet manifold and this is faulty but i have no product knowledge to tell you what to change ,i am asumming its a fly by wire type on a vehicle of this age so it could be the sensor on the top of the throttle pedal as well or the motorised butterfly control on the inlet manifold

use the chassis rails/box section that run fore and aft under the car......

you should get a gun and go blow ya brains out, better off. car is waste of money!

is it possible a rodent has eaten through some of the wires?
or could be that the motors that control the seat and the top drew moisture and rusted. also, I would check the fuses for the malfunctioning items. as for the radio code, you'll probably have to contact the manufacturer

On the manual the fluid is "lifetime" BMW MTF LT-1, SOME models used ATF. There is a plate on the side of the transmission that will give what your particular model was filled with.

On the automatic the fluid type should be printed on the "type plate" on the side of the transmission

both are usually Dexronn III ATF, but please check your plate!!!

Check your dimmer switch. Over time dust and grime deposits develop in the switch hardware and cause additional resistance across the brightness settings available.

Replacement is a snap provided you have the right tools, the correct part and about 30 minutes of time available. Your local dealership should have it in stock.

Pry the small panel that encircles the switch, remove the switch, disconnect it. You may or may not have to reuse the switch knob (If you have to reuse it, it can be release by pressing the spring button on the back of the switch(if applicable)) Connect the new switch, mount it, replace the panel, you should be good to go.

Good Luck!
