plug it in to a diagnostic machine to see the fault

i believe its under the hood against the fire wall possibly the drivers side. there should be a boxed in area the fuses are inside

sounds as the barrel is broken or malfunctioning. you will need to remove the plastic cowling to gain full access to the ignition barrel which may give you a clearer picture of whats actually wrong. sometimes the steering lock tab gets jammed preventing full key turn

remove rear seat and look for plastic big round cap

No! I believe this is the cap for your automatic transmision, do not put engine oil in here. The fill for the engine should be on top along the rockercover. If the you can find the dipstick for the transmission, the oil should be a slight red/pink colour. The dipstick for engine oil, the oil on the stickwill be dark brown to black colour!

not sure which relay box you have in your engine compartment, but here is one for 89 BMWs where the pump relay is at the top.

To test the relay, please see my tip at http://www.fixya.com/cars/r6022358-relay_check . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info. A typical BMW fuel pump circuit is shown below:

Hi


Thanks for using FixYa. To start with check the Speed Sensor on the front and rear. Usually the issue is with the rear speed sensor which can be replaced easily and will cost you around $25-$40. There is a sensor at the top of the rear differential for the ABS system. When the ABS sensor on the diff goes bad the Speedo no longer will work, the odometer stops recording mileage and both brake and ABS light comes on. You also loose O/D or "Lock-up" in the torque converter. The sensor is inexpensive and can be changed in about 30 mins.
Replace rear differential speed sensor as follows:
a) Remove parking brake cable bracket (1/2" socket)
b) Remove speed sensor bolt (9/16" deep socket)
c) Remove metal speed sensor cover
d) Remove speed sensor from rear differential housing (use channel lock pliers, twist gently back and forth while applying upward pressure. Once the speed sensor has a small gap between it and the rear differential housing, insert a flat-blade screwdriver and gently apply upward pressure while gently twisting speed sensor back and forth.
e) Disconnect speed sensor from speed sensor cable
f) Lubricate new sensor with WD-40, insert into rear differential housing. It will NOT go in all the way by hand, so do NOT force it nor hit it with anything made out of metal.
g) Replace metal speed sensor cover
h) Insert speed sensor bolt and tighten LIGHTLY until a small amount of pressure is felt. Tap speed sensor with rubber hammer until it pops into housing. Finish tightening of speed sensor bolt.
i) Replace brake cable bracket, replace 1/2" nut and tighten
j) Disconnect positive battery cable for 2 minutes, reconnect positive battery cable




Please do accept the solution if the issue is resolved or else revert for further assistance.



Thanks

The blower motor relay is located in behind the climate control center mounted to the ac box.The window relays are located in the power distribution center under the hood number k-5 and k-7.

sounds like the clutch is out to me ......

the problem is in your dash. you are going to have to replace the battery in the instrument panel.
these will control the opening and closing of your thermostat. i bet that you are having issues with your tach and possibly fuel consumption. once you do this you are set.

try the coolant pump to test it take the bottom house of the radiator of ( messy coolant leaks a lot ) turn engine on if it just trikles out with no pressure its the coolant pump another sign which worked on my golf, turn your heating on if it does not stay hot or is not very hot then its your pump .right bk to let me now

If you still need info email me and I'll send you the specific pages of service manual. [email protected]
