there is a relay on the inner fender the ecu is in the back of the glove compartment
The DME relay is located under the bonnet in a fuse box below the windscreen.
Relay is located under the bonnet in a fuse box at the scuttle pannel.
1985 was a changeover year for the 944. Early cars (sometimes refered to as 1985.1, with three separate round guage pods in the dash) have the DME relay located on the relay board in the driver's footwell, under the dashboard. The DME relay is in position 2 of the relay board, second one from the left. Later series cars (1985.5) have the fuse and relay board under the hood, on the left hand side, just in front of the windshield. Open the box up and there should be a diagram on the inside of the lid.
Depending on Model Year. After 1998 thru 2005. BMW made the operation of a DME dependent on the electronic mating of the EWS unit under the Dash (Drivers Side). Therefore once the car was started (in the factory) it immediately burned in a rolling set of codes that was specific to that EWS unit into the DME. Permanently altering that DME to work only with that EWS unit. There a few companies that have been able to replace those chipsets to reburn the DME bmwdme.net ....However you cannot swap a DME from one BMW to another without replacing and re-matching the internal parts of the DME with your EWS. It just will not work.
DME is Distance Measuring Equipment. It is an electronic device located in an aircraft that can measure the distance between that aircraft's location and a point sending out a signal.

It's all electronic and controlled by the DME unit. There is no distributor and threfore no manually adjustable timing components.
check your DME relay and your crank and speed sensors on the back side of the bellhousing. look up Clarks Garage on google for how to bypass and test the DME and how to test your sensors.
the aux fan relay is located on the fan shroud on e46 vehicles. It is a rectangular box with wires going to a harness and two wires going to the fan motor. It is not a replaceable part and comes as part of the fan unit. It commonly goes defective and can be a cause of overheating. This despite that the fan motor test ok - it is not receiving the signal from the dme when car running.
yes
Only the 944S's used an actual ignition control module, and it was located on the fender under the coolant expansion tank. The other 944's and 924S's used the signals from the referance sensors to the DME and the DME controlled everything. The DME's are located: 82-85 - under the steering wheel. 85.5-91 under passengers kickpanel, pull back carpet (it's velcro'd in under the dash at the / ) remove 4 screws to remove the wood panel, remove 4 plastic screws to remove the metal piece that holds the DME in.
