Check Motronic Engine Control Module (ECM) power supply relay -J271

The motronic Engine Control Module (ECM) power supply relay -J271- supplies voltage to the ignition coils with power output stages and the Engine Control Module (ECM) at pin 121. Disconnect voltage supply relay -2- below left cover at bulkhead.

Check fuse S10 (in fuse holder, position 10).

Note:

To remove the protective hood for the TT Roadster relay carrier, disengage at the bulkhead and swing downward. Disconnect additional harness connectors at Mass Air Flow (MAF) sensor, if necessary

Check Voltage between coil pak plug pins 1 and 4. should be approx. battery voltage (ignition on)
