When the Glow Plug Light comes on, the ECU stores information about the condition that has caused it to come on. A qualified mechanic who has a code reader that is suited to your particular make and model of vehicle can retrieve this information, and then make a diagnosis of the problem and recommend a course of action. 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). To remove the protective hood for the TT Roadster relay Merthyr Tydfil, United Kingdom. Oct 20, 2015. #3. Glow plugs are only used for starting the car. They are not a performance item hence why no loss of power. The glow plug light flashing and your fault code go hand in hand. The light is used to indicate the fault. Swap the switch and I'm 99% certain it will cure your problem the switch is .
