just wonder if anyone can help me with this lot: main point of interest for me is the dreaded needle valve wiring, im worried that i mightve shorted them together somehow, would this cause ecu failure? thanks. dan 1999 galaxy tdi AVG changed engine due to valve failure which mashed the piston, used all components form original engine, took some starting but eventually went but with serious lack of power, vagcom pulled up the faults listed below, tried various components which didnt solve, eventually found more than a fair share of vacuum pipe faults this weekend, ran for 20 miles no issues, changed temp sensor to try and cure short gate time of glow plugs (fans cut in for a second or 2, light on and straight off), i put the original injector back in (swapped to try and cure needle valve fault-no joy), went for a drive out and now the glow plug light flashes constantly after 30seconds of running, ive swapped and re-swapped injector and temp sensor but its just the same??? ive got close to 11v feed to pin 2 (injector wire block) with battery voltage well over 12v cant seem to see any loose or bad connections anywhere, could the ecu suffer damage if pins 11 and 12 (needle sensor) have shorted somewhere? any way of checking this circuit without removing ecu as its a chore to remove, am i right in thinking the needle valve solenoid works by feed from ecu which operates solenoid and the ecu measures the distortion in the return voltage caused by magnetic interference? does anyone know the typical or maximum return voltage to ecu? resistance thru both injectors was around 104-5 i read that this is within limits. oh and brake lights are working, but does this rule out pedal switch??? thanks. dan. heres the fault list: Chassis Type: 7M - VW Sharan Scan: 01,02,03,08,09,15,16,17,18,19,29,36,37,39,45,46,55 ,56 Address 01 ------------------------------------------------------- Controller: 028 906 021 JK Component: 1,9l R4 EDC G000SG 2019 Coding: 00002 Shop #: WSC 00021 5 Faults Found: 16989 - Internal Control Module: ROM Error P0605 - 35-10 - - - Intermittent 17958 - Charge Pressure: Control Deviation P1550 - 35-10 - - - Intermittent 17569 - Manifold Temp Sensor (G72): Open or Short to Plus P1161 - 35-00 - - 17978 - Engine Start Blocked by Immobilizer P1570 - 35-00 - - 17655 - Needle Lift Sensor (G80): Open or Short to Plus P1247 - 35-10 - - - Intermittent Readiness: N/A Address 03 ------------------------------------------------------- Controller: 1J0 907 379 G Component: ABS 20 IE CAN 0001 Coding: 12812 Shop #: WSC 00020 No fault code found.
