98 Tdi No Start, Flashing Glow Plug Light, Odd Fuse14 Problem Prior.

[kangie]

Hi All,

 

My 98 reg. Galaxy TDI Has on a few occations blown F14 (Diesel power supply relay fuse) fould i could force it to blow by traveling about 30mph and dipping clutch and accelerator together. (Got my big foot caught on pedal) - car instantly dies and F14 10A blown. (This seems very odd)

 

This happened yesterday but Fuse has not blown. Have checked All fuses even the hard to reach ones, Pins 23,45 & 68 of ECU are getting power when ignition on (so relay209 is good)

 

Question: Does anyone know whats between pin5 and 6 of the injector pump? - this is shown in the manual as possibly a coil but I have 12v going in to pin 5 (by bypassing power relay 209) but with ECU disconnected no voltage appears at pin 6

 

Turns over fine

Glowplug warning light flashes

dash sometimes beeps

Imob seems ok (no flashing door light)

 

Any Ideas??

 

Thanks

You keep referring to relay 209, the power supply relay is 109

This needs to supply a constant 12 volts to the engine ECU when cranking.

 

Flashing glow plug light means a fault has been stored, it could also mean you have a faulty brake light switch (are your brake lights working properly)

Fuse 14 blowing randomly could be down to chaffed/bare wiring, look around fuel pump area and behind instrument cluster for this.

If you still have the black colour 109 relay and not the newer grey one I would also change that aswell as the black ones have known issues with bad solder joints.

A single beep from the dash after cranking is low battery voltage
