Hi there,
i am new to this forum
looks like i have an issue, No power to the glow plugs. when i first start the car in the morning it will start after about 8 secs turning the engine
found out that no power to the glow plugs, for the rest of the day is fine
relay gets power to the 3 pins with key in position2 but not giving it to the glow plugs
85, 86, and 30 they have current 87 goes to the glow plugs no(relay doesn't click, of curse as there is no ground )
checked manually the relay and works ok
no errors via vcds
if i give electricity tho the glow plugs directly from the battery for 3 secs car starts within 1-2 secs
also the light in the dashboard for the glow plugs when turn key to position 2 illuminates for 1-2 secs
question is
were is the 40 or 50 amps fuse? the car is sharan 2005 auy engine 1.9 pd tdi
what other components are playing role to activate the relay as i get electricity on 85,86 and 30 pins and if i cut the 85 pin and short, relay side, to earth then relay clicks and electricity sent to the glow plugs
so i think 85 pin should something ground it and is not
were is the temp.sensor which is responsible for the glow plugs, outside temp sensor ok(i see the readings in the ac panel , on the radiator(3 pins) ok
if anyone can provide a diagram of the glow plugs-ecu- wiring etc with full detail description.............would highly appropriate it
any advice pls
millions of thanks
