Thread: Problem on cold start up's (300Tdi D1)

I remember reading somewhere that Tdi's should'nt need the glow plugs at all to start in general Australian conditions. I guess they (glow plugs cables) are very easy to get at and dis-connect to see if they are actually making any difference.

Ever cleaned out the fuel sedimentor?
Fuel filter needs changing?
Air leak on fuel lines,
Check elbows on to of fuel sender for corrosion/perforation
Check for air leak on filter bleed screw
Check condition of injector bleed pipes for air leaks or just replace
Next could be fuel pump faulty, may not be upto job and injector pump is doing the pumping
You shouldn't need to worry about glow plugs, 300tdi's should start easily without using them at all

Hope this gives you a start ( no pun intended )

Forget about the glow plugs, even in winter a 300TDi should start fine without them.

Your problem is more than likely to do with the fuel supply. Clean what you can, check the pipes & see what you can find.

my problem ended up being the starter....in these condtions the car would take a couple of turns to urn over. since changing the starter in the same cold/damp conditions I dont even get to finish the turn of the key and the car has alsready fired.

I'm still yet to test whether it has cured my long journey stopping and not starting again problem that I was having....but i'm guessing it probably has

Even though the Tdi really needs no glowing, they still need to crank over at a good speed. As DB has found the starter replacement helped, but also firstly check the earthing to the engine, run an extra earth cable from the battery directly to the engine block, and then try it.

My other standard response to Tdi cold starting issues is timing. Even a few degrees retarded will prevent cold starts, glow plugs or not. When was the last timing belt done?

Good point... Forgot the crank speed/earth.

Mine was an earth problem and a buggered battery . But mine still won't start on a cold morning without glowing it first ... doesn't need glowing for the rest of the day tho .

thought mine was an earthing probem...changed earth strap live strap and everything...even changed the relay to the glow plug as was also suggested that this can hang up not allowing the circuit to complete.

the car slowly got worse and worse....to the point where it wasn't just starting in the cold but starting it when it was hot

after all that ended up being the starter
