Turbo Diesel injector pump leaking at throttle shaft
 

Just started today... based on a bit of googling it looks like there's an
O-ring on the shaft that can be replaced... has anyone attempted this ?
Anyone got an exploded drawing for the pump ? Bentley doesn't cover the
pump assembly much.

thanks in advance,

Vince

Turbo Diesel injector pump leaking at throttle shaft
 

There's a Bosch service manual for just the pump. The throttle shaft
seal can be replaced, be careful pulling the shaft off as it has a lot
of splines and things won't work right if you put it back on in the
wrong orientation. You might check the vwdiesel.net forums for
technical info on the pump.
