hi, i've had a bit of an ongoing problem with my caddy for just over a week.the oil light comes on and the power drops slightly,but very intermitant and random.
i borrowed a friends vag com today and brought this up:

01170 fuel injection duration sensor (g175)
29/10 short to ground intermitant.

i've had a look around the pump at wires,plugs etc and cant seem to find anything.
any ideas or anything i can check?im pretty new to dielsels.

Sounds a little odd.  How long does the light stay on for ?  And how long does the power drop for ?

Did the same errors re-occur after you cleared them ?

Maybe check on voltage when this happens - VW control units can do all sorts of weird things when they receive too high (or too low) a voltage (often caused by faulty alternator or regulator).
