hi all

i got a little problem on me van

2.5 tdi v reg 1999

vcds it today and it has come up with 17564 / p1156 manifold pressure sensor g71 - open short to ground(i think it said)

power data bus - missing message instruments 18058 p1650

also, the brake pad warning light is on (the sensor wires are twisted together on the rear and i cant find any wires on the front

the coolant level light is flashing (after about 30 secs it comes on) there is a beep as well

also the oil jug warning light starts to flash, think the beep sounds agaoin when this happens,

all at tickover

some time th eoil light doe snot come on but the coolant one always does,

whe i rev the engine the oil light comes on every time.

the rev counter sometimes does not work or is a bit erratic

i have doen soem searching on here but wondered if someone had the time to chuck in a few ideas

last thing,

i noticed a purple wire that has come out the back of the fuse box, its has a pin still attached so it looks like it has been pulled out of a plug (wether this is something to do wth my problems i am not sure.)

here is a pic of the wire and the lights that flash




thansk in advance

cheers

UPDATE

i have sorted the g71 problem,

traced a wire broken from the g71 loom down to the ecu (blue one)

spliced in another wire and that ran vcds, fault gone.

still got 'missing data message' on the intstruments

but ii now know thats down to the purple wire i have hanging out at the back of the fuse box

i have started another thread about that, as all i need to know is where that purple wire goes to

hopefully someone will know

cheers
