Hi all,
There might be something already in here but here goes.
2003 TD4, runs ok, not using a lot of fuel the only problem is it cut out sometimes when I come to a stop, don't notice sometimes, steering goes heavy etc etc so no major things before it cuts out. Starts OK and drives like normal. Sometimes when it idles it revs up and down then settles. I know it's a odd one.
Had new fuel pump and filter, new injectors, serviced regularly.
other than that drives OK.
Any ideas?
Also how easy is it to change oil on rear IRD where prop shaft connects?

Have you done the usual MAP / MAF Tests??? try disconnecting the sensor.

IRD - info attached from RAVE Manual.

Thanks for the info, the seal I was asking about was the one on the IRD where prop shaft goes in. is it a simple job?

Ah..... sorry... you missed out the word "seal" - it looked like you didn't know how to change the oil.

to be honest, I haven't done one, but - i ASSUME..... that its a prop off job, and remove the 5 nuts, pulling the IRD Prop Hub assembly off the IRD.
Let me see if it explains it in the RAVE Manual.

Seal - pinion gear
$%41.29.04
Remove
1. Remove pinion housing.
CAUTION: Before dismantling the pinion
housing, measure the turning torque on
existing bearings.
2. Attach pinion housing to suitable mounting
plate and secure mounting plate in vice.
3. Check pinion torque to turn figure.
4. Reference mark pinion flange and pinion shaft
for assembly purposes.
5. Restrain pinion flange using LRT-51-003.
6. Remove and discard nut.
7. Position pinion housing onto press, fit suitable
adaptor on end of pinion shaft, press pinion
shaft from drive flange and housing.
8. Remove and discard collapsible spacer.
9. Using a suitable lever, remove pinion oil seal.
CAUTION: Take care to avoid damage to oil
seal recess.
10. Remove pinion bearing inner race.
Refit
1. Clean pinion shaft, drive flange and housing.
2. Clean oil seal recess.
3. Lubricate and fit bearing to pinion housing.
4. Lubricate new seal.
5. Using a suitable adapter, press seal into
housing.
CAUTION: Oil seal must be flush with end of
pinion housing.
6. Assemble pinion to housing using new
collapsible spacer.
7. Lightly lubricate drive flange splines with
Molybdenum Disulphide grease.
8. Align pinion to drive flange reference marks
and press flange onto pinion shaft until a 2 mm
clearance exists in bearings.
9. Fit pinion assembly to mounting plate and
secure in vice.
10. Fit new pinion nut, hold pinion drive flange
using LRT-51-003 and tighten pinion nut to 150
Nm (111 lbf.ft).
11. Check pinion torque to turn figure.
NOTE: Figure for new bearings is 180 to 200
Ncm.
If original bearing figure is above 20 to 30 Ncm
and below new bearing figure, set to figure
recorded.
If original bearing is below 20 Ncm set to 20 to
30 Ncm.
12. If turning torque is too low, carefully tighten nut
and recheck reading. If turning torque is too
high, pinion assembly will have to be
dismantled and a new collapsible spacer fitted.
Reassemble using new nut and recheck turning
torque.
13. Check drive flange run-out using a Dial Test
Indicator (DTI).
CAUTION: The drive flange run-out should
not exceed 0.05 mm.
14. Remove pinion housing from vice and
mounting plate.

hope this makes the job much clearer.!!

do not for get to change your crankcase filter.
