td5 rough running, power loss, black smoke
Pantelis Giamarellos
Just a small note to advise you of a problem we were able to solve and which
may be of interest to those of you who drive a TD5.
A fellow member's car has developed serious rough running problem (from
tickover to high rpm), significant power loss (fifth gear was out of
question when inclines had to be dealt with, car could not start to drive on
second gear and had to be revved to 1200 rpm so as to drive on first gear
and LOTS of black smoke on almost rpm when the accelerator pedal was pressed
even slightly.
The problem has eventually been traced to the connectors between the
injectors loom (the one inside the cylinder head cover) and the external
part leading to the ECU.
It was not oil related but apparently someone had tried to remove it by
pulling the external plug from the wires which had resulted in damaging one
of the wires. More precisely the wire corresponding to the third injector
which was showing a "No3 injector" fault of the diagnostic. Further
investigation on the nature of the fault was showing that the diagnostic
could recognise the "No 3 injector" but as the "No 1" one!!!!
We have removed the protective covering of the external side of the loom,
traced the problematic wire, re-fitted the pins, cleaned both plugs, tested
the continuity on both looms and refitted everything.
The problem is now sorted.
Total cost 92 Euros including VAT charged for one hour of labor at an
authorised dealership.
Hope this helps.
Take care everybody

Don't talk to me about rough running/power loss TD5's. Mine has
80,000 miles on the clock.
I think I mentioned the blown injector seal that I had the other
month. Poor starting, loud whining "air" purging noises from the fuel
pump etc and £313 bill to replace all five seals, injector loom and
front cam seal.
Week before last it started playing up again. Started OK, no fuel
pump whinng, just lack of power and rough. Cause, fuel pump
knackered, motor not running, apparently the injectors can draw some
fuel through the system. £315 bill for new fuel pump... Maybe all the
air purging etc with the blown injector seal wore it out?
Last week I'd just done a "spirited" join of a main road and taken
the engine up to just over 3,000 rpm (my normal driving style is
<3000rpm). Within a 1/4 mile I became aware that the gear lever was
waggling about a lot and there was a tappety sound. 1/2 mile later
going through roadworks I noticed lack of power and really loud
rattley tappety noise (thought it might be a hydralic demolition
hammer in the roadworks but couldn't see anything). Found some where
to stop, yep expensive sounding rattle from the top end. Get
recovered and the cause is a siezed injector, ie the pushrod was
staying down allowing the rocker arm to rattle against it. £544 bill
for new injector. Maybe having to draw fuel rather than have it
delivered under pressure pushed this injector to far?
The fecking thing better not throw another wobbly for a very long
time!
Just before the fuel pump died I'd spent another £550 on a set of
tyres, I want to get me monies worth out of them.

The big problem my spannerman has noticed is injectors dropping to bits,
totally wrecking the engine, he's done 15 in a year.

Eeek, keep your voice down the car is only just the other side of a
door!
My spannerman said they had never seen a seized one before. But they
were in the process of changing another but that was on a works
vehicle and the rough running/lack of power had been ignored for a
while (they drove it 'till it stoppped) and had probably been leaking
diesel for a long time, thus had burnt a hole in the top the piston.
