Xantia diesel turbo/ecu problem?   
1.9 TD Xantia 1996 ish. What's happening is that if I accelerate gently all 
is OK, if I put my foot down (not necessarily very hard) the car splutters 
like it's flooding until the revs reach 3k and black smoke issues forth, the 
once 3k revs are reached it takes of like a scalded cat.

I did have a similar problem 3 years ago when I bought it and this may have 
been due to a wastegate or something similar. The only reason I wonder 
whether it is that, is because in my quest to find why the aircon stopped 
working yesterday, I pulled the fuse to the ECU because it also goes to the 
A/C cut off relay.

Sounds more like diesel problem rather than electrics.

True, the HBOL says injector problems. But it came on very suddenly, i.e. 
yesterday it was fine and this morning it wasn't so I was wondering if the 
ECU had a master reset type thingy.

Sticky injectors, you can get them checked at a diesel specialists.

The ECU only controls pump timing and EGR.

For some reason it sounds like it is massivly overfuelling at low revs, but
without looking at the actual vehicle its virtually impossible to say for
definate.

However a *very* good starting point (sarcasm) would be to re-instate the
fuse and see if it is then back to normal!

I might be daft but I'm not that stupid. The fuse was pulled, examined
and replaced.

When you say replaced, do you mean replaced with a new one (i.e. it was 
previously blown), or just the old one (with nothing wrong with it) put back 
in?  If replaced with a new one due to the original being blown, it's 
entirely feasible that the same fault that caused the old fuse to blow could 
have blown the new one.

It wasn't blown nor did I expect it to be. It was just one other thing
to check when the air con didn't work. Lets not go down this route, I
pulled the fuse because it powered the aircon cutout relay as well as
the ECU. All I wanted to know was whether this could cause the ECU to
reset to a "get you home" setting.

Does it even have an ECU? Earlier Xant Ds didn't, and I think that was 
around the change-over era.

Does it have the keypad immobiliser?

There's a circuit board in a plastic box just behind the driver's side
headlight.

Yes

Furry muff. Definitely after the point where the lump gained an ECU, then.

But, no, I can't see that the default settings (I don't think it's a 
"learning" ECU, anyway) would cause the problems you're having. I think 
it's more fundamental.

Ok thanks. It's booked in to the garage on Thursday unless I can crack
the problem before then.

ECU on an XUD9 engine - you've got to be joking.
It's an old tech indirect injection engine using either a Bosch or Girling
mechanical diesel pump.

If you are talking about a 2.0 HDi then that's a different matter.

Tis true, well sorta, the later immobilzier equiped XUDT's had a unit on the
pump and another which controls the immobilizer and also the pump timing and
EGR.

Its solid state, and more a logic controller rather than a computer that
responds to sensors and calculates something.

Wrong... It's certainly an old tech indirect injection lump, but later ones 
did indeed use an electronic pump with ECU.

The owners manual shows a fuse marked ECU and there is a PCB behind the
headlight which sort of looks big enough to be that kind of thing. But
the owners manual does cover a few varieties of the car.

At least the fuse descriptins in the owner's manual seem to agree with
reality, the HBoL fuse descriptions don't tally at all. No how, no way.

The 2.0l HDi engine had common rail. The 1.9l XUD9 had/has a mechanical
pump.
