What I um "think I know"... Likely wrong.
Early models did not have the 'valve' to prevent sinking so they would slowly drop when turned off. I think this came in about 1995 ?
Usual range of engines mirroring the 405/406. Later 1.8 were 16V to 'match' the 406. 2.0 in 16v form and in 8v turbo form (matching the 406SRI)
Derv units being the usual 1.9XUD / 1.9XUDT / 2.1XUDT11 then later the HDi in both 90 and 110 forms.
Early 'mechanical' HP box replaced with 'electronic' AL4 around 1998/1999 (this matches the 'change over' time for the 306 actually)
Early diesel auto's were with the N/A unit only (no turbo) but it was possible to get a later (98? possibly only with the AL4?) XUDT auto.
'Activa' only available over here with the 2.0 turbo 8v unit. Elsewhere the V6 was possible.
My Questions:
1. Was there such a thing as an HDi auto or was the "two pedal" option offered only with petrol engines and the XUD/XUDT units ?
2. Were V6's offered with a manual transmission ? Not that I'd want a 'five on the floor' stick with the big V6 though. The only reason for asking this is the 406 was freely available in saloon / estate / coupe form with either transmission. Auto was more popular however.
3. Were the V6's the later 'more poke' units ? I do not have specifics on this, suspect variable intake as everyone else does it. My V6 knowledge is very limited.
4. The nasty earlier tensioner on the V6 can be changed for the sensible spring loaded one I read if you are willing to replace the water pump for the later type ? This is true or you need to knock a 'chunk' off the later pump as well ? , This reminds me of the later TU petrols where you can force fit the 'auto' tensioner if you want.
5. Do they have to have the 'green' LHM or can they take the later (orange?) fluid as per the newer models ? There is no reason for asking this other than curiosity.
6. I'm assuming given its the 90 and 110 earlier HDi units (the good ones) there's no DPF either to be concerned about.
7. 'Activa' models, forgetting just 'our' market here, was there an auto offered ? I'm only asking this as I think the 2.0 turbo would be manual only to 'mirror' the 406 as the auto was 16v only. There was a changeover with these and later ones did not have the turbo unit at all but that's off topic here.
8. Haynes suggests that to remove the head from the XUD11 (2.1TD) you have to drop the whole lot out ( ! ) that can't be right surely ?
, I would of thought with some swearing and removal of mountings etc it would be possible in situ. Just curious.I did flick though the BOL (a later one) to get a bit of information but it sort of muddles things.
