Re: 2.1td vs 2.0hdi pros & cons
Actually andy (spider) your spot on... thr hdi Did replce the 110 2.1 initially hence why all early hdi cars are 110 models... so any S and T reg 406 or Xantia Will be 110 bhp.. it wasnt till later in 1999 that the xud was fully laid to rest and replaced by the 90bhp...
as for the Xm.. by 1998 production was winding down and it wasnt worth the production cost of modifying the xm electronically to take the hdi so it was left to use up the remaining 2.1 engines... thats my thearey anyway on the xm bit... shame really it missed a cracking engine...

Re: 2.1td vs 2.0hdi pros & cons
Xac, yes mine is a 110.
Dickie, once I get above 1500 rpm it pulls smoothly in fact even below 1500 it pulls more smoothly but not as smooth as the XM, the vibration is at its worst at exactly 1500 rpm. It feels amost as though the extra weight of the XM is damping the vibration.
Chris, I very rarely drive mine above 2000 rpm, except possibly on the motorway.

Re: 2.1td vs 2.0hdi pros & cons
Blimey peter.. that wont do the cat on the 110 any good if its still fitted. it will soon get blocked up.. you need to have a hard good blast to clear the exhaust out or else theres a smoke test fail at mot time.. the 2.2 certainly wont like low revs either...
still shows what a feather foot can achive.. id prefer a few less mpg and a clear exhaust...

I was referring to the XM Paul, but I dont drive the Hdi's very fast - makes them use fuel

Re: 2.1td vs 2.0hdi pros & cons
You might like to try disconnecting/blocking off the EGR in that case.Peter.N. wrote: Chris, I very rarely drive mine above 2000 rpm, except possibly on the motorway.

Even if you try it by pulling the vacuum pipe off the EGR and plugging the pipe up, that should give the same effect and im sure you will notice it more willing at lower revs.

Re: 2.1td vs 2.0hdi pros & cons
Thanks Chris. Its not so much its willingness as its roughness, its probably perfectly allright but after driving 2.1 XMs almost exclusively for over 15 years I'm probably a bit over sensitive. I am perfectly happy with the way the 406 performs (except for the ride) in fact its very nice to drive, it just seems to be a bit uncouth at very low revs. Most people probably don't drive at as low revs as me but in the XM you can, which I think is what gives it its economy.

Re: 2.1td vs 2.0hdi pros & cons
The 110 HDi is better than the 2.1 providing it works as it should. Faulty solenoid valves, vacuum leaks and MAFs (and new fake MAFs) can rob the HDi of it's best characteristics. The HDi can be costly to fix if it's a fuel related issue but with a good remap they are great to drive.
However you can't get a HDi XM....

Re: 2.1td vs 2.0hdi pros & cons
Ah but Peter, PSA design the cars around the engines, and these 8v DW and XUD engines have the mounts all in IDENTICAL places, so only one engine bay needs to be pressed for all engine options! And as the HDi replaced the 2.1, it will go in!

Oh, right Paul, so you just have the electrics to sort out then Certainly sounds easier than making a Perkins fit in a Morris/Vauxhall/Ford.

Re: 2.1td vs 2.0hdi pros & cons
And for original Questions asked... what can go wrong with HDi's???
Well, little does when you consider HOW much is under the bonnet. Its on a Par with a Petrol injection engine in theroy... The injectors are electronically triggered, theres an ECU, a crank sensor, a Cam sensor, fuel pressure sensor and pressure regulator. Fuel Temp Sensor, Mas Air flow sensor.
The sensors in general are all pretty robust giving rare issues if any! Injectors can play up, but not often. Failure items seem to be confined to the Engine "Pump" and the fuel tank lift pumps.
I say Engine "Pumps" as they arent really a pump. They cannot draw fuel from the tank alone, they need to pressured supply because they are actually a Fuel Rail Pressureizer Pump to keep the Fuel rail that supplies the injectors at a very high pressure. Engine pumps are NOT timed by the way. Theres no need for them to be.
A failed Fuel Pressureiser Pump will not show or illuminate the engine diagnostic light. The car simply wont start.
Unfortunally, the items that can fail are the expensive stuff.. Engine Pumps around £100 second hand, injectors around 40 each second hand too... VERY expensive re furbished... Fuel Tank Pumps around 80 quid.
So theres a rough general assesment of what can go wrong...
So generally the actual electronics are very strong and robust! Hence the good milage the 8v 110 engines achive.

Re: 2.1td vs 2.0hdi pros & cons
As above I think that was my thoughts when the HDi first appeared as well, there's nothing wrong with them but the reliability is reduced to not far from that of a petrol unit, simply as the HDi depends on electronics and a selection of sensors to run, compared to a IDI unit. That's not to say petrol engines are unreliable, far from it, just the HDi *needs* the sensors to run.
But yes, they are generally very reliable and strong. I do recall issues with early models with certain pump types though, they would lose metal debris into the fuel system (I think the pump started to break internally) which at the dealer would necessitate a complete new fuel system (pipes, the whole lot) most were done under warranty and it did not effect many, I think one "batch" of one make of HP pump.
I'd buy one though, there's enough bits around used if needed and I've seen plenty of very high mile cars that have never had any serious problems.

Re: 2.1td vs 2.0hdi pros & cons
There is a C5 on ebay with 286k on at the moment. Spares seem to be readily available and cheap at the moment, especially for the C5, this is probably because once they reach about 10 years old they are not worth anything - long may it last
