Pug/Cit 1.9TD engine starting problems in Synergie MPV

the rev counter is usually driven by the unregulated output on the alternator. No doubt this engine has an ECU which might also make use of this to determine some things about the engine's operational status..

You are allowing time for the heaterplugs, right? On nearly every pug

Do you notice any noises or smoke from the engine during starting attempts, or shortly after the engine does start?

We've had this car 2 yrs and its never been a problem. It does normally start okay without glowplugs if its at normal running temperature.

Shouldnt require any pre heating at any point after the engine is luke warm for an immediate restart. (if it does, its worn or has some other problem- eg poor injector spray pattern)

Tim..

it did a

Driving it like that won't do it any harm. My s**te old 405 1.6i petrol did

Tmax, Don't bother contributing if you can't put something sensible.

So what if its done a long drive.....its a diesel....it was at constant motorway speed and like I also said it had just been serviced. The point I was making is that once the car has fired up, it runs perfect.

Its not a bit shagged, it was doing it in the Vendee before the trip back. All thats up with it in my opinion is that some kind of fuel switch isn't functioning correctly and I was hoping some PSA XUD engine veterans could guide me a little further.

"Then owner scratches head and wonders why it's a bit shagged.".....gobshite, my last diesel did 256000 miles before I sold it and it was still mint., next......

and

Should have kept that one, then - this one sounds as if it can't withstand the mistreatment, next.....

Well..... I have a life....., I don't have the option to just stop what I'm doing and put the car on ramps whenever it suits me. I occasionally post queries and the odd response to this very usefull newsgroup before I jump in feet first and doing unnecessary work. If you don't rate the value of this NG, then don't bother accessing it. I'm sure you won't be missed.

You still consider driving at a constant 80 ( French motorway speed ) thrashing the arse off a car!!!! You need your bubble bursting. Just to come out with s*it like that is demonstrating to this NG that you don't even rank as an amateur. I've been driving between Manchester to Leeds each working day for the last 12 yrs at at average speed of 75-80mph. Most of my cars leave my hands in a better condition than I'd bought them

Yep...it happens to the best ov em occasionally. Even new ones. Mine do 20K per annum so I expect the odd glitch.

So I ..like got rid of my 10 yr old Audi 80 for a seven seater cos I like the look of MPVs. Some of us change cars for reasons other than the last car becoming unreliable.

I think you're better off contributing to alt.time.wasters as you've just cost me ~10 mins responding when I've got more important things to do.

Well, the PSA XUD is a well proven lump that isn't really known for having a short life.

No the price is a more expensive turbo & fuel injection system

Not really, they're designed & built to easily cope with that, full load hot running wears very little.

What utter utter rubbish.

Running any well serviced and otherwise fit engine at upto ~80% of full power/ revs constantly will not do it any harm whatsoever, in fact it would do it good, if it had recently spent an amount of time at low load / revs.

Do we hear of german autobahn driven cars blowing up- and some of them are run at 100% for hours on end- thats peak revs and full power- no.

Damage only occurs under circumstances such as excess revs / load with a cold engine, or constantly banging it off the rev limiter in a low gear where torsional vibration takes it toll, or where particually oil quality is low and or the cooling system is not up to scratch and excess temperature results.

Please don't post here again unless you can say something constructive.

Tim..

In most applications of the XUD you'll find it is turning at about 2500rpm at 70mph anyhow, and infact unless you drop to 4th gear it wouldnt hit the governor, which infact the sole purpose of which is to set a safe maximum rev limit the engines internals are happy at, and will turn at pretty well indefinately given reasonable load.

If you've ever driven a Transit van, you'll find they will survive upwards of 250k miles constantly sat at the governor rpm limit quite happily without going pop. The XUD is likewise pretty bombproof.

Tim..

Here here Tim..... Tmax is a bigoted obnoxious tosser who only suceeded in jumping in feet first and steering my original post off onto a tangent. Your words emulated my thoughts but I think they are wasted on him, so I never bothered.

Can I steer this post back on course and ask for advice about how the ignition key controls the fuelling. One thought which had cropped up is maybe the immobiliser is playing tricks. Last night, I drove the car home then got back into it minutes later and it wouldn't start. First try was a long burst on the starter motor for say...15 seconds. Then I tried again for 10 secs....Then 3rd time it fired up perfectly with no smoke or lumpiness to suggest excess fuel. I know I said the rev counter has gone on the blink at the same time, but I can't personally believe there's a relationship. However, stranger things have happened and this info might mean something to somebody out there with a Xantia or 406 etc. I'm off to write another unrelated r.c.m. post now but I'll check this one later. Thx

Please don't tell me what to do, Tim.

There's a good lad.

No he's requesting you not to post here again unless you've got a clue, not telling you.

Ah, it sounded like a command to me - but I'm prepared to accept that it was a request.

However, after due consideration, request denied.

You're just looking for attention.
