2.0 Hdi (diesel) cuts out at random.

[steve_earwig]

Seeing as how the D8's an import from France and the D9's an import from Italy I'm guessing they're just for the Brits.

[Welly]

Yes, see us Brits do not want spots of oil on our block paving what what.

You ought to see my under tray - it's clinging-on for dear life

Tie-wrap anyone?

Nether of mine have undertrays and, according to Service Box, that's how they left the factory.

Ditto

Thanks Springnuts, no I don't have the plastic undertrays fitted! The car came without them and I did try to
obtain them from our local dealer. The very friendly & helpful parts man (Ray from Browns of Louth) priced a new one up at £135
but I declined. He then said he would have a look around because he might be able to assemble all the parts from his collection of bits in the store. Ray was also at that time running a parts shop on e-bay (you may have seen it).
The deal was that he would contact me when he'd got it all ready, then guess what happened? The receivers were called in and the dealership went down the Pughole! The staff were given no notice at all on the Monday it happened and are now jobless.
I now have to travel 18-20 miles to Grimsby to the nearest dealer. Quite a lot of people in the town who run all sorts of Peugeot's now very unhappy and threatening to do something silly like buying a Hyundai! (comes with 5 year warranty though-but hwere's the fun?)
Got to go now, m tea's ready!

...down the Pughole!

That's funny, even if it was a typo...

I wonder if my D8's lack of undertray is anything to with the reason it has hot climate cooling fans? Don't know about the '9 tho.

Hmm...

Here's a thought: How far is the undertray away from the sump?

[mjb]

The undertray goes around the sump but doesn't actually cover it - at least on the tubby+V6

ISTR there's 2 versions of the undertray on servicebox?

[steve_earwig]

I've just had a look and I'm very confused There's sound proofing with or without an engine shield, looks like there's early and late, saloon is the same as estate but coupes are different and there's one of those LE things that I don't think I'd get even if it was in English.

And just what the fook is "grand export" about, "GUARD SHEET MET " - is that guard sheet METAL??!! is that really a bash plate?? Gubber me, I want one!!!

Hi all,
My first post so please don't give me any greaf for owning an 806
I have been haveing the same problem but untill now have'nt been able to find any anssers.
Some history, 2000 806 HDI 110, 130k but has been a taxi and a hier car so I gess it's been clocked
It runs on BIO-DIESEL (made in my shed), with no problems untill it started cutting out.
It cuts out on pump diesel as well so it's not my fuel.
So far it's done this about 30 times,will allways restart after a few minits and and there is patern to it, sometimes it goes for 500 miles, sometimes just 2 or 3 but it does seem to be bettor if it has over 1/2 a tank.
I changed the fuel filter and droped the tank to clean it out just in case it was full of gunk but none found.
So it sounds like it could be either
trottle position sensor
pump relay
crank sensor
or cam sensor
So I'll start with the pump relay, does anyone know where it is on the 806 ?
You can't get a Haynes manual of one of these buses so I'm afaid I may be asking a lot of questons.

Thanks in advance.

Ps. my spelling is not so good but feel free to pick me up on it

Hi all,

Well ours has two undertrays. Together they cover the whole of the underneath of the engine. The sump plug is on the line where they join and overlap by about half an inch. So, you have to remove both trays every time you do the oil. The back one is smaller than the front one, and is easy to remove - it has four round headed ridged and ovaloid pegs which push into a clip which is itself clipped into the underneath of the car. (Original fittings were stupid small (M8?) nuts and bolts; the nuts held into the car by integral clips). To remove the pegs , just rotate 90 degrees and they drop out. The front one has four M10 bolts which go into 4 captive nuts - held into the car by integral clips. Once the bolts rust to the nuts trying to unscrew them destroys the clip so that the bolt and nut just rotate round and round and you can't remove the tray - well you can - you just have to grind the head off the bolt. When I got the car the trays were torn and tatty, and held on by a couple of rusted nuts and bolts and some cable ties. I didn't like the idea of £135 for a set of trays - or was it £135 for each tray? - so I repaired them with old baked bean tins riveted in place. Biggest confusion was over the pegs and clips for the back tray, because they were different to the originals, but I have to say the system has worked perfectly. I guess the front tray is too heavy to use the same system.

Regards

Oo er! seemed to have started some members worrying now about undertrays. Sorry! With reference to Springnuts comments about the undertrays being different, my local parts man Ray (see last post) did say that a number of 406's had different shaped undertays and that they aren't tranferrable, which means that Peugeot can and do charge a hefty price for some bits of plastic.
I did think the other day that maybe i could make one up out of marine ply if it was thin enough, but then I reconsidered it because I could'nt be bothered-I'll keep looking for the genuine plastic article. Having read the comment from Mark806 with an 806 about it cutting out, please have a look at BBA-REMAN forum and the comments about HDi's not liking bio-diesel or city diesel. Apparently according to the info here, bio-diesel/city diesel does unpleasant things to the fuel system and they only like real diesel (whatever that is!)Sorry couldn't provide a link, started to write this and just recalled the info from memory. Note for Steve-my comment about the Pughole wasn't a typo-it was my sad attempt at some humour. As you all will know, owning a Peugeot of any description ought to carry a warning-ownership will result in a sense of humour bypass and an empty wallet!
(We love 'em really-don't we?)

I wasn't sure, funny tho.

I'd like to know why both of mine came without undertrays, according to that article I gave a link for they actually help with cooling (intercooler as well as radiator) so I don't see the reason (apart from the usual cost-cutting).

I still like the idea of that undershield, having had quite a few chances to look underneath recently ( ) I notice how bashed up that part of the car is. Alright, it gained a good few centimeters at the front when I had the front springs changed, but the marks are all the way under the car - a result of the wonderful roads here. If it is sheet steel, if I can work out those RP things, if I rob a bank... Besides, it's cheaper than the undertrays.

I didn't see Mark806's post before (sorry) but I read running an HDi on neat biodiesel is a no-no, from the description I think the tank-mounted lift pump is crapping out.

[Wrinkly57]

Steve,according to Service Box, mine didn't come with the trays either but strangely enough the fixings are there!
Never mind, it's still running, who cares if all the underneath gets mud on it? (Round here with all the cows and horses there's often something else up there as well!)

Thanks for your coments guys.

As for running on bio-diesel as long as it's well made there is an improvment in the way an hdi performs, many people have had problems with badly made bio messing with some of the sensors.
The lift pumps give up if make them pump veg oil (veg and bio are compleatly different BTW).
If any of you are interested have a look on www.vegetableoildiesel.co.uk
I think I managed to track down the fuel pump relay today, if I have the right one it's a brown BITRON 15 pin with the numbers 240109 and has the date 20/06/00 on it so is the original unit,
I'm of to the scrappy tomorrow to get another one.
Ps. it's now had around 500lts of pump diesel run through it and stull cuts out.

[mark21TD]

Hi all.
I couldn't find the right relay in the scrappy but did manage to pick up a MAF sensor which has made a big difference to low down power, when fitting the MAF I found a fuel leak on the injector leak-off pipes and replaced with new pipe, hopefully this will stop my clutch (was replaced 2 years ago with the DMFW only £716 ) from slipping as fuel was tracking down into the bell housing.
I also took the crank sensor out and cleaned it but don't hold out much hope that this will stop the cutting out.
So it's off the the main stealer in the new year for the pump relay.

Hi Mark806,

Well it is probably the cheapest bit you can get from a main dealer!

Actually on reflection it isn't. New thread coming ...
