A few minor issues

[pandp]

Just recently been given a 406 1.9 TD LX from my dad. My dad had a few starting problems and thanks to you guys is in the process of elimination on my welcome page.

There are a couple of other minor faults that i would like to put right if anyone could shed some light.

The LCD milage display does not work and the right side of the instrument cluster is unlit. Clearly a bulb needs replacing to light the right side but am i right in thinking the LCD is seperate and replacing the bulb in the cluster will not light the LCD?

Another fault i found was trying to open the fuel flap. The lever down the side of the drivers seat, you can pull it and see the flap move out but when you let go it locks again. I have to wedge something under it so i can get to the partialy open flap and pull it open. Anyone else had this problem?

Only had the car since Sunday and so far this is all i have found. Apart from these it's a great car.

Firstly congrats on acquiring (IMO) the best engined 406, bring on the veg oil!!

To answer your question the mileage display is indeed seperate, best thing to do is pull the clocks out and have a look for dodgy connections.

There is a excellent how to on D8 clock removal and repair, it doesn't cover the mileage display but you'll get the idea.

You'll need the display working for the mot as it's a legal requirement but I don't think the mileage is recorded on the display on a D8 so you should be able to swap either the clocks or the display from a scrapper.
If you can find a set with an oil level/temp gauge that 'should' work without any fiddling with electrics.
The display itself looks like it just plugs in and should be relatively easy to swap, just take your time.

A little tip on the bulbs, most factors sell them for about £1 each but if you ask for bulk discount they usually do them cheaper. I paid about £5 for 10. I use the heater plug light socket as a tester and plug each bulb in turn into that one to check they're working.

I've just read your original post about starting issues and I've experienced the exact same thing on both my 1.9td's.
A pin hole in the priming bulb or leak off pipes can be enough to let the fuel drain back whilst standing but usually takes a good 12 hours to drain back enough to cause starting issues.
Funnily enough only last week I had to clear a load of air from the pipes after a fuel filter change and amazingly enough it was mr Haynes that helped cure it.
Follow the fuel pipe from the filter to the pump and you'll see a union joint to the left of the pump, crack the top bolt about 1/2 a turn or so with a 17mm spanner, you'll propably have to move the pipes and ecu box lid for better access.
If the complete joint turns you'll need another spanner on the union body to hold it in place. Pump the primer and see if you get air bubbles in the fuel, I had loads in mine. I kept pumping while tightening the bolt to make sure none went back in. It's a bit messy so try and pack some rag or kitchen towel around the base before you pump the primer.
Unfortunately it's one of those jobs you never know if you've fixed until the next morning when it's cold and wet and you're already late for work

If that doesn't work I'd do the leak off pipes as they're cheap and easy to do with a sharp blade to cut the old ones off and some long needle nosed pliers to guide the new pipes in the tight areas your fingers won't reach.

Enjoy

Just to confirm, whilst the odometer/trip meter LCD is separate, the backlight bulb is part of the instrument cluster as with any other. They are 'T5' twistlock style bulbs, here's a pic of the rear of the panel:


The bulb you're after is the one directly below the blue connector in that picture.

As for the fuel flap, all the diesels seem to suffer with this. This thread lists some possible solutions (clothes peg spring is the usual one):

Mine ended up breaking 2 out of 3 hinges so I bought a new unpainted one from eBay for about £10, got the paints etc and did it myself:

Thanks very much guys for the welcome and all that info That's my weekend sorted.

With regards to the fuel, until it does it for me i'm not touching it. Firm believer in if it's not broken, don't try to fix it. If it does happen then i now know where to look etc, thank you.

The LCD display is still showing but is very dim. I'll pop the display out this weekend and see if anything looks obvious also replace the bulb whilst i am there. Now i know what bulbs they are i will pop to my local just near my work, thank you.

Nice job with the petrol cap So i take it it is the flap at fault and not the lever? My lever lifts and pops the flap out but letting go of the lever pulls it back in.

Gotta ask as this is my first diesel.....what is this veg oil??

Just to be sure as i have been on ebay and spotted few with the oil level gauge....This would just slot in but the oil gauge would not work? or is there a connection for it?

I have seen a lot of the LCD's displayed between the clocks but mine is within the MPH clock and it doesn't look like there are many of them around.

Just trying to find out if i can't fix the LCD on mine can any other sets be used?

[jonsowman]

If you can still see the LCD then it will be the backlight that has failed, just replace it with another T5 bulb and you should be good to go.

Be careful if you do ever have to buy a new instrument panel, there are about a hundred different varieties. Ask on here first and someone will be able to confirm whether it will fit!

With the fuel flap, if you open it up and look at the hinge you'll see that there are three plastic pieces holding it to the hingepin. I imagine at least the middle one of yours will be broken, which is what will be causing the failure to open. People have slotted a clothes peg spring onto the hinge pin, which works very well. See the thread I linked to above for more information on this.

The 1.9 XUD engines have the Bosch mechanical fuel pump, which will quite literally run on vegetable oil, which can often be bought in bulk for around £1/ltr. Some people choose to run a 50/50 mix of veg/diesel - use the search bar to look for more information on this if you're considering giving it a go.

Thanks again...i went to my local car shop and asked for the T5 but he said there are tons of variations so i need to take mine in or get a part number. The LCD is viewable if i catch the sun on it or if i shine a torch at it so all good if the T5 bulb will sort it. I certainly will ask on here if i ever need to change as i came across more than enough of them in my search.

I'll give the flap a go. I did read that thread and already claimed a peg to do the job.

I have never heard of the veg oil before but then again i have never owned a diesel. Definately going to have a read up

[jonsowman]

My apologies, you need to ask for a 509T, they look like this:
http://www.ebay.co.uk/itm/10-X-509T-TAC ... 0984173844

The Peugeot part number is 611234, but saying "509T" should really be fine.

Very big THANK YOU for all the help and info guys

I now have a well lit dash and a trip meter i can read. I had one bulb left so set about looking for somewhere to put it. I found a display above the stereo that has always been blank, i assumed it worked in conjunction with the original stereo which i do not have. Anyway i replaced the bulb and found that it displays the temperature shame it's in C and not F.

I also dismantled a clothes peg and now have a fully functional flap lol.

As for the non start issue, it has not done it but i will be keeping the info should it happen.

Very happy and the car is looking better by the day due to getting a very much needed clean.

[jonsowman]

Glad things are getting sorted, it'll be back to factory condition in no time

I believe you can switch the display from C to F by grounding lead 8 on the upper 15-pin connector on the reverse of the unit.

I didn't think the LX spec cars ever had the temp display unit fitted, I was clearly wrong!

[gumby6371]

glad your sorted, temp sensor on an lx is news to me as well. Maybe a previous owner retro fitted it either way it's a bonus

[pandp]

Cheers, i'll try doing that. I'm just finding things as i go around lol.

One thing i can't find is the front fog switch unless the stalk switches front and back at the same time but it does only have one position.

I have no idea what is supposed to be in this car and what isn't. Now it's clean i'll get a pic up and see if it is standard or not. Stereo definately isn't standard.

[gumby6371]

Front fogs aren't standard for the LX, but then again I didn't think the temp sensor was either.

If they're retro fitted you have to change the stalk, it you've got them maybe whoever fitted them didn't realise they needed a new stalk or possibly rewired the stalk to do front and rear. Try it and see is the easy answer.

New MOT regs are strict on warning lights so I think you need the dash light to come on when they do but I could be wrong.

[pandp]

I'm starting to think this car has had a few extras added.

I did try the fog lights but no joy. My dad said he never got them to work, that's the reason i started looking for the switch.

Here are a few pics to see if anyone can work out if it's standard or not.
