405 SRI Speedometer question

Mark_Casey · Post by **Mark_Casey** » 21 Dec 2004, 00:44

O.K. my first post here and perhaps a silly question...The speedo needle tends to constant bouncing while the Tacho needle remains steady.Variation is approx. 5km's either way...which is enough to collect a fine down here in rip-off land hehe.
Is this simply a characteristic, or do I have some guages dismantling ahead?
cheers, Mark.

Sorry mate thought your in Ozz not old blighty (rip off land). Not to sure about the 405 but the Citroen ZX has the same fault. Only cured by a complete replacement of the speedo cable, both halfs on a ZX.

Hi
Nothing wrong with your speedo mate, Its the cable you need to replace to cure it.
Its a very comman fault with the 405.
Im on new cable number 2 now.
Stick a whole new cable on & see.
Sometimes the speedo drive in the gearbox also needs replacing, Small brown plastic worm drive on the end of one of the driveshafts. But thats a driveshaft out job, Wait till you stick a clutch in it & do it then.
Theres also the drive gear on top of the box held in with a couple of 10m bolts that sometimes goes.
Try the cable first mate & report back.

Thanks for the info Stuart and PowerLee...gee, great little forum this one.
I'll be seeing about a speedo cable over the 'break'
cheers, Mark.

Hmmm...on taking a gander it doesn't look like a 'simple' job..I now have a new speedo cable $70.00 from the local Peugeot dealer (what was I saying about rip-off land).
Think I'll wait for the Haynes manual to arrive which I scored on the e-bay for 50p (what was Stuart saying about rip-off land hehe)

Hi
The 405 speedo cable is a fairly annoying job to do.
The first one you ever do is a right pain, But once you have mastered one they are fairly easy!
Wait untill the engine is cold so you dont burn yourself on the exhaust manifold.
Theres a bracket the clip that holds the cable locates on to on the bulkhead behind the manifold, You can just about get your hand to it.
Make sure you use this clip otherwise the speedo cable will touch the exhaust manifold & melt & you will end up doing the job again!
Theres a rubber grommit near the speedo end of the cable that locates & holds the cable in the bulkhead, Make sure you locate this correctly in the bulkhead hole.
Theres is no need to remove the steering wheel to get the instruments out, Just drop the steering wheel height adjustment to the lowest setting, Wiggle the instruments assy as you remove them & they just clear with about 1mm to spare, Even on the airbag equipped 405s.
The fun parts getting the cable attached to the speedo itself.
Ive done a series 2 405 cable a couple of times, Peugeot didnt fit a clip to hold the cable on the speedo, It just pushes on.
But the problem is you cant get your hands up behind the speedo to do this with the electrical plugs connected.
Theres 6 electrical plugs on the back of the instrument panel assy, Theres a white plastic clip that hold them in place, There different sizes & colour coded so you cant mix them up.
The trick is to use some string tied on the white plastic end of the speedo cable to guide it on to the back of the speedo, Feed the string out under the instrument panel assy & pull gently, you will feel it when it connects.
Once you master this trick, Its a 10 minute job to put it all back together, It took me 4 hours the first time to get the cable attached.
You never said what year the car was, A series 1 405 might be different, Ive never done one of those.
Or offer a Pug mechanic some beer tokens to do it for you.

Cheers, PowerLee. It is a 93/94 model http://www.andyspares.com/discussionfor ... IC_ID=8459
My previous car was a 504 and my helpful mechanic (a Peugeot specialist) advised me to stay away from early model 405's.
Thanks for the tips too...I'll definitely be giving it a try

Hi
The first one is a pain to do, But once you get the hang of them they are easy.
Make sure the curves in the cable are not too tight where it bends behind the manifold & again where it bends in to the bulkhead, Nice large curves.
Theres 3 torx 20 screws, One at the top that you can see & 2 are hidden behind a piece of trim.
Lower the steering wheel down, That strip of black plastic trim at the bottom & in front of the instrument panel assy will unclip if you get a finger under it where the steering coloum goes through in the middle & lift it upwards.
Remove the 3 torx screws & the instrument panel assy is free, Unclip & unplug the elctrical plugs & lift the whole assy out, The cable will just hang there out of a black plastic tube.
Now is also a good time to replace any blown bulbs!
If its an airbag equipped PETROL model, The low coolent level warning light SHOULDNT have a bulb fitted to it, Peugeot nicked that bit of the wiring for something to do with the cat, Its the moddified 405/406 loom to thank for this.
The DIESELS DO have a low coolent warning bulb fitted.
I know an SRI is the XU10J2 petrol but you never mentioned if it has the drivers airbag fitted, August 94 onwards for those.
I also noticed a rear boot spolier isnt standard fittment on the SRI Down Under, Is that something to do with this luxary car tax Ive heard mentioned before?
Also no Red bumper stripe & no alloy wheels either [:(]
All UK spec SRIs since the launch in 1988 have had a rear spolier fitted, Red bumper & side trim stripes & alloys from around 1990.
Also you can if you wish fit a bulb to the dim headlamp warning light, next to the dipped headlamp warning light if its missing, Peugeot stopped fitting these to save a few pence.

You aint kiddin' eh? Despite having no manual I decided to have a preliminary go at it...
This is a late '93 model so no air-bag...however,after removing the 3 torx screws there aint no way the gauges
can come out without the removal of the steering column shroud.
Still unsure where the other end of the cable disappears to, so decided to put the thing back together and wait for the arrival of the manual...getting the tip with the string was definitely handy, but no less of a challenge.
I could get no sense of when it engaged in the correct position and only method of testing of course was to drive the car down the street...which took several attempts before it finally worked. Hoping for a better result the next attempt.
cheers, Mark.
P.S. I don't know about 'luxury car tax' but even the 504's down under were short of a few 'luxuries' that French versions seemed to get standard.

Hi
While the steering coloum shroud was off, Did you spot a grey plastic box with a electrical plug connected to it hidden inside?
The speedo cable comes out of the bulk head behind the exhaust manifold.
It goes along the bulkhead & then connects to the road speed sensor thats attached to the top of the gear box.
Look on top of the gearbox & you should see a white connector plug attached, Its in the area under the air inlet trunking & battery tray, Its fairly well hidden.
Find that white plug & thats the road speed sensor, The speedo cable attaches to that.
You must keep the new speedo cables curves nice & large where it goes behind the exhaust manifold & then again into the bulkhead or the new cable will start jumping too.
Make sure the cables rubber grommit locates correctly in the bulkhead.
Also make sure you clip it to the bracket on the bulkhead behind the exhaust manifold or the cable could touch the manifold & melt!
