Speed Sensor or Techometer issue

[rightinfront]

When bought the vehicle the speedo was bouncing around and a buzzing noise was heard when it worked now and again. I had a machanic replace the speedo sensor with another from europarts and since then the speedo has not moved. I left it till the MOT and judged the speed via the rev counter. Last week I borrowed a friends clocks to test to see if the problem was there, no change.

I bit the bullet and paid a dealer to diagnose the problem, £57 down and 10 minutes later, they hit me with a bill for £681 to strip and replace the techometer screw and the control pinion it is connected to the speed sensor, parts is only £23 the rest is labour at £97 per hour.

Tomorrow I will get someone to replace the control pinion and to actually test to see if the clock needle moves when the pinion is turned. I then will know that the issue is the techometer, which in my opinion should have been done by the dealer in the first place.

If it is a techometer (worm) I think my cheapest option would have to buy a second hand gearbox and have a clutch replacement, might as well with the gearbox out, by local garage like that works out at only £255. I am still miffed that the dealer never diagnosed the issue and what is worse they never gave me read out either.

Has anyone else had similar issues? and what did they do to resolve it?

Yes my speedo didn't work when I first got the car, bought a new speed sensor off ebay which made no difference, stripped all the wiring loom out of the engine bay and checked it all with a multimeter.

While I had the wiring off I spun the speed sensor in my drill which made the speedo rise so it had to be the drive cog in the speedo housing - its a cheap plastic cog.

Sure enough the drive cog that fits round the long driveshaft in the speedo housing was smashed, usual cause is ramming the driveshaft in too hard or offset, of course it could of just wore out too I suppose.

Easy enough to change but make sure you drain the gearbox oil before you pull out the speed sensor as it floods out.

Yep! I brought a techometer screw myself after rip off Peugeot quoted me £681 to do the job, took it to Mr Clutch, frickin great service must admit. Told them, I was told by peugeot that the gear box has to be dropped to replace the techometer screw and they laughed. Eh! no can be done easily, you have the part so just labour. Ask them to find a leak that peugeot could not find, 2 minutes later it is your diff seals.

Told them to do the job as well, walked round to dealer brought seals 30 minutes. Back at Mr Clutch 20 minutes later they have fitted the Diff seals, techometer, tightened bolts in my gearbox that was loose, replaced the bottom bolt on starter motor, and replaced a CV clip. I had missed my re-test for the MOT at peugeot, I told Mr Clutch to do that as well, total time 1.8 hours. Cost £161 including the MOT, Bloody bargain!

Diff seals? Do you mean the driveshaft seals?

Yep! Driveshaft seals.

Now speedo is fixed I am getting the buzzing sound over 6 miles an hour. I do not get a bong when I unclip the roof so I think that is the micro switches in the roof (A-B), once I do that I will manually reset the the roof. I suspect that the retactable roof closed switch (K) is inop also, but it is all one step at a time. All this info I found on this site.

At last! Someone else with a good word to say about Mr Clutch. Hooray!

That was the 1st time I went to Mr Clutch, second time not so great. That said the car is booked for another job in another branch of Mr clutch, just can not beat the labour charge elsewhere.

Do you get any door or boot open diagrams on the multifunction display or when driving does the interior light flash in the door position?

God no, I will not go to a garage for the buzzing as it all above the ground, to old to scamble under a vehicle.

Buzzing so far:
Micro switches checked, still no bong when I open roof catches, also the boot does not click in when boot is down, can not reset either, reading the treads suggests that the ECU does not know where the roof is.

What is strange is that if I down the windows, open the boot lid (have the wife hold it), the roof retracts and the boot locks into place, drive around, it's not buzzing roof down.

Roof up using botton, all goes well till the last cycle the boot will not go down, I have to turn the hydrolic to get the boot down and again, does not lock, little white catches I think should lock the boot.

Because of this, I still have buzzing sound while driving and I suspect it is because the auto lock is not happening.

Well bugger me and call me Jane, I re-read the posts on the site last night and thought that this has to be a mircroswitch, and it has got to be the last mircroswitch in the system, sort off answered my own question.
Anyway took a good look a K retractable closed roof switch and noticed (how I missed it) that the fiddly little silver was missing but the switch seemed to work. Call to Peugeot "how much s the part" "97 quid sir" well you can image I almost choked on my tea. "OK, but you and I know that the silver bar on them things break, bend, pop off or gets lost, can I not buy that instead" "no sir".

So, call to breakers they have a few in Pugs in stock, drive up there and climb to the top of another car pop the boot climb in, bugger I can not get the whole switch out. To dangerous to tip the roof as up in the air. So I took the silver bar and the screw just in case total cost 50p plus fuel.

So the back home, lucky I have the screw as I had to use a hammer and screwdriver to turn the screw holding the microswitch, as someone had chewed up the screw. refitted the bar, opened the top part of the boot, used an bar to hold it in place, turned the screw on the pump so I can the move the roof half way without it falling in the boot. Bit of a balancing act here.

Now you can get the microswitch in place witout twisting the bar or popping it, note this position will allow to remove and replace the whole switch. Replace roof, close the lid, white hooky things back to auto. Open the boot and recheck that the mircoswitch is positioned correctly, I resprayed the area with WD40, tighten the pump screw, pull the cover over, and close the boot.

I then turned on the engine, the roof is already unclipped so I pushed the roof switch down, waited whirring noise to cycle and the click as lock in place. Jumped out the car and checked the boot, I did a jig and a whoop. Tried the other way roof down, unclipped the roof bong sound, roof up now the buzzing test, took baby out for a spin no buzzing noise. with roof up or down.

Result! Well done - and thanks for posting how you did it -an interesting tale.
