Instrument failure ??

[Tubthumper]

Thanks Matt, I had considered that, and have checked the plug to it, but thought that if the sensor failed, you got a noticeable drop in power, which it doesn't appear to get ? Mind you, mine's the 90hp model, so any slight hill shows up a noticeable drop

Hi there

I didnt get a loss of power with my car just the speedo stopping a warning beep and something flashing up on the mfd that was to quick to read .It initially only happened every couple of months and then started to happen more and more often. I ordered a new sensor from peugeot think it was about 45 quid but then checked on ebay as an afterthought and they were only about 20 quid i think. Simple enough to fit just had to spin the wheel slowly by hand to get the teeth to engage and then just one small machine screw to hold it in.

Hope this helps cheap enough to try first before taking it to a garage.

Thanks again Matt for the info. I'm not getting anything come up on the mfd , but for the sake of £20, I should really try changing the sensor I suppose. When I checked the plug to it, My Haynes told me to get access from under the car, but even after taking off the under tray, it was still a real fiddle to actually get anything onto it. Did you get at it from the engine bay ?

I was lucky enough to be able to use a two post lift and get in from underneath im not sure what you would be able to see or reach from above. It is a little bit fiddly to get the screw out of the sensor but not too bad.

Good luck Matt

I've managed to get a day off work tomorrow, so I'm going to re-solder my clocks , just to tick that off as a possible cause, if nothing else

[Tubthumper]

Right, Having taken the clocks out, taken the casing off to get at the circuit board, resoldered the main post joints, put it all back together again.............. absolutely no change The next thing has got to be the speed sensor. My local Pug dealer has one on the shelf @ £52 , which sounds expensive compared to some I've found on the internet, Is it a false economy going for a cheapo one of these over manufacturers part, or are they pretty much all the same ?

I had a feeling

That depends if they're making Mickey Mouse copies somewhere. The part you'd get from Pug will probably be made by Valeo, so if you can get the same part elsewhere without the dealer's huge mark up then go for it.

I had the same feeling, but being ever the optomist, I'd hoped for an easy/cheap fix. To be honest, I'm flat out at home and work at the moment, so I have booked it into my favourite garage, at the beginning of Nov, for them to sort both sensors.

[Tubthumper]

Right, after the dismantleing of the clocks etc, I noticed that the fuel gauge needle read incorrectly, and on checking it, it looks like the needle stop had moved. I filled the tank right up, so that I knew where the needle should be when the ignition is on, checked by turning ignition on, so the needle rose to indicate a full tank, and fall back when turned off, and refitted the clocks. Now, having done 100 odd miles, the needle doesn't appear to have moved from reading completely full. Any ideas ?

[Tubthumper]

Dropped the car off at the garage, so will let you know what they find when I get it back later

[Tubthumper]

Got the car back .............

The garage changed the speed sensor, drove it up the road, and on the way back, the needle dropped to zero They also tested the temp sensor, and the guage ,which are both working , so the faults are either a loose/faulty plug somewhere, a broken wire, the bsi, or more than likely due to it being French, all of the above

Why oh why didn't I work just that little bit harder and buy a V70

Both go to the BSI on the same connector, 26 way yellow, after that they're mux. Might be worth a prod...

Any idea whereabouts this connector is ?

[steve_earwig]

On the BSI. I'm clutching at straws here but as it all goes digital from the BSI to the clocks I reckon it's unlikely to be just these two things further on. Unless, as you said further up, the BSI's gone APESHIT.

[Tubthumper]

Am I right in thinking that the BSI is behind the fusebox, under the steering wheel , and does the fuse box have to come out to get at it ? Any pics would be really useful
