Not really anything exciting and probably pretty rare but could be useful info to someone in the future.

This is based on a non-multiplexed car, i don't know if it's the same for multiplexed.

The problem:
I was driving my 206 about and I noticed that it felt like the car was travelling faster than the speedometer was reading. Checked this by following a friend at exactly 30 on his speedo and by using a sat nav and my speedometer was under-reading by approx 5mph (friends speedo showing 30, sat nav showing 29 and my speedo showing 25). Standard size wheels and tyres are fitted to the car.

The cause:

It turned out to be the instrument cluster. If you look at the speedo with the ignition off the needle should be pointing at the line representing 0. Mine was lower down.

When you turn off the ignition the rev counter and speedo needles should both dip past their rests and then come back up to 0 (resetting).
In my case the speedo didn't bounce back up, resulting in a bad reading.

I chose to replace the speedo rather than faff around with the old one. (30 on my speedo is now 28 on a sat nav)

Basic description for removing the speedo
To remove the speedo you pull off the cover (held on by metal clips, watch you don't snap the plastic), undo the 1 torx screw on top of the speedo and pull it towards you. remove the two plugs from the back and it's out. To refit it do the same in reverse. The mileage will be inaccurate if you don't get it corrected so it's a good idea to note the exact mileage before you disconnect the old speedo and note the mileage on the new speedo so you can work out the cars mileage in the future.

Very minor thing but felt it worth noting.

Cheers

How much did you pay for a new speedo unit, I've broke the milometer screen so need to investigate a new one.

Slightly wrong. Wink Buy a speedo with a lower milage. Your BSI will change the ner lower milage to your old current one. However buy a higher milage one and then it wipes your data and thinks that it has done the higher milage. Wink

Wrong Wink
Buy whatever speedo you want Wink

The above is only true on multiplexed cars.
It's well known that pre-plex doesn't need this doing, indeed I changed mine and this didn't happen.

So what happens on pre plex then? The mileage stays the same even if you put an older ( higher mileage ) unit?

The mileage will be whatever is on the actual instrument cluster you plug in to the car.
