Peugeot 406 speedo - Stumpy
Can't find this covered already, so please help. I see from reports that speedo failure on 406 is known problem. What is the usual fault ? ( yes I know the needle stops moving ! )Is it usually the dash unit or something in the gearbox. I've checked for loose connections to the dash, so I assume its a replacement job. Any good contacts for the parts needed would be appreciated.

Do you have sat nav fitted?
Looks like if you do,as per car by car breakdown,it could be linked.
Don't have a cure though, sorry.

Has yours failed Stumpy? If so, what model is yours. On the 2.1td, the usual cause is an "interface" box, found high up in the glove box compartment, with a lot of other "boxes". This is a box of electrical gubins. Mine failed at 45,000 miles. I first replaced the electronic drive unit(£40.00), and when this didn't work was then looking at the speedo head (about £200.00), when by chance the person at the local Peugeot spares told me that he supplies about one "interface" a week for the 2.1td. This cured mine.The failure may be caused by another component on other model types i.e. 1.9, 2.0 etc.
