406 multi function lights/tappets

Many thanks nigel "Michael Roche" and "Malc" for help back in
February....not forgetting Peugeot UK HO for on line help (no, they have
not moved to east Budapest..yet!!). The multi-function display unit
required 2 bulbs (not leds), which makes the model a mark I, or as Peugeot
describe it a "pre-facelift 1997 built 2.1 Turbo diesel 406"; for the
edification of anyone with an early 1998 purchased 406 Estate, the VIN
number reveals all, should parts be required.
After fitting the bulbs, the unit revealed the outside temperature of 12
degrees C. straightaway. ..and that was it!. No 'Range', 'Current Fuel'
consumption, 'Average consumption' 'Average Speed', Distance
travelled'...(or the outcome of the Iraqi War); see pages 46-47 of owner's
handbook. Dutifully pressed windscreen stalk for 3 seconds minimum on
steering column...no joy. (the battery had been disconnected
recently.)What is knackered?..the basic unit?, the..fuses? screen wiper
stalk? or me?. Now to become highly technical..when I pressed my fingers,
gently, on the multi-function screen, it was possible to see life beyond
Mars..there, faintly illuminated in the background were the results I
would have liked to have achieved...rather like the story of my life. Can
anyone help further please before I am compelled to raise the extra
mortgage required to visit the average Peugeot main dealer.OK it's no big
deal on a 130.000 model which still sings along without problems, but it
would be good to have everything working.
