The display is going out in my 2006 S500. I see rebuilt units on ebay, but they aren't much less than a new unit at a discount price. Is it a fairly good gamble to buy used, or should I go for the new unit? Is it plug and play?
Thanks for the idea, wallyp. The display is turning milky and is becoming dimmer. I believe the connectors are firmly inserted as it functions properly
Not familiar with "turning milky", but getting dimmer could be a poor connection slowly reducing the voltage to the display. I would still check and clean the connections. It's free and easy...
I suspect like almost every other Module, this will need coding via SDS to the specifics of your car :wink
A s/h unit from an absolutely identical vehicle, with exactly the same options as yours may well plug and play, but personally I'd check and code if necessary :wink
If you are good with your hands do like I did: got a second hand control, took it apart and only changed the LCD display itself; not a particulary difficult job, and no coding required. The LCD display has a flat ribbon connection.
1) Do as Kraut56 says, as long as there isn't another problem in the CC Panel, that will work
2) Get a good Indie to code it for you
3) If you are serious about doing all the work on your car yourself, Buy SDS and teach yourself how to use it. To work on these Cars it really is a 'must have' piece of equipment :wink
for the LCD display there are no light bulbs involved, and no soldering is required.
The LCD display is snapped and held into place with some plastic retainers.
You have to look carefully how the ribbon is connected and held in place to make a proper contact connection. I think (remember) this is just a ribbon-pinch connection, not a pinned connector.
BTW: I actually used the LCD display from a front dashboard unit to repair my rear passenger HAVC unit
Just as a note I don't believe there is any coding required for the control unit. Has when it is removed/installed WIS only states to connect STAR and read out fault memory. So if you can get a secondhand one just install it and all should be good.
That will be one of the very few Modules on these Cars that doesn't then :grin
I'll take a look when SDS is plugged in next day or 2 :wink
Cheers Dave
