intermittent display disappearing and cooling fans running on
Hi everyone, I have just bought my dad a 2002 e240 but has a fault that the seller did not inform me of. When the car gets warm the multi function display goes out, dash lights flicker on and off with speedo going up and down then all goes out and nothing displayed.
Has anyone any ideas on what is causing this fault. thanks

Edit: not to insult you; CAN is controller area network, that links groups of systems together and shares sensor data and inputs between them. More information about it is here https://mbworld.org/forums/e-class-w...a-network.html if anyone wants more.

Hi NAFT1 thanks for your reply.
When you air con, do you mean in cold condition ? I picked the car up from my dads tonight to try and diagnose the fault over the next couple of days starting with alternator and battery and going from there.
On the way home all was for 11 miles and only had radio on when all the dash lights flashed up speedo and revs drop to zero display blank and then all came back on. Trip computer reset itself to zero.
So turned radio off and drove for 20 miles not issues at all with no load anywhere happened again. so tried loading up electrical system interior fans on, lights on using cruise control on,off multiple times increase/decrease speed and nothing. turned fan down to 2 then after a few more miles it started again this time doing it 2 or 3 times in succession than nothing. got home all display working, menus etc and engine fan all good.
Could it be the sam unit under the fuse box and if so can I do a direct swap with another unit.
thanks in advance.

Have got the car booked in with an independent specialist for a diagnostic check £90 and will go from there.
i had the instrument cluster out today and can get the display going on and off etc while stationary so think it may be the cluster is faulty. Ordered up good 2nd hand unit so will see what happens.
diagnosis isn't until the 19th so have got time to test cluster. I will post up results when known in case others get the same problem.
