Instrument cluster suddenly died
Hi Kristian Thanks for the update, to my thinking the fact it seems intermitent would point to a Dry Joint or a cracked/broken wire feed or track on the Ribbon Dave -

Afternoon Karl Welcome to the Forum There is a Register of BMW Specialists Google/Siri will help you should be able to locate one not to far away from you. Before spending your hard earned here are a few of things to check (1) Check Battery Voltage at the charging points under the Bonnet engine off, it should be 12.5v anything below that indicates a failing battery which can cause all your issues. (2) Check the Voltage at the Charging Points engine running voltage should be 14.5 + Volts anything lower points to an Alternator/Voltage Regulator issue (3) BMW love multiple earth points the mounting for these can often become corroded check earth continuity or simply undo the mounting bolt clean everything apply electrical contact cleaner and bolt it back Reset all Fault Codes and check to see if any come back Dave -

Instrument cluster suddenly died
I have still not found the cause of the problem, i havent tried to diagnose it yet because lack og time, but when i was traveling in the holidays suddenly the cluster started working. But then the next time i turned the car on it didnt work. Now it has been working 20% of the times i turn the car on. The other 80 it is Dead as i described. I think this makes the problem even more complicated -

Morning All, I have a 2004 645ci that only has 50k mileage on it and is in generally very good condition. (I drove it to Germany last summer without any issues) Recently though I have been getting a host of error messages flash up (Dynamic Drive fault, power steering etc) When this happens I lose power steering and gearbox becomes very clunky and wont change above 3rd (this happens soon after start-up) I have had all these errors cleared with a local mechanic but looking for a specialist to diagnose whats causing it and maybe it needs its "brain" replaced as I hear this is a common problem in these older cars where the tech was very new at the time. Many Thanks Karl
