Valvetronic and rev counter issues
 

Hi
I've a 2008 Cooper with 72000 miles. I bought it cheap with a few issues but could do with a little help sorting it out. I've scanned for codes and got the following
2868 Valvetronic servomotor sluggish movement
285E Valvetronic adjustment range
2847 Valvetronic servomotor electric
28B4 Valvetronic sluggish

The final code I have is 5DF7 Interface:instrument cluster signal error.

Any help is gratefully received.

I also have issues with the rev counter service display, the service indicators have no mileage or dates on them just dashes
There's also what looks like a first aid sign beside the mileage
