Do you know for sure that the cluster is not faulty? It's just I have read through the other post you made and this one, and can't see anywhere where it states that the cluster is definitely not faulty (might be there but I can't see it).
That is a lot of money to go spending on a vehicle to find it still hasn't been fixed. I can tell you from personal experience from the wife's van though that the diagnostic equipment that garages use do not always point directly to the cause of the problem.
Our van would run really rough and lose power at random times. We had our mechanic (who is very good) put it on the machine and it threw about 20 error codes at him, and to be honest it was almost a case of starting at the lowest cost fault and hoping that would fix it (which it didn't), and then work our way through the error codes from there. The problem sometimes is that one thing being faulty can throw other things out (or at least it appears that way).
