The could not fix the problem there and then and advised me that I needed to bring the car back so their specialist electrician could look at it - at £109 per hour! I will be taking the car in next weekend and hopefully they can diagnose and resolve the issue.

After reading Dimitre12's post and a few others regarding this issue, I'm wondering/hoping if it could be a faulty Brake Light Switch. How would I test this? The brake light goes on fine when I press the pedal - is there something more I need to eliminate this as the issue?

Tyre pressures are fine and I have a new alternator.

Is this a speed sensor failure as mentioned earlier in this or a similar post?

Sometimes what is required is to read the shop manual and individually test the components that may be at fault.
To do this one would need to have a digital multimeter that can measure accurately small currents and resistances.
These days this seems to be beyond many dealerships, they prefer the basic 'Shock and Awe' method of replacing all components that could be faulty in the hope that one of them cures the problem.
You naturally have to pay for the components that did not need replacing and often the new components did not cure the problem anyway .... so sorry says the dealer as he counts his profit.
In situations like this you must demand all your replaced components be returned to you. You paid for perfect parts to be needlessly replaced and they are yours. If left in the dealers hands he could easily sell them in the next job and repeat the scam.
It is your right to see all items that are listed on the bill as replaced.
