They are saying they will repair it BUT they won't fix the calipher, the dealer says the calipher would be the cause of the problem ironically enough. 

I thought it was a REAR caliper that was sticking...?

Yes it is, so I don't really think that would cause it but he said thats where brake fade comes from. 

This guy is either a clueless halfwit or taking you for one.

Possibly both. Probably both.

The situation gets even more complicated, as I've just discovered a recall was issued for this vehicle model and year in the US for this exact same issue. But no recall issued in the UK https://www.autoblog.com/2013/09/28/bmw-3-series-5-series-x1-x3-z4-brake-recall/

"The problem has been traced to restricted oil supply from the intake camshaft to the brake vacuum pump, which may cause the brake vacuum pump to fail, resulting in a loss of power brake assist. While the hydraulic brakes will still function, the driver must much apply greater pedal pressure and the distance required to stop the vehicle will increase."

No, that is not your issue. Not if it does it occasionally, then is fine.

That's an engine lubrication problem causing the vacuum pump to fail terminally. Pressing the pedal harder stops the car, because it's simply a lack of vacuum assistance.

The recall was on then-new cars, eleven years ago.

People on the forum though saying it's intermittent?

When the vac assistance stops working, you will have a VERY heavy brake pedal, regardless of road speed.

I can't see how a vac pump that's failed because of lack of lubrication is going to fail once, then start working again, then stop a few weeks later, but only briefly...

And the affected vehicles will have had the problem a decade ago, not now.

Alright 
I took the car to the dealer, main man wasn't there his colleague was.
He said the grease could be "washed off" at a car wash which I thought was bullsh1t but I needed a free car wash anyway.

Went back to the garage he ran OBD, tons of errors one relating to ABS, but he cleared them, i drove again, error went away. 

He then told me everything i would be fine i was like no, get your mechanic to check.

mechanic checked very low brake fluid, that was replaced.

brake discs and pads lookd fine but then i saw the pictures the garage had sent over and they looked awful and a jetg wash isn't going to have changed them, so now i'm not really sure what to do, as it seems like the dealer is unwilling to resolve the issues and is just blatantly lying

Ok so where do I stand with this 

TLDR 

Car has intermittent problems with brakes. 

Independent garage has identified 3 faults with the brake system which could be causing it. Fault has been attributed to incompetence /neglect in installing new brake pads. 

Dealer disputes diagnosis. Dealer claims there is nothing wrong with the vehicle. Dealer has only fixed one fault (low brake fluid - the mechanic bled the system and replaced it, only upon me insisting on it mind you) . 

I have asked the dealer will he still at least provide me with the replacement parts as initially said, dealer hasn't responded for several days. 

Brakes are usually wear and tear but as the poor condition of the brake pads can be attributed to negligence by the mechanic used by the dealer in installation I believe that would override any claim it's wear and tear. 

Do I have a case to ask the dealer to repair the car or be subject to the small claims procedure? Itrespective of whether it's the cause of the issue, a fault has been identified and the dealer is not appearing to entertain the idea of fixing it

Honestly at this stage you can ask for what you want but the dealers (in)actions should give you an idea of whether a further threat is going to change anything

If you want to keep the car then take it to a specialist and have it repaired knowing that you won’t then have to repair it again in the coming months/years

And for future is you want less risk then either have an independent pre-purchase check carried out or buy on one the Approved Used schemes 

Sometimes life’s too short to chase perceived injustices

Next time consider an AUC.
BMW AUC (Approved Used Car) scheme gives a one year warranty, which can be extended, and covers even more on the warranty than buying a new BMW.
It even covers wear & tear up to 100k miles.
I wouldn't even consider buying a BMW, Mercedes-Benz, Audi, or Porsche , without a genuine manufacturer's warranty.
