Ok final update:
I use the car for work and have been off the road since Friday.
Told them i was not going to pay £202 for a repair that they may or may not have caused. Settled on £167.00 and get it back today.
Not ideal, but better than getting the car back and having to order a part that will take a further day to arrive and the hassle of fitting it myself or finding an independent to fit for me.
Thanks all for the advice.
