how much will it cost to repair cylinder misfire causing by low compression on one of the cylinders?

I am a new member in this forum. I really appreciated any helps that can given to my Audi A4 car.

Recently, I found out my Audi A4 2008 car start to shake when the car is parked or stopped at the traffic lights. The shake became really bad even when I am driving it, so I took it for a professional diagnostic service. From the test report, it said the cause of shaking is because of misfire on one of the 4 cylinders, the cause of misfire is because of low compression, and I was told it would cost over thousands to repair it. 

I am reluctant to  pay over thousands for the repair as it is a 10 years old Audi (although still drive beautifully). The other option I am thinking of is to trade in for another Audi. I want to know has anyone had the similar problem with the misfire? and realistically how much will it cost for repair? Is there a good, reliable and honest Audi specialists in Gtr Manchester area? 

Thank you so much if someone can advise me on this?

My advice be would be to get advice from Audi independent specialists then you'll know exactly what costs to expect.
