Broken EGR cooler bolt in exhaust manifold, Help!!

[dutch724]

Bought my 09’ X5 Diesel in June 17’ at end of July had the EGR Cooler replaced by the used car dealer we bought the car from. By Oct 17’ began smelling exhaust fumes in the cabin. Bought an extended warranty hoping to take care of the issue once we were allowed to make claims in Feb 18’.

BMW dealer takes a look at the issue and finds one of the EGR cooler bolts broke off inside the exhaust manifold. Someone (assuming it was the used car dealer) drilled a small hole in the broken bolt and stuck a trim screw in there to try and hold this EGR Cooler to the exhaust manifold. The BMW dealer of course told me this is not covered under the extended warranty.

There was an option of taking the exhaust manifold off and replacing it, but that would be a $4000 repair.
There is an option of taking the radiator and condenser out and that would get you a straight in angle to drill the bolt out and retap the threads. That is most likely the path I’m planning on taking.

Looking for any advice that I can get. What do I need to know about pulling the radiator and condenser?
I imagine the condenser I might be able to push it out of the way once the radiator is out. Please correct me if I’m wrong.
