Problem addressed in warranty that continues after warranty period - what can I do?

My recently purchased BMW (08) has developed an engine sensor and injector fault. Dealer has approved repair, but should other items such as coil also be fitted? If they are not, and the fault happens again outside warranty (one month of three month warranty left) where will I stand, please?

The dealer is liable for any fault that could have been present or developing on date of sale for 6 months from date of sale. Nothing to do with warranties.

My Renault Clio is still under warranty and needs new brake pads. Would having the work done somewhere other than a franchised Renault dealer invalidate the warranty?
