I'm bored, so I thought i'd test the knowledge of the motors crew a little. I expect any testers or mechanics here to get this one relatively easily, and I also expect a few trollers adding pointless views on whatever.
A EP3 Civic Type R and a BMW E46 M3 are both presented for an MOT with the same fault, the BMW pass's with and advisory and the Civic fails. The part on both cars is defective in exactly the same way and to the same degree.
Why did the BMW pass but the Civic failed? Can you guess the failure?
*note the civic did not fail because it didn't have the torque to climb back out of the brake rollers* 
Will check back in the morning.
