Hi, I took my 2015 A4 Allroad for it's first MOT today, and the tester was going to put it on a two wheel rolling road brake tester. As I thought about cogs and drive shafts exploding, I told him that wasn't going to happen, as it's four wheel drive. He asked if it was permanent four wheel drive, to which I shrugged my shoulders, but thought in my head "no" ?? In the past he had checked my 2009 A3 TDi Quattro out on the road with a decelerometer, so thought he would be doing this with my A4. Soooo.......to get to the point......could he have tested my Allroad on a two wheel brake tester ?? Cheers, Graeme.
