OK I normally take my A4 to the specialist I use to get it serviced and MOT'd at the same time. Only done 5k miles this year in the quattro, so decided to just take it to a "while you wait" place nearby as it runs out today. They failed it for "seriously damaged left/right front brake hoses", claiming the vehicle is dangerous to drive. I was furious so immediately took it Autotechnik who'd recently replaced the control arms, and should have spotted the serious damage to my brake hoses. They put it up on a ramp and showed me the serious damage. They couldn't believe it had failed for this reason and should have been an advisory at most. There are very tiny cracks on the caliper ends, which I couldn't even see when I first looked. There were at most half a millimeter deep if that. They said pretty much all hoses look like that after a while and that the hose itself is double skinned anyway and the side walls are about 5mm thick. Dangerous to drive my arse. So anyway I replaced them tonight £12.50 each and will be getting a retest tommorrow, then once they've passed it a serious amount of verbal abuse. When you think of the shitboxes you see on the road everyday it just makes me mad!
