Test drive reveals a couple of concerns
Posted: Sun Feb 19, 2017 11:46 am
Went to view another B8 S4 yesterday. Really nice car, and ticks all the boxes for me.
However, there were a couple of problems which meant I had to walk away. First up was the brakes. When at motorway speed, I had planned to brake heavily to see if there was any instability or shake, but before I managed to apply a lot of pressure, the wheels felt as though they had locked up briefly, as if the ABS kicked in(and I'm sure the pedal sank down), but I had only applied moderate braking, maybe 15-20% pedal. No ABS codes other than a tyre pressure warning which popped up.
Are there any known brake issues? Or any ideas what could cause the ABS to kick in like this?
The other is related to S-tronic, but this one could just be in my head. When we went over some speed bumps (so going slowly), when I accelerated away it seemed to kick down to 1st a second or two after pulling off, despite thinking I wasn't applying much throttle (had our 5 month old baby on the test drive). Other than that, the gearbox seemed to behave well. Wasn't sure if this could be a warning sign of the S-tronic wanting to throw huge bills my way in the future.
