I feel like i have been seriously bent over now...... MoT failed on my ABS light deciding to make an appearance during the test. I had previously had a VCDS scan and the Longitudinal Acceleration Sensor came up with an "implausible signal" fault......so, after finding out the price, i decided to chance it. no luck!!!! and now....Audi have just charged me £133 for a new one..... GUTTED!!!!! has anyone else had this prob and managed to fix it without buying a new one? i tried unplugging and plugging back in but had no effect!!
