You can easily test this by disabling it by unplugging the connector cable. Or it may be the torque converter lockout acting up - does it happen only in "E" or in "S" and "M" also? ABS light staying on can have multiple reasons. Most common is a broken signal cable from one of the sensors. Or it could be the fuse for the ABS ECU. Or one of the sensors is defective... As for the sound - have you checked for loose things underneath the car (cat heat shields etc.)? First thing to do is checking the fault codes stored in the engine/transmission ECU. You can have that done at any Audi dealer or do it yourself with a laptop, VAG-COM software and interface. Read here for more. Post Extras
