I retrofitted a MFSW to my A3 today as it didn't have one. I also fitted a new control module with the ability for MFSW and cruise (which is also fitted and working). I've coded the module according to the table in VCDS but the buttons do not behave as they should.
Steering control module is 8P0 953 549B HW ver. 021 SW ver. 0050
Slip ring is type 2 I believe
- Volume scroll does nothing
- Volume scroll pressed in reduces the volume.
- Scan scroll does nothing
- Scan scroll pressed increases the volume.
- Mode button starts frequency search upwards
- Speech button starts frequency search downwards
