    It's on the passenger side of the gearbox. 5 min job if you have a ramp.

    You sure it's the switch and not broken wires at the plug end as that is a common fault with VAG cars

    The plug at the switch end.

    The vibrations and engine movement over time break the wire internally really close to the pins in the plug and an early sign is flickering reverse lights when revving the engine.

    It's actually quite rare to have a broken reverse light switch as the mentioned wires a the main culprit.

    Should be able to mate, but use axle stands...........small ramps would be better if you have access to them.

    The switch is located on the passenger side right above and about 2 inches behind your inner CV joint.

    It may vary slightly from gear box code, but gives you a rough idea of location.

    I know this is an old post but needed this info myself the other day so here goes:

    On my one (A4 B6 1.9Tdi 2003) the switch is accessible from the driver's side. (I've got a feeling that the pics earlier in this thread may be taken from another thread on different forum which I believe features a left hand drive car as the position of the fuse box appears to be a mirror image of mine). Therefore the reference to passenger side above might not be correct? I appreciate it may differ depending on what gearbox is installed.

    Anyway, on my car I needed to remove the airbox. Then stuck me head in the gap and peered as far back as I could (as per pic below).

    The switch is a nightmare to access and I couldn't get a screwdriver in there to unclip the wiring. In the end I taped an allen key to my thumb so that I could hook it onto the plastic clip once I'd stuffed my right arm all the way into the engine bay. Got the clip off and that solved the problem of the reverse lights staying on. However, it does leave you with no reverse lights at all!

    Not sure how the hell to get the actual switch unbolted from the block. Its a nightmare getting any tools in that far. Probably easier just to fit your own microswitch to the actual gear lever and wire it in to the electrics!! Not, perhaps, what your local Audi technician would recommend though.

    Anyway it started raining and was getting dark so I've given up trying to get the switch out. If anyone has any suggestions... that don't involve dropping the box out or removing the exhaust manifold... then please let me know. : )

    Mine too was on the drivers side! 1.9tdi quattro. 2004.
    Changed it recently. I found it easiest to get at it from underneath having removed the rear under tray. You'll need a large spanner, I think something like 22 or 23mm.
    My switch had a broken return spring, so the reversing lights just stayed on.
    There are a couple of different switches so double check you have the correct one. Mine was also listed against RS4's and R8's but was the same part as mine.
    I used Audi PN 01E941521B. This is a two pin connector with long connector body. ETOS listed 01E941521A against my car but they are both the same part.
