Rear bumper removal
I ran VCDS on my 2007 Audi A6 3.0 TDI Quattro Le Mans and it showed a fault with No 3 glow plug. Which one is No 3? A second fault was showing for the right-hand outside rear parking sensor. I know people have changed the sensor by shoving their hand up behind the bumper but I couldn’t reach in there.
I have been on various websites but can’t find a definitive guide on how to remove the rear bumper. I tried removing the six screws (three on each side) in the rear wheelarch area next to the wheels. Next, I undid four nuts (two either side) beside the rear lights in the boot and two plastic nuts in the boot that were holding some trim in place (beside what I believe is the battery regulator). Last, I removed a number of screws underneath the car. I pulled away the bumper (at 90°) from the rear quarter panel, where I had removed the first lot of screws (and broke some sort of plastic clip in doing so), then went around the back and tugged at the bumper, but it wouldn’t slide backwards and away from the car.
Do you know if I missed some bolts/ screws somewhere? Dave Spinks
Standing at the front of the engine, No 3 cylinder is the back cylinder on the left-hand side of the engine. The cylinders are numbered 1, 2, 3 from front to back, then start again at the front at the right as 4, 5, 6.
If you had correctly pulled the side sections of the bumper away from the body, this should not normally have broken any clips. The bumper fixings are all as you have described as having been removed.
The only thing you do not mention is disconnecting the sensor wiring loom. If this is still connected, it will impair the removal of the bumper. The plug for the loom should be by the left-hand rear lamp cluster.
The bumper cover can be quite flexible upon removal, so getting an assistant to enable both sides to be lifted off at the same time might help.
