Front/Rear Bumpers

2: A weak battery will also give the break pad warning light. Keep the break pressed while you start the car.

In reply to your brakes question, I think they only have the sensors on front..

The inner brake pads maybe worn down and the outside ones fine.

Last two times I've had the brake warning light over the 3 years I've owned it, it turned out the inner pads had worn down. The outer brake pads looked like they had loads of life left.

I have fitted the DIS stalk on my Avant sport, as James says its quite easy to do but you will need vagcom for recoding. Also if you are looking for a secondhand stalk make sure you get one for an avant (has 2 wipers symbols) as the saloon one does not have the rear wiper function. Also look into fitting the washer fluid sensor into the bottle when you do this and wiring it up (cheap and easy to do) as when you add the DIS stalk you will get a screenwash empty warning unless you either fit the sensor or ground pin #1 on the instrument cluster.

For the brake pad warning mine went off with about 5mm of pad left, the sensor wires that trigger the warning are not buried very deep in the pad. Its either they are low or you have a broken wire somewhere. An inspection of the pads will show if the sensors have been starting to be exposed and worn away.

With the Votex kit James is also correct, the front and sideskirts are the same for both avant and saloon but the rear is different as the side length to the rear wheel arch differs between the two body shapes. Also if looking for a votex rear be aware the bumper comes with 2 infill panels allowing for different options for exhaust exits. These infill panels can be bought as either 'with exhaust' or 'without exhaust' for each side of the bumper allowing you to have no exhaust showing, 1 showing or 2 showing.

Another way I assume you can check if the RS6's are reps or not is to pop the centre caps off and see how many mounting holes the wheel has. Most reps have 2 sets of holes (10 in total) to allow them to fit both 5 x100 and 5 x 112 bolt configurations, and I assume genuine wheels would only have one set of holes.
