A4 ABS Light is on..

I have a 99-2000 model A4 1.8t Quattro

I know there is apost on here about this but i couldnt find it.. lol.. yes i am a retard.. haha.. anyways the ABS light and the red light with the exclamation mark is on on my dash.. How do i reset the ABS and if i do will the red exclamation mark (dont know what that is) go away?

Also want to put 4 10" subs in the boot, but heard there was a vaccum control module and other **** in there,, will they be affected?

You'll need a VAG COM or code reader to reset the light.

It might be on because you're ABS/BRake PAd Sensor are bad.

same thing happend to me. shop veriefied i need new sensor 200 bucks :(

Funny how you think the solution is to just reset it...??? The light probably came on for a reason, if its your ABS light that usually means your ABS unit is dying/dead. If it were your pads youd have the brake pad light on looks like: (0)
Oh yea a dirty pad wear sensor may cause that, the solution normaly is to just clean it.

Or if your unfortunate like me you'll need a new ABS control module, dealer wants $1540 ha! Run a diagnostic and see what fault codes you get, hopefully its just the wheel speed sensor.

righto, where is the sensor located if i need to clean it..

There are 4 sensors one in each brake caliper. Tap each caliper with a hammer to clean brake dust.

There are 4 wheel sensors,one on each of the uprights.

It could have come loose, have kinked wireing, gone bad, or got dust in it. They can be hard to pry out.

They are NOT on the brakes... unless you re talking about the brake pad sensors, those are on the pads.

ABS light could be a bad sensor, a bad cvjoint (wheel sensor section) , a dirty/misallinged sensor. Usually a bad ABS control module is ABS light w/ a blinking brake light. (atleast for my MY)

A new sensor i think is like $120. Easy to replace yourself as well.

you cant reset the ABS ecu like the car computer, when you sort the problem the system resets automatically check the fluid level but I think its a speed sensor

I am having this problem i think.  Blink abs light and an annoying beep beep beep beep sound that happen every so often.  funny thing is it used to beep a lot last week. now not so often.  insite.  I found a rebuilt abs control module for 199$  but i want to try all the cheaper solutions first
