I found this forum looking for a answer to the buzzing noise under the right side of my TL's hood. I'm pretty sure this has something to do with the ABS. My question is, is this common and how do I get rid of this noise? I don't want this noise killng the sale of my car.

 

ABS modulator, would be about $400 to replace

 

is this for a 1st or 2nd gen TL??? im only questioning because your avatar has a pic of a type s...

i thought the buzzing was the abs self checking... doesn't it turn off after a bit???

 

If the ABS light comes on after the buzzing, the ABS modulator is "timing out" due to a failure to pressurize. It could be low fluid, leaking accumulator, leaking internal valves.

More info needed to help.

good luck
