I have. 2000 a4 avant 1.8t
Car seams like it's in limp mode on the highway
It's an automatic(tiptronic)
I have a solid abs light on and a flashing brake light on. Most common cause of this is a bad abs module from what I've read. I'm wondering if the computer is putting the car in limp mode if it thinks that brakes can't stop the car sufficiently. It runs perfect in 1st and second gear. 3rd is iffy and almost no power in 4th and 5th. It will NOT go past 80 miles an hour.
There are no boost/vacuum leaks. New diverter valve installed earlier this week. Computer is throwing a code for "rough road detected abs"
Can those lights/module be causing this in an automatic trans a4?
