320 clk -98 what is the selusion when Bas-ESP-ABS is showing on my display? even the autodrive function is not working. Jesse

the operators manual is clear on that, did you read that first?
it says "get the car serviced" clearly
if you work on cars, do you? thne we scan the systems with the scan tool first. to see if there are complex hard errors.
like the ABS sensors, (not bas) sensor dead. (ops a road hazard hit it and broke the wire there, dang.
then if no hard failures.
first is not ESP (that be last dead last)
the first is , the brake must work perfect if not , the ABS can not
work correctly with bad brakes.
so check fuses.
scan ABS for errors
then do a full brake inspection, takes me 2 hours. but my guess,
youve never done brakes, right,, your self?
not even a full inspection?

1. leaks? (fluid)
2. pads worn out?
3. caliper pistons not sticking
4. rotors not cracked, or wrecked, surfaces.
5. caliper guide pins not seized. (they float free?)
6. emg, brake not sticking on partially?
7. wrong sized tires on car (or just one , omg)
8. ABS sensor parts damaged at axles ends.?
9. bad wheel bearing, seizing or loose.

etc... etc.... and more.

Well you have sensor mounted on each wheel.Must have one or sensor bad.Brake dust can even set them off.

It's probably a faulty ABS sensor /cable on one of the wheels.

All you have to do after replacing the battery and the bas/esp light comes on is drive the vehicle. While your driving around is will allow the steering angle sensor to relearn. That's only if it says "bas/esp see owners manual" displayed on the cluster.

brake switch needs replacement.

with regards of the eps /bas,abs you have to replace the brake switch.

ESP = Electronic Stability Program
BAS = Brake Assist System

ABS--BAS

Most likely cause is the 'stop lamp switch'
It is a electric switch located on the brake pedal inside the car, about half way up on the brake pedal.
Pretty cheap too, I think the switch is only like $25 bucks.
2 connectors on the switch and then it turns out.
hope that helps
Fan relay should be in black box near frewall

hello,good day,try to replaced your brake light switch,this switch have 2 function,for brake light and for esp and bas module,ty

need more info-possible bas diaphragm switch gone bad.does the fault occur as soon as you turn on the car or as soon as you step on the brake pedal??
