Need help...
 

I have the A6 04 2.7, it drives and it is is great condition, I wanna run something by the experts here.

Problem one, the ABS, and triangle with ! lights come on and off, the brakes were replace fairly recent, don't know if my mechanic damaged a sensor or something he keeps on saying that he didn't but, don't know.

the other problem is that when am driving i feel what I can only describe as random soft pulls like the car is hesitating a bit, if I press the gas it goes away but for some reason, it keeps on doing that, don't know if is something serious or just me being paranoid.

Thanks, for all of your help...

Anybody please??

hi, friend, really sorry to hear that. i think it is the sensor has some problem. The car has both before and after the two oxygen sensors, respectively, in the front and rear of the three catalytic converters, to find the fault in time to be replaced. hope it can help you.

I was leaning toward a gas sensor or fuel pump, will definitely give the o2 sensor a check, whats funny is the check engine light is complete off... thanks for trying to help
