    2004 Audi A8L Power Steering (Servotronic?) diagnostics

    Good Day Folks,

    Has anyone seen or knows solution to diagnose and repair below symptom?

    Every few times I drive, the power steering assist feels like is on and off during making a turn. It feels stiff, cuts out, then releases with a bit of force then cuts out again as per video below. There are no abnormal noises from power steering, fluid level is at max, no air bubbles in the tank and no leaks of PS fluid. The fluid is Audi OEM. I did VCDS scan, cleared DTCs, no change.

    It does that sporadically, I can drive with no issues, and then it suddenly will start malfunctioning. I drove car 7 times today, it did that on last drive, otherwise everything was functioning normally.

    I tried to find as much info as I could on this topic, I suspect (don't have evidence yet) is that power steering assist is switching between highway speed setting and actual speed setting. One way this could be happening is when solenoid valve N119 would be malfunctioning by either getting incorrect speed signal, being faulty or have wiring issue. Below is quick video of the valve I am talking about. In my VCDS I wasn't able to locate this valve. Does anyone know where I could find it?

    That scan has a boatload of intermittent faults. That makes for a low signal-to-noise ration. Please clear all fault codes from this car, and post a fresh scan. Then drive it until the problem occurs again, and make another full scan.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Hi All Forum Members,

    Update with my 2004 AUDI A8L servotronic symptoms.

    Strangely, the issue went away on it's own, I have been driving few times a day for over a month and it was becoming less and less noticeable until 2 weeks ago when it completely went away.

    My observations during experiencing this symptom:

    Every morning or after the car was parked for few hours there was never a problem.

    It was only occurring after driving when car warmed up and parking the car, then starting up again within few minutes to an hour. I tried shutting it off and starting again on multiple occasions to see if I can "reset" it but it never did anything, the symptom was always there after car warmed up and parked.
    I felt sometimes steering wheel was extremely light throughout whole driving time including highway, or tougher than usual.

    Again, the issue hasn't happened for few weeks, I don't want to speculate what that could have been but I haven't really done anything other than clearing all of the VCDS codes which initially didn't change anything.

    Keeping my fingers crossed!
