    hello guys ive just brought a 2004 audi a3 2.0 tdi there are a few niggly bits wrong with it main one being it could need a new power steering rack or pump a backstreet garage has told me?.

    steering wise when im driving and taking corners the steering wheel does not become tight or stiff at all its really light as it should be i could turn it with my little finger.

    however the issue is after taking a corner and putting my foot down a little bit, unaided the steering wheel should come straight back to self center as (i have previously owned a a3)

    with this one it will self center a little bit but its asif i have to guide it back to self center so i will be going in a straight line.
    but the steering has no heavyness tightness at all throughout, i have just had the tracking done today specifically to try and fix this problem and its still the same.

    the esp light is on the dash

    the car has been sitting for a few months without a battery etc connected

    can anybody help me out please, could it need resetting on a vcds for the steering angle sensor?, or will it need a new rack or pump please feel free to let me know and comment many thanks ben

    If theres a light on the dash you need to get it scanned for a starting point tbh.

    At an absolute guess I can't see it needing a new rack or pump, as if it turns as expected then the mechanical side of it would appear to be working. You may be onto something with steering angle sensor, as the steering is electro-mechanical I believe? Which may mean it doesn't detect the need to release the tension on the steering and allow it to spin back to straight.

    This is all complete guesswork so far!

    Where abouts are you? May be worth looking at the VCDS map to see if anybody nearby could lend a hand for a few beer tokens?

    A member off this forum should be willing to do it for a couple of beers. Have a look at the VCDS map, I've not got a link as currently on my phone.

    Taking it to a garage is likely to cost 50-70quid for a diagnostic scan.

    It's in the steering column I believe, somebody with more info will be along now you have an error code.

    I suppose the good news has to be that the steering angle sensor must be a cheaper fix than a rack/pump!

    Edit: more info here 00778 - Ross-Tech Wiki

    have you read this? on that link you sent me

    This Fault Code may also be stored even though the Steering Angle Sensor (G85) is properly calibrated (Basic Setting), though it may not be finally initialized yet. Check the Measuring Value Blocks (MVB) in the Steering Aid Control Module (J500 / #44) for details. The Initialization will usually take place during a test drive.
