Warning lights on

[Stubert75]

HI ALL , I'm new to this forum, I have a 2017 A4 B9 2.0 diesel and it has just thrown up a load of warning lights on the dash.ights on are ABS, stability control tyre pressure, air bag , cruse control inop , audi sense limited. Auto headlights inop.

Any one have any ideas what to check, I did think it could be a batter fault but the car is not in limp mode and drives fine I have ordered a new diagnostic tester but don't have that !

Get a free battery test at a local Halfords. If it's low it has been known to cause systems to throw fault codes up as a result. Check for water in the ECU box as well, which should be under the scuttle pannel on the driver side nearest the windscreen. Couple torx screws to undo it, just make sure it is seated probably and tightened when refitting.

Do a fault code scan, but could be something to do with ABS wheel speed sensors as all of those systems depend on wheel speed data to work.
