So the Carista should have all the functions. Only thing I’d say is the obd2 is cheap enough but watch that subscription at £34 after the initial month free. Still cheaper than a call to a garage. Carista states on the Passat it does ABS.2011 Passat.
Can your fault wait for delivery of a Carista ? Don’t also forget the Carista will allow you “customisations”. I used that on our Yeti, now have dial sweep and mph instead of kph on the mfd.
