    Take the guesswork out of Audi/VW 4.2L V8 timing service. This Oni Tools kit includes camshaft locking bars and hall-sensor setting gauges plus a TDC crank pin and chain wedge—everything you need to lock cams, set the sensor rotor rings, and secure the crank at top dead center during timing chain work. It’s an alternative to factory tools T40046, T40047, 3242, and 3409 and is engineered for the 4.2 R-CAT/40-valve V8 used from 2002–2009. Typical applications include Allroad (BAS), S4 (BBK/BHF), and A6 Quattro (BAT); many A8 4.2 engines share these fixtures (verify engine code). Precision-machined, hardened steel delivers stable clamping and repeatable alignment to help eliminate rework and warning lights after startup. Ideal for professional shops and skilled DIYers tackling chain service, cam cover reseals, or top-end work.
