VW Tiguan AdBlue Problems — Diagnosed & Fixed
SUV · 2.0 TDI EA288 (Mk2) · 2.0 TDI evo (Mk2 facelift)
The Mk2 Tiguan 2.0 TDI is the VW SUV we see most for AdBlue work. Post-DieselGate software runs tighter NOx thresholds, so a downstream sensor at 70k that would have passed pre-update will now trip P229F and a restart countdown.
Tiguan owners typically see 'Refill AdBlue: no engine start in 900 miles' on the cluster and discover the local indie can't code the replacement. We do — ODIS coding included.
