Volkswagen model-specific AdBlue guides
Diagnosis and repair guides for the Volkswagen models with the highest AdBlue fault volume.
VW Crafter AdBlue problems
Van · 2.0 TDI (Euro 6)
Crafter drivers commonly see an amber AdBlue warning followed by a countdown. Repeat faults after a dealer sensor swap usually trace back to missing coding.

VW Tiguan AdBlue problems
SUV · 2.0 TDI EA288 (Mk2)
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.

VW Passat AdBlue problems
Car · 2.0 TDI EA288 (B8)
Passat drivers see the countdown, get a clear-and-go elsewhere, and the warning returns — almost always because the sensor wasn't coded. We do the full ODIS work in one visit.

VW Touareg AdBlue problems
SUV · 3.0 V6 TDI (CR / CRC)
Touareg owners typically see the AdBlue countdown after a tow-heavy summer, get a dealer quote north of £1,200, and find us for an OE-coded fix at a fraction.
