The intake manifold flap regulator stop (limiter) on VAG 2.0 TDI CR engines with the plastic manifold 03L129711AG prevents the regulator arm from over-travelling and breaking. When it wears or breaks, the flap regulator arm contacts the manifold housing directly — causing damage and incorrect flap positioning. This replacement stop restores correct flap travel limits.
