Please note that, due to the publication of the service measure "VS20LALULO" (see SM09.10-S-0014A), the workshop visit check of the tightening torque of the screw clamp (2) fastening the engine air intake duct (1) to the hot film mass air flow sensor (B2/12) is no longer necessary.
As documented in the delivery and handover inspection (see AP00.20-D-1100A), the vehicles must be checked for any open service measures.
The tightening torque of the screw clamp (2) fastening the engine air intake duct (1) to the hot film mass air flow sensor (B2/12) must be observed when removing/installing the screw clamp (2) (see AR09.10-S-8130E).
The screw clamp (2) of the engine air intake duct (1) on the hot film MAF sensor (B2/12) must always be fastened with the specified tightening torque.
Otherwise the engine air intake duct (1) can work loose from the hot film MAF sensor (B2/12) and cause engine malfunctions.
