ISSUE

Customer may report an unusual engine noise/loss or performance and illumination of the MIL lamp on the instrument cluster.

CAUSE

Investigations have identified that a number of Variable Valve Timing Solenoids have not been manufactured in accordance with the required specification and will cause the failure modes reported.

ACTION

All retailers following a customer complaint with the attached DTC's recorded are to replace the appropriate Variable Valve Timing Solenoid (LR073778) and check etched date on the new part. If the manufactured date is prior to 180823xxxxx (23rd August 2018), do not fit  to the vehicle and order another valve.

NOTE: Replace Variable Valve Timing Solenoid (follow TOPIx procedure within section 303-14B: Electronic Engine Controls) using only new parts with a manufactured dated on or after  180823xxxxx.
