2nd SUPPLEMENT: Technical Campaign: timing chain tensioner (Date: 10-2016).
– C 600 Sport (K18, 0131/0132)
– C 650 GT (K19, 0133/0134)
This BMW Motorrad Service Information Bulletin (Recall 14V-264) concerns the C 600 Sport (K18) and C 650 GT (K19) scooters. It reports that the timing-chain tensioner may wear prematurely due to a manufacturing defect, potentially causing the engine to stall. BMW replaced it with a hydraulic timing-chain tensioner starting June 2016, and this new part must be retrofitted to all affected vehicles. Dealers are legally required to complete the recall before delivery or service. The document specifies repair procedures, warranty codes, and part numbers for the replacement.
