BMW Z4 sdrive23

Hydraulisk ventillyftare som fastnat.

Stuck HVA, BMW refuses to fix.

HVA Bleeding Procedure:
• Check oil level -- correct if necessary.
• Let engine idle at operating temperature with the hood open to verify valve train tapping/rattling noise.
• If a tapping/rattling noise can be heard from the valve train, run the engine for 3 minutes without load at approximately 2,500 to 3,000 rpm (bleeding procedure).
• Then with the engine at idle listen for valve train noises again.
Note: Only listen for noises when the engine has reached minimum oil pressure, i.e. after a waiting period (at idle) of approximately 15 - 30 seconds.
• If no more noises can be heard, the test procedure is complete. No further action is necessary, the engine is working properly.
