Slipping Clutch Meaning
The phrase slipping clutch means that when the Golf’s clutch is fully engaged there is not enough pressure or contact surface left to transfer the force from the flywheel to the transmission. This can happen for a variety of reasons (the most common being that the disc is worn down).
What Happens When a Clutch Slips
When there’s too much force coming from the engine for the clutch to handle, it slips. Slipping feels like you’ve pressed the clutch in a bit and the RPM’s shoot up, even though you haven’t pressed the clutch at all. The natural reaction is to let off of the gas, and the RPM’s will go back down and the clutch will re-engage.
Golf Slipping Clutch Causes
Think of your clutch like a giant brake pad. While it is very likely that it will outlast a set of normal brake pads, it still does wear down. When it wears all the way down to there is no friction surface left. At this point, the clutch can no longer grip the flywheel properly, even though it still has pressure put on it from the pressure plate.
New Clutch Slipping
A new clutch can slip for a variety of reasons. The most common one is that the old flywheel was reused. It can also be due to a fault in the release system.
