One problem related to check engine light on has been reported for the 2006 Volkswagen GLI. The most recently reported issues are listed below.
On my 2006 Volkswagen passat the cam follower has worn through and damaged the cam shaft lobe that drives the pump. This is a known issue that has affected many vw passats. It is a safety hazard as it can cause the engine to stall there for if a person is in the flow of traffic it could cause a crash to occur. Volkswagen has issued a TSB on the issue but will only perform this service if the computer shows a specific check engine light and only if still under the manufactures warranty. Volkswagen should at the least be required to inform people that the cam follower should be checked for wear at a regular intervals to prevent a possible accident.
