Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2015-2016 Jetta, Beetle, Beetle Convertible, Passat, Golf and Golf SportWagen vehicles. In the affected vehicles, the camshaft lobe that drives the brake vacuum pump may shear off, resulting in a loss of brake assist.

The official release was November 4th, 2015 affecting 92,000 cars: VOLKSWAGEN ISSUES VOLUNTARY RECALL : Volkswagen US Media Newsroom

CONSEQUENCE:
If the camshaft lobe shears off there would be a loss of brake assist, lengthening the distance needed to stop the vehicle and increasing the risk of a crash.

I'm wondering how many people have actually had the problem.

VOLKSWAGEN ISSUES VOLUNTARY RECALL

Herndon, VA - Volkswagen considers the safety and satisfaction of its consumers and passengers a top priority. As such, Volkswagen has notified NHTSA of an upcoming voluntary safety recall affecting approximately 91,800 vehicles with a 1.8T or 2.0L gasoline engine from the 2015-2016 model year. The models involved are: Beetle, Beetle Convertible, Golf, Golf GTI, Golf SportWagen, Jetta and Passat.
The recall affects approximately 91,800 model year 2015 and 2016 Volkswagen Beetle, Beetle Convertible, Golf, Golf GTI, Golf SportWagen, Jetta and Passat vehicles in the U.S. On some vehicles, the rear camshaft lobe has the potential to unexpectedly shear off from the camshaft. If this happens, vacuum pump power will be lost so that the pump will not deliver further vacuum supply to the brake booster, and reduced engine power will cause the Malfunction Indicator Light (MIL) to come on. After depletion of the vacuum reserve, braking effort increases. A reduction in engine power and/or increased need for braking effort after vacuum reserve has been depleted while driving can increase the risk of a crash.

At no cost to customers, authorized VW dealers will repair the vehicle if it is identified as having come from one of the affected production lots.

No injuries related to this issue have been reported. Volkswagen will notify all owners of affected vehicles and will instruct them to arrange for an appointment with an authorized Volkswagen dealer.

@Genos2 =???? what does your post have to do with this Sticky?

My buddy at work has an affected model, the current warranty repair is reprogramming the engine to reduce startup stress on the sintered cam lob driving the vacuum pump.....seems suspicious, but technically it actually makes some sense. Google about the application of sintered cam lobes and it will become a little easier to believe the "fix". I think on some websites like Carcomplaint.com there was a link to an article that indicated the failed cars suffered infant failure (meaning very early in service life of vehicle); in the cases where the cam broke - obviously VW was pulling valve covers and swapping out to a new cam....I think this same sintered cam on the rear bank is also driving one other accesory pump - the fuel pump...so this cam shaft and lobes are seeing some dynamic loading based on engine programming....VW claims the reprogramming aides in reducing the load on the suspect lobe by changing the way the fuel pump is utilized.....only time will tell if their fix actually works. I can relate, I am an engineer and this is what would be called an "intermittent" failure....not easily reproduced, and just throwing away a sintered cam in favor of a cast/forged solid cam is actually a very tough redesign....sintered cam lobes are often more customized in their shape vs the cast/forged solid variety.

The true fix is to avoid any vehicle where development engineers have seen fit to drive anything except valves off a camshaft...

Fuel Pumps, Brake Vacuum Pumps, ... what's next? a camshaft driven auto-pilot?!? :hmmm:

:banghead:
