Reviews of OEM Volkswagen brake booster

The rebuild kit for the brake booster came in today so that went back together... all the parts: the kit with 3 o rings, pump cover, pump innards, and pump body.

Its NOT the Brake booster vac pump lol I replaced that 3 months ago with OEM VW parts from the dealer $506 repair.

Just to update - my 2014 GLI is currently in the shop. The hissing is due to cold weather causing a seal to \"shrink\". Boost is always regained after startup, so it's not a \"safety\" issue. With that said, they've ordered the report to replace the brake boost.

Just for follow up.. I brought the car to the dealership this morning. They were able to replicate the issue and it is the brake booster.

That brake pedal noise is a vacuum leak. Either the line going to the brake booster or the brake booster itself. They are known to cause leaks. Get it replaced ASAP! I got mine replaced. Same issue. Hissing sound that goes away when slightly stepping on the brake.

I found a vac leak at the brake booster line. I fixed it, and now I am getting no codes at all. it says "EVAP OK" The reason I missed the leak at the brake booster line is because it can't be detected with a pressure test because of the check valve. I've driven 35 miles with no codes, so an entire year with a lean code is finally over, I hope!

My car's water drains clogged and the brake booster was saturated and needed to be replaced. Brookline Volkswagen Audi charged me $848.33 to clear the drains and replace the brake booster.
