Description
Extremely rare and difficult to find, Scirocco Brake Check Valve for Vacuum Brake Boosters. These were very difficult for us to find. We sourced these directly from the OES European manufacturer. Restore your Scirocco with this Genuine OES ATE – Non Return 16v Brake Check Valve for your brake booster.
This check valves attaches to your vacuum line, between the brake booster and your intake manifold. Also, this comes with the 8v manifold connector hose / 16v Brake Booster Connection, and ring clamp (#9 on 8v diagram). The replacement 90º booster elbow connector, can be adapted to a 8v to rerout or repair entire line. Pipe / hose conversion hose is not included
It has taken us over a year to find this Genuine OES supplier for this part. There are super hard to find and not cheap, even for us to source. We can only get a few at a time due to rarity and the cost to ship from Europe. Luckly, we have them. If we have none in stock, you can still order. However, it may take a weeks to get back in stock. If inventory is low or out of stock, rest assured there are more on the way and you can still available to order until they arrive.
In conjunction with a new Vacuum Check Valve, it will improve / restore your vacuum system. These are used to keep the vacuum retained in the brake vacuum system until vacuum is needed. Even with the engine off. Overtime these will wear out and stop holding pressure.

How to Diag a Scirocco Brake Booster Check Valve
To check these valves, Check with a vacuum testing tool. If you are brave, simply suck tough each end. If pressure can be sucked though both sides, the valve is bad and needs replacement.
Used in the vacuum system to control the brake booster, HVAC & EVAP systems. If you have idle issues, this may also be faulty on your vehicle. Also, check the vacuum connector hoses. Furthermore, if your line connectors look ‘ok’, they may still need replaced. Before letting the system fail, vacuum check the entire system. You will be able to determine if they are in fact leaking. We use a Mityvac MV8000 tool to test this.
