Mk1 & Mk2 4mm CIS Vacuum Line
Replace the 4mm CIS Vacuum Line / Hose in your Scirocco with our new vacuum lines. Even if your line look ‘ok’, they may still need replaced. Vacuum check them to determine if they are in fact leaking. We use a Mityvac MV8000 tool to test this.
New lines help with faster cold starts and more stable idle. Also, replacing the vacuum hose couplers will help these symptoms as well. Lines come in multiple colors by the foot.
