Wastegate issue

Postby S@MO 1 » Mon Feb 12, 2018 9:36 am

Hwzit Gents

Need some help please.

I have a Mk4 1.8 BT with ext wastegate. I have the gate hooked up to a Turbo Control valve and the valve to the boost controller.
When i switch the valve on to turn up the boost, the gate opens and stays open, therefore no boost, when i switch the car and the valve off, the gate closes. Car runs fine on low boost.

Any ideas?

Thank you

Have you tried connecting the Boost controller directly to the Wastegate and boost source?
