Hi guys, My standard series 7 has all of a sudden lost all its boost im guessing the wastegate has seized open or something?an ideas.has a boost gauge and was running the 10 - 8 - 10 psi before it gave out.turned car off and when i re drove tens min later it was like this? is running an apexi bov , checked and that working fine.thanks heaps

 

Have you checked the WG?
Are you running stock turbos?

 

One of your intakes hoses probably popped off. Double check the connections and look for cracks in the plastic pieces as well.

 

In the 3rd gen FAQ stickied in this forum, scroll down to the T section and start reading the links for Turbo Troubleshooting.

Its normally not the wastegate. Usually a boost leak from a coupler, one or more of the vacuum hoses popped off, or an issue with a solenoid or a check valve.

 

Thanks guys, will look into it

 

My FD RX7 has the same issue. The gaskets are blown out, I am currently fixing this. this also may cause you to loose boost. Its worth checking. Usually you can hear it though.

-cheers

 

that it is standard with no modifications...

thankyou all was a hose leak.just didnt look hard enough the first time
