Unhappy Weird 30FF boost leak fault - 11-14-2021, 03:15 PM

Hi all

I need help to solve my weird "boost leak".

Symptomes:
- pulsating boost
- 30ff, mostly in 3rd and full throttle
- spontaneously also the following errors: 2ABC, 3100

Following things i have already replaced or tested:
- replaced all vacuum lines
- testet vacuum canisters
- testet westgate actuators, no vacuum loss. The rear westgate is working fine optically. I don't see the front westgate, but it sounds good when i test with the vacuum pistole
- replaced vacuum solenoids with working ones from a friends car
- replaced fmic with wagner evo 1
- check CP and other cold side hoses
- Change JB4 firmware from the 32.15 to 32.16 for testing
- i have no westgate rattle

But unfortunately no changes.
After I received the 2ABC error, I thought the MAP sensor is faulty. but then the error should always be displayed? Btw. I use the stock (2,5 psi?) sensor.
The car is im stock stat until the fmic and jb4. Turbos have 60'000 km.

I have installed a JB4 G5 but since i have no boost i used it in Map 4.

made a small log. I hope it will help.

Thank you for your help. (And sorry for my bad English)

Boost leak test it. Make sure in menu 4 that setting 3 is selected also.

Sorry, i understand it. You mean the tachometer. I use the App. Biut i checked the menu 4, it's already set to 3.

So now i have good news, i made a DME update and the boost are almost back )
sometimes i have the feeling i still have a boost leak. there was also a 30ff error in 6th gear with full throttle at ca. 3000 rpm.

I made a new log, are you think is still a boost leak?

Thanks

Doesn't appear there is a boost leak. Make sure to turn on 6 cyl timing also.

Looks pretty normal for map 0, try a log on map 5 and lets see how that looks.

For 30FF errors see this...
