P0299 - Turbocharger Underboost Condition | Posts 48+

Hi everyone, I'm back.

Okay, so I completely replaced the right intake manifold module, along with the connecting rod. There was a lot of play, but I reused the same actuator motor.
As far as I can tell, everything is working fine.

The left shoe is almost new, it was changed about a year ago, and it has barely been used.

"Yesterday, I tested the car again, but unfortunately, there's still a loss of power. However, once, in 3rd gear, there was no loss of power, unlike the last time two weeks ago."

1st, 4th, 5th, and 6th gears are all good. 2nd gear is okay. The 3rd gear consistently experiences a loss of power at higher RPMs (3000-4000).

Why only in the hallways? Transmission problem?

Either electrical sensors, etc., or turbochargers from BR-TURBO are useless, or something related to fuel supply.

If it doesn't occur with the original software, the modification is useless.

Okay, here's the translation:

"Also, if I'm doing an actuator test, also known as a "live data" test, on the engine control unit (ECU), for example, in a cold start situation..." Control motor for VTG J724 (78.91% at 3.5V, 19.53% at 1.34V) consistently displays an error after 1 minute and then stops automatically, as shown in the photo. This also occurs during throttle or glow plug tests.

That doesn't happen with a transmission control unit.

Sometimes, when plugging in the OBD adapter, there is no power or connection. It may only establish a connection after repeated plugging and unplugging, and the contact at the OBD port seems to be loose.

-> The manufacturer of your OBD device is asking what's going on with it.

Ross-Tech (VCDS) and CGSULIT support is available here. The manufacturer knows the specifications of your system, not me.
I've seen contact pins in OBD sockets that have shifted backwards, which then caused poor connections.

However, this has nothing to do with your problems with the engine control unit (ECU) software, and I can only repeat myself: if the car functions correctly with the original software, then the problem is the modified software.

I have written this several times now, and I will not repeat it again.

Best regards, Rainer.
