Leak in Air Intake System P2279 00 (167) 2.0 TDI RS CUPA

Featured Replies

Hi,
When accelerating, the car enters limp mode, loses power and the glow plug icon lights up, I am posting errors and logs at the bottom. I have already replaced the vacuum lines and the N75 valve. What else to check? I also checked the bulb with a syringe and it holds pressure.IMG-20231111-WA0003.thumb.jpg.7dc05c308c84b8fe4e61dd6abc5ed824.jpgIMG-20231111-WA0004.thumb.jpg.e8b6f2eb3febafcbc7b295cd4c476a21.jpgIMG-20231111-WA0006.thumb.jpg.8c27dcf6e43b019d55bbf259a36bfc62.jpg

The location of the turbine bulb is 3699.6mA in the lower one and 694mA in the upper one:

I checked this cable by eye and it is good, I also tightened the clamps:

And I replaced these hoses + valve 6 with a new one

Please help, what else could be going on 😕

A check by eye won’t be enough.

 

a smoke test of the car is required to find pin holes, poor connections, one way valve failed, pcv fault, EGR leaks

I also checked the one-way valve. The leak may only be the pipe I marked?

boost pressure sensor, best regards.
