Je höher die Aussentemperatur desto grösser der Dieseldurst? | Posts 16+

Hello,

Wenn Du damit leben kannst nur den Schlauch abzuziehen und zu verschließen kannst Du das Loch vergessen. Sure, here is the translation of the text from German to English:

'For explanation:'

- The hose that is disconnected from the AGR valve must be sealed to prevent a drop in the overall vacuum level (for example, the turbocharger control unit also relies on vacuum).
- The pressure equalization hole is only necessary if the blocked hose is reconnected to the EGR valve (Then it's not immediately obvious). The hole is then placed between the blocked part of the hose and the EGR valve to prevent the valve from slowly drawing in air if the blockage isn't perfect, which would then close even more slowly or not at all. I don't think there's much more to say about it. Please refer to the technical article for further details.

Thank you very much for the picture and, especially, for the further explanation about the pressure equalization hole. I would certainly have designed it as a 2 mm hole.
So, I'm sure I avoided making a mistake.

Thank you again.
