AGR EGT Sensor for Audi A6 2.5 TDI

Hi there,

'On my A6 (2001) 2.5 TDI with engine code AKE, there are three rectangular holes (approximately 5mm wide) drilled into the side of the vacuum actuator for the EGR valve. I'm finding soot everywhere around these holes. Is this normal, or should I take a closer look at the actuator?'

Greetings / Larry

The holes must have been viewing ports so that you could see the plunger moving from the inside (e.g., during a self-test).

In my opinion, the result shouldn't be Russian.

That means there's a leak somewhere that shouldn't be there. It's difficult to determine how serious the problem is based on remote diagnosis alone.

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.
