AGR Valve: Causes, Symptoms & Cleaning

Hello,

A few days ago, I disassembled a PD cylinder head and was quite surprised when I saw the EGR valve. Consequently, the intake manifold was also heavily clogged.
Unfortunately, I don't know the mileage, but based on the condition of the cylinder head, it probably wasn't extremely high.

That's all I have to say about the topic of agricultural land and sludge.

Greetings.
Thomas.

Hi Thomas,

Do you also have any photos showing what it looks like on the intake side?

The AGR shut-off valve unit is screwed onto the intake manifold.

I'm interested in a photo of the Kruemmer.

Okay, here's the translation:

Thank you.

Hi,

The ARL has an AGR cooler, which naturally looks the same.
My digital camera is currently being repaired, but I will take the pictures later!

Greetings.
Thomas.
