[Engine] Engine judder at 1800 rpm

[rodthemod]

Hi

Berlingo 2013 1.6 hdi about 120000 miles
My engine "judders" at about 1800 rpm, great up until then and great after

I've read it may be an egr issue?

Any one got any suggestions?

Not directly helpful,but that's occurring at nearly maximum torque rpm which suggests its turbo/exhaust management related.
Have you got fault codes to research?

[rodthemod]

No codes coming up
Just engine fluctuations

[evdama]

Is that with an obd?

[rodthemod]

Yes just a cheap reader

You will only be able to progress further with a better diagnostic tool.

You need accurate fault data.

You need accurate live data.

You can only guess otherwise.
