E350 coupe in limp mode

[A16XCH]

Hi go easy on me please as this is my first post.
I have a 2010 e350 coupe and love it however it’s just gone to limp mode and won’t go over 3000rpm. My friend read the codes and it’s said the temperature sensor upstream of turbo was reading -247°c.
I bought a non refundable replacement sensor but this has made no change.
We did get another code though p11da00 undocumented code. Any ideas anyone please?

Been to a Mercedes independent garage today. It’s the differential pressure sensor.

Readings like that, either minus or plus "infinity" normally means either short or open connection.
Try to find the exact location of that sensor. Disconnect and if the sensor is a thermistor, measure
the resistance. It should not be zero or open. If there is a readble resistance (in the order of kiloOhms)
the connection is the probable cause. Investigate the contact elements if they are not properly seated
in the housing or if a crimped connection has been exposed to water ingress causing corrosion.

Thank you for taking the time to reply. Car collected today and is back to normal. Very pleased, all for the grand sum of £105. Highly recommend Hampshire service centre,Mercedes specialists. Very quickly dealt with and friendly too!
