Engine light on, car in limp mode

[Lucky27]

Hello everybody, I recently bought a Mercedes E220 Coupe 2014. A month ago the check engine light came on and the car wouldn’t go over 3000 rpm. Sent it to the mechanic, cleaned dhe particular filter & changed EGR sensor.

It was all OK until yesterday, same thing repeated again…

Any suggestions??

Boost leak (intake manifold or boost hoses)
Bad injectors
Bad diffrential pressure sensor

In that order

All a guess without the codes though .

Have codes read. Post back here. Too much guesswork otherwise.
If Yr intent is to keep car, brand go get yrself icarsoft mb v 2 or. Better and become familiar with it.. Frankly the car should come with it!!
