Hi Theo,

We assume these are E213 (launched in 2016) E-Class models, which would mean they’re the E 200 d and the E 220 d. And there’s precious little difference between them, as they both use the same 2.0-litre, four-cylinder turbodiesel engine. Basically, the ECU is altered on the E 200 d to deliver lower outputs of 150hp/360Nm, compared to the E 220 d’s 194hp/400Nm, in order to try and deliver better economy/emissions.
