W204 62 plate, problem with Abs,esp, tyre pressure sensor, cruise control, eco noperative after engine change!

[Remon]

Hi all, I had to do an engine change on my w204 c220 62 plate the facelift one, cut the story short, after the engine change the car is running fine but eps,abs,eco and cruise control not working.
I checked it with icarsoft v2.0 and changed both abs sensors on the front and deleted the error messages but the faults still there!
Any suggestions?

Check your batteries, you should ideally be reading around <12.6v engine off and <14.8v with the engine running, less than optimum conditioned batteries and supply voltages are a common source for multiple component error codes in a Mercedes.

ETA, As it has been an engine change, make sure you use test points at various locations around the engine compartment and not just the battery terminals to confirm continuity of what's been reassembled!

Update: today fited another battery changed the wheel hub on the front where the fault is, changed the brake switch, deleted all the codes, took the car for a drive but straight away the skidding light starts to flash, went in a limp mode no power, car is manual so it is just juddering alot on 1st and 2nd gear, then the abs, edb and esp light came back on and the car drove normal after that with the lights on.
But still no cruise control, no eco, No hill assistance and the faults still there, just don't know what to do next?

Probably best to get it booked in to a Mercedes specialist
Are you sure it’s not a abs/wheel sensor
I’ve had 2 go on mine with all the same symptoms as you
I had one fitted last week

Have a look at the brake light bulbs , I have had esp/abs /no cruise on a car before...... changed brake switch and no difference..... eventually it occurred to me it only did it when driving lights were on.... turned out one filament of a two filament bulb had come adrift and lay across the filament below it ... car in question had no bulb out warning system.

Changed both Abs sensors with new genuine ones! I will try to book it soon, thought my icarsoft v2.0 would find the fault, it is pointing me to the abs direction but that is it.

When my sensor broke last year it surged back and broke the electrics in the abs pump
Had to get a second hand one off ebay and take the electrics off and fit to my abs pump
I then had to get it coded to the car
