Mercedes S600 W140 ( Problem ASR )

[Maitrebruce]

Hello,

So I have a Mercedes S600 W140 coupe from 1995, which has been stationary for a while because of a rather painful problem, therefore ASR problem, after several diagnostics I decide to replace the two butterfly boxes (Driver and Passenger), I now have new fault codes and still the ASR light, (no acceleration ......)

The fault codes are as follows:

002 : Coolant temperature sensor 2 B11/10

003 : Coolant temperature sensor 1 B11/10

004 : Air mass sensor with hot wire B2/4 Volt too large / small

016 : EGR switchover valve Y27/2

022 : Oxygen sensor heater G3/4

024 : Oxygen sensor heater G3/4

028 : LH resistance trimming plus R17 / 3

What do you think ? Thank you for your opinions

Regards

The fault codes themselves, as you have posted, are they not
indicative of your problems.

Welcome to the forum.

hello thank you for the welcome

After error reset there are only two errors left:

016: EGR switchover valve Y27 / 2

028: LH resistance trimming plus R17 / 3

The question is, can the EGR part affect the ASR? And what can resistance triming correspond to?

What do you think ?
Thank you
