Please help me, w210 ETS issue

[John123568]

Hello there.

I have an abs/ets fault on my w210 e300 diesel 1996, it’s only done 76000 miles

I have had all the reluctor rings and abs sensors replaced.

I have had a second hand abs pump fitted

I have had a Brand new K40 relay fitted which controls a variety of things including the ets system

Since all of this workI have had it plugged in and it has come up with the fault code: 024. High pressure/return oil A7/3m1, relay A7/3k2
Can someone advise as to what is the problem or I am going to scrap my car

Thanks in advance
John
