E36 M3 error code

[Coupe Turbo GP]

Howzit guys,

I took my car for diagnositcs today and picked up the following code: 155 Control module fault, fault memory master.

Can someone please advise me what to check or replace?

The car feels very down on power.

Thanks :thumbs:

As a first I would think it is a power related issue so would instinctively look at DME relay.

Either spray some Q20 on the contacts or replace.

First step

Go for a proper diagnostic.

What control module, one would assume DME ?

You need to diagnose using DIS, INPA or ISIS...

Yes it is DME
