Hello, My name is Barry. Just joined, purchased a 1998 Ml320 a year ago. It has 68k and the more I drive it the more I like it. I purchased it in Az. I put about 1k on it before taking it home to Minnesota.
So here it is, I found a problem starting in the cold…. Below 20 degrees. Starts and dies, just like using valet key. Found if I warm Aam module starts good. Had a scan run on it leading to immobolizer. As I write this I have to apologize the code was??? 1570
Now, this is my secondary vehicle and I would like to delete the immobilizer.
Thinking Aam can still be a problem down the road.
Any feedback would be mostly appreciated.

98 Ml 320

Why don't you heat up the Transponder coil and/or the control module?

I failed to mention that.
I did warm the transponder ring first.

When warming trans ring, still wouldn’t start.
Code stored in engine ecm.
Which controls immobilizer for transfer ring.

Did that code # have a P before it?

Are you using a code reader or a scanner?

Please update your profile to include the year, model (is it GAS, CDI or Blue) and where you live.

That P1570 code is not a valid one which indicates that you have a code reader and not a scanner.

Look through the PDF codes and you will see that the code is non existent.
