Re: Replacing my RCM/air injection issues

From my research here, it seems that this is a common issue and there is a chance that my relay control module is bad or has poor connections. Rather than resoldering etc, I think my best bet would be to just purchase a new module and replace it. I am a cisco guy, not a car guy so be easy on me. I am having trouble finding the part number I need for the RCM. A1705450305 is what I think it is. If someone could clarify this for me (or check out this listing for me real quick:
Mercedes W210 E320 1999 SLK230 Engine Control Computer Module Overload Relay K40 | eBay ) it would be greatly appreciated.

These are the numbers.
MB #170 545 03 05
Mopar #5099007AA
That one you have listed may, I repeat may work, a member did use another one and it worked.
The RCM can be fixed, either re-solder if the car stalls suddenly when hot and the starts when it gets cooler or replace the $5 relay for the air pump problems.
