500E Fault Codes
 

Hi Everyone,
I have eliminated most of the diagnostic module codes on the 500E exept for:
5-Exhaust gas recirculation inoperative
and
19-Fuel injectors open/short or self-adaptation in LH-SFI control module (N3/1) at limit

The number 5 code is intermittant but the 19 code will come back hours after it's reset. Anyone have an idea of what's causing this?
Thanks,
Adam

Oh yeah, one more thing. On a cold start, the engine idles very poor for about 2 seconds after the cold start fuel enrichment state and then runs fine. It does not seem to be a big problem but, I figure it's worth mentioning just in case that has something to do with my problem.
Thanks,
Adam

The EGR problem is either vacuum loss or plugged metal line from below the valve to the manifold.

For code 19 you need someone with a MB scanner that can read LIVE data from the LH-SFI computer. They need to look at long-term adaptations to see if the computer is at the control limit OR if there is a injector/wiring problem.

Adam . . . yes, the dreaded DTC#19. . . .
 

rears its ugly head again! One thing is sure, if you have a '92 - '95 MB, you will as some time experience this problem. But there's an affordable solution.

I've sent you email.

Jim: can you email me that solution as well.

Thanks,
Neil

I just sent . . . .
 

you an email via MSF since I probably don't have your new Florida email . . . . . .

Jim: my email hasn't changed.
