Quiz, Codes and their solutions....Limp home mode when car warms up is the problem
I got the following codes on the CIS-E
code 7 ?
code 18-current to idle air control valve
code 29-difference in ECT between CIS-E control Module and EZL ignitioncontrol Module

MAS codes
13-Excessive AC belt
14 Vehicle speed signal/circuit
15- short cirvuit detected in fuel pump circuit

DI codes-with car not running
17-crankshaft poistion open or short cirvuit

Can anyone help with solutions to these codes...this grey market 1990 500sl with early ASR is killing me.

Thanks,
James

First step should be to clear the codes, drive it some more, and see what comes back. The code 13 is actually "excessive AC compressor clutch slippage" - ancillary problem. Perhaps a bad ignition control module - not uncommon at least on U.S. cars.

I agree w/clear and drive to see what first comes up,

but..seeing what you have now..
I would check the ohms value across the CIS/EZL thermistor and see if they are in fact, not the same. If not , that is a problem.
I would also check for equal tire size/PRI for VSS code ..that will trigger ASR.
Post what you find after clearing and doing those quick checks..

Also check the belt tensioner, a failure prone item . . . . . pull on the belt and see if it has excessive play
