1992 W140 119 engine, S500 in limb home mode. You must have heard of this problem a number of times now. I search the forum and still cannot solve my problem. I posted it in other forum and.... not much reply. This forum is rather active and i truely believe you guys can solve it to help me and others.
Question is what is the problem and what have i done so far?

Here it is.

Car was in Limp Home Mode. Check engine wiring harness found out the insulation of wiring harness to the throttle actuator and to the injector were gone. Replace wiring harness to the injector and re-wiring the throttle wiring harness. Put all back together the car run realy smooth. After using it for a month or so... the engine started real rough and into LHM. The RPM jumping up and down. Also black smoke coming out from the exhaust. Spray the Air Mass Sensor... no difference.
Check the rest of the wire - all ok.
Check all vacuum line - they are all ok and intake.
Replace fuel pressure regulator - no difference.

Use a Trisco Palm Scanner (PS-411-BENZ) to read code and these are the results.
LH, HFM, ME(R)
Read DTC - system normal
Read store DTC, two codes appear. 05 and 10.
Code 05 says Intake air temp sensor shorted or open CKT.
Code 10 says O2S 1 signal, shorted or open circuit.

LH,ME(left) - No ECU control or no data.

ETC system - No data from vehicle

DM system - No data from vehicle

EDS system
two code, 10 and 13
Code 10 says No description.
Code 13 says Elec. Diesel sys. ctrl unit faulty (internal fault memory)

BM system - system normal

DI system - system normal

EA/CC/ISC
Code 224 says Idle speed contact switch S29/3 fault

EZL system - system normal

OP system - system normal

PML system
Code 03 says (1) LR wheel speed signal error. (2) LF wheel speed sensor and circuit fault (W129/W140 since 94)
Code 04 says (1) RR wheel speed signal error. (2) RF wheel speed sensor and CKT fault (W129/W140 since 94)

ABS/ETS/ESP - system normal

BAS system - no ECU control or no data.

ADS system - data error

ASD system - data error

SPS system
Code 11 says Volts supply at speed sensitive power steering Ctrl module faulty.
Code 17 says no description

SRS system
Code 139 says no description
Code 03 says low volts, voltage supply circuit 15R

ICM system - no ECU control or no data

RST system - system normal

RB system - data error!

IRCL system - communication interrupted

PSE system - system normal

ATA system
Code 15 says IO SIG not received from interior motion sensor or button on interior motion sensor transmitter and receiver unit pressed at least once or infrared interior motion sensor control unit (N26/3) not present or defective

CF system - system normal

AC system - system normal

OCP system - No ECU control or no data
LCP system - No ECU control or no data
PTS system - No ECU control or no data
EIS system - No ECU control or no data
D2B system - No ECU control or no data

Try to delete the codes, however the following codes cannot be erased.

EA/CC/ISC
Code 224 says Idle speed contact switch S29/3 fault

SRS system
Code 139 says no description
Code 03 says low volts, voltage supply circuit 15R

Also a number of codes keep coming back. Very irregular.

====================================
Now what is next??
Found out the insulation (biodegradable I suppose) of the wire connecting to the alternator is gone. The wire is connected to starter, battery and maybe circuit 15R. I have re-wire the wire and a lot of codes are now gone.

EXCEPT
EA/CC/ISC
Code 96, 117 and 224
Code 96 says Starter lock-out and reversing lamp SW S16/3 fault (new code appear)
Code 117 - no description given.
Code 224 says Idle speed contact switch S29/3 fault

SRS system
Code 03, and 139
Code 139 no description given
Code 03 says low volts, voltage supply circuit 15R

What is my next step?
Change Starter lock-out and reversing lamp SW S16/3
Change Idle speed contact switch S29/3
Check all wires around engine compartment - all good
Check all wires inside the car - all good
Check connector related to circuit 15R - all good

Read code and Code 96,117, 224, 03, 139 STILL THERE AAAHHHHH

I got no more ideas mate.

NEXT is........ USE A HAMMERRRRRRRR

benz-tech

how could post #1 and post #7 even possibly be from the same person??

everlyne

Yup... same person. I did it all by myself.

Answer is air mass meter or air flow meter.

Thanks guys.
