Access to BMW320 1992 model fault codes

[Wilken]

New guy on the forum!! I am the proud owner of a E36 model 1992 320I with merely 130000km on the clock - brand new! From Internet searches I understand that pre-1995 BMW's has On Board Diagnostics Rev 1 (OBD1). Everybody says one can access fault codes by the "5 steps on the accelerator" process. Is this also applicable to SA BMW's? I cannot get it to work - maybe ID10T factor from my side?

Need to access fault codes 'cause car developed a nasty habit of hesitating and backfiring when accelerating from idling under load. This disappears above 1500rpm. Car is normal above this engine speed.

Short answer: No

Long Answer: Only the post '95 models will blink the fault codes for you, from my reading. You will need a proper OBD1 Cable and GT1/INPA/Icantrememberthepropername Software to properly read codes from the ECU

Coming back to the hesitation and backfiring problem.

Did the following:

1. A BMW dealership "diagnosed " this as idle control valve faulty and replaced it at a magnificent cost. No change. I won't say which dealership...
2. Two coil packs were "diagnosed" as faulty - replaced. No improvement.
3. I checked the crank position sensor. Tested OK but the pigtail wire insulation was extremely brittle so I replaced that - no improvement.
4. Checked (as far as possible) all inlet manifold pipes etc for leaks, or unconnected pipes - couldn't find any.
5. Note NO oil consumption or oil smoke, and car pulls normally on open road above 2000 rpm.

Car can be driven. Symptoms are now clearer - engine hesitates and backfire through inlet manifold when going wide open throttle below 1500-1600rpm under load.

I am looking for somebody that KNOWS how the engine is controlled; which sensors are used and what the DME does. Only then can I start troubleshooting.

Any help out there?? The car is in such a good condition I just want to fix it and drive it.
