E30 Zone

I have a very annoying problem. My engine is running very rich and black smoke is visible. the smoke and smell of unburnt fuel at the exhaust is so strong it is not possible to stand there more than half a minute. these are the stuff on my car... - e30 with e36m42 engine - has AC installed (e30 type...

hi; I have a very strange problem. my car jerks frequently when running because it is losing ignition (no sparks) momentarily but this jerking becomes more frequent when I continue running the engine. a few minutes later, the engine would lose ignition completely and stalls on the road. then, cranki...

I'm at a bit of a disadvantage here, because you're asking about something that has been wired by third party, not something wired by BMW, which has now gone wrong. All I can suggest,is that you check for 12 volts + on pin 85 with the aircon. switch on, falling to 0 volts with it off, and for 12 vo...

Why " of course I have"? Air con. is a rare option on a UK car - at a guess, less than 5% have it. Pin 85 of the ECU should be connected to 12 volts + by the air con. switch when you turn the air con. on., which increase the idle RPM. This should be a black/purple wire at the switch, changing to pu...

yes of course i have. in order not to make the engine die during idling, he did something. but this turned out to be error code 85

I have this constant error in my DME 1.7.2 (stock) always. i have this error code 85 in my DME constantly. I don't know what the mechanic did to my a/c. i would like to have this error removed entirely. but the mechanic is not willing to tell me how to do it nor is he willing to do this I did this i...

Service indicator fault needs to be investigated ASAP, since it's probably caused by failed batteries on the SI circuit board. Failed batteries tend to leak corrosive liquids, which will write off the electronics for the entire instrument cluster if ignored. Is there actually anything wrong with yo...

i have got this engine with its ecu and harness completely swapped into e30 in 2013. But lately, i have been having this... DME 1.7.2 errors when diagnosed: 100 Engine Control System 85 Air Con compressor The "100 Engine Control System" error is more critical. Does anyone know what this error is? Ho...

Engine vibrations up to 3000 rpm.

hi; I am running an e30 with a/c with a motor from e36m42. at the moment I am using m40 single mass flywheel. I would like to know what the original equipment for e30 m42 is? some say twin mass and some say single mass. I do not have any desire to modify. I use the car for everyday use and hence acc...

Yes. The entire thing intake DME wires AFM etc. I've contemplated changing to e30 type intake but you'll have many headaches. The DME needs to be this type too

recently a user meddled with the metering of my AFM. as a result of this, my fuel economy suffers quite badly. is there any way the diagnostics can tell if it is operating rich or lean or optimum. I don't like this experimentation. so, how can I set it back to the original setting? the AFM is one fo...

thank you speedtouch. I will check this. but as you know the vibrations exist even without load. have a look at this https://www.centerforce.com/images/sites/centerforce/pdf/DiagnosticGuide04DL.pdf look under "Pressure Plate Improperly Balanced" page 5. I am inclined to think this may be the culprit...

Brian,
I am yet to do a diagnostics. the mechanic today did not have the tool to check for me. I am asking if plug cables need to be replaced? what is the experience of users here?

Engine mounts are new. I changed these and still doesn't cure the problem. Spark plugs are new too since may. What would diagnostics show if there's a misfire? However, when cruising at say 4000 to 4500 rpm, it's smooth and quiet too. Have a look at the in car video recently I drove to Phuket Thaila...

Brian; Maybe BMW just doesn't want owners to pollute the atmosphere by disallowing hard acceleration. Anyway, the engine vibration is there even when car is stationery. Say revving slowly up to 3000rpm. But the vibrations seem to reduce or disappear when I'm cruising at 4500rpm or whatever rpm highe...

Hi guys, I just got a new resister original BMW item that plugged into the connector. It appears that the acceleration is now normal and I can do 180 easily while second gear and third pulls easily to 6500. I'm quite happy and will next check diagnostics to verify that the tank ventilation error goe...

Haha. Very strange they provide a quick fix in addition to the proper way of solving problem. Hmmmm BMW don't know what they're up to

Thanks.

Item 8 is standard BMW component that plugs into the connector?
Why does BMW make this available?

Ok. I've read what a limp mode is. Now I checked my engine bay and found the connector is left dangling. Where is the resistor installed? All I see is just one wire with a connector socket. Also how does a resistor look like?

Thanks

Oops I'm sorry I didn't realize. But pardon me for ignorant. What's the
function of this thing? From the parts diagram, it seems this is standard item on the e36.
So how would fitting this fool the ECU?

Thanks. You said absence of resister won't affect performance? But earlier you also
ECU runs in limp mode thereby affecting performance???

Thanks. I'm in Singapore. Doesn't say where I can get this resister. Is this a generic thing? Any pictures?

How do I fix this problem? You mentioned the resister. Where do I get it?

The inlet to throttle body is plugged. And the electric socket is left hanging disconnected. What is EML warning light? Can you tell me where I can get the resister? Is there any part number associated with it? Thank you for your guidance. Appreciate it very much. But would this cause problem in acc...

No. It's not connected. I don't see where this should be connected to??? The diagnostics shows this error constantly. But the mechanic says this is ok. Should I be concerned? The error is alway something like fuel tank vapor error not connected or something...

hi; I have a e36m42 1994 swapped into my e30m40b16. it didn't go very well. after installation, I immediately experienced the following: 1. engine vibrations most noticeably from 2000 to 3000 rpm, felt through the steering wheel; 2. loss of acceleration when you floor the pedal - it just doesn't wa...
