Radau toki straipsneli, tik man niekaip nepavyko ant savo E30:

Did you know that your BMW 3 Series has an internal diagnostic program built into the computer? Not many people know about this. On the BMW 3 Series, there is a way that you can diagnose common engine problems without having to purchase a code tool or take it to the dealer to have it scanned. This is one of those neat little features of the Service Indicator Computer; the series of lights directly under the tachometer and speedometer that remind you to change the oil and perform service. In this tech article, I will provide you with the procedure for checking the fault codes and what the codes mean. This guide will help you to diagnose any possible problems with your car.

This article is written for both the BMW E30 and E36 3 Series cars (up to 95) and should work on both models where a Service Indicator Computer is used. I will go over the small differences between the early and late cars, as they differ slightly. Keep in mind that this procedure will not work on early cars with Motronic 1.1.

Now on the E30 models, get in the car and put the key in the ignition and turn it to the second turn or “ON” position, but do not start the car. Now, press the accelerator pedal all the way to the floor, then let it release all the way back. Now repeat the depress/release cycle 4 more times fairly quickly, but not too fast. It may take some time to get this timing down correct. It should only take you a few seconds to do this. What this does is activate the wide-open throttle switch and the idle switch 5 times. This then sends a signal to the Motronic ECU to send fault codes to the Service Indicator Light.

On the E36 models, the procedure works the same way, but the timing at which you press/release the gas pedal is faster than on the E30. Just keep at it, and you will eventually get the correct speed.

Watch the “Check Engine” light. It should blink once, and then start blinking a series of four numbers. For instance, say this is a sequence you see… the light blinks once, then twice, then four times and lastly four times. If you read it correctly this means that the SI light is reading out the code 1244 (faulty camshaft sensor) The codes appear as a series of flashes for each digit. The flashes indicating one digit are about one second apart, the next digit will appear after a couple seconds interval. If there are no faults in the car, the computer will flash out the number 1444.

Here is the list of codes and what they indicate.

Na jai kas i lietuviu kalba isverstu ir as babandyciau

idomu... reiks pameginti bet kazkaip abejoju ar suveiks

Cia kiek zinau, tik ant amerikiniu veikia

teko panasu straiipsni skaityt ir e34-tam, veiksmai tokie patys, bet man tas dalykas nesigavo (ant E34 M60B30 )

Sita "baika" veikia tik su naujesniu kompu nei Motronic 1.1;

Pastatai rakteli i degimo padeti, bet neuzvedineji masinos. Letai spaudi akseleratoriaus pedala iki pat dugno ir atleidi, tada dar 4 kartus tik greiciau suspaudai iki dugno ir atleidi (isviso 5kartus, reikia pagauti intervalus). Tada viena karta sumirkcioje "check" skydelyje ir pradeda rodyti kodus tos zalios lemputes

http://www.aet-tendahl.de/motorsteuerge ... te-bmw.php

buvau ir as nuejes paminkyt pedalo, bet nesigavo nieks, sakau gal cia signalizacija kalta gali but, nes as kai degima ijungiu tai uz keliu sek. uzsirakina durys ir sakau gal sumaiso visa reikala

pas mane irgi neveikia, arba ne tuo intervalu pedala minkom... o signalke neturetu itakos daryti, nes kompas gi signalkes neitakoja (nebent kokia gamykline). beje, neuzdaryk duru ir neuzsirakins cia greiciau neskirta musu auto tokie "navarotai".

na gal, bet toj nuorodoj kur daviau raso, kad bent pas mane stovi motronicas 1.7, nebent nera to DME, check funkcijos..

pagal tavo nuoroda pas mane "320i 2 litre (6 cyl) 92-95 Bosch Motronic 3.1" tik pas mane siemens sistema... ar motronikas gali buti bosch? nors nelogiska butu...
cia kazkas tiksliau galetu pasakyti, jei kam pavyks toks patikrinimas... idomu pedala kaip ten minkyt reikia... gal per letai viskas daroma, arba per greitai, o gal isvis nera musu masinose tokio daigto

Pas mane Motronic 1.3 ir Check Control yra, tik OBC nera. Dar bandysiu pirma paspaudima labai leitai uzlaikydamas paspaudineti.

P.S. Check Control - tai kur virs veidrodelio rodo info jei perdega lempute, truskta skysciu..?

Stai ka dar radau:

Fault codes for euro-e30

My euro 325i '90 has no check engine light. Because I knew that the Motronic would produce fault codes anyway , and did some research. It appears that the codes are output to pin 15 of the computer, but the wire stops at pin 12 of the big connector in the engine compartment next to the fuse-box.

By using a little 12V light connected to pin 12 of this connector and +12 V, the codes appear after pushing the gaspedal 5 times (contact on).

Works great! Let me have your experiences.

Tankai, idomu, idomu.. tai kaip ir reiktu lempute i salona atsivest..

Nebutinai, juk kiekviena diena netestuoji ar meta kompas klaidas ar ne. Tik isbandyti reiketu ir parasyti cia ar veikia.

Nes kaip suprantu primas post'as kur parasiau tai skirtas USA, o EURO versijom tai reike lempotes viena kontakta prie 15-kto kontakto ir akumo + teigiamo poliaus.

tai ir sakau kad idomu
bet lempute vistiek reiktu atsivest, nes gaza maigysi tai salone sededamas, siaip pas mane yra CHECK skydeli, bet nepavyko sumaigyt..
