As I promised you in my previous post (BMW E36 OBC (On Board Computer) Manual - Part 1) which I published yesterday, here’s the second part of the BMW E36 OBC manual. It turned out that it’s a valuable source of information. I didn’t really expect the manual to be this precise, but you know what. It is precise. I really enjoyed the information it provided.
I hope you find this post useful. Now it’s time for you to try this information on your car, so hurry up. What are you waiting for?

The corresponding LED flashes and the display shows the stored limit briefly.The warning is repeated if the speed limit is again exceeded after the car’s speed has in the meantime dropped by at least 5 km/h.

It has been a while since I purchase my BMW E36 and since that time, I have been looking for the English manual for the car as it came with the German one. Unfortunately, I was unable to find the English version anywhere on the web. This pushed me to use Google translation tools which do not perform a good job in translating the German text into understandable English.
Today, while I’m searching the web, I have found an unclear version of the English manual which talks only about the on board computer (OBC). Only 7 pages manual. So, I took it and decided to publish its content on the blog hoping the you will find the information provided useful. Today, I’m posting part #1 of the manual and I will be posting the rest of it in the next few days. So, please stay tuned.

Hi Guys, One of the issues that were annoying me about my car is the OBC (On Board Computer) check button. Whenever I press that button, I was receiving this row of orange squares that I didn’t know what they meant. After a while, I thought this meant the car was ok and that there’s nothing wrong to report until today when I found an article that’s talking about this exact problem and how to unlock the check functionality. It turned out that the row of orange boxes (which looks like a full battery) meant that the check functionality is disabled in the car and that you have to enable it simply by following some easy steps.

If you have a BMW with OBC (On Board Computer). It’s most likely that you will face a problem in its back lights sooner or later. Luckily I didn’t face this problem with my car yet, but my brothers car has this problem and his car’s OBC looks really disgusting. The problem begins when one of the back lights of the OBC decides to die and your OBC which you love to play with from time to time starts to look like a guy with black eye. At that time, you know that you have to do something about it and I know. You will be thinking … man, I shouldn’t mess with this OBC because it looks really complicated and I may end up breaking something. Guess what? you are wrong! Fixing the OBC back lights is a very simple task and it’s the subject of today’s post. I hope you enjoy this post and find it useful for your car. By the way, I want to thank Eduardo Cesconetto the original author of this great post.
