Hello guys, and welcome to MetSpimla. Today's video is a short video explaining about a certain malfunction that many of you have had. So I decided to make a video for you. Many of you have had the drive train malfunction light, and after that there's UG loads messages saying, reduce power, etc. If you get that message, don't panic, but not straight away anyway. So what situation usually puts the air light on on your car? That malfunction light usually comes on when the engine is under load. For example, when you're pulling the way, when you're overtaking or driving up a steep hill, even normal driving conditions can put this light on. And also when it is cold. So what happens is the car's computer can detect there's a fault so to protect the engine and gearbox and you, the car goes into safety mode or lim mode. And this allows you to get home safely without damaging the car or the engine. So what kind of symptoms can appear when this message appears? Well one thing is that the car will start running rough and the car will start shaking. Sometimes when you're idling, if you're put it in drive, the car might just cut out. Sometimes it can cut out when idling anyway. I've seen that some cars with this error can also put out extra smoke at the exhaust, which is not good. Another tattoo sign is when your car is in lim mode, your car will not change gear. For example, if I go up or down the gear and drive in the long, it's a spacey stuck in one gear. But you can put the car in park and reverse. And another one is that the car may not start at all. So apart from them symptoms, there may be some more. If you can think of any other symptoms, please comment down below it because it's nice to help each other as a community, as we're all still learning. So what should you do if this happens to you? It happened to me a few years ago. I was driving in Moscow and about 60 miles an hour when this message popped up. I penn it for a second because I've never seen this message on my car before. So I pulled off a few kilometres on the road and the safe location, which was in petrol station. I shut the car off and I started it up. But what I should have done really was turn the emission off and wait for about five minutes. This allows the car to sort its head out. So basically, by me turning the car off and on, kind of reset the error. It's still there, but a car allowed me to get home safe and at a normal speed with no issues at all. The error didn't come back for a few more days. So I did this a few times and to be honest, I should have investigated it straight away. So what I should have done was check the oil level of the car and also keep an eye on the car's engine's temperature. For example, the oil temperature. To do this, I did make a video a few years back about the secret menu. So if you want to see how to get a new car's secret menu to temperatures, please find that video. So another thing you should do really is to go and get the car scanned. Or if you have a scanner, do it yourself because there's obviously a reason that the error popped up. And the car should have saved it in the system, even if you turn the car off and on. So if you have a scanner, try and scan the codes from the engines DME and the gearboxes EGS. So what are the common problems which can put this light on? So if the car's misfiring, there's a chance that it's the spark plugs or the call packs. If you want to know how to dye those a call pack or ignition coil, I can make a video for you. Just let me know down below. With some cars, there could be an issue with the high pressure fuel pump. If the pump isn't given enough fuel, the coil cut out and obviously struggled to run. This usually happens if you're pulling away quick overtaking or basically requiring more fuel from your engine. Some cars with higher miles can get a clogged kettle converter. Basically it restricts the gases leaving the exhaust and that can cause issues which puts on that light. My issue with my car was I let the fuel get a little bit too low, which is not ideal. Never let your fuel get too low on your BMW or any car. When the fuel gets too low, you're basically increasing the chance that you're going to get dirt into your engine and fuel system and all that, which clogs it all up. Apart from me, letting my fuel get too low, the petrol in Russia isn't as good as in the UK. That's why I need to use the best fuel as possible in Russia. Luckily for me, this thought only happened about four times. Luckily for me, this error only happened about two or three times. After that, the car was perfect and never had this light appear again. But I did use my scanner to see what the fault was. It did tell me that there was problems with the fuel I was using. As you may know, with the M13, the injectors can be an issue if you don't drive the car hard, like me. So that's why I had to inject a problem a few years back. Not because of the low fuel, but because I just put it around everywhere. I don't drive fast. So it's also worth checking your fuel injectors if this ever pops up. But remember, scan the car first. If this error though happens usually in the cold weather, it can be due to the battery mess in the bell. Or you might have something in your 12-volt socket, second the life out of the system. So it might be worth checking your wires on your phone charger too. Some people may get the error light appear after they've got the car serviced. For example, some of them have left a connector unplugged, or they may have dropped oil on the engine and it's got into the electrics and messed up that way. So there are so many things which can cause this issue. So please get your car scanned to save yourself money. So here's a basic list, not the long-toddly version of what can cause this issue. I'm going to read up the screen now because my brain is a bit fuzzled. So I will start close and cause it. 40 callbacks. The catalytic converter can be clocked. The high pressure fuel pump, not sending enough fuel through the system. As well as dirty fuel and low quality fuel can cause this issue too. 40 fuel injectors, turbo injectors, turbo issues, mass airflow issues and some people say even they have guessed it. So it can vary so much. So I'm trying to watch this video now because as I said before my battery doesn't last on the tool even though I've used two batteries. If you can think of anything else which would be useful for this video, please comment down below because it's very useful we share our information with each other to help each other learn. Anyway thank you so much and take care. Goodbye.
