About Limp Home (limp) mod ...

Good day friends. 2008 model type electronic gear I have 308 1.6 Vti with LPG. I had previously opened a subject about this malfunction. Here's how: When the gas level drops and the fuel light comes on, the transmission puts itself in "limp home" mode. This means that. Gear does not go above 3. You can't use manual gear. The car gets heavy like a truck. In addition, with this limp home mode, problems with knock-on operation and shaking begin. When you take gasoline and turn off the fuel light, the transmission exits the limp home mode, but if you do not turn off the fault light, flickering and knocking continues. Since the vehicle is LPG, the fault light is always on. It is not yet possible to figure out where this problem originated from. I replaced the solenoid valve, then the spark plugs and ignition coils, according to the service's recommendation. I had the LPG system completely removed. The software of the engine has been updated, and I have not received any results. As the fuel light turned on, the fault continued to appear again. I took my car to the authorized service in Antalya 3 weeks ago. After connecting it to the device, they said that the parts I wrote below should change, and they changed it after I gave approval. The vehicle was very stable. Especially I burned and used the gas light and there was no problem. But after traveling 700 km, the same fault repeated with the burning of the gas light. As if nothing has been done. When we went to the service and read the malfunction again, the following error codes were read: p 0420 Malfunction catalyst aging, 0172 richness adjustment error, 2196 inlet and output probe, affluent richness, 1336 cylinders combustion disorder, 0325 malfunction sensor signal, 0020 CAN engine torque information, 0022 CAN engine torque information either it was caused by a catalytic converter or that the engine brain was failing. Let's go now with trial and error. I don't know how much it will cost. Maybe a drop of information will help me solve one of your problems. Thanks in advance ... 3 seconds2012-04-01 11:36:54

If the service changed oxygen probes by looking at these errors, wow. As many masters have made and understood, the errors shown here do not indicate that those parts are defective, but they lead to the error. By looking at these errors, if I make a comment, I will rob. There was a burning disorder in the cylinders for some reason. As a result, unburned fuel mixture went to the exhaust manifold. This mixture was given to the exit since it could not be converted in the catalyst and the output produced a different value to the oxygen sensor. The brain gave the catalyst error and the oxygen sensor error when this value was seen. In my opinion, your vehicle has nothing to do with catalysts or oxygen sensors. There is some kind of burning disorder in your vehicle. The reason for this needs to be investigated.

On the screen where these error codes are displayed, there is information such as at what time and second, at what speed the error occurred. I would like to ask a question. This problem also occurred when LPG was in your vehicle. The needle, which shows the level of gasoline as you know, constantly drops regardless of whether LPG is available or not. Was this a mistake when the gas light was on while you were on the road with LPG?

This problem started with LPG installed on the vehicle. As you said, even if the vehicle runs on autogas, the fuel needle drops. And this problem arises when the petrol light is on while you are on the LPG or gasoline. Could the burning disorder you mentioned above be caused by the motor brain? It may not be able to adjust the fuel mixture. According to the last comment of the service, & nbsp; either the converter is faulty or the engine computer.

This is an electronic problem, as there is the same error in LPG and gasoline. I do not think it is due to catalyst. For now, I can't think of anything but I will investigate.

Thanks ...

I recommend you to have a software update

The engine software has been updated, but the change & nbsp; It happened. What other updates can be made?

p 0020 CAN engine torque information
p 0022 CAN engine torque information

I know 100% of the source of these two messages. >

No sister solenoids have not changed. Oxygen probes that change. Does solenoid failure protect automatic transmission?

already sendolid failure protects the engine .. either the brain or sendolid changes in the pressure sensor while the sendolid changes. One of the 2 faults is definitely the general problem of 307 users.

What is the last situation do you still need help

I will be as if I was hooking the subject, but I'm sorry to see my 4 months ago & nbsp; 2008 model tiptronic gear LPG 308 1.6 Vti I have the same problem in my vehicle, I am waiting for help again because it does not share information about whether it solves friends and maybe there is someone to help.

[QUOTE = 3seconds] [QUOTE = okan4037] already sendolid malfunction protects the engine .. either brain or sendolid varies in the pressure sensor when sendolid is changing. never gave "Automatic Gear Fault" error. It gives "Antipollution Fault" error & nbsp; and then goes into protection when the fuel light turns on. When the fuel light goes out, it leaves the protection. Despite this, can we say that it is caused by solenoids?

ARKADAŞLAR,

Search me `` Antipollution I was getting the `` Fault '' error. But I need to put some good fuel and force a little bit of the car. After the dirty fuel was thrown in the car, the engine error goes out automatically. The error disappeared by me twice 2 times. It may be caused by lpg.

is there anybody who solved the problem?

There may be dirt at the bottom of the tank, this dirt may be blocking gasoline injectors, the tank will be brewed, gasoline injector cleaner additive, put into half tank and the vehicle can be slightly compressed, maybe it will be a solution, cheap method

Sir problem was solved, the rear oxygen sensor is defective kablosal interruption comes and goes bank 1 sensor 2 voltage 0 shows, did the problem with the OBD device abroad in siparişini part detect and myself .. (20 USD rear sensor) $ 400 :-D Sensor 2 of office in Turkey This is the reason why adjusting the amount of fuel entering the engine protects it when the fuel light comes on.

Of course, first I disassembled the sensor and did not clean it, I connected the on board dianostik device and found that the os2 did not fluctuate, then fixed it when I played with the bottom dip cables and fixed it, I fixed it, but the vehicle vibrates as it goes and goes ...
