406 hdi engine fault lamp - 406

Hello friends.

I had my 406 hdi vehicle I wanted to have for a long time two weeks ago.
But for two weeks, a problem has been boring.
The vehicle was a friend of mine I knew and swapped the gallery three months later, I bought the vehicle from the gallery.

The problem with my car is this; While driving at a speed of 90-100 km, the vehicle lights the engine fault lamp and the vehicle does not exceed 3000 cycles, it protects itself. When I stop and restart the vehicle, it returns to normal, but the engine fault lamp remains on. After 24 hours, the engine fault lamp goes out, but if I go again at a constant speed of 90-100 km, the same problem occurs again. The friend changed the injectors because of this problem, had the turbo complete maintenance, pump maintenance but the problem still continues. When we connect the computer to the service, the turbo pressure is low warning.

The Service cannot give a clear answer regarding the solution of this problem. But I doubt the catalyst. My friend has canceled the catalyst. But there was no sensor in the catalyst. I wonder if the problem could be caused by the catalyst. Well, the catalyst is a lot of money. I wonder if I change it. Or is there a friend who has come across such a situation and has found a solution? This situation bothers me a lot. I would like to thank the friends who will help you in advance.

Overhaul the charging dynamo ...

Welcome .. Get well soon ..

the same problem was found by myself in the service about 3 months ago, there was a small hole in the air hose of the turbo, and the air was missing, the turbo could not draw the air it wanted.

When I say the engine fault lamp, I think the yellow lamp that looks like the engine sign

That lamp means `` I pollute the environment '' or prevent air pollution.

is meant to mean

or lambda sensor is faulty

either the catalytic converter is defective / blocked / has expired

or petrol - diesel filter blocked

or dirty gasoline

If it comes to you after the contact is opened and closed, it is not gasoline.

one or more of the first three items

or all

The same problem was with me. Unfortunately, it is the chronic problem of HDIs. Turbo air flowmeter malfunction. I disassembled and went for cleaning. It has not been a problem for 4 months. If it repeats, I will have to change it for 170 TL. First of all, I recommend you to have it cleaned and observed.

Since the turbo campus of the 406s is a little different, I do not know the exact location, but if I think it is on track 6 .. By the way my car is 206 HDI (cancellation)

I was going to call a clogged injector, but you said it had changed
The cancellation of the floor causes the light to burn, but it is not the reason not to be knocked over
When you get the result, we would be happy if you inform me, I was really curious.

When the sensor fails for a while, the ECU thinks it is a false alarm. The light goes out, but when the wrong value comes from the sensor, it turns on the fault lamp. and the engine is falling in Guard mode because it perceives the fault as something important. Same problem in the summer.

Thanks for your interest.

Your valuable experience was very important to me. I will transfer and try all of your experiences when I go to the service. In these kinds of problems, when a person cannot find a solution, it creates a lot of frustration. The air flow meter made sense. Of course, catalytic convector, diesel filters, injectors, turbo also make sense, but all of them have been checked before. But only the catalytic convector was stuck in my head. However, as a result of my research, there was no oxygen sensor in 406 diesels. So they said they wouldn't make it from the catalyst. But I will definitely have the air flow meter cleaning done. But why is it only doing such a problem when driving in the 90-100 km range and the vehicle is under 2500 revolutions, and not another time. I'm going to get very interesting. But there is no other way we will try.
I will rewrite the result of let me go to the service from here.

Greetings; I am a user of 406 hdi, if you change the diesel filter cup, the malfunction lamp will not be a problem. Especially at the 3rd and 90th-90th speeds, it can be reached at high speeds. if you connect it to the computer, the problem is: if the diesel pressure regulator is writing the error, the exact solution is, do not count the money to the regulator ... its price is around 110 lira. Also, the malfunction lamp is lit or the performance is under the gas pedal, there is a round plastic eye, be careful not to mop it.

[QUOTE = ages] greetings; I am a user of 406 hdi, if you change the diesel filter cup, the malfunction lamp will not be a problem. if you connect it to the computer, the problem is: If the diesel pressure regulator is writing a failure, the final solution is, do not count the money to the regulator ... its price is around 110 lira. Also, there is a round plastic eye under the gas pedal for the malfunction lamp or performance performance. / quote]

we will be happy if you introduce yourself.
