    Check the egr I had a sealed cord, which is pushed by such a rubber pear to which the tube goes from the top. The CCioner moves a flap that flows exhaust gas into one or the other channel. Now the car heats up very well and the valve is back in its original place. The fact that it loses temperature after a stop is a normal phenomenon, unless you take a longer piece as furious, then the engine with oil heats up more and gives off heat for a longer time.
    This is the element pushed below by a plastic link made of a rubber bulb at the top.

    It follows that there was no need to correct the factory

    It was not needed .... It is a shame that even ASO or other mechanics do not know about it, but just need to look for yourself. I will tell you that in the previous configuration, however, the downhill was a bit more agile, because the egr would not work, but the engine heating was worse in winter. Who likes what, I have to hide the car a second time out of curiosity to see what I will show.

    How did you start this stuck cable?

    I did it on Tunap 133 but I think some kind of damper cleaner or wd40. I wanted to unscrew the 3 screws on the other side of the string because there is the other side of the shaft, but I did not manage to detach this small lid after unscrewing the screws. Unfortunately, you have to play with it for an hour to get it started. Only when it starts to bounce, it means that it is good, i.e. the spring bounces inside.

    But he will kill himself with carbon deposits again. Only replacing the EGR will do the trick

    He will probably kill himself as it happens in diesel.
    Unless I am doing the car route and it is burned out, it should last longer.
    When it comes to cleaning such lubricant residues, a chimney cleaner is a good and cheap option.

    However, with this egr, did you clean it inside or outside?
    You mean the item I marked

    This is how the selected item is concerned. I separated the egr from the radiator and opened the flap. I did not clean it completely because mine was in good condition and there was no need to clean it.

    I would like to present my situation. Seat Exeo
    I noticed that when driving calmly, the car does not reach a temperature of 90'C, only when it gets stuck harder it will reach 90'C. Then when you drive normally again, it calmly drops to around 85'C and stays like that. In addition, what I noticed is that when driving faster and then normal at a standstill, the temperature will increase to 90'C, but just start and go and it's already at 85'C
    Now the question is whether this is normal behavior in the CR 143KM CAGA or try to replace the thermostats. It gets warm in the cabin without any problems.

    Hello, is your car pre-facelift or facelift? My year is 2013. CJCB, the previous owner replaced both thermostats, but it did not help. I found a guy on the forum who suggests reprogramming the EGR so that it does not release air circulation too early, which cools the fluid for "ecology". I wonder if your problem with the cooler concerns the facelift, because maybe it will solve the problem in facelifts. In pre-facelifts, it is enough to replace the thermostats and the three-way valve with OE ones. Possibly the EGR seatpost problem described above.

    In the policy, the above plus what I described about reprogramming:

    Everything will be solved by changing the software in the controller. I have the same problem. I'm going to the guy on February 3 and we'll see. I didn't replace anything because there's no need for thermostats. If they were bad, there would be no temperature while driving on the highway. You replace the costs, you do it and it's still wrong.

    After changing the software, replacing the burnt exhaust gas cooler every few months is an improvement. They limit the operation of the EGR pump and that`s it.

    Hello and how did you solve the problem? What happens after this software change? Because I have the same problem Audi A5 2.0TDI CR CJCD and I don't know what to do next, I replaced the EGR because it was clogged and it didn't work until I finally overhauled the engine because I had a problem with oil consumption, but it doesn't matter and I immediately changed both thermostats and so on. It's hard to catch the temperature, the temperature reaches 90 degrees Celsius when driving gently, and at idle speeds it drops and now the temperature is +8 degrees Celsius, so what will happen when it's frosty? The mechanic told me that it is normal that the temperature drops when stationary.

Topic summary

The discussion revolves around the issue of the 2.0 TDI CR CJCA engine in an Audi A4 B8 not maintaining the optimal operating temperature of 90°C during winter conditions, particularly when driving in urban settings. Users report that the engine temperature often stabilizes around 70°C, with fluctuations observed during different driving conditions. Several participants suggest that the problem may be related to the thermostat, specifically the small thermostat (part number 059121113N) and the main thermostat (part number 03L121111AD). Some users have replaced both thermostats with original parts but still experience issues. Others mention the EGR cooler potentially affecting temperature retention. Solutions discussed include checking the EGR system, replacing thermostats, and even reprogramming the EGR to improve temperature management. The conversation highlights varying experiences with different thermostat brands and the importance of using original parts for effective resolution.
