VW Passat B5 1.8T AEB - The turbine turns red after replacing the exhaust system

Hello all. I know there were similar topics but no concrete solutions. Yesterday, in my Passat b5 1.8 T AEB, I replaced the entire exhaust system, including the catalyst, and replaced it with a replacement.
After this treatment, the turbine began to turn red. This was not the case before. After a harder ride, it glows red, and after a quiet ride on the 110 - 120 km route, it is also a bit red. After replacing the kata, the car has not gained much strength, it is a bit more lively. I don't like that turbine turning red, I'm afraid I'll finish it soon. Have any of you anyway? Maybe you solved the problem somehow. Nor does he want to spend a fortune replacing everything one by one, which sometimes won't work. greetings

If the batch is not chiseled, put the catalyst back.

The worst thing is that it is raining today, but I think I'll do it and see it then. Damn, but it puzzles me a bit, because the turbo should be lighter now than with the executioner.

Have any of you had a similar problem and solved it?

this is exactly what this catalyst replacement looks like

Added after 2 [hours] 20 [minutes]:

I sit and think like that, I take everything logically, the first thing, if I had problems with the fuel mixture or something else, such turbine symptoms would be before removing the catalyst, and now the second thing, if the catalyst replacement would have problems with the flow exhaust gas and was the reason for the turbo to heat up red, the power would decrease and the car would be weaker. What do you think about it?

One more thing wonders me if the n75 valve can affect the blushing of the turbine? Today I did a little test, disconnected the plug from it and didn't feel any big difference when accelerating. Apart from a bug in the vagu, nothing else was there.

Hello, can someone help me or maybe someone has already had such a case? Today I put the catalyst back on and despite everything, the turbine also turns red. I know that with sharp sawing it can do, but with normal, ordinary driving on the road, it should not be 120 km / h. I will also add something interesting. I detached the n75 valve and I did not feel the difference in power, well, the car was a bit weaker, but it was walking calmly and on the section on the runway 180 flew calmly, just like with the hooked up. After unfastening this valve, the turbo also turned red.

How about the probes?

Well, I don't know, I don't know too much, I read somewhere to make logs on channel 002.007.025, but nobody wants to check these logs for me. I was making logs as there was a replacement for the executioner. Here they are

I am surprised that there are no big differences after removing the n75

Certainly it has been broken, I do not know if there are any problems with the turbo, I am not closing the topic, I will describe new things. It turned out that the turbine is not pumping to the end as necessary.

The flow meter and dv valve are common faults.

See how the ignition timing changes.

I checked the dv valve and it is ok, the flow is different, now it shows the values, although the mechanic said that it was not exactly as it should be. Hmmm, how to check the ignition advance angle? Speaking of flows, you can do some vcdsem logs? to show you?

I do not know if there is a problem on the turbo itself, today we looked and yes, one that it has cracks inside, two that it takes a little oil and three that it does not give a very good boost, the mechanic grabbed the hose and did not feel it gasped Let the snake get a little puffed up, so to speak

This is what the turbine looks like from the side of the kata, the warm side, there are cracks inside; /

Added after 49 [minutes]:

I still have such a purely theoretical question, because I will not do it, due to the fact that the turbine has cracks inside and it probably cannot be done, but tell me if you can buy repair kits for what is inside, i.e. not to she burned oil etc? is there such a thing? I know this is a stupid question, but whoever asks does not err.

I am asking, because if people exchange, regenerate funds, it must be something like that?

Added after 2 [hours] 36 [minutes]:

what about these cracks anyway? marked in the photo?


I saw on some other forum, photos of the turbine and someone had almost similar cracks, what do you think about it? is that what to worry about or not? PS. I found repair kits on alledrogo, is it worth resuscitating the turbo in this way?
