    Hello.
    I am asking for a hint as to where and how to get the ABS + ASC 34511164897 driver diagram - this one I have in my BMW Z3.
    The driver is still damaged. Under the influence of the temperature, several resistors were sold out and slipped from the raster. I sold them intuitively - they were right there, except for two. One I found inside the case. However, unfortunately there is one more resistor (clear assembly marks).
    I have no idea what value it was and it would be good to check if the rest returned to their places.
    Despite the fact that I do not do business with repairing drivers, I do not assume that one of the colleagues who are involved in their regeneration would like to share the experience, so only the scheme or experience remains (the worse scenario).
    In exchange, I will share a reliable photo - a description of the repair.
    Thank you, if anyone wants to help you. j @ cek

    Hello, thank you for silence. I had to deal with it myself. Unfortunately, I still do not have a schematic, but I will share my experience. The BMW designers probably have not tested the place and the way the pump was installed with this ATE 34-51.1164897 driver for a long time. They placed the whole in the "furnace" using SMD technology, and on the downside mounted the controller vertically. Under the influence of high temperature (in my case) the entire branch of 12 resistors floated from the raster. Not all of them fell into the casing, most of them were displaced in random positions and so solidified - of course on short circuits as a result of which the controller lost communication. First, I carefully cut the housing, and based on the traces in the soldering points, I fitted the resistors. Measuring their values I noticed a certain repetitive dependence - they were connected in branches parallel to 9.9k which resulted in about 4.9k and on this basis I picked up the missing resistor. I have deleted Carsoft 6.5 errors and now my "heels" are safe again. ABS (AbsolutnaBrakSystemu) with which I had the pleasure to deal with will be further improved by flooding repair sites with silicone HIGH TEMPERATURE 70ml - TECHNICQLL with Allegro 9.27 PLN. I will also protect the housing, I will only finish the test after repairing the controller - another week. I described this to bring the process of repair or regeneration of ABS controllers to mind, since I assume that most faults are. I think that a better solution would be to locate the controller horizontally and apply a through-hole technology, but this is advice for other forums. I greet the patient who is interested in this reading. BMW Z3 only 150KM j @ cek

    Hello, thank you very much for the warning, so I will only protect the enclosure so that it is hermetically sealed. In this version of the controller there is a vent in one of the corners - at least it looks like it. So actually, paperwork in the middle can make a difference. Thank you again. The driver, of course, works fine. Regards Jacek.

    Well, if you've helped me, I'll tell you where you sold the varnish on such engines, you can buy it in every engine rewind facility. 60 PLN / l buy 50ml. Otherwise, it will bloom once a year.
    I am repairing the drivers and I will tell you so.

    I did not expect an answer. It is an honor for me to correspond with an experienced forum member and I am also pleased that a real master has spoken. I admit in secret, I wanted it so that's why I wrote these posts in this way. My faith returned to people who were not only profitable. Thank you very much for your help.
