What exactly was the error called? Or do you still have the code? Without a description of the error code, it is unfortunately difficult to make any further statements.

Hello, can you tell us exactly what kind of vehicle you are driving? Because as I can see from the error codes, you are driving a BMW with an all-wheel drive/X-Drive system. Have any repairs been carried out on the transfer case recently or has the transfer case been checked, especially the plug connections?

Hello Benny it is a bmw x1 e84 2009 xdrive 3.0liter petrol has now exactly 180'000km it actually drives great no problems like before without the problem on the transfer case was never done what the previous owner told me he wanted to program it but without success may be due to the water do not know now yes now with carly adapter he shows me some error codes such as.e.g. 005F3A,006F8F,00CF80,00521C,00521E maybe it's just a small problem and the errors clear themselves after the repair but I really don't know what the problem is or if it just needs an oil change in the transfer case I really don't have a plan need help

Hello, so if software is installed on the car to delay the thrust cut-off but it has no effect, the engine control unit should of course first be programmed back to "standard status". What I know about the transfer case is that the plastic gearwheel for the adjustment (front axle and rear axle) wears inside and therefore the adjustment no longer works as usual. In my opinion, you would notice this when driving (vehicle jerks when cornering and does not behave as normal). Nevertheless, I wouldn't rule it out across the board. These are the error texts for your errors: 005F3A - DSC: Transfer case: malfunction 006F8F - Message (HDC button operation, 0x31A) missing, DSC receiver, IHKA transmitter My suggestion would be to replace the "DSC" switch, i.e. the switch in the interior with which you can switch off the DSC, or to remove it and check whether something has run over it (cola or something like that) If you have a multimeter, you may also be able to test the switch with it.

Hi the switch has been tested with multimeter it works and when driving it drives great like it did at the beginning I really don't know what it could be

Hello, If the switch is also OK, the next step is to check all cable connections from the switch to the control unit (ABS/DSC, X-Drive system) using a multimeter to rule out a faulty cable connection.
