Not all TCU versions can be used for your car. You should enter here actually mounted TCU Hardware Number (stamped on TCU). Each TCU requires different Software, even for the same car, because all of them have different memory size!
It is critical to use proper EHS number! Mismatch can result in poor shift comfort and lock-up issues. EHS Number is stamped on the side of valve body. This Numbers change with introducing of new TCU versions (e.g 2202701306 changed over years to 2202702706). In case of TCU replacement always observe valve body symbol (e.g. A39_N_PLATTE) It must be the same for old and new TCU version!
