Here are addresses for VWK501 (VWK503 in brackets when it is different) clusters: - 0x065 - speed source setting (0x80 - gearbox sender, 0x81 - ABS) - 0x08A [0x0C8] (3x1 map) - number of keys (you have to divide by 11 as it has 11, 22, 33... values), value is stored 3 times - 0x145 [0x187] - fuel consumption correction (0x64 - means 100%, no correction) - in IMMO2 clusters it used to be adjustable using adaptation channel - 0x150 [0x192] - K value stored as LoHi 16 bit number - 0x1D2-0x1D3 [0x204-0x205] - buzzer sound frequency (2 8 bit values) - 0x1D4-0x1D5 [0x206-0x207] - buzzer volume (2 8 bit values) - this one does not seem to work at least for me - 0x1D6 [0x208] - another setting for buzzer (length of the sound) - 0x1ED [0x21F] - lower 4 bits of this byte sets what are iluminated upon switching ignition (0000 - no ilumination, xx11 - displays, x1x1 - gauges, 1xx1 - needles, to combine just sum bits) - 0x1EE [0x220] - cruise control lamp setting - when set to E9 it works when CC is switched on, when set to F9 it works only when CC is actually working - 0x200 [0x238] (2x1 map) - 2 8 bit numbers which determines when (temperature) information about slipery road is displayed - 0x230 [0x268] (8x1 map) - 16 bit LoHi stepper motor map for speedometer - 0x248 [0x280] (4x1 map) - 16 bit LoHi stepper motor map for tachometer - 0x270 [0x2A8] (8x1 map) - 16 bit LoHi conversion between fuel tank sensor and fuel in litres (I am not sure how to tell if axis at 0x250 or at 0x260 it used [0x288/0x298]) - 0x290 [0x2C8] (8x1 map) - 16 bit LoHi stepper motor map for fuel gauge - 0x2A0-0x2D3 [0x2D8-0x30B] - it seems that even Golf cluster has maps for oil temperature and battery voltage gauges - 0x2E0 [0x318] (6x1 map) - 16 bit LoHi stepper motor map for engine temperature (you can correct it to show real temperature, not 90*C between real 74 and 108*C) - 0x416 [0x44E] - set it to 0xE1 to activate showing range/RKM/miles to empty - 0x417 [0x44F] - set it to 0x6B to show Welcome message (only xxx 920 x4x full FIS clusters)
