There are mistakes, it should be: 0YJ 0YK 0YL 0YM

HI! I can't find information about rear axle ranges - i know the PR codes and part number for the springs, but i don't find DIFFERENCE in kilograms between ranges (or the range in kg for the selected range). For example: (for audi A4 3.0 TDI Q avant, B8 with PR: 1BE-sport suspension) ->By default there are springs PR: 0YJ (8K0 511 115 HA) What is the weight range in kg for the axle load rating 9? (for example "x" to "y" kg) OR What is the diference in kg between OYJ and 0YK (or 0YK-0YL or 0YL-0YM)? I found somewhere for B6 that it should be 22kg between ranges...?? I need it because there is new westfalia towbar installed on the car and there is also 50kg of other tools all the time back in the trunk. So the car is a bit too low at rear (with OEM springs). Now i need to calculate which weight range to select for new springs (HB, HC, HD ...). (HA is the "thinner spring and the HD is the "thicker") Rear springs: 0YJ - 8K0 511 155 HA - axle load rating 9 --> x to y kilograms 0YK - 8K0 511 155 HB - axle load rating 10 --> + xy kilograms (maybe 22 kg) 0YJ - 8K0 511 155 HC - axle load rating 11 -->... 0YJ - 8K0 511 155 HD - axle load rating 12 -->...
