Standup resistor mod DIY ?

I saw the link to the resistor mod DIY on google from M3forums, but unfortunately that is now gone... anyone have a backup?

there’s a few threads on other forums on which resistor to use. I used a 1k but that was on my previous m3.

interesting

Is this for SMG cars?

Optimal value of resistor to use for the mod is 680 ohms, as identified through extensive research by Steve Evans.

This is right. I'm using the 680 ohms based on the information from M3F. It's not too much. I've relocated the SMG and I've still left the resistor in and it hasn't messed with anything.

I'm still not convinced that this mod has any benefits unless you're seeing a specific code about the temperature being too hot. However, it probably is a reasonable precaution to take if drive-ability is your highest priority. Any SMG experts want to weigh in?

[Good]

The resistor mod is NOT a solution. All it does is reduce the temperature sensor reading overworking your unit. Fluid temp increases, internal and/or external leakage occurs. You must maintain your hydraulic unit by replacing the hydraulic units internal and external seals.

I agree, this just prolongs the inevitable doom of the SMG pump.

I wouldn't do this "mod".

Hi huys, what number of pin on the unit in the engine bay it is pls? Thank you so much

It should be pin13 of the 40-pin connector X53004

This "mod" will only fast track SMG motor wear. You probably have internal pressure loss. You will need to either replace your SMG pump, or rebuild with fresh viton seals.
