Thanks for all your feedback, my little mk1 is sitting parked atm with the following errors P1648 P1644
This issue is messing with my temp reading with my obd2c&c gauge reading -30 battery temp
This is a very strange issues where ive had the temp display at 24degress and then back to -30
Just to be clear, ive just recently changed the ptc strip resistor to a 82ohms 1% resistor (another member test 85ohms and was not issue with the ptc strips)
For the 4 oem temp sensor i put all 4 temp sensor wires in parrallel and am using now a 2.5k 5% resistor to trick the battery temp at always 24degrees
I dont know if the temp mods have caused something to go wrong but it hard for me to tell
I originally ran the 4 stock oem termal sensors from the stock pack with the ptc strip resistor at 24 ohms, this worked fine during summer months, however with the temp coming close to 0 degrees i noticed less assist and regen, this is why i modified the sensors with fixed resistors to simulate a fix temp
I have a spare mcm and bcm that ive modded for peters 33% hack, however i will unmod it to try to get things running fine first
Ill keep you guys posted, thanks for all your feedback

Is that 0.82 ohms or 82 ohms? Anything between 10 - ~ 350 ohms should be fine. Edit: found your post above where you said 82ohms, 1%. Btw, resistor tolerance doesn't matter in this case.
On those temp sensors, I would split them out as they are normally wired. A common leg, with each sensor having its own dedicated signal line. Better yet use real sensors instead of resistors. The only other thing, double check and make sure you don't have an open signal line. The PTC and sensor wiring is pretty simple.
