Hi mates... I am new to ecu remap and trying DIY my 2.5 tdi c5 4b AFB.

I Ordered a mppsv13 cable and tried obd2 but it give me a error because of fuse. removed all fuses and dash still work and give me the same error. So i heard that this type of cars just work on the bench.. So i removed my ecu, and pinout the obd2 cable with a batery charger 12v 4amp and ecu but wont work... mpps program show difrent voltages and dont read.

I connect the ground , 12v, and k line to obd2 cable. k line going to ecu pin, and I suply 12v to ignition switch and power pin on my ecu and all ground pins too. Really dont know whats wrong... mpps software showing 0 , 7, 17v, 13v, 14v, allways changing.

If u could give me a light I ll be apreciated (sorry for my bad english)

Tks in advance

ok update. allready found out the problem of no stable 12v... need 2 more 12+v suply for feed ecu. Now looks when I connect it on the car... read ID, but when I choose to Read ecu it gives me same fuse error.... anyone can help? tks
