peugeot 508 CAN problem ?

[barteczekk]

Hello. The car is a Peugeot 508 SW 2.0 HDI 163HP from 2011. The gearbox stopped working in the car. It was repaired. The car has driven about 150 km after the repair. The problem is that the car changes gears for about 1 minute. Then the gearbox shifts from D1 to D5 and that's the end of the drive. The last time I was able to scan all the modules in it using x431 was in January. The report is attached. Now x431 does not find BSI and many other modules, in fact it probably only sees the gearbox and the rain sensor. After connecting Diagbox 9.150 it finds all the modules but they are full of CAN communication errors. u1213 u1109, u1209, p2711, it looks a bit like the car is driving until the CAN network goes crazy. I checked the resistance of the gearbox controller, power steering, bsi, abs, ecu, everywhere 60 ohms. I checked the cables, resistance 0.5 ohms. I tried disconnecting subsequent modules to get the possibility of using x431i scanning the entire system again. So far without success. I replaced the BSM with a used one but no change.

Hi, are you sure that they correctly assembly your gearbox after repair? I'm asking as you have 2 errors from 2 solenoids, I have such issue in the past, someone put wrong solenoid to the wrong place. It was different gearbox but maybe you have similar issue.
