Help Please 🙏
Hi everyone, i would like some help please, i have a C250 BlueTec, 2014, The battery was knackered, it went that bad it went totally FLAT. I had to buv a brand new battery, like for like, an AGM one, i also chanaed the auxiliary battery aswell. But i remember the trouble was before that though, it was a nc communication, no start, na crank. I believe a code started showing PTCM, I believe Anyway auto electrician ooked at it for me, spent hours on it for me. and he found the PTCM a had no live feed to it. so I don't know if something created that mate Anyway, I asked the bloke if he could run a positive feed to it to enable me to have it running, anyway he managed to do that and then it allowed me to start the car. It originally came up about the powertrain module. I believe that is the PTCM isn't it ?? I pelieve he said it wasn't authorising the car to start Could that be a bad front sam at all mate ??
