8 months ago, my reverse camera was only showing a black screen and the car had random issues, cooling fan running at full speed intermitent, super slow unresponsive Idrive, airbag light on and off intermittent.

In Ista, 3-4 modules were'nt responding, but as soon as I disconnected the TRSVC module (reverse camera module under the dash, driver side) everything was back to normal.

I bought a used module on ebay, installed it, coded it in Esys. Everything was back to normal. Today, 8 months later, same issue again?

I removed the module and everything is back to normal, as soon as I reconnect the module, same issues happens.

I bought a brand new original BMW battery and installed it just in case (I still was on the original battery), didn't solved the issue.

I ordered another module on ebay and i'm waiting for it to arrive.

I am missing something? don't understand whats happening now, is it possible something like the back up camera itself is making the module fail?
