hi, would anyone be able to tell me if the audio unit is connected to the main computer , as it seems sometimes i have difficulty connecting my phone via bluetooth for music and after several attempts i then get some engine codes come up , is it just coincidence ?

There is a radio module that MAY be connected to the CAN BUS network. If the ECM codes are network codes, then they MAY be related. What are the codes?

And how old is the battery?

I had a radio upgrade/change done recently and it enabled a multitude of items through the radio. They are definitely computer connected.

I doubt that P2135 was related unless you are just having an overall low voltage issue. I don't think that communicates over can bus network. And I'm not sure that the the radio communicates over the same network as the ECM. Unless this is a low voltage issue, I doubt this is going to be solved over the internet. Freeze Frame data from the trouble codes needs to be reviewed when the codes are set to see if that is an indication of what is happening.
