Thanks both for the reply.
Yes it seems a little out of hand for my knowledge now! I've booked it in to VW a week on Thursday to look at the battery and the subwoofer - I'm doubtful they'll look at it since I've changed the radio - either that or they'll charge me a fortune. (I didn't tell them I changed it over the phone!) Well the issue isn't actually with the unit itself, only the subwoofer they installed but again, it was working with the unit that should be in the car so I'm doubtful.
Regarding the coding - I did use the long coding helper in the end for my MIBII comparing with my MIB1 (It was a late 2017 unit, I could only change the numbers in the code manually on VCDS) but the issue with the sound is nothing to do with coding (I don't think) because as mentioned the helix requires the internal amplifier of the unit.
I am returning my MIBII DP now anyway and kept my MIB1 DP installed (Personally don't think the money is worth it for additional features)
If the dealer fails or refuses to fix the issue then I might just have to revert back to my Composition Media system which sucks - I've gotten to love the Navigation System and bigger screen!
