00927 - terminal 30 (right)

Car got serviced just before Christmas, oil, filters and brake fluid were changed and battery health checked. Next day I started the car and the dash said a bulb was out. Go and look and it's driver side main. Weird since I'd changed it 3 weeks ago but put it down to bad luck. Went to look and it was fine. Changed it anyway and it worked. Few hours later the light comes on again only this time it's the whole of the passenger rear cluster. All off apart from the brake light. All the bulbs looked fine so went to go out and get some bulbs then after a restart they were all fine again. Last few days they've been intermittant. I put ignition on and it flags a bulb out, I turn ignition on and off again and sometimes they come back. I watched in a shop window reflection the DRL's being off on one side then turning on.

Scanned for codes using Carista and get 00927 - terminal 30 (right). Guessing first port of call is the fuse and relay box under the bonnet? Battery is 6mths old and is connected OK. Anyone had this before?
