Hi wondering if someone can help me, iv noticed that my heating is taking longer than usual to worm up so I did a scan. I got the code 90B387 (electric heater booster has a malfunction. The message is missing) so I'm guessing it's the electric heater. Can enyone tell me where the fuse is and where the actual heater is please?
