Tristan, yes check that relay. On the turbo the radio suppression relay is mounted between the battery and the driver’s side headlight. There are two identical black rectangular relays. One is radio suppression and the other controls the cooling fan. I would just switch them and see if it makes a difference. If not you can test them with a test light to see if power is going through. I have had to change mine so if they are the factory original it could be an issue. ┬áTry the swap first.
