Mercedes SL500 R230 Trunk soft close fix

If your trunk soft close isn't working, the air pump circuit has probably timed out due to a leak in the soft close actuator. Here's how to take out the actuator and fix the leaks.
You can buy the black hockey puck actuator new on ebay. Just search "mercedes trunk Actuator Servo" and you will find them for around $54.
To seal the leaks, an epoxy for plastic would be best.
