My RS finally died last night for apparently no reason....

Did six laps towards the end of a race as I missed the start, car was perfect and then just died. Was still on and showing one on the temp scale but smelled terrible and the car barely moves.
Does anyone know where to send it for repair? Tekin website is currently being updated.
It was originally purchased from Ardent about six months ago, but I dont have the reciept so not sure if I can take it back or not...
