It is a specific item for the S1. S2 relays are different.

Finis Code: 1630562 Part Number: V85AB9P704BA

Have a go at bridging the relay before you go buying one though just to make sure as the relay is £40.00 and electrical items are non refundable.

All you need to do is unplug the relay and bridge pins 87 and 30 and then start the engine. If all is good then thats your fault.

Good luck
