Got problem with remote key fob not working! Changed batteries, can see LED
light up on FOB but not working to open doors etc. Tried re-sync' the new
batteries as written down in manual - no luck!
Also, on same fuse is boot light which is not working!! Bulb checked OK,
fuse replaced, no change, is that a clue maybe? Where is the IR
sensor/control unit?

Lastly, has anyone have access to electricial wiring diagrams for the
300SL-24v please? Willing to buy if reasonable price. Thank you very much
for any help out there.....

Let the dealer fix it before you make it worse. It can be bad keyfob.
