Hi, I also have de manual and the schematics, but as you say, none of the sensors are numbered. The 7 led's sensor socket are identified from A to G. The SL1E to SL7E sensor reports that it is short-circuited or open... So probably, the problem must be in this area, I will change the LEDs position and check if the problem goes to another number. Thanks As you've discovered, the manual says: SL1E - SL7E(Sensor error, sensors 1 - 7) ...a sensor reports that it is short-circuited or open So in your case, sensors 3 and 4 are faulty (or possibly the wiring/connectors). Is there any indication of any crushed looms or wires, in the first instance? I've got the 350 Entour schematic here but unfortunately none of the sensors are numbered so I can't see what 3 and 4 relate to... I'll keep looking. Hope that helps a tiny bit.
