Check the exhaust side of your valve cover gasket for evidence of an oil leak. Burning synthetic oil tends to smell like hot plastic.

try new switch or motor

Hi,
I think that if the battery went completely flat the vehicle may have lost the security code, or the same can have happened if you did not follow the boost charge instructions when starting. If that has happened you'll need to have the unit re-encoded by a dealer. Keep in mind that starting a vehicle periodically is good but if you don't run it as well the battery will become exhausted and finally fail. The start up of any engine drains more power from the battery than any other operation. You need to start it and give it a run.

There are a number of switches that need to be closed in order for the motor to operate. In particular there's a microswitch in the hood just above the left-hand seat which makes sure the motor doesn't operate until the hood has been lifted slightly.

My hood stopped working and I found the cable to the microswitch had been cut by the hood mechanism. Replacing the cable solved the problem.

Check the small microswitch on the LH top raol at eye level.
