Renault Megane immoboliser?

can anyone help? If after turning the ignition on and waiting a second or so both the red flashing light and the immoboliser light should go out, if the immoboliser light stays on, the car will start, but if it goes out the car won't start as if the immoboliser is set. Any ideas please

Check for water damage on pick module above rear view mirror,
unclip unit from plastic holder,disconnect and rub off any whiteish deposits from pcb, SHORTING OUT PCB

I have now placed my pcb in a clear plastic bag & sealed with sealant then, I modified the holder so I can put the connector block on before it is refitted into the holder without puncturing the bag.
it seems that water drips onto the pcb from antenna & or sun roofs and in some case can cause the key not to respond and unlock car and dump the codes in the ecu, I had to recode the ecu to the key as well ,change the batteries for new ones be quick as you only have about 30 seconds or synchronisation of key & ecu can be lost !!

Trust me mate. I had the same problem and I asked all kinds of people. But the fact of the matter is your immoboliser is inbuilt into the ECU and I had to change mine. But my advice is get a second hand one WITH REFUND OPTION! because they ain't cheap or easy to fit. Sorry
