Hello and Welcome to justanswer..

Im sorry to see you have had a wait on your question -

As you have done and checked all that you have - as you now have the LIM and other lights ,your next step has to be to get a code reader machine connected to the cars diagnostic socket - and see what fault codes are logged in the Ecu - that will point you to the fault/s that you have causing your non start...

It could be that you have an immobiliser issue - I suspect that at this stage - but you need to do the above to progress / get this sorted for you -

I strongly recommend using someone who has MB equipment or similar- mobile auto locksmiths have the equipment that can check all this for you and deal with any immobilser issues too -

So you have gone as far as you can on your own with this now - it is going to need the equipment plugging on as above to trace / sort this for you now... that will one way or the other, soon have this sorted.

I'm very pleased to have helped you... let me know if I can help anymore...
