I've been working hard to find a Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected.

I wonder whether you're ok with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you.

Thank you,

Hello and Welcome -

My name is MIKE - Im happy to help you ...

This is unlikely to be any relay fault as you have the fault you describe and no washers...they are separate circuits - but work through a "computer module"..

You may have two separate faults though - one being the rain sensor itself - or the module..or the motor ( it is impossible to say at this point without tests ) and the other is a faulty washer pump for the front - or simply a blocked line to the nozzles..

Given these issues, you could have the washer system checked quite easily - any small type garage can do that for you - as to they can deal with the rain sensor issue - by way of testing etc - but you may find that you will need BMW equipment ( to test ) the module /computer if the rain sensor proves ok - If the garage you use doesn't have that - you will need the help of a Bmw garage - at least to run the tests and then go from there..
Let me know how you go / if you need anything more - Im sorry its not straight forward for you - but that is the way forward on this one now -

Kind Rgds, MIKE.
