XSeries-forum

Just had a great fix on the window now I must pay with something else. The intermittent wipe has gone again. Put the Alpina relay in and no difference. Put the X5 relay in the Alpina and it works fine. So not a relay problem. Anyone have any suggestions. I have checked fuses. My next move is to replace the wiper stalk because I have a spare one. Following that is to remove (don’t know how yet) the cover from the rain sensor and apparently there is a plug behind there which if you disconnect will give you intermittent wipe just not rain sensitive. Better than nothing if it works.

Try this…..it should allow you to get to the rain sensor. Then the sensor… If there are any signs of bubbles in the special pad, or fogging / discolouration of the sensor than that may well be your issue. The pad is optically clear and attaches the special element to the windscreen. You may still be able to get replacements from BMW and I expect any windscreen repairer would have them.

Thanks for that, very informative. I’ll post up how it goes. Let’s hope my next post isn’t about windscreen replacement.
