Every warning light coming on....

Good Afternoon,

I am having a strange issue with my 1 Series, I took my car through an automatic car wash and ever since then my speedo and rev counter drop to zero when driving and then back up again, every possible warning light comes on with a beep and now the flat tyre warning light and reversing sensor is no longer working!.

Has anyone got any suggestions as to what could be causing this issue?.

Thanks in advance.

Steve

Did you find a solution to this problem as my 118d has EXACTLY the same problem after a heavy downpor yesterday.

THis is a long shot, but there have been reports in the 5-series forum about water drain lines in the sunroof becoming plugged. This leads to improper drainage and water is getting into the trunk where all the electronics are located, causing all kinds of warnings.

I don't know the 135 as far as where the battery, electronics, etc are located, but check and see if there are any signs of water in the low areas in the trunk and wheel wells.
