Hi All,
I have an E500 Convertible and the aircap has started to play up. when retracting it gets about half way closed and then extends again. have searched all over but all the reports are go to Mercedes and they will replace for over £1000 it would seem.
Well as it was a nice day I took a look at mine. I removed the aircap from the car as per the following link
when I had it on the bench I was able to remove the motor section. very simple issue, corrosion on one of the arms was stopping the locking pins sliding out when it was retracting and it was causing the pin that moves to hit the locking arm at the wrong point. you will see this in the attached picture
provided lots of oil on the joints and all working again.

Hi, can this be lubricated without dismantling ?

E350 CDI Cabriolet just replaced my 997 C4S
I had the same issue. I cut the offending pin off with an angle grinder. Works perfectly now.

Thank you for this! That is exactly what I was looking for. Same as OP I spent hours searching (last year) only to find 'needs replacing for £1000+'. Or one person suggesting a software update would do it?

@thebook did you need to remove it completely to access the offending pin? Where is this pin located. Apologies if this is a silly question, the previous owner disconnected it and I've not yet been brave enough to put it back up and take a look.

Thanks
