I bought a R170 about Two months ago, i noticed that my boot would open and my roof would not come out and go back up.
this happened intermittantly and sometimes the roof would not open but the boot had opened.
I took out the boot open switch and this worked properly.
i had the car
connected to a computer at a local Benz specialist garage.
the car had lots of errors on nearly all of the switches,i had them all reset and had the front switch replaced thats under the sun visor.
Well this weekend i was in brighton and went out and about, the boot opened and the boot would not come out of the boot, i tried it about 30 times. went for a drive and tried it a few more times.
i got back to my starting point and the dame thing worked
i noticed that when pushing the button it did look like it was trying to lift.
the hyrralic pump fluid level is showing its between the min and max.
the garage i went to said they have replaced the switch under the visor and now the next step would be two replcae the two switches in the roof lining,
my questions are
would the roof look like its trying to lift? (moves/jults with press of button)
does a dealer have a roof diagnosis process that would be better than trail and error of changing switches?
would another diagnosis tell me whats wrong with it now all of the old codes have been cleared?
Please help give me some idea's
