Hi, my W211 MB has the tyre pressure monitor feature. Some time ago I had a new set of tyres changed to the car (changed from winter tyres to summer tyres). New sensors were installed on the new set of tyres. Now when the system is initialised according to the advice on the user manual, the car responds after a while ?Visit Workshop?.
The car did visit an official workshop but the local one really does not know too much of ?this complicated? features. They told their service tools indicating that the car should be driven 35 kilometres to get calibrated. However, after a few kilometres, the car computer again asks to visit workshop.
Would anybody be aware how a second set of tyres should really be installed on a car with RDC. Specifically, is the battery on the sensors connected ?off the self? or should something be done with the sensors before installation to the wheels (I?m thinking of an insulator that often disconnects the battery when the device is ?on the shelf?).
Is there a need to initialise the car computer to recognise a new set of sensors? If so, I assume the car can accept at least 8 sensors as it should be possible to change from winter tyres to summer tyres without a workshop visit. The sensors were installed by a tyre dealer, if they have an individual code that needs to be told to for the car computer, then I guess the tyres need to be uninstalled to find this information from each sensor (I never saw those sensors as my local, official workshop gave them directly to the tyre dealer?
I believe I either have to visit another workshop (I know one but I would need to drive an extra 100 km) or need to have some guidance from the news group for the local workshop, if there is an easy way to make them learn.
Thanks for any advice, a W211 CDI driver.
