As far as I am aware, DCC only has an effect on the shocks and not the suspension height.

As far as I am aware you can't set TPMS while the engine is running. This should ensure that you have stopped the car and checked the pressures.

Totally the Merc at fault. Reversing out without checking what's there.

Do you have personalisation eneabled?

A good USB cable is a must, but will wear out the phone connection eventually. There are several wireless adapters that will give you wireless carplay.

Purely from personal experience, I would recommend the AA Wireless dongle. Had one for several years and had no issues whatsoever. Itregularly updates and reboots without problems.

Have you tried using a 2032 battery? They are slightly thicker, 2.5 mm v 3.2 mm, and put more pressure on the contacts.

Apologies, my mistake. It's the VRS that was diesel only.

if 4x4 it will have a differential at the back. Has it been written off?

Are you checking reg plate or chassis number?

A quick look under the rear should clarify 4x4. The 4x4s only had the diesel engine.

Do you have electric memory seats? I believe the dipping mirrors won't work unless you have the correct seats.

I'm not sure why you think that the 2.5Ghz and 5Ghz bands should have different names but they should be part of the same network allowing the phone, and other devices, to connect to the best signal.

Sadly, my brain can't remember the details, but I probably used the website. However, your phone only connects to one wifi network at a time. Your home network may be stopping your phone connecting to the AA Wireless network.

I have used the AA Wireless device for some years and have not had any issues. Once setup it simply connects to my phone when I get in my car. There are some cheaper options which have been used by others without problems. Good luck with your search.
