Hi,
Just carried out a full service on my W211 E320CDI and would like to reset the service indicator.
However, on the main dash display in normal mode it says "Service display not possible"
and on the service reset page
"Calculating....."
How do I turn it back on?!
Thanks
Jon
does anyone know the formula to work out how to measure the sidewall on a tyre ie a 235 45 17 tyre will have a deeper sidewall than a 205 45 17 is this true or false and if it is true what formula do you use to work out running circumference of a tyre
