BMW E34 540i
Hi there
I've got the service plan with Bristol Street Motors Altrincham / Nissan, Renault. Car was on the second annual service on Friday - odo. circa 20K miles.
Wanted to install the itg panel filter now and saw the current state of the air filter. Full of dust, sand and generally looks old - meaning it doesn't seem to be touched. (Frankly speaking I was expecting to see brand new clean filter ?)
Is anyone able to advise what is the air filter service interval ? I have not got any invoice from them to see what exactly was replaced ?
Should I go back and ask for the list of what was done ?
