Hi Folks, My 2005 E270 is currently on just under 150,000 miles, and to my knowledge has never had the gearbox oil changed. My understanding is this should be done every 70k or so. I've spoken to Coverdale in Newton Abbot about getting it done. They tell me that aside from main dealers they are the only place in Devon that have the equipment to remove the old oil. I'm not familiar with how it's done, or whether it requires specialist equipment, but they told me it would be about £350+VAT. Does that sound about right? Thanks in advance!
