Hi guys! Just a quick one, looking to do an oil change on my 2015 A220D W176. I’m guessing the sump plug is behind the under tray? Anybody know the location of it as I don’t want to crack open the gearbox fluid cheers sean
Some (maybe all) main dealers and many diy'ers use an extraction pump to suck the oil out of the sump via the dipstick tube.
It saves having to take the undertrays off and is just as effective at getting all the old oil out.
During my DIY years I did fit a sump plug magnet. I used to clean the fine metal shards of it at every oil change (though the physics says it's not needed it they won't be going anywhere....).
