    Hi all, I changed the differential oil today and thought to share my experience. First of all, I discovered that my car does not have a drain hole, only a fill hole. Luckily I have a fluid extractor pump so I used that to remove the old oil - about a litre. I then topped up with a Laser...

    Hello all, My 2007 E90 320d is now at around 150k KM's, and never did the diff oil change. So, I changed that. Afterwards, I noticed a very small leak around the drain plug. So, I bought a new plug (plug + O-ring combo) from eBay. The new plug, not sure if OEM or not, came with a new green...

    I'm trying to liven up my manual e36 328i and I've read that getting a diff with a shorter ratio can make the car a lot quicker. Most suggestions were to swap in a 3.15 from a 325i or m3 however, in Australia, these diffs are hard to come by and are REALLY expensive. However, automatic 6...
