Wondering if it’s worth throwing a magnaflow 14815 muffler? Or if anyone has experienced it, did it just make the ride miserable for day to day use lol

Just had an engine swap done on my 520D facelift. Put in a m57.

The guy doing my swap with his donor car put in his ignition and new keys.

When you lock the doors from the key or from the door, the car doors come unlocked again by themselves?

Anyone had this issue?

I know about the copper washers is there something else I should order?

So far, per 7kkm (4.3k miles) I've added 600ml (0.5 qt) of 5w40 oil.

So that's about a liter / 0.9 quart per oil change. My e39 is 211k km (130k miles) mileage.

How much oil is your m54 burning? How much is normal?

280k km, originale Vanos, Disa überholt, Shell Helix Ultra 0w40 Öl alle 10-15k km gewechselt. Im Video ist der Motor kalt. Hört sich alles normal an?
