2014 C250 (W204) Turbo Oil line Leak

Does anyone know the part number for the seal on the turbo oil line as well as the part number for the washer on the banjo.

Part 271-090-0477 is the complete turbocharger oil line with the seal and the banjo bolt on the other end. Note that the banjo bolt is a revision from the original.

hey @WWrig - here is the part number from Mercedes for the turbo oil feed line. My local MB dealer had one in stock.

A271 090 04 77 - this came with the new banjo bolt and new o-ring that leaks.

I just replaced this on my car and uploaded a video to my YouTube -

@WWrig - just an FYI- there is 2 crush washers that are needed for the turbo oil feed line on the banjo bolt side.

FCP only provides you with one crush washer in the repair kit, where as Mercedes provides both crush washers for the banjo bolt with the new line.

I purchased the repair kit from FCP as well as, the new oil feed line from Mercedes.

i go over that in the video I made.

MB dealer is probably the best option if you just need the washer and o-ring. The 6513 part is $3.70 and the 8548 part is only $2.70. At least thats what its showing at my local MB parts dept. The bolt is $14.
