E90 oem spring code/part number conversion

berkerb996 · 07-03-2014, 08:05 AM

Does anyone know a source for matching BMW oem spring codes (such as C4,D3,D4,T3) and their spare part numbers?

My car is a E90 LCI 320d, and according to my findings so far I should replace my C tagged standard springs with D5 front and D4 rear spring, but I couldnt find the spring part numbers.

Thanx all..

I would like to know too, especially for the "T" codes. Recently I asked a vendor about the bmw performance springs, they took my VIN but only gave me part #s, no spring codes. Part #s they came back with were:

31336788892, front
33536788901, rear

this is for a 07 e90 328i with auto trans. I suspect their codes are T3 front and T4 rear....but it would be nice to know for sure since they trade used from time to time.

has some observations on part number and T code, but it's not definitive and I don't think it covers all possible yellow spring part numbers.

I can't recall any posts from anyone, pairing spring code to part number for C and D...maybe because they're rarely bought new?

So it's an Easter egg hunt and if we ever figure it out, make it a sticky for sure....we need to find the Ed Snowden of BMW to help us out.

Here is what I found so far:

Front:
31 33 6 767 368 - C5
31 33 6 767 376 - D4
31 33 6 767 377 - D5
31 33 6 767 378 - D6
31 33 6 788 893 - T3
31 33 6 788 894 - T4

Rear:
33 53 6 767 345 - D3
33 53 6 788 901 - T4

T3 front and T4 rear info is taken from a post of Mr. 5
Please add any info to the list, or correct if anything false.
