Difference in TPS P/N's (Early Prod. 325is)

[Snowmann]

Looking at TPS's for my early production 325is I come up with the following

Part pulled from car: 0 280 120 310

RealOEM: 13-631-710-559

Pelican Parts: 13-63-1-710-559

BavAuto: 0 280 120 321


I'm pretty sure the 310 has been superseeded. I can't find that number anywhere.

So which is it... the 321 or the 559?

If I put in the 559 number @ Bavauto I come up with the "this part doesn't fit your car" spiel...

Im confizzled

I sampled the IPB from 9/86 on and find that 13631710559 is the only TPS used on a 325i/is.

Thanks Jim

FYI for those who might come about this,

The 599 is BMW's OE number for the 321 Bosch TPS...

Just in case someone else comes across this in the future and is a part number nerd like myself...

Gonna bump this and ask if it matters if the tps is from a automatic car and I'm trying to use it on a manual trans? I was just asking because I noticed on rockauto comparing prices it says auto trans and maanual trans and also my tps is from a auto 325is. Could be why my car is actimg funmy when i rev it up.Does it matter?

[jlevie]

Only one TPS is used on M20 engines, regardless of the transmission.

Alright cool thanks for the fast asnwer

A lil bump action. Difference between the E (13621273277) and I (13631710559) tps... assuming one is smaller than the other based on the throttle size difference of each motor?

[Swanny]

Anyone have both for a side to side comparison as well as some resistance measurements?

[nando]

there's no resistance. it's a switch.

[Swanny]

Sorry, bad wording. That they have the same operation from idle to WOT carried over the same pins.
