Hi guys, i've just changed TSS and cleaned IAC, i have 1 question about TSS part number.

I've read in forums that new TSS should be 1S7Z-7M101-KA, i got that one(bag had this number) and new TSS had a different number(XS7P-7M101-AB), old TSS had almost same number(XS7P-7M101-AA), bolts were same and TSS itself were both identical made of white plastic .

I want to know if this is correct and both part numbers should be same or if car already had new TSS and i shouldn't have changed TSS.

Any input would be appreciated.

Thanks in advance
Delio

The 2000 should have come from the factory with the updated TSS.

You're fine.

Well, i shouldn't have changed TSS then. by the way i didn't notice any gain in new TSS, it just got better IDLE with a clean IAC
