P1515 error code

[BJoe]

Hi,

A few months ago the SES light of my 2003 z4 2.5 came on. I went to O'Reilly Auto Parts to have a quick scan and the code P1515 showed up. They could not tell me the meaning of that code, because the scanner (INNOVA 3120LaT) displayed "The Manufacturer specific Definition is not available"

I really don't know, but after looking at several forums (for instance, http://www.z4-forum.com/forum/viewtopic.php?f=3&t=23628), the problem seems to be related to the "Throttle Position Sensor (TPS)". Although, the car feels ok, I haven't noticed anything strange but the SES light (It goes off for a few days and then it goes on for another few days and so on).

Have you seen this error code before? Your experience and comments would be of great help.

BTW, I couldn't find any DIY video/instructions related to the TPS. Do you know how to get access to it?

Hope to hear from you soon!
Joe

Any ideas?

So far, the car is working fine ..... However, having that ligth on is kind of disturbing!! My mind is like what's going on? What's going on!
