Reading Codes

[billyrohm]

So I tried to read my code tonight (2007 MS3) and I keep getting a link error. I had the key in the on position and running and still link error. I read my other car and the reader worked fine. Does the MS3 need a special reader or could there be something else wrong?

What reader are you using? It must be capable of reading OBDII CAN data format.

actron cp9135

I guess it cant read the Can data format, is that new?

Yep, all new cars are now OBSII CAN data...
I think it started in 2004-2005???

Went to Autozone, they had the same reader as I have and it worked, p2187sweet. Mine must be messed up, I dont know though, it worked on my other car. I'll try it again tonight.

So whats a p2187...? Why is it a "sweet" code? (huh)

I too am getting a P2187 lean at idle code. Dealer did a PCM reflash for this issue. They state there is a new TSB released just last week for this issue.

 

[AutoXRacer]

Is the reflash going to make the tune richer than it already is?

I think he means, it is good to decipher the code. Are there any codes that are sweet? Like; barometric pressure is just right for my afr , run me hard today. Or Temps are correct for massive burnouts..
