You are correct. There was no difference...but I was going in for an alignment anyway (they sent a coupon!) and wanted them to double check while I was there. The replacement part had not arrived yet so it was nothing lost for me to ask them for a confirmation.

Anyone?

P3 gauge starting giving this two days ago.

SEI · 07-27-2015, 09:50 AM

anyone know what p138b is? cant find it

pbonsalb · 08-24-2015, 06:33 AM

Anyone know what the fix is for a P155D code? It is part of the 2B26 family. I know what the code says -- it is listed in the code list in the forum here:

http://www.m3post.com/forums/showpos...0&postcount=44

What I can't figure out is what is the fix? It is not the actuator. I swapped in a Hall sensor and that did not do it either. I am curious about the Hall sensor clutch, which looks worn and loose.

Do you know what 2727 and 27C7 is??

elm3 · 12-01-2015, 12:32 PM

What about code 2B65?

kiln · 12-24-2015, 02:05 PM

Can Regular Guy still be contacted outside of this forum to get a fault description?

Left-side throttle actuator, according to Google:
http://www.m5board.com/vbulletin/e60...de-0x27a2.html

Per the thread, it may not be the actual actuator, just the wiring.

Tony I've had 27A1 twice this week. Replaced the Hall sensor (aka throttle sensor - the one on the end of the row of throttle bodies). Will report back and let you know if I throw the code anymore and go back into limp mode. Hoping to avoid the $900 throttle actuator

m3nace92 · 07-05-2016, 09:40 AM

Any idea what Cdb6 is? It was mentioned earlier in this thread but nothing was really expanded upon with it and I haven't been able to find info anywhere else on it. What fixes/solutions/labor to take care of it mainly?

Thanks in advance
