I got this cable from eBay:
http://www.ebay.com/itm/BMW-Inpa-K-C...24963514720151
Installed INPA / NCSExpert as per beginners DIY and am running into intermitten IFH-0003 data transmission errors.
The car is a 6/2008 built 135i.
I've Google'd up and down the Internet and can't find a solution.
Latency is 1, FiFo's are enabled, used the tool to put cable in D-CAN mode etc. etc. Still the same. 2 black dots in INPA, NCSExpert can read the VIN etc. but as soon as I try to read the CAS module for example, I end up with IFH-0003 after a while.
Any ideas?
