E83 X3 with 2A80 VANOS activation
I own a 2008 X3 with 126,000 miles. Recently it gave the 2A82 and 2A87 codes which were cleared and returned. I purchased two new VANOS solenoids on Amazon and had my mechanic replace those. He did try and relearn the system, which I didn't believe was necessary for this repair, but I now have a "2A80 Intake VANOS activation" code which cannot be erased with my C110 scanner. The car idles rough on startup then drives but with reduced power.
I cannot really pinpoint the 2A80 fault as it is not prevalent on the forums. I also have the triad and had him replace the actuator gear, but the fluid wear code is on and the lights won't go off. I know I need to replace the fluid and maybe clear that with some of the software available...? Any help is appreciated. |

He's not using ISTA+. That's the problem. He should calibrate the clutch packs (aka reset the oil wear light) when changing the transfer case fluid....too bad many skip this/don't even care. You'll need to run diagnostics with ISTA+ for those codes. There are plenty of threads on downloading/setting up ISTA+, so set it up first, along with BMW Standard tools. Then buy a K+DCAN cable (bimmergeeks or similar).
As for how diagnosis works, it's a dealer software, so when there are codes present (you first do an auto-scan), it will see those codes and come up with a test plan...basically ISTA+ tells you what to do. |

Thanks! I was thinking of getting that to reset the transfer case fluid.
But on the 2A80 code and the reduced power...? I cannot find any definitive information pointing to a cause. Maybe the off-brand VANOS solenoids, the inlet solenoid didn't get plugged in properly, etc. ? |
