zinkawe Z Hi all I have an issue with 2007 bmw e90 n46 2.0 idle poor and stalling When cold one of 7 time it starts And Its throwing these codes 2A61 Valvetronic adaptation 2A67 Valvetronic internal fault (does internal means vvt internal or dme internal) Aloso is there ecu specified for the vvt or its integrated in tge main DME? Ok, so i was sure there was something wrong with vvt. So i decided to change it since it couldn't be re learned in that case So i took it out and just for curasity i tried to connect it to external 12v source and then was the surprise It turned just fine to both directions!!!! I put it back in place and tried to do relearn to its stops with no luck of it moving I checked the voltage of its plug and there was about 4.5v when igbition 2 Checked the its fuse and relay both looking fine Checked the wiring, all fine Is there any chance that the Eccentric shaft sensor gone bad without throwing codes and it affects the vvt beside i found oil in the sensor plug? Couldn't find any datasheet fot the sensor Or could it be the DME Any advice Any help would be much appreciated #1 · Jul 16, 2017 (Edited) Hi all I have an issue with 2007 bmw e90 n46 2.0 idle poor and stalling When cold one of 7 time it starts And Its throwing these codes 2A61 Valvetronic adaptation 2A67 Valvetronic internal fault (does internal means vvt internal or dme internal) Aloso is there ecu specified for the vvt or its integrated in tge main DME?

My ESS threw a few codes for it. The vvt motor only threw a vvt motor sluggish movement code wen it went and I had dealer do relearn. #3 · Jul 17, 2017 Thanks Steve for replying Did you tried to connect it to external 12v power source? 0 Reply Insert Quotes Post Reply
