Sorry to resurrect an old thread but running into this same problem on my S52 swap (3 hoses and 3 connectors on 6-cyl heater valve and 2 hoses with 2 connectors on 4 cyl valve). I'm assuming it has to do with the M3 climate control versus my manual heat and A/C controls in the Ti. What have people done with the extra hose coming off of the S52? Just cap it? |
