    So, I can't figure this out, maybe you guys can help.

    I have replaced my cooling fans 3 times now, 6 fans. Thank god for FCPEuro's lifetime warranty.

    My mom's GLI, same thing, but 4 times, 6 fans.

    Mine started out with a cooling fan code in my engine module. Hers have all been vibration failures. All of the replacements on mine have been vibration related. (4 vibrators)

    What the heck is going on? I'm torquing nuts to spec on all fans. None of the fans have had weights missing or chunks out of them. I don't push up against them when working under the hood on either car. I installed all very delicately making sure not to press on them when torquing the nuts. New radiator mounts on both cars, new engine mounts on both cars. When putting into service position, I torque all bolts to manufacturer spec. Resistance tests fine all all fans when replacing them. Both fan cowls look to be in great shape, no chunks out. I have cleaned both nuts and cowl surfaces all times thinking a slight kick could cause them to fail again. This has been a severe frustration...pardon me SEVERE!

    These have all been either Meyle or Behr units going in, no cheapo fans at all.

    WHAT GIVES?

    Please help with either helpful hints you've run into or theories as to what may be going wrong, I'm super pissed right now, I hate taking either bumper off.

    Thanks in advance.

    Since the first fan replacement, I haven't had any codes. Originally it was a fan module code, I think for the small fan V157. I'm not 100% on that number. But the modules are in the cooling fans. Since that first replacement, every single fan I've replaced has been simply because they were vibrating horrendously. They'll stay quiet for awhile, but maybe a week or two after replacement start vibrating again.

    Hmm, so this vehicle does not have a second Coolant Fan Control Module. Just J293 controlling electrical components V7 Coolant Fan and V177 Coolant Fan 2. The code from vcds: 18359/P1951/006481 - Radiator Fan 2 (V177): Movement Restricted / Jammed. It was either that or the 18358 for the V7, I can't remember and just replaced both when it came up, because I figured the other would go shortly after that.
