Engine Bolt Recall

BY the goodest grace of their godly german hearts BMW says they will recall 156,000 vehicles, voluntarily. 3, 5 and Z4 from 2010-2012. Its one of the bolts relevant to VANOS, some cars its all cool, some are loose and some will shear. So you can keep driving, but the minute you get a check engine you'll know why... bimmer on a hook, never fun...

It's not the worst thing that could happen. It likely means the bolts are vibrating themselves loose. I don't see it as a HUGE issue. And it was voluntary. I wonder if it had to do with service protocol, perhaps checking those bolts was left of the check sheet or something along those lines...

Likely, It's very possible it's something techs came across with some inspection or service job that included a bunch of little maintenance things.

VVTs are giving everyone headaches these days. VVT is so dependant on clean oil pressure to move the phasers for advancing and retarding cam timing that they are highly susceptible to gumming.

Mind you there is no tangible problem with the VANOS system operating, simply a bolt...

What is the danger of this bolt loosening? I didn't read anything about what the fallout from the bolt loosening would be.

I don't hear about BMW recalls very often but I think this could be part of what some people have been saying is a overzealous wave of of recalls. A better safe than sorry kind of mentality.

No idea, but the main thing is if you see a check engine light, take it seriously.
