    As some of you know I like stripping things down see how they work and what it looks like in side and some times I post em up.

    Yesterday I helped my dad fit a new stepper motor to his Touareg cause the old was fault and causing his drive train to clunk and pump going around bends when bumps.

    Easy enough to do, just 5 bolts, 2 plugs and out it comes.

    The strip is really easy as well, 3 torx bolts and it lifts apart.

    Top cover removed showing the motor.

    Pulled the motor/coil out and you see the brushes. Its not very shiny, so assuming that's our issues for this one being faulty.

    End of the motor.

    In side is a set of planetary gears.

    And another set.

    And a third.

    That's it. its very basic.
    I expected a lot more from something that's worth almost £500 and controls the centre diff lock.
    O well.

    That's the inside of a stepper motor or servo motor or gear box motor depending on what you read.
