Parts warranty
My new control unit comes with a 12-month warranty. However, I was told that, if the car had been, say 2 years and 10 months old, then a new control unit fitted at no cost to the owner, would automatically become part of the vehicle's standard U.K. 3-year warranty, i.e. it would only have a 2-month warranty.
The moral of this story is that if you pay for the repair yourself, you can have a full warranty, whereas if MB pay for the repair, you can't.
Is this true? If so, can someone please explain the logic to me.
