Issue Overview
The affected vehicles may have been fitted with inadequate heat protection on the water pipe above the

exhaust system.

If this is the case, in the worst-case scenario, this can

lead to deformation and, as a result, to a leak in the

water pipe.

To prevent this, additional heat insulation must be retrofitted to the affected vehicles before delivery to the

customer.
