My 99 E320 has developed a problem my repair shop is strugging with.
An alcohol or coolant type smell enters the cabin when the ventilation is
turned on. No coolant leak was identified with pressure testing.
Your heat exchanger has a leak and if it is not covered by warranty, the
labor is very expensive. The entire dashboard must be removed,m etc. I would
only have a dealer fix it if covered, otherwise go elsewhere. P.
