I have occasionally been getting -- and clearing -- this DTC 5 on socket 8 for several years now and I'm trying to decide whether it's worth buying a new blower motor for the module box. The manual states, "Maximum allowable temperature in module box (F23) exceeded." But there is a footnote to this that states, "Module box blower was phased out of production on model 140 starting M.Y. 1994."

What was Mercedes' rationale for discontinuing the blower? Did the E500/E420 after model year 1994 have a blower for cooling? Thoughts? Thanks guys.

It's an extremely common code that nearly all E500Es get. And as far as I'm concerned, it's nothing to worry about. I just reset it and ignore it when it appears.

Cheers,
Gerry

I'm good at disregarding, ignoring and resetting. Thanks.
