My AC has been smelling worse and worse over the past two years and I recently injected Klima cleaner foam up the drain tube (2 cans).
The smell still comes and goes and what was more concerning was that not a lot of cleaner came back down the drain tube. Two whole cans used, about 1/10th of a can came out..... Bizarre
I'd like to get access to the evap coil and spray it on directly, does any one know the location of it and if there's anyway to get direct access via a can with a sprayer wand?
The evaporator is completely enclosed within the heating/AC plenum and not directly accessible without a lot of disassembly. However, you could try injecting the cleaner/disinfectant directly into the drain port nipple (after removing the hose).

Thanks, Yea I know that the evap is fully encased and this is exactly what I did. Used two bottles of Klima cleaner and it didn't really work to my expectations. Two bottles in, only a few ounces came back out, weird. Now I'm asking for the evap location for more aggressive reasons.
The general idea is to get as close to the evap as possible and some people have a better time doing that by taking the blower motor out in some cars and the evap could be "right there" or close enough for a hose.
Other guys on Bimmer forums drill a hole in their plastic and insert the hose through there because their schematics show the evap is almost impossible to get to.
I'm looking to get info on where the evap is on the nx200 so I can figure out my personal plan of action.
The blower motor duct connects to the housing along the lower right side.
Thanks! I don't really know what to make of that tbh. With the glove box out and the blower out, would the evap be towards the left via the newly accessible vent?
See if this version helps to visualize where the evaporator (item 10) is located within the HVAC assembly.
I do not think item 9 (supplementary electric heater) is offered within the USA market.

That's great. Thank you for sending.
From what I can see, going through the blower motor may be good. Hard to tell what twists and turns lie in the ducting
