For the Injector drain hose-

@hangit

So when I check the "fitment" of this hose by this suppliers website and I check it on E-bay for the same thing via their fitment guide, both say that this hose is NOT compatible with the 2006 E320 CDI. But this almost has to be the right hose, as the original is definitely 7mm OD Contitech cloth covered hose. How many of this type of hose can there possibly be? Comments?

That hose at RM will do the trick and probably get to you faster.

orings are easy to get- you can look at a well-stocked hardware store or order online. There are online resources for material compatiblity with fuels. I think NBR is common and good. Mcmaster-carr will have them if you can tag onto an order cheaply.

Please list your resource that you find and the size/part number.

Glad you go the gasket installed....

Thanks!

the 3.2mm 1/8" hose is what I used. Fits fine and the car is running perfectly.

I'm sure that Buna-N (NBR) will be appropriate. I'll take one of the existing o-rings to my local seal house and get it sized up and post the standard metric o-ring size number. For the record, I would not source o-rings from a local hardware. Quality levels of Buna-N seals varies all over the map as there are different material versions/durometers of Buna-N and getting them from a seal house is a much better bet. M-C should be an OK source. These are probably $.03 o-rings.

I've got a problem with the car that isn't on my original list. Now that it's getting warmer again and I had a 4 hour drive today, I was reminded today.

What happens is that on more humid days, the A/C stops putting out cold air. I can turn the fan on maximum and very little air flows out of the vents and the car gets warmer and warmer inside. If I stop and turn off the car for 10-15 minutes and get back in, then it works fine again for another hour or so, then I repeat and it's working again. (I've had this occur on other cars as well on longer trips.) It's as if the evaporator coil is icing over blocking air flow and when I stop, it melts off and then will work fine until it ices over again. That's my best guess anyway. It gets very humid here in Ohio and today was humid.

Anyone have this issue? What's the cure? Clear a blocked drain hole? Vacuum dirt off the evaporator? Or is my diagnosis incorrect?

EDIT - I called the dealership and then did a search here and found a service bulletin about how humidity sensors were omitted from vehicles starting in 2006. I checked and sure enough, mine was omitted. So this could be the problem indeed! I bought a used sensor off of Fleabay for $10. Now just to get it recoded for the sensor as present. Hopefully that works!

Why didn't you take it to the dealer for the humidity sensor since it was a service bulletin? It should have been a covered item and service.

The evaporator coil is icing over. Your system is low on Freon. Get it properly charged and that will take care of your problems. My cdi did the same thing and I added a can of Freon. Members from this forum frowned on that because I did not fill it exactly to factory specifications, but at the time my cdi was 10 years old and I took full responsibility if I screwed up. It is working now and does not freeze up.
