Hey, guys; My 32 is throwing a B1416 code, which is classified as "Hot water coolant circulation pump." Is this the intercooler pump? The pump was just replaced a couple of months ago! Does this mean that it's dying? I haven't really had a problem with the SC disengaging, but I have been having some hesitation/roughness problems the past couple of months.
B1416 - Intercooler Pump?

It is the weekend for christ sake and a Mothers day weeked to boot. Linh, for a person who sold his SLK 230 years ago and never did own a 32 I find it funny how you come on here for time to time and it seems just try and pick fights. Is life so booring in Lake Elsinore that you feel compelled to keep coming back. It reminds me of life in the Navy. Once in a very rare while a crew member would transfer and for some strange reason keep coming back to visit. Seems they just could not let go. Let it go.
As far as the SLK32 why would most peeps even bother tuning it. The car was a rocket out of the gate and most owners prefer to keep the car as is. I figured after you were banned for 2 weeks and I think at one point were banned from MB World you would figured out that what information you have to share with others here, and you do have some good ideas, is vastly outweighed by your ego driven rants. Move on or at least buy "Another used MB" and get with the program. Why do you feel so compelled to always go after Bruce and others here. Reminds me of a jilted girl friend who cannot give up the idea that its over. It seems you have the need to fight and have drama in your life. I am sure the CLK and CL forums can benifit from your expierences but you have reduced yourself to an almost comedic reputation. Move on!

Aah, ok, so at least it isn't the IC pump again!
I've cleared the code twice so far and it keeps coming back, so I would assume that it needs replacement. What would the failure of this pump affect? Is this a DIY type of repair?

Sorry Adam, there are enough people here that can answer your questions, but this was a rough weekend to ask as most here in the States were busy.
Glad that Bazzle in Oz has you covered.
It would appear that the heat recirculation pump has failed, but to say that it would come up as a code seems unusual.
All that pump does is pump water through the cabin heater to keep you warm without the engine running.

Unacceptable, Bruce; I expect a contingent of experts to be on call to answer any questions I have 
No, no problem at all. I just wanted to bump the post so that it didn't get buried. I actually posted the question from my phone while I was getting my own Mother's Day present wrapped

Actually, I think that pump is always running, not only in REST mode. I think it also help to keep the hot water flow constant, so that it doesn't vary with engine revs. Otherwise you have very little water-flow at idle. Or at least I know that on my 190E it was always running, haven't checked to see if it is the same on the SLK.

I'm not entirely sure that the pump runs 100% of the time the engine is running, could be though.
Like you I have a 190E, and the only time I noticed a failure of that pump is when the A/C fan would cut out. There is no separate fuse for that pump and the only symptom you might get is the failure of the fan control panel. The car was plenty warm even after long periods of idle.
If it runs all the time, it’s a wonderful bit of engineering. I pulled the old Bosch pump apart after I replaced it, and the machining is first class. My new pump now has an inline fuse to protect the system.
