Ok,... I just found some added history to my C32 thru more discovered service records. Most of them I can understand, but this one I'd like to get some comments on. Specifically, I'm wondering if some of the intercooler and S/C problems everyone has been talking has been address. Here is the service description in it's entirety:

SERVICE CAMPAIGN 2006030011
MODEL 170/199/203/211/215/219/220/230/463 AMG
MODEL YEAR 2002-2006
REPLACED SECONDARY AIR INJECTION PUMP RELAY
DC 59 950 01 7
FW PERFORMED CAMPAIGN 2006030011 COMPLETED REPLACEMENT OF RELAY AND PERFORM ME UPDATING PROGRAMING
FP-NUMBER 002-542-26-19-64

Sound pretty cryptic to me, but I'm trying to get a fix as to how much of the most talked about problems with the C32's have already been address by the previous owner. Reading anything about 'air injection', 'cooling' or 'control modules' peaks my interest.

Thanks

PS: I thought it was interesting to see how they list the 'model year' as 2002 thru 2006.

It should answer all your questions.

99.99% of them,... Thanks man!

You are welcome. By the way, when the dealer did this campaign on my car, it started to shake at idle.

hi dude - did you ever get the shaking at idle fixed cause mine does that and no dealership ive been to (and its now 6) have felt it was a problem - they all said its normal! rubbish I say - just wondering if youd got it fixed at all?

Well I don't get a shake, and apparently it was done (previous owner), but I'm now noticing that the boost from the S/C IS NOT always at my disposal. On certain occasions, when I get into the throttle, it's like driving a C320 or worse,... like one of those 2.4 L plants. That's becoming a concern.

I have an appointment with the MB dealer today. Now that I'm positive I have warranty left, I plan on exploiting the coverage. Started on a list last nite! I'm wondering if I can get my Valeo radiator swapped out under warranty? So far I've got the seat controls working in reverse, the constant battery drain, and now,.... this S/C concern.

Thanks guys!

Lost power, on random occasions after driving for awhile is typically the IC pump for the supercharger air charge cooling circuit. Drive it hard for awhile, after it looses power so it will set the high IAT limit set code in the ECU.

Huh???? (LOL)

Ok,... If I'm understanding you, your telling me to force it to set the air temp limit higher than it is so that the S/C stays active longer as the temp rises? Sorta like replacing a 15 amp fuse with a 30 amper to keep the circuit from tripping so frequently? If you say yes to the anaology,... then I kinda got it! If you say 'NO', then it's confirmed,... I'm lost!

In a word, NO. My car will shake, occasionally, when sitting a stop light or such. It is faint and, yes, the dealer was never able to detect any abnormality. I just live with it and chuckle to myself when it does it. The dealers love to say, "it's normal". They say the same thing about the tranny jerk.

No, the reason for running it hard into the supercharger cutoff, is to get the ECU to set the error code for IAT too high. It is the only code error related to the pump failure, that the MB tech will see.

If it does not set the code, then the tech could waste days trying to figure out what is the cause, because, they will say "ooh, we have never seen the IC pump for the supercharger fail". Typical BS.

OIC,... gotcha!

Well like I said, I had a 3:00 service appointment today. There was someone on it for at least 2 hours straight. (I like the way they assign a technician to you.) Anyway,... after they disconnected the diagnostic wires and computers, they began pulling things apart. I watched them take the shroud off but I had to leave. They gave me a ride home in one of their G class shuttles and agreed to pick me up when the repairs are done. It's still there. They told me they were addressing a suspected problem with the Super Charger and would be replacing some Control Modules. That's all I could get out of them. When I asked of a projected cost to me,... they said it would be covered under warranty but promised to call if an uncovered problem was discovered.

I will describe in as much detail as possible what they did and what affect it should and does have when I pick my car up. But be patient with me,... I'm very new at this and don't know all the jargon!

JustmChecking in to see what you have found out?
Thanks

Well got my car back from the dealer a day ago (2nd service visit) and the Super Charger/Inter Cooler problem still exists. A fellow board member made a few suggestions, so I have another appointment tomorrow morning. To be honest,... at this point I have no idea what they're going to do. I just want my Super Charger at my disposal WHENEVER I ask for it. I have learned that there is one exception to that rule/expectation. The system is designed not to allow the Super Charger clutch to engage over 3,000 rpms. I've been told that for that safe gaurd to kick in, you'd have to be cruising at around 80, then engage full throttle,.... I can live with that! I think!

Anyway, I gotta be there at 7:30 a.m. and do some extended driving with the tech. In a sick kind of way, I'm hoping the Super Charger itself is shot. They've already replaced the clutch, serp belt, pully and I/C pump,... and it's still going AWOL when it wants.
