I need some help guys, I tried and search thr the site but nothing came up about my problem? make the long story short another problem with the C32. On my way back from sf yesterday my CEL went on, I went straight to my friends shop run a OBDII tester. It says secondary Air injection pump maulfunction, I read coupe of the topics on the board, but nothing about how to change or install the SEC AIR pump? My Qs is, is it a big job? do i need to change some kind of relay? I read something about ppl have to change their relay& air pump. Any advise or help would be greatly appreciated * I just changed out my IC pump last weekend and now another air pump or relay OMG i thought my 2001 C320 was bad.

On the OBD II tester says Sec air injection system P0410, Does anyone know what's the part number for the AIR PUMP & RELAY possibly price
Thanks for looking -

Check and make sure the hose is attached properly first. I had the same code recently (P0410) and it turned out that the hose became disconnected.

do you know where is it located ? sorry when it comes with BENZ i dont know where anything is at * I notice the TEMP is going up when i'm dead stop in traffic !!! its almost around 97-98ish... Does this air pump has anything to do with it ?

thanks for the Pm , I found a thread about the part number, but noone has a thread about replacing the DAMM SEC AIR PUMP AND RELAY !!! I can see the pump should be easy to replace i think, but where the hell is the RELAY LOCATED ?

Hey Mate,

I assume u have a cf32, not a c320 ? If u have a C32, especially a 2002, then the air relay is in fact a product recall, when did u last get it serviced by mercedes ?? should have picked this up. The only bad news is though, when you change the air relay is does cause the IC pump to malfunction and pack up, now if you just changed the IC pump, b4 the air relay, then u gonna have problems, cos they are linked, and it is most likely shortly after fitting the air relay the IC pump will pack in again, irrespective whether its new or not ! I am picking my car car up from mercedes tomorrow in fact, just had the air relay replaced via the product recall, and following a test drive the IC pump has required replacing as well.

Because you have fitted the IC pump, it has thrown out the air relay, its best to stick to main dealers with these AMG's, cos working via independant garages and DIY, just cause these problems, and cause just more expense than a main dealer in the first place, to be honest main dealers are usually quite fair and more cost effective in the long term !!

Mercedes know that the Air Relay need replacing (hence product recall) and they know to do the recall first, then the IC pump.
Search this forum in detail, you will find details on the product recall, inc chassis codes and also details on the IC pump.

You may have to search a little, though, as this is an old problem, back 2 years ago, and these are now old car's, so its not something people are discussing on this forum today!

This is an Emissions problem which carries a 8 year 80k mile warranty. If you are under the 80k miles you might want to just have the dealer do it for free. Other wise start by replacing the relay.

This is correct. I recently went thru this when my S/C would go AWOL on me. They replaced my Air Injection Pump as a warranty (recall),... never did fix the problem. I took it back and then they replaced pullies and clutchs,... still no fix. The third visit they finally replaced the I/C pump,... which after reading many threads in here, I suspect was the root of the problem in the first place. The tech told me that for my model year replacing one dictates replacing other parts as well, the I/C pump prolly is one of these. They also replace two control modules,... not sure of their function thoo! Be blames my many visits on how the procedures were written to deal with the issue. In the end, he confirmed c32AMGUK's comment,... replace one and you gotta replace other stuff in the loop.
