Most of them have the same setup. Apart from aiding to prolonging the life of the catalysts and meeting lower emissions targets the secondary air circuit does not effect the normal running of the vehicle if it is disabled in a particular way until a fix can be carried out. The relay i removed was from the loose slot that you have pointed out, so reading between the lines i may well have found the air pump relay, but i need to fit the correct part ref Malcolm's number.

Mercedes Benz M113 Engine S Class S500 I have recently taken delivery of a used S Class Mercedes, 2002 model W220. Mercedes S Class w220 — fuse box diagram. At the same time the electrical solenoid controlling the check valve vacuum is energised, allowing vacuum to pull open both diaphragm caps. But this last time everything seemed to work and still had p0410 coming back. It does this among other things by monitoring fuel trim and by identifying emissions changes then comparing its findings to an inbuilt reference map.
Support your free Mercedes Benz resource — Get the book! If even one of these control sections is giving issue, then its comparative live testing will result in a fail and flag the P0410 fault code. It will prevent any electrical current flowing to the secondary air pump and it will also prevent the air check valves on the exhaust manifolds opening with the possibility of allowing exhaust gasses to exit via the disabled air pumps delivery pipe.

This is the second of the review book series and each year around July a new review book will be published. Test cold start, listen for the pump to run and switch off anywhere between 45 and 90 seconds after start. In the vicinity of the black vacuum solenoid that diverts supply to the air check valves is a small blue plastic vacuum check valve, these have been known to stick and cause incorrect operation of the air injection check valves.
