This multi-function is used for various function in different models such as heated rear window, circuit 15R1, Circuit 87 motoronic, manual transmission pump, secondary air injection pump, fan oil cooler, and pneumatic suspension. Relay 002 542 72 19. Remove the relay and jump terminals 30 and 87 together, if the pump runs, replace the relay. Though this noise should not be loud. I have 2010 C300 4Matic Sport I got error code P0410 I checked secondary air pump with separate power supply, it runs I changed 40 ohm fuse, that was blown out Replaced relay P. If I send power to the pump directly from the battery or test light, then the pump will turn on and raise the car up. September 1, 2018 Followup from the Pelican Staff: if the fuse was blown, either the wiring after the fuse to the pump or the pump is shorted.
Start the engine, it should be cold. Do not have missing parts, hardware or instructions. It was not attached to the box at all which is odd. But this last time everything seemed to work and still had p0410 coming back. Figure 11 Secondary air pump check valve solenoid testing: Next, remove the vacuum hose from one of the check valves.
A002 542 1319 Testing the pump is straight forward, lift up and off the front section of the plastic engine cover and remove the air pump power connector, apply 12v to the exposed contacts from an external source and listen to the sound the pump makes — if any. Manual transmission pump, secondary air injection pump, and fan oil cooler. This item can be shipped worldwide. Never had a problem with that on other cars so never even knew to check it. Go to top of page. Relays in this circuit as well as ones in the Air-matic circuit should, in my view, be changed as a service item every 50k or so miles to attempt to prevent costly pump repairs. 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.
Once erased you will need to cycle the ignition for this fault to fully clear. These airmatic problems have been driving me crazy. Are in the original packaging. I have no fault code i obd. If not, check if the vacuum hose is broken between the solenoid and intake manifold.
This is a common Mercedes problem. So I know I have an airmatic system. A job that would have cost in the region of £1000 with not much change, if it were to have been done at a Mercedes dealer. Unfortunately, sometimes human error and product failures do occur. Could it be a relay, if so which one? The front two are shown red arrows. I checked fuse and relay.
Even Mercedes service information is not this informative and put down in such a matter of fact, understandable way. Qualification for membership is for owners of such cars and true enthusiasm for the marque. I am having problems with my airmatic pump, for some reason there is no power being sent to it. Note — fault light cleared in this picture. Print up all the wiring diagrams say. Mercedes Benz 220 327 0930. It only has vacuum when the secondary air system is activated.
Once the engine is warm, air injection is halted. For Mercedes Benz C-Class C180, C200, C230, C240, C280, C320 — 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008 model year, 203 chassis. Burned out rotor of the air pump, probably due to overheating. This relay is used for different functions such as heated rear window, circuit 15R1, circuit 87 motronic. There may be a slight exhaust pulse noise. 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. Found that orange maxi fuse blown.
Check if the pump is full of water. It is worth checking the vacuum actuation components and piping with the pump motor housing removed, any hoses that are split or look bad should be replaced. Story I heard was that the early pumps wear out trying to keep the early struts full. I know i have a slow leak from the rear bags but before i invest heavily in new suspension parts i need to see the compressor work. Once the silver contact area of the relay has deteriorated unreliable operation will result. Are in the original packaging.
You can also isolate each valve by only applying vacuum to a specific valve and listening for the exhaust pulses. Thanks for both your help. Purchase, download and print your own copy for use in the workshop or just simply if you prefer to read all the content off line. It should sound like a vacuum cleaner motor as it spins at a very high rate, if it sounds like its arcing or rough running its probably at end of life. Malcolm refers to a slot on the main board, which i do not have. When a cold engine is started, the secondary air pump will run for a calculated amount of time. Can anyone tell me where it lives? This relay is used for various functions in different models such as heated rear window, circuit 15R1, Circuit 87 Motronic, manual transmission pump, secondary air injection pump, pneumatic suspension, and fan oil cooler, Pneumatic suspension, and secondary air injection pump.
