Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi, sorry for the long wait on this question. I have been away a lot over the holidays. You should be able to reset the self adaptions on the Autel. Even if you don't reset them they should eventually come down to normal range after driving the car about 20 miles or so. Your fault codes and adaptions indicate a fault with the fuel mixture on both sides of the engine (too lean) at idle. If the MAF sensor was the problem your adaptions should have come down to around 0. It looks to me like you still have a vacuum leak. Since both banks are affected I would look for a leak at the MAF connection to the intake. Ideally you should smoke test the intake system to locate the leak. If the car runs well I don't think you have a fuel pump problem but a fuel pressure test should be performed if you find no vacuum leaks. The aftermarket MAF sensors can also be problematic. If there are no intake leaks and the fuel pressure is good I would try an OEM MAF sensor. Also, if the pump were the problem your adaptions at partial load would also be high. Your part load looks good.
Let me know if you have any questions.
You're welcome, Alex. I'm leaning more towards an intake leak based on the adaptions.
It certainly appears that there is a vacuum leak. The brake booster could definitely cause this problem. If you suspect the booster you should disconnect and plug the booster vacuum line then see if your adaptions start to drop. Ideally you should smoke test the intake system and check the fuel pressure.
The picture is too close up. If that's a vacuum or breather hose it will definitely cause the problem.
I can't see the broken part in that picture. Take a picture with your finger pointing at the bad area.
Ok, take one more from pretty far away and place an arrow so I can get an idea of what I am looking at.
In your second picture, if the hose you are pointing at is the one that is split then that is your problem.
If it goes to that booster hose then it is your problem.
Just checking in. Did you ever get this problem resolved? Did you replace the booster hose?
Sounds like it's worth a try. Let me know how you make out. Please don't forget to rate my service in order for the website to credit me for helping you.
You're quite welcome.
If you can smoke test the intake system that would be best. You could also spray all around the intake with carb spray with the car idling and see if it picks up any vacuum leaks. It's not as good as a smoke test but you might find something.
Your problem is that the car is too lean at idle. If the EGR was open it would misfire and you would get EGR fault codes. You are just getting mixture codes at idle speed. A vacuum leak is the most likely cause.
Hi Alex, sorry for not replying sooner I did not see that you replied to me. The rotor adaption calibrates the crank sensor to the ring gear. You should be able to go into adaptions in the Autel and find the option to perform the adaption.
I agree with changing the fluids but I don't think it will help for this problem. I would suggest checking the transmission mount and motor mounts for this problem.
I thought you said it was rough at idle. Another possibility would be the ignition wires, coils and spark plugs. Bad wires or a bad coil or spark plugs can give you an uneven feel at idle.
The adaption is not mandatory. It just fine tunes the misfire detection capability of the ECU.
