E63S with Enginelight P209900
Hi everyone,
The service engine light recently came on with my E63S 2014. I plugged in an OBD2 scanner and it came up with this code:
P209900
Post Catalyst Fuel Trim
System Too Rich Bank 2
Has anyone had this happen or does somebody know what could be wrong?
Thanks

Yes I got an Stage 2.
The car had catless downpipes.
I removed them an installed the oem cats two month ago.
Could it be also an exhaust leak?
I'm just afraid to get some engineissues.

Entirely likely exhaust leak with your setup... not sure how it will affect engine -- is the CEL blinking or solid? Did you use the old sensors?

But can a exhaust leak be the reason for the cel / errorcode?
I erased the engine light with xentry.
Drove 15mls yet and it didn't came up yet.
Yes the old Sensors are still installed.
Can it be monitored if the engine is running too rich?

I logged Bank 2 and I saw that the intakecamshaft numbers are Red.
Also logged the long term Fuel Trim and noticed Bank 2 is always more than Bank 1

I still got the problem.
Some days ago i changed the camshaft sensors because i had the famous problem with oil in the ecu harness.
So maybe the error won't come again.
My next step would be to Check the exhaust for leaks.
Please let me know if you solve it.

hi @munich55 did you figure out your p2099 code? I just got that one showing pending. Car seems to be driving fine. I’m tuned with intakes only. Did the cam sensors a few months back.
Wonder if the issue I have is perhaps related to the air intake sensor connectors since I have an aftermarket air intake system with extensions on the connectors. They are about 3 years old now and not sure if for some reason they go bad.
I just did a full spark plug and coil change at 49k miles (am tuned 93 octane, intakes, nothing else) and the car was running perfect for about 2 months and this P2099 just came up.

To clear permanent codes you need to first fix the problem. Next you need to do a drive cycle with the problem fixed. That pretty much just means drive it for 10 minutes fully warmed up. You will be able to reset the code at that point IF the problem is actually resolved.

Thx I should have specific was asking about that particular code P2099 and for those who had it was it related to the intake sensor or sensor connector starting to fail or something else like the O2 sensor most likely?
I’ve had this come up 2 times prior in the last 3 years and after clearing the code and doing a few drive cycles it went away but not this time so I assume it’s intake related but looking for input from others who’ve experienced the issue.

Old thread,
i had this same issue.couldn’t find much online about resolving this.
having a discussion with the AMG techs here in New Zealand - they advised to do the following:
1. Fill up with the car with the highest octane available at a different gas station. Clear code and if it pops back up proceed to next steps.
2. Remove bank 2: (Drivers side here in New Zealand), Sensor which is located on the CAT itself. Check to ensure this is firstly tight incase it’s exposed to outside air - Remove and clean the sensor. Once replaced, clear code & see if this does the trick. If not, proceed to step 3.
3. Replace Downstream Sensor.
some other things to look out for is during your initial diagnostic, check the voltage of both sensors and check to ensure the voltage is identical. It’s highly unlikely that this issue is due to a faulty sensor - although I have read about people having issues with them. Plug in the scanner and check the fuel rail pressure. Don't start the car but set the car to the second start position. You should see one of the rails losing pressure in the instance that theres a leak.
