Hi I am posting here to see if I can get any help.


So on my 2011 GL350, I have a lot of little issues that I am trying to deal with.
1. Check Engine light caused my 13AF00 confirmed with iCarSoft MBII .. OBD error code P2463.
2. Steering rack bushings are shot and steering rack may be leaking.
3. I got an oil leak somewhere.. I replaced the oil cooler seals before. But that was like 70K miles ago.
4. Had the transmission oil changed .. got a code 2783. I am concerned that they didn't put enuff fluid in it.

So starting off with my first major issue. The check engine light is on I replaced the sensor a while ago.. using OBD fusion I was able to check that I am getting 10-30kPA reading for DPF differential pressure... http://www.enginesens.com/Delta-P_60...nstruction.pdf that does seem like a lot. But it seems that if I clear the code. The code is pending immediately. It makes me think maybe another sensor is also bad? Or are those values bad? Is the sensor bad? The one I took out was A007-153-61-28 and replaced with an A642-905-01-00 which I believe is ok.. I am kind of wondering one of the other sensors is bad? The exhaust temp sensors seem to be working I get values for both.

I had the DPF baked for 12 hours .. But I didn't chemical cleaned.. I wonder if it is really still clogged? I am thinking of getting the Liqui Moly cleaner and flush. I really like to get the check engine light off so I can see if the system with start doing its own regen cycle or altow me to do one at the moment I Can't even force one with the MB2 Carsoft..
Here are things I done so far with truck
1. Replaced air filters
2. Replaced Cabin filter
3. Replaced broken air intake tube (that piece was expensive) that feeds both air filter boxes it was cracked..
4. Had transmission oil changed
5. Replaced Diesel Fuel Tiler
6. Had DPF baked and blown out.
7. Blew out DPF sensor lines to make sure they were clear of obstruction. (they were fine)

Any recommendations ?

Not on my ML350 but on my 2006 Chevy 2500HD diesel the check engine light came on. I disconnected the negative side of both batteries for about 45 minutes. The check engine light went off and has not come on since. It may be worth a try on your GL. Good luck.
