Does anyone have any info on this? I searched all over the internets and I couldnt find this. The closest was P20D4 Load limit code.

I messaged a contact at a MB dealership and he told me that its related to the intake. His reply: "Easiest and most common to start is replace intake gaskets and bolts. There is partial load breather hose on the back that is done a lot of the time when doing the intake. It takes some testing to see if it is the problem. Slight change that it's the intake itself but not that common."

No CEL, but this was a stored code from the last 1.5 months since after I bought the car, when the codes were cleared. Should I be worried about this? I don't want to do any unnecessary shop work.

That's the only google result that matches P1061 but I don't think that's the right one.

 

Ok

 

I know you're trying to help make us young bloods more independent but trust me I've searched everywhere. I wouldn't be making this thread if I wasn't out of options.

 

MAF

 

Many OBDII codes are universal, not sure if this one is MB-specific or not.

If its the MAF then that's great news. I did replace my air filters and maybe dinged the sensor. Thanks for the input guys. Going to check this out later.

 

Don't sweat it, just clear it and move on. See if it comes back. Don't start pulling airboxes off, MAFs out etc or then you can start having issues where none really existed before.

 

I think this is what I'm going to do. Car drives fine and I'm in my first two months of ownership so I'm paranoid about every little sound and problem.

 

I've had 3 of these over 6 years and I can still be a little paranoid. Reality is that, just like us, some days are cars are just happier and run better, and some days.......they ain't. This is especially true with anything computer related, and like all computer based stuff they can sometimes use a reboot.

Seen a ton of issues that go away with a sit over night, or a half an hour park and a reset,
or a battery disconnect.

 

This is very true. I call this the "Bill Gates method"

 

Subbed for updates and future reference.

If it doesn't come back, or if you solve it by replacing the MAF, please report back

Interesting that if you search for "Mercedes Load Limit", there are a number of threads - including this one :

https://mbworld.org/forums/w211-amg/...lash-done.html

Seems that this is a code that's thrown when either the engine or the gearbox go beyond the designed load. Lots of speculation that it's a "telltale" for a remapped car.

 

I'd be okay with this, as long as I'm not wearing out the car too much faster! Good to know. Hopefully this is the case haha.

If this is indeed the case then shouldn't everyone with a tune who pushed the car hard have this stored code?

 

What filters did you swap in place of the OEM? If dry filters then ignore this but if you put in K&N that may be the culprit as our MAFs are very, very, VERY sensitive to anything outside of their comfort zone and the K&Ns may have covered one, or both, of the MAF elements with a film of oil which is sending them into a frenzy.

 

Yes it was KN filters! Hmm

 

God I can't believe I've only just came across this relpy.....
I've sat for hours online trying to diagnose the P1061 code.

2009 Merc C280 3.0 V6 W204 having idle problems with high revving while in drive & stationery, When depressing the accelerator just a tiny tiny amount the revs run up to 2500rpm hold for 3-5secs then reduce to 900rpm idle. Some other times idle is 1200rpm (after warm up) & car revs itself from this to 3000rpm then back to 1200rpm idle repeatedly.

3 weeks prior to having this problem I changed out the OEM air filters during service for two K&N filters, I noticed oil residue on the rubber seals & did think this was strange & that it may be pulled into the engine through the intake, but fitted them & wiped the excess oil off.

I've had the MAF removed cleaned it using Liquid Molly MAF cleaner, No difference, this morning the new MAF arrived fitted it, cleared code, run the car & nope its back again.......soooooo guess what i'll be trying tomorrow.... anyone want some K&N filters .

Thanks for your help. I'll let you know how I get on with this
