Typically that's e85r pricing. That's what I pay for a 5 gallon can of the stuff. I also have the option to buy e85 at the pump but the ethanol content isn't always as consistent, and they do winter blend here too.

Smell could be from a rich tune as well

Anyone fool the CEL with O2 simulators, I know people have.....asking for a friend

I dunno but now my car is getting P0060 and P0054 Heater Resistance codes even though it’s Stage 2.

I’ll ask them Monday what’s up. Weird.

I was poking around on vediamo... it is possible to simple turn off the CEL light on the dash. this is just the notification lamp, you car will still be throwing a code, but the lamp will be off. I do not know if the cars performance is hindered.
Those with active secondary O2 CEL lights on, does the car still drive 100%?

Update on my “issues” of sound and smell:

My car was sick! After putting the catless DP on the sound and smells were apparently from a limp running broken IC pump car.

Now that the car is healthy and running right the smell is no longer eye-watering. It’s still the no-cat-life smell but it’s not a crazy stink.

And the sound! It no longer sounds like a raspy straight-piped RAM wide open throttle. When the car was sick it sounded like a UPS truck when flooring it lol. Now it sounds great. Full deep blaring AMG. Not as throaty vs stock but totally acceptable again - no more buzz or blap.

So hopefully if someone reading this thread interested in downpipes they read this far to find out catless sound good when the car is not sick, and the smell is mostly bearable too.

Man you no-cat guys must’ve just thought I was a wimp.

Carry on!

And you didn't get CEL from faulty IC pump?

PeterUbers

nope; I learned this too; he got a soft code in the ecu ... IC ground fault I think

Peter speaks the truth
I had soft codes
P026A - Charge Air Cooler Efficiency Below Threshold
P023B - Charge Air Cooler Coolant Pump Control Circuit Low
that never tripped the CEL. I only found out my car was sick when it trapped 5mph lower in the 1/4 "something is wrong" and pulled that code, dealer found blown IC pump burnt harness and blown fuse. Car was just limping for who knows how long. Ugh.

IMHO the IC Circuit Ground fault is separate soft code and shows up with the always on IC pump mod and safely ignored as long as the pump is actually working.

I check my car for "soft" DTC's every week now. Silly Mercedes.

Thank you, guys!

Regarding the way a car smells when it’s Catless, I saw this in my local speed shop today. Not sure it’s the best idea though…😂
