My '13 GL350 got a clogged adblue nozzle, which took out the NOX sensor, and it had a code for an ad blue temp sensor. MB's quote was over $5,000 and they said to expect the $2,500 adblue heater in the future.

For $1,600, I had th DPF hollowed and the ECU tuned to eliminate all of the emissions functions and codes. Performance is improved, combined gas mileage is up by about 6 MPG, it looks completely stock, and I never have to worry about another emissions issue on this truck again.

If you need more info, PM me.

At how many miles did your adblue and NOX fail?

The adblue heater failed at 110K miles on my 164.

My nozzle clogged, took out the NOX sensor, and the tank temp sensor failed at 59k.

It's pretty stiff.... I would have done the emulator instead.

grumpywings

You can't emulate 4 failed parts in the adblue system. Emulators are for O2 sensors in gas engines.

I will let you know soon. I am buying the kit from VladimirCDI. It seems very straight forward for me.

DC-BENZ

There are bluetec DEF emulators, fyi.

grumpywings

Let us know who has them!

DC-BENZ

Search anywhere (Google, this board, ebay, amazon, etc...) with the acronym and word "DEF emulator". Easy....

grumpywings

No more adblue; that's a plus. But you gain no exhaust flow, pick up no power, no mileage, and spend almost as much money.

I got rid of my '12 ML350BTC at 40k miles. Can't remember the mileage when it went but I too had the adblue heater fail. Thankfully it was still under warranty at the time.

There are cheaper tunes out there too that use the fuel rail pressure to increase HP/TQ. Typically around $500.

pls send details! Want to do a re-ture or ECU flash to fix this problem permanantly. I'm out of warranty. Thx

have searched everywhere. No luck finding a bluetec emulator for a Mercedes

have a 2014 gl350 now with an engine code with nox sensor and def issue. Out of warranty and only 50k miles. Love the truck, need to do the mod you speak of. Can you point me in the right direction? Thanks

Any updates on what you ended up doing to resolve your issue?

Bern6389

im interested but I can’t PM you

BlownV8

Just curious, why do you love it?

apexit4

I wouldn’t be surprised if it’s for the same reason I’m looking to get one. Aside from being one of the better looking SUV’s on the market, it’s got a ton of space and gets really good gas mileage from the diesel given how big it is. It doesn’t hurt that it’s quite luxurious either.

apexit4

Are you trying to send a PM while on a smartphone or desktop/laptop?

Bern6389

phone

apexit4

I'd suggest trying to send the message on a desktop/laptop. I was successful in doing so on my desktop but didnt have the option when on my phone. You should be able to get around this issue by asking the site to load in desktop format if you're really intent on only using your phone.

BlownV8

The fuel efficiency is ruined by the poor reliability and more costly maintenance schedule of the diesel. Just get a 2015 or later GL450 if you want good mileage and better dependability. They get pretty great mileage if you don't drive like an idiot.

computer did work. thank you
