2016 edge sulfur smell under hard acceleration

[radicalfury]

I've had this issue since the beginning of time and dealer has not figured it out or done anything about it.  It happens especially when hot out side , AC on.

 

They tried the glue and reseal method in the TSB but no fix. I'm thinking it has something to do with the PTU or trans, but they say they cant replace the PTU unless its leaking. (or Cat?)

 

Any help would be apricated !

Is it a rotten egg sulfur smell - if so that happens when unburnt fuel get into the CAT.

 

What TSB are you referring to?

[radicalfury]

Yes Rotten egg sulfur smell fills the cab under hard acceleration on hot days..

 

They did this tsb:

TSB 14-0201

EXHAUST SULFUR ODOR AFTER HARD ACCELERATION – CLIMATE CONTROL IN RECIRCULATION MODE ONLY

Publication Date: October 28, 2014

FORD: 2011-2014 Edge
LINCOLN: 2011-2015 MKX

 

I printed it and they did it but it didnt change anything.

 

The vehicle runs good though other then this.

That TSB is for the older generation Edge. There is a newer one for 2015+ models (TSB 18-2057 - link). To test if this is really you issue, run the A/C in outside air mode (recirculate off).

i was incorrect , that was the TSB they used.  still no change.
