Emissions Modification: As described above, Porsche will perform an agreed-upon emissions modification that modifies the emissions control system software on your vehicle. Drivers may notice some differences in vehicle operating characteristics after the modification, but other than as described in this booklet, drivers should not notice any adverse changes in vehicle reliability, durability, performance, drivability, or other driving characteristics. The software upgrade approved by EPA and CARB will only change the way your car’s engine and emission control systems interact. - Clearly that's not the case. Or, if it is, there is something else defective in the vehicles not caused by the fix.

The new software will affect your car in the following ways:

• Engine sound may differ somewhat from your vehicle’s prior operation. There might be a difference in combustion noise from the engine that may be noticeable during vehicle warm-up. The potential change in sound will not result in any <span style="color:#e67e22;">noticeable changes to the driving characteristics</span> of your vehicle. <span style="color:#2980b9;">-OK, it'll sound a bit more like a diesel. I can live with that, especially since it won't make any changes to the "driving characteristics" of the vehicle. Great, the noise isn't the cause.</span><br />• Shift Patterns – The shifting behavior has been adapted to run with slightly higher engine speeds during vehicle warm-up and when driving at high altitudes. <span style="color:#2980b9;">-Mildly annoying, but I get it, you have to get everything up to temp quickly. Fine.</span><br />• Downhill Driving – Removal of the enhanced automatic engine braking feature may require drivers to apply more brake pedal in downhill driving. <span style="color:#2980b9;">- Sucks, but it wouldn't have changed my purchase decision, so not having it isn't a big deal.</span><br />• In Sport mode, some drivers might notice less dynamic shifting behavior. <span style="color:#2980b9;">- Less dynamic would be OK. Totally MIA, not so much.</span><br />• Diesel Exhaust Fluid (“DEF”) consumption – DEF (also known as AdBlue®) consumption for your vehicle may change. MY15 vehicles may experience an increase of 40% on average, while MY16 vehicles may on average experience a decrease. The exact amount of the change will vary depending on driving style and other factors. This means some drivers will need to refill the DEF tank more frequently; however, we anticipate that a full tank of DEF will last through a full 5,000-mile recommended service interval. <span style="color:#2980b9;">-Think we all knew this one was happening. No big deal; DEF is cheap at Walmart.</span><br />• Decreased Fuel Economy – Your vehicle’s fuel economy will decrease by up to 1 mpg, depending on driving style and habits. <span style="color:#2980b9;">- Yep. Fine. About right in town. On the highway, no noticeable difference.</span><br />• On-board diagnostic (“OBD”) system changes – Your OBD system’s operations will be modified based upon the agreement with EPA and CARB and will be compliant with existing emission standards. We do not anticipate that the modification will affect the OBD system in a manner that would make identification and repair of any components difficult, compromise warranty coverage, or compromise your vehicle’s ability to comply with the inspection and maintenance (Smog Check) test of your vehicle. Furthermore, the extended warranty coverage outlined in this booklet offers additional protection for any OBD-related issues. These changes should not be noticeable to you and do not have any impact upon driving characteristics. <span style="color:#2980b9;">-Good to know. The system will still report on itself and can be used to troubleshoot. Except for the current problems impacting drivibility.

But my dealer is excellent and agrees with my concerns, so we'll see.

I've had the opportunity the last couple of days to drive the exact same route at the same time of day at different temperatures. Sunday was 70 deg, and I saw 32.1 indicated MPG for a 15 mile run. Monday was 82 degrees, and I saw 26 indicated MPG.

Just another data point.

Edited for space and personal info.

Mr. ,
While the roads traveled and loads carried may be the same, a wide variety of additional factors contribute to the MPG seen on any trip. Multiple evaluations of your vehicle have confirmed that your vehicle is performing to spec for this engine type after the emissions modification. To reiterate, we would not be able to make any modifications that would attempt to return your vehicle to a pre-emissions modification behavior.

per the settlement agreement, your vehicle was modified with your approval and you were compensated for the changes made to the behavior of the vehicle.

Subject: Re: (5473239)

The milage when not towing and towing has suffered more that 3 MPG not towing and 5+ towing. This is much more than the stated 1 MPG. Each drive is on the exact same road with same load inside as always and same trailer when towing. This shows the Cayenne is not performing to the approved specifications of the emissions modification. I used to see as high as 37 MPG and now rarely break 30. To date multiple parts have been replaced with little to no impact on the concerns over the course of three service visits. The team at Porsche Minneapolis directed me to contact your team as they stated they can do nothing without direction from PCNA.

This is not my first VW group vehicle (12 cars in 15 years).

I have included Doug as the regional VP.

Thank you for your email. Based on the previous technical evaluations, your vehicle is performing to the approved specifications of the agreed upon emissions modification.

While the performance is different than when it was originally delivered, our evaluations indicate that it is performing in the manner expected after the modification as outlined in the pamphlet titled "Important information about your Porsche Cayenne Diesel". We would not be able to make any modifications that would attempt to return your vehicle to a pre-modification behavior.
