Help! 
 

My 2019 Kodiaq Sportline (petrol) is misbehaving and producing no error codes, which is leaving the dealership here in Aus somewhat miffed. 
 

Notes: 

78,900km on odometer 

premium 98 fuel used without exception, I look after my assets. 
current summer outside temperature between 30 to 38 degrees Celsius. Winter temps -5 to 10 degrees Celsius. 
 

Issues are: 

1. clunky shifting, delayed gear selection, bunny hopping at low speed from the DSG, has trouble deciding which gear to pick. E.g. on uphill acceleration, will drop down a gear. Accelerating out of a corner, delayed response. 

2. overfuelling, 45 per 100k at start up, overpowering smell. Highway 8.5 per 100k, around town, 15 per 100k. Generally the car sits at 9 to 10 per 100k around town and 7.5k per 100k highway. 
3. high pitched whistle inside cabin, present while driving, idling. 
4. delayed response under acceleration, turbocharger begins operating at 2000RPM, though intermittently sounds and feels as if it’s losing pressure under boost. 
5. When using the air conditioner, loud whirring under acceleration, car is at peak sluggishness and requires heavy acceleration with little response. 
 

Worst of all, no error codes! Dealership had my car three weeks and ‘could not replicate’. 
 

Appreciate any guidance/recommendations please. 

Edit: point one, change up a gear. 

Difficult to help from a distance.

 

Have you driven the car “briskly”, or attempted to, in manual mode to see if the engine will Rev up to maximum in a lower gear?

And generally drive in an acceptable way.
 

Most auto cars default to “eco” mode of driving with the aim to reduce fuel consumption, but it often turns out to be far too sluggish for some of us.

 

I can only imagine any fault will lie within the gearbox change system or in the fuel control system.

 

Running in manual will help separate an engine fault from a gearbox fault.

Likely not the issue if it is a MCU / DSG issue as there are a growing number of,

but,

when were the spark plugs replaced, or have the techs had them out and checked if not replaced?

Thanks for your replies, appreciate it’s difficult to give advice from afar. I haven’t tried running manual, will give it a go. 
 

I’ve suggested to the techs, spark plugs, gearbox faults, solenoid issues for both gearbox and turbo. Response is ‘we’ve re-mapped your gearbox, BP fuel is very smelly, no it’s not a fault with gearbox or the car and we’re not getting paid to do this’. 
 
So far it’s been difficult to have them say what exactly they’ve checked.

 

And yes, have tried putting the boot into it in sport mode and standard. Issues remain. 

@Ellevee  The recommended schedule for the spark plugs replacing is at 64,000 km / 40,000 miles.

Were they replaced then or since? 

No idea. It would seem not though. My mate had an issue with items not being replaced per service schedule. I’ve asked, I get fobbed off. No longer have the report from the 64k either. 

Sounds like you need to go to a different dealer. 

Not much choice in my city. Interstate and currently at another about to test drive
