2018 GTI PP Won't DSG Fart

[clarky92]

Looking online at other owner reviews, looks like Im not alone. New DSG7/ software for the GTI looks like the cause.

Hello clarky92,

On this subject, do you know anything about the respect of what might be the reason why these DSG FARts are not produced?

This week I'm going to receive a Golf 7.5 Performance and it has left me worried, as I assumed that it was obvious that this model also made them.
It seems that a user has reported the same problem and attached a screenshot showing that the Golf R has exactly the same gearbox (DSG7) but different software...

If that is the case, does anyone know if the software can be updated or if the VAG brand itself could call for a revision to update the software?

Thank you very much and greetings from Spain

The GTI 7.5 PP has different dsg software to a non PP 7.5

Only way to get the dsg farts back are aftermarket dsg tune

Only think I dont like about my 7.5 PP - the dsg farts were awesome on my old gti

I have talk to one of the best tuners in Sweden, that have made new software to the 7,5 PP  and the DQ381 DSG. 

And it is NOTHING to do with the new DQ381!

Is is all in the software to the Engine!

VW have big problem with warrenty on Catalyst that the DSG farts cause  . So they have talken away the "farts" on the PP to Save the 2 Catalyst that is standard on the PP nowdays...

That change to no fart has coincided with the introduction with the new 7 speed DSG box....
Cars with the old 6 speed should do it, new 7 speed highly likely won't.

I test drove a mk 7 PP DSG "extensively" and it did make DSG farts alright.
I've got a new mk 7.5 PP DSG with about 6000 km on the clock now and it definitely doesn't make the same pops.
On the other hand, I think there is more noise in general out of the larger mk 7.5 pipes.

My understanding of the reason behind this relates to differences in the exhaust system, and likely engine software to improve fuel consumption and CO2 emissions etc.

It doesn't have anything to do with DSG gearbox and/or software.

The exhaust system (predominantly the catalytic converters) are newly designed and much more restrictive on the 7.5 Performance/Non-Performance. There are no differences in the exhaust system from 7.5 Performance/Non-Performance they are identical (same assembly, part numbers etc).

This is some great information, are you 100% sure that they are the same exhausts? I wonder why the Performance sounds a more throaty that the normal one.

I will 100% confirm that there is a difference somewhere there must be.

My 7.5 with NO PP and 6DSG made very loud DSG farts from new .

My 7.5 WITH PP and 7DSG makes no DSG farts what so ever.

I'm sure, I checked because I noticed my 2018 7.5 Performance didn't sound anything like a 7 Performance so I was intrigued.

Part numbers and assembly are identical, the only difference I guess is engine ECU software owing to power difference (again other than gearbox, there are no physical differences between a standard and Performance model engine.

The standard/performance models run different engine codes but as far as I know there are no significant or any hardware differences it is purely software. The engine codes used in the non performance 7.5 are an older variant e.g. CHHA than the newer variant DLBA etc in 7.5 PP so may be subtle differences there.
