MK6 -v- MK7 : Golf GTI

[WhiteJames]

Oil Temps & Fuel Consumption

The Golf 7 GTI is designed to run hotter than the previous MK6 Golf GTI. My understanding is that the MK6 was designed to run between 95-105 degree with thermostat fully closed at 95 degrees and fully open at 105 degrees, with the medium being 100 degrees. The Golf 7 GTI is supposed to run higher at 110 degrees apparently to reduce frictional losses, making the motor more efficient.

The difference in warm up from Golf 7 GTI (95 degrees) compared to the MK6 GTI (80 degrees) was done many times. The ambient temp doesn't make much of a difference in this respect. Nor does it make a great deal of difference between mid winter & mid summer when doing a 12-15 min steep mountain climb up Macquarie Pass - perhaps 2-3 degrees max difference.

I know that climbing the Macquarie Pass inland of Wollongong had the old MK6 GTI at 113 degrees in winter and 115 degrees in summer. Others say that their MK6 Golf GTI was about 115 degree oil temp towards the end of a 20 min session at Wakefield Park in Winter. So the mountain climb run-in with revs between 2-4,000rpm with light throttle application is putting a good amount of load on the piston & rings for a good bedding in process.

I haven't monitored fuel economy closely, but generally the Golf 7 seems to be more efficient by about 0.5 - 0.8 litre per 100km. Mind you, I have a Manual Trans with no options on the Golf 7 GTI that is considerably lighter than my reasonably well optioned DSG MK6 GTI (1320 kgs -v- 1380kgs approx). Fuel consumption is way over manufacturer's claim, but I would be confident in getting near the stated claim on a long highway interstate freeway trip, perhaps within 0.5 litre per 100km.

I was going to test drive a PP GTI to compare to my Std Golf 7 GTI Manual Trans during service time, but the local dealer didn't have a demo PP GTI available for comparison, so no review on the PP GTI for now.

I remember u testing and reviewing the 86 / brz. Why didnt you go with the rwd 86 / brz and chose a manual mk7 gti instead?

Fuel consumption is way over manufacturer's claim

That's been my experience also. I'm hoping the explanation in my case is a tight (<200Km) engine.

Go see Keith @ Mascot for a deal! ps i sent you!

86/BRZ do not have adaptive dampers for a start. Here's a video showing that semi-active adaptive dampers on an Audi S3 sedan really do make your VAG vehicle go faster around a track. Okay ... maybe the throttle response has something to do with the lap times in addition to the suspension tune:

Golf R has the feel. GTI has the stats!

How is APR tune with new mk7? must be good!?

Do you know anyone that has it done? Its goes up to 310bhp which I think the front wheels would struggle with, make me think would it be worth it?

After 18 months of trouble free ownership of my GTI manual ... I've lately been putting my GTI function into 'Individual'. The only difference from Normal mode in my application of Individual mode is that the throttle is put into Sport mode ... nothing else is changed.

This lengthens out the throttle travel and makes power delivery feel more linear. This helps prevent the front wheels spinning up, lighting up the TC light.

Ironically ... Individual mode with throttle in Sport and all other functions in Normal mode appear to tighten up the dampers too. I've noticed that dampers feel to be pushing the tyres into the roadway with greater rebound compression, aiding traction in addition to the more sensitive & linear Sport tuned throttle application.

Downside is that you have to put up with the sound-a-kator Sport cabin noise making that less than appealing warble noise.

Thanks for that. I'm still rotating modes & trying to work out the differences between them. Might be a while before I work it all out, but posts like yours help.

After 3-4 months I've changed from individual back to Normal mode. Feels like a slightly different GTI. Individual with throttle in 'Sport' began to feel like the gas pedal was a well modulated, but grainy.

Cold Start Up

Had my Golf 7 GTI serviced recently. I left the GTI overnight at the dealership so as the dealer was able to do a cold start first thing in the morning. Reason being is, unlike my previous MK6 and MKV GTI's, the 7 GTI's motor seems to shudder for the first few minutes after initial start only when motor is cold. Dealer hooked it up to the diagnostics and said that my motor is within 1-2 percent of recommended readings. It was also stated that the cold motor warm-up shudder is not uncommon for the Golf 7 GTI as the ECU dumps lots of fuel into the motor for part of the first minute during initial warm up. It's great that the motor has not used a drop of oil in about 2 years.
