Mk7 Golf GTI Discussion Thread

[Dutch77]

^ exactly what Adam said.

I honestly would not be worried about this aspect, as has been said don't play if you can't pay. It'd be a foolhardy customer who tried to deny the presence of a tune on a warranty claim if queried - may as well be open about things and let the dealer go into bat for you rather than be caught in a lie later.

Anyone had any luck with bike carriers on the back of a MK7 GTI?

Or how about roof racks?

[kennyc]

Anyone managed to the rattle at 2500 rpm fixed?

[Guy_H]

Is it really the case APR can reset the check sum and hence its not detectable? If so they must be one of a very very select few who can do this?

Actually when the stock binary is flashed back in by your APR dealer, then it also has the stock checksum. And the read / rewrite flash counter function also restores the original settings.

Summary, when flashed back to stock by your APR dealer, then it is 100% as it was before tuning.

World wide this has been tested in a few countries without issues when making warranty claims.

I went and had the rattle sorted out last week, they said it was the left side front passenger door. So far, no more rattle at low RPM.

Wow, that's impressive Guy. And so the resetting of checksum and flash counter is undetectable by VW?

[Guy_H]

Yes donweather, in every test so far conducted. The binary & checksum bit is actually the easier task.

Because of the worldwide turbo charger "Service Campaign" / "
Recall" on the faulty turbo chargers, it has already been tested a few times in the field.

[donweather]

Gee I wish this was more widely advertised on your site as I would have got an APR tune for sure then.

[nma]

Fuel. Depends on your foot pressure Lol. It's seems the same under normal driving as far as the cars character it is slick very polished

[nma]

Thanks guy_h. For cleaning it up

Hey Guy,

Will this campaign happen in Aus?

My GTIs turbo part number ends in "Q" which falls in the turbos that are failing.
If I ring my dealer I bet they know nothing about it, so I might just wait and see what happens.

Have you heard of any failing in Aus yet?

Wouldn't this all be academic if your car broke down, and when you called Volkswagen Assist, the attending mechanic calls for a flatbed tow truck, and your car goes straight to the dealership, without any opportunity to restore the ECU programming to stock? Given Volkswagen Australia could avoid any exposure to warranty costs, they probably instruct their dealers to check the ECU as part of the diagnosis of the breakdown.

You do realise this simply constitutes an uninstallation of the product (tune), right? The checksum is restored because the original ECU software is restored, and the checksum goes hand in hand with the original software (the two are not separable). Think of it as analogous to erasing your hard drive and installing a new operating system. So prior to service you would take your car to the tuner (eg APR dealer) and have the tune removed and the original ECU programming restored. Then, once the service has been conducted, you'd need to go back to your tuner to have the tune reinstalled (replacing the factory tune).

Yes, although it's not like this is a common or likely occurrence. Getting a tune whilst in warranty requires an assessment of the risk versus reward. If you're not prepared to take that risk, then don't tune.

From my friends in the dealerships, there certainly has been several cases of dead Audi S3 turbochargers.

I have heard a rumour from my VW contacts that there have been at least 2 x GTI's with failed turbo's.

In the US, they have taken the Audi A3 2.0T off the market & recalled all owners for turbo replacement. Even though the GTI has the exact same engine & turbo part number, Volkswagen have not recalled the cars.

This may be because they can only supply so many turbochargers in one go.

Will VW / Audi / Skoda Australia issue a "recall" or "campaign" - Hopefully they will, but knowing previous history, I certainly wouldn't hold my breath.

If your car is dead on the side of the road, it's dead. If you are modified, I would suggest towing it to your modifier for initial assessment, not use VW assist.

We have had our GTI since October last year, it has been tuned for a long time & has done over 70 dyno pulls in testing, and some long road trips. It also has the first version of turbo & its been fine, so I'm not overly concerned.
