Title: GTI mk 7 under preforming
Post by: bsides on 19 September 2018, 14:37

Hi all,
I've just purchased a 2015 (22k mile) GTI DSG performance pack, and I'm a little under whelmed in all honesty.
The Car was VW approved and is in mint conditions however it lacks the torque my Mk6 had.
At times it goes how I feel it should but it’s very inconsistent any suggestions, I have been putting standard fuel and will switch to high octane on my next fill.

Any other suggestions would be welcomed??

Thanks

Pedal box and stage 1 tuning box? Probably the pedal box will do what you think you are missing anyway...

There's always the new DSG tuning plugin too - early days but that probably also would help.

It might be a simple case of your not used to the appalling throttle response of the mk7 / mk7.5?

I've never owned a mk6 so don't know if it was the same for that model but lots of people say the lack of low end torque / response  from the mk7 is down to the electronic throttle cable which can be cured by a pedal box.

I've owned a 7.5 GTI for 8 months now and it's the most annoying thing about the car. Especially i find when you are in sport mode with the soundaktor turned up to max as you put your foot down, get this ridiculous loud noise, but dont actually go anywhere for about 5 seconds and then your away.

I also find if your not in the sweet spot in 2nd or 3rd (3500 rpm plus) then the performance anywhere else is very underwhelming but that all depends on what you have driven before.

Honestly, my 2005 MK5 GTi had better throttle response than the 7.5!  :shocked:

Could make a game out of this...

Lets list things more responsive than a 7 / 7.5 GTI..

My wifes 1.0 fiesta
My 1989 MG mastreo turbo
My dad's 10 year old diesel transit van

Sure there's lots more people can think of.

Why didn't you stick with your MK6 if you're not happy with the MK7? Have you gone from a manual to DSG?

You can tell a small difference with better fuel but not much.

I don't have any issues or problems with the throttle response on my GTi pp. Has the OP checked when the car was last serviced? Some decent quality fuel would probably help too.

if it was mine I would be rolling roading it to make sure it is as it should be to put my mind at rest. At a guess Ive not heard of a mk7 diverter valve failure but what you are saying is how a mk6 feels when its dv is failing. Delay in pedal responce is worse on a 7 but they have more torque.

I had a mk5GTI for 10 years and my 7.5GTI's throttle response in std form is incomparably poor.  The mk5 felt much more muscular and torquey.  With a pedal box fitted the 7.5 now has missing instant, torquey response.  Without the pedal box it feels like driving with the handbrake on and four flat tyres.  I don't know of one person who has actually used the pedal box who doesn't think it transforms the car's throttle response.

Try one.  They're a cheap and easy fix.  If you don't like it, they're easy to sell on.  I will bet money it will change your opinion of the car.

Edit:  There's a pedal box thread on here I'm too lazy to link, if you want more reassurance.

Second this, they make a serious difference

Pedalbox= the way forward..they do work money well spent!

Don't often venture on the Mk 7 threads as I still have my 2010 Mk 6. Interested in this thread. Found the throttle response on the MK 6 quite good until we acquired a Polo GTI (1.8 ). Wow what a difference! If some find the MK 7 throttle response poor then glad to wait and see what the MK8 brings.

'At times it goes as I feel it should, but it's very inconsistent'.  I would 100% agree with the OP on this, and it really surprised me when I got the car (and not in a good way).  I've driven my 67 plate Mk 7.5 GTI 230 manual for 8 months/9k miles now and the throttle response is (for me) by far the biggest gripe/annoyance with the (otherwise excellent) car.  I bit the bullet and bought a pedalbox for the car a couple of months ago - I would whole-heartedly recommend one as it is an excellent bit of kit for very sensible outlay - however the truth is it hasn't 'fixed' the problem, it just masks it much, much better.  But it is crazy that the pedal response is so erratic and poor - am really hoping that the negative feedback makes it's way successfully to VW and that it is resolved on the Mk 8 GTI.

Almost certainly what you perceive as poor pedal response is a design feature to meet emissions targets.

That 100% won't get any better with the Mk8

I'm pinning my hopes on the mild hybrid system improving throttle response. Fingers crossed.

I totally agree.
The mk7  was the first of the new generation of low emissions engines the type of which seems to have been adopted by other manufacturers too as they all seem to have dreadful pedal response now.
It completely masks the prodigious torque these engines produce with a very laggy and flat power delivery.

I somehow doubt the hybrids will improve upon the situation until the aftermarket get their hands on them.

Presumably though wouldn't the lack of emissions from a hybrid (when accelerating) mean that they could use it for torque fill and actually fix the problem....surely it is the exact solution to the problem!

In theory yes, but the actual throttle pedal is the same component across the range and that's where the issue lies. There's a chip in the top of the assembly which sends messages to the ECU.
Unless VW group start using a different accelerator pedal in each model then the issue will remain so long as there are petrol and Diesel only models in the range.
Just my suspicion, I'd absolutely love to be proved wrong.

Having read this as a newbie and experiencing the poor throttle response a DTUK pedal box has been ordered!!!

Hypothetically - what are the possible ramifications of fitting a pedal box without informing your insurance company?
Title: Re: GTI mk 7 under preforming

If you have an accident and the insurance company find out then your policy will be null and void.

For modifications in general, there  are a number of possible ramifications if individuals fail to inform their insurer of modifications;
So, although a pedal box doesn’t increase bhp - it removes the initial dead throttle response - it is a modification and should be declared. It is just not worth taking the risk of not declaring the fitment of a pedal box - or any other modifications for that matter. You could end up uninsured and have a criminal record, and have significant issues getting affordable insurance in future.

If you rear end someone or have a low cost accident you'll probably be fine. If you kill a family of 6 and a few peds and it's your fault they'll probably try and find any way to get out of paying and will find your undeclared box and you'll be f**ked.

You could probably risk it and be fine though, yolo and all that.

FWIW, my insurance company covered the pedal box.  I had face to face discussions with them, rather than rely on their call centre staff.  I showed them the PB+ instructions and documentation and they agreed as it isn't a performance modification it is fine. 

But I've heard some companies won't cover a pedal box.  So best to check first.
