Assumption is the mother of all fkups... I'm running JB4, 3.5inch downpipe, CTS intake kit and a few other bits and bobs. Hitting 23psi - road tuned so no idea about bhp but I can assure you it is FUCKING QUICK getting to 120mph... that's why I am searching for a way to remove that annoying limiter. Not going to ditch my JB4 just yet only for the top speed limiter.

Obviously the limiter is irrelevant in that case as they'll never experience it.
But if you're asking whether the ECU still carries a limit, I would imagine that it does since that programming is mostly done by sales market. Only specific models (Like the Golf R) will get custom limits

You're making a lot of assumptions, not sure why though ?
. One might say you're fking up 
.We don't know (or in some cases even care) about what you're running unless you post it. Are you JB4, tuned, both?... road tuned?
And what qualifies as "FUCKING QUICK" to you?
Post some of these videos you mention showing people removing the speed limit on an Mk7 with VCDS, I can't find any. From what I recall the speed limiter bit you have un-checked in the long coding is for the speed limit function that some cars have as a cruise control function, not actually related to vehicle top speed. Even a cursory search of @MeltedSolid's history would reveal he/she is familiar with VCDS and OBD11.
I should note that my post was a joke... my car being an Mk7 TDI, that will not do 120. I was not actually asking anything.
You don't ditch the JB4 for the top speed limiter. You ditch it because it's a poor tuning solution (unless it's strictly to avoid a TD1 flag).
You can probably sell it, buy a Simos Tools dongle, and tune it yourself and "make money" in the process. I use the quotes because realistically you'll spend a bunch on fuel taking 3rd/4th gear logs because you now have thousands of tables to play around with. Plus you can add good stuff like map switching, spark cut LC and TC, etc.
@19birel switched from a JB4 to ST for tuning himself in the last year, ask him about the benefits if you want someone else to weigh in.

I'll chime in- And to preface, I LOVE JB4s for what they are, I had one on my MK7.5 and I still have one on my B8.5 Audi A4 stacked ontop of an IE tune (I was the first better tester for the B8 A4's JB4 and my dyno sheet is on Burger's website). Heck, I just helped a friend install one on his GTI last weekend.
However, they have their place and their limitations. In the end, what it does is take the ECU tune (stock in your case) and push the limits of its adaptability to make more power. On this platform we are fortunate to not only have a number of tuners available that can refine their files to your application, but options to even DIY a tune (with a library of info and a community to make that DIY option actually feasible). When you reflash the ECU, removing the limiter is a small benefit relative to the big picture; you have total control with regards to telling it exactly what to do; in short, it's the more effective way of doing things.
I did a number of 60-120 runs comparing my car on the JB4 to a tune that I made via simos tools (a Pro tune would have yielded better results) and the car was faster and more consistent once I got my bearings vaguely straight (and in hindsight the stock turbo tune I made was still garbage lol). There's some good tuners out there that will tune you on simos tools if you're not inclined to self tune BTW (Russell Road & Racing, and GLS Performance come to mind) If you're committed to the point of multiple bolt-ons, you're selling yourself short with skimping on the tuning side.
Why do I have a JB4 on my A4 still? There is no credible custom tuning support on that platform, so to go beyond the point of an OTS tune requires a JB4 unless you want to talk to the ONE guy that will custom tune those cars. Why did I install one on my friend's GTI? It would be a massive shock if he installed any bolt-ons, and he's just after a simple noticeable bump in performance- I warned him of how quickly he could approach the limiter and he laughed as he'll likely never push it that hard.
It sounds like you've outgrown the JB4- no shade towards the JB4 or your setup. Whether you go with Simostools or get a Cobb accessport and an EQT tune like many others, reflashing the ECU will take your setup to the next step and open doors to expanding it further.

Thank you! very useful info. Have not investigated the Simos Tool yet but it sounds like something right up my alley. As bad you as say the JB4 is, it kind of works for my purpose right now.. daily driver to work and back, just need a bit of more poke for the 35kms trip each way. No drag racing, or competing. Works for short bursts in traffic, or when I find the occasional Lotus, Mustang, Porsche, BMW to have fun with.
Nonetheless, going to look at the ST dongle option.

Now looking into ST or Cobb.
In any case, I was originally looking for a way to remove the Top Speed limiter via VCDS. 7-8 years ago everybody said it's not possible at all on any model. Now, loads of videos popping up on Youtube for removing top speed limiter on various VW cars via VCDS/Delphi. I haven't seen it on GTi though.
VCDS Golf 7 - speed limiter removal - not GTi
VCDS Example 1
VCDS Example 2

hmmm... food for thought. Perhaps I have outgrown it. I started off with JB4 on a completely stock car, then slowly added downpipe and CTS intake and the other bits over a 18 month period.

Ok, now you post some useful info... joke was fking stupid, so you get a stupid answer.
Thanks about the cruise control bit (pun intended). I'll look into that further.
Here's the videos - ever tried searching Youtube perhaps??

Let's come back on topic now.
You've got the wrong interpretation of those videos.
Some commercial vehicles are "speed limited" for insurance, legal purpose, etc. Could be your company doesn't want employees driving work vehicles over the speed limit, so you limit those fleet vehicles to the legal speed limit of 65mph, for example. Those videos are simply removing that restriction, they are not removing the top speed limit. In the videos you linked, in the beginning of Example 2 & 3 (work vans), they're saying exactly this.
Speed limiter =/= top speed limit.

Your use of Youtube is trash... you didn't post a single video that has anything to do with your car. Only one of them is even an Mk7 Golf and it's a 1.6 TDI.
I post useful info whenever I have it for anyone who asks... no interest in helping you though.
There is a reason why only a Tune will remove the speed limiter and not a simple VCDS tweak. Your examples are not example of this platform, just because it can be done on lesser models that have a lower speed limit doesn't mean you can remove a GTI's or R by the same method. If you did a search and nothing came up.. That because there is no way of doing it. You obviously are not familiar with what you can and can not do with VCDS. Get your self a stage 1 OTB tune and move on. You are in Dubai? and don't have an upgraded intercooler? a speed limiter is least of your worries.
Yeah, I'm confused by the Youtube videos. Specifically what I declared in my first post... and I asked for help with it!!
You claim to have all the answers, but so far you're only here to find problems... Better you go jack off elsewhere and get your pleasure looking at yourself in a mirror. I don't see any intent to help - only stupid jokes, childish comments and an over-inflated ego.
Either post something useful or otherwise stop messing up this thread.
Thank you sir for this explanation. That was not obvious from the videos, or from the Google search results.
Starting to make more sense now though.
Ok, please enlighten me? What is that reason that only a tune can remove the speed limiter?
I'm trying to gather facts and willing to learn. That's why I came here asking questions.
No offense, but I still don't feel like you know for sure the answer to my question. You seem to be wrong that it works on lesser models but not GTi or R models. Others pointed out above it's also NOT possible on lesser models and that the videos I posted are actually for something else.
I also think your stance on search results is narrow-minded - if nothing comes up in the search then you just close the book on that.. not my style at all.
Intercooler - different topic altogether whether you're right/wrong about it. Let's stay on thread here please.

Because it's in the calibration block 5 of the ECU. There are 4 tables for maximum velocity, likely due to different markets having different limiters but I haven't looked into it. You can just set them all higher and no longer think about it. You cannot do this with VCDS. Yes, I have VCDS and know what it is.
