The Haldex modwould go well with upping the XDS intervention too from standard to strong. I have the instruction for that but it asks for a password which I don't have. It's in Module 03 - ABS and I'm entering 31347 which works for other mods in this module but it's not the right one for the XDS modification.

[03] ABS

Adaptations

Expanded electronic differential lock

Change from Medium to Strong

I tried this on my 280 and got an ABS warning and then the module was unaccessible.   I tried it on two previous XDS equipped cars with no issues, I found it makes a big difference.  You can feel the inside, front wheel 'digging in'.

I used OBDEleven and didn't get an error per se, but it kept asking for a password, where normally it should say Adaptation Successful or something similar. Did you go with 31347 too? Maybe we need to find the correct password for this.

Tried on a FWD car before with XDS and there was a small improvement indeed. I am thinking it should work much better on a AWD car since it will have the rear outter wheel doing more work.

I too used OBDEleven.  I think I used the password which is referenced in the sticky on the VCDS adaptations thread.

 

A quick google suggests 40168 or 20103 may also be worth a try.

Hmm, you are right, 31347 is for 09 - Central Electrics. I might have simply messed up as I was spending some time in Module 09 before trying to switch Coming home lights to Fogs (unsuccessfully cause the names in the original description don't match the available options in OBDEleven or they have been renamed/moved in a MY19) I'll give those other two passwords a try.

I wonder if I did the same and that's why an error was thrown (?!)

 

The OBDEleven dongle is in my wifes Golf at the moment so I'll take a look later.

Negative. Just went and tried 40168 and 20103. The first one just didn't work. The second one seems to have worked but the car made an audible warning noise and on the dash the message "no brake servo" came on together with a couple more error icons. I didn't want to screw something up so I re-coded the original value, turned off and on and no errors left and the car drove ok. Didn't do a full SCAN to see if some error has registered and needs clearing but I'd rather leave it stock till we know more about this.

Something defo changed between MY17 and MY18. I recall a servo/ABS warning when I applied the values too. I also reverted the change but then the controller seemed to be locked for further changes. 

 

It it worked with no issues previously. Perhaps there’s additional coding required with the presence of the Haldex system?

Module 22 - (All wheel drive control)

Adaptations

 

Acoustic measure, wiring logic

Change value from "Standard" to "Increased traction"

Go out and give it the beans 

I applied this before dinner, will test drive tomorrow.  Thank you! 

 

No joy with the ABS module SAC but I've been googling around various forums and it appears that a lot of people have been having issues accessing this module since 2013/14.  Even some RossTech Techs don't seem to know what the code is. (or they offer a few up, but none work - some I've referenced in previous posts) 

 

I've had a look through the OBDEleven boards too...nothing of help there either.  

 

 

I'm now a bit confused as when I've checked the ABS-03 module via OBDEleven the XDS diff is already set to strong and I can toggle freely between weak/standard/strong without being challenged for a code.  No errors are thrown at all. I've done a scan after going for a drive and no codes are logged.  The only thing that has changed is both OBDEleven and Android OS update....

 

..so on this drive I got a chance to try the 'Increased traction' setting and I'm fairly certain the car feels more planted/stable, almost like it's hunkered down in the corners when under acceleration.  Could very well be placebo, who knows?  It's a section of road that I often drive and I'm quite confident that I could detect a difference; it was wet too, after a heavy downpour. 

 

 

I was travelling all day today. So maybe even if it gives a Servo warning, it actually accepts the coding and errors are removed at next switch on? I didn't really give mine a chance and reverted it to Standard setting immediately but that's the only way I can think of of having stored a modified setting for XDS (even Golf R and S3 are set to standard from factory so Strong must have been a value you set yourself).

Regarding the effect of the Increased Traction setting, what you describe is reported by R owners too. How accurate? Hard to say without some fixed parameters (speed, angle, g's etc) but I also believed I noticed something improved when trying this, especially considering the wet conditions. I am still exploring the car so it could be partly just my imagination but my impressions match your findings, and you are much more familiar with the car having owned it for some time now.

@newbie69 out of curiosity, did you try the Audi throttle mod on your Sportline before you fitted the pedal box? 

 

I was reminded that the option was available when looking for the access codes for the ABS module.  I tried it on my 150 TDI manual and it made no difference but I was going to give it a try on the 280 BUT....I've seen a few posts that mentioned the change caused ACC errors that didn't go away when the change was reverted.

Not really because I remembered it had little effect on the GTI, and not really comparable to the pedal box so since I had the box available I just went ahead and fitted it. After two days it already felt like the car came like that from factory so this initial "surprise" the box provided went away, my foot became adapted to it and now I can give little, average or full throttle from as low/early as possible as I feel like.

Thanks. I guessed you went straight for the pedal box option 

 

I think I need to buy another RaceChip XLR....

Well of-course you do, no reason for italics there...  Seriously, the effect on a AWD car is so greater than on the FWD GTI.

Why did you have to say that?!? 

 

I've had to drive the car a little more today and I'm fairly confident the haldex changes you helped with have made a difference.  The car now feels much more planted and that's on all-season tyres, on very wet roads

Well only because it's true! I know I'm not helping but consider you've done it already, it's such an appreciated improvement on this car.

You might want to keep an eye on Parts for sale in MK7 forums, especially the UK GTI forum. I got my DTUK box for around 120 pounds iirc, and they seem to come up for sale every now and then. Last one was sold for 90 pounds as I see. These are practically wear-free items for so you can make some good savings compared to the retail price. I can PM you links.

...and the box was interchangeable from Golf > Superb with no reprogramming or similar required?   I know my XLR wasn't compatible but fuel type and gearbox are completely different. 

 

Thanks for the advice, appreciated.  It's expensive but still appreciated

Nope, and it behaves faultlessly. To be honest, I didn't bother asking DTUK given that's it's simply a signal modifier and that it would at worst not work if it wasn't compatible . Consider that mine is a MY19 272 with a different engine code than the Golf (no more CJX), for a pre WLTP 280 like yours I would be really surprised if any pedal box for the MK7 wasn't a direct fit.

Was your Golf DSG?  I'm just wondering if all the pedal boxes for the TSI are compatible regardless of transmission type or there's different versions for manual vs DSG.

Yes, but there wasn't an option depending on transmission type anyway.

Ah valid point, thanks. Race Chip don’t list a transmission option, just car/engine. 

 

Conveniently there was an XLR unit on eBay from a former Golf R owner. He accepted my best offer so I should have it early next week. 

 

Thanks again for the help. 

The XLR arrived today and funnily enough so did an email response from RaceChip Tech Support who claimed that the pedal box for a Golf R 7.5 would not be compatible with my 280.  They were pretty adamant it will need 'reprogramming' to the tune of £109....

 

Naturally I just fitted the box straight away and it of course just worked as I would expect.  Pffft it makes me wonder if the box from my 150TDI would have been compatible.

 

Not had chance to take it on open roads just yet but wowsers! It makes the accelerator very snappy indeed, especially when you get into manual mode and blip down a few gears.  Race + mode is erm 'interesting' 

For all us `Dunces`..., well I'm assuming its not just me...what is a `Pedal Box`?

It's a device which intercepts and then amplifies (or even reduces) the signals which are sent from the throttle position sensor to the ECU.  It's commonly known/moaned about that there's a dead spot or lag when first pressing on the accelerator pedal; the pedal box plugs directly into the throttle body and fundamentally tricks the car, so whilst you may only be applying 10% throttle, the box will do it's 'magic' and tell the ECU you're applying 30% throttle. So why not just press the throttle harder and save money?  In theory that would be the same but what the pedal box also does is speeds up the signals sent from the throttle on to the ECU, which in turn makes the car react quicker to throttle input.  They really do work IME and as mentioned earlier in this thread, they can make the car feel like it's producing more power (when in fact the box does not alter the BHP of the car) 

 

There's a few different models/brands, DTE, DTUK, RaceChip and they all work on the same principle.  There's usually a few different settings on each box which vary how the box will react.  Here's the RaceChip blurb: 

 

https://www.racechip.co.uk/pedal-box/xlr.html

 

Then you have 'tuning boxes' which do actually alter the power of the car but that's another thing altogether.   Take a look around the RaceChip website and you'll see what their tuning boxes do.  Again, a few different companies sell them and they all do a similar thing...spoof the car to think it's producing less power than it should be, so the car overcompensates and produces even more.  Crude but effective and gives people the chance to modify the performance without going down the remap route.  They can work well and some are better than others IME but a remap is superior and arguably less harsh on components.  

Thank you so much, `Penguin`, for your comprehensive reply.
