118TSI - General Discussion

[DracZ]

on some versions, you press the setup button for more than a minute. it will first display the setup menu but continue pressing and it should then display a supplemental menu that shows version info amongst other things.

Maverick has a website:

mr gee - Is that pic from your 118TSI? When was it delivered if you don't mind me asking? Trying to figure out what version RNS-510 the latest Golfs are shipping with, cheers.

Reset on 7 speed DSG:
With Engine and Gearbox at or near the normal working temperature.
No igniton on, key out of steering lock. Press accelerator full home until the switch is felt at the bottom and hold it with the switch "on" for 10+ seconds. I used 20 seconds to be sure.

Now drive it normally in DSG "D" mode but ensure you drive this sequence. In the first few minutes take it from low speed (20mph) all the way upto 70mph and 7th gear and then back down to a stop. Coming back down can be the next junction a couple of miles down the way so no need to block the highway. Let it creep at 5mph-ish under no throttle condition while in 1st gear for a few feet (20 feet) to learn that. Job done.

Has anyone tried this?

Is it something official, cause ive never heard of a dealer say this

The pic is off my car but my RNS is not OE delivered but something I picked up off a group buy

Reset on 7 speed DSG:

Just to add a little more. I found the procedure on here, its documented several times if a search is done but...... I came across a comment from "Logger" that appeared to cast doubt on it. So I decided to conduct a few of tests.

As above the DSG 7 Speed Mechatronic Control Unit is always adjusting to your driving patterns long and short term.

I drive in urban traffic crawl 80% of use of the car in any given week. ie, average journey time is 15 to 20 mins, distance is 6 to 8 miles and average speed is 20mph with a road speed limit at 30mph.

At junctions, the throttle didn't respond on setting off, press, nothing for about 0.25 seconds, reaction was to press more and the engine spun into life, as did the wheels! Gear changes from 1st to 2nd were always a bit lurchy as were some higher ratios if accelerating at mid throttle settings.

So with that in mind I first of all changed my driving habits, ie. instead of casually driving along with very light throttle all the time, I drove more agreessively on the throttle, chose faster routes. Did this for two weeks. Effect: Nothing

Next, drove the set-up sequence above without the throttle/no ignition action. Did it twice two weeks apart and assessed for two weeks each time. Effect: Nothing

Then did the throttle/no ignition for 20 seconds action and immediately drove the set-up sequence I wrote above in the following 10 minutes. Effect: Result!
The engine immediately responded to pressing the throttle when setting off at junctions. It felt connected directly to what I was doing with my right foot. The 1st to 2nd gear change happened smoothly, all other gear changes cannot be detected, even under fairly hard acceleration. Releasing the foot brake, the gearbox immediately enages "creep" (5 - 6mph) mode whereas it used to think for a second before enaging the clutches.

I cannot find anything official on the web WWW about this. If someone has a copy of the VW's ELSA workshop programme dated post-2007 edition (mine only goes to 2003), what does it state about conducting a "Basic Setting" sequence on the 7 speed DSG in the gearbox section of the maintenance manual?

The 6 speed DSG "Basic Settings" is well documented on the Ross-Tech VAGCOM web site and in that case, it is necessary to use the car's diagnostics with something like VAGCOM. I borrowed the drive sequence from there as on here from what I could find, there was only mention of pressing the throttle but no after set-up process of learning for the Mechatronic Control Unit.

This is the 6 speed drive learning sequence documented by Ross-Tech Wiki (VW Golf/Jetta/Bora (1K/5M)) after using VAGCOM to reset values in several parts of the 6 speed DSG:

"Defined Test Drive
Suggested test drive after replacing the mechatronic or successful basic setting:

ATF Temperature 30...100 °C (86...210 °F).
Drive in Tiptronic Mode from stand still up to 6th Gear.
While doing that make sure to drive in Gears 3 or 5 for approx. 5 minutes and also in 4 or 6 for approx. 5 minutes.
The engine speed window for all gears is 1200 - 3500 RPM (for clutch calibration).
Perform one sharp braking followed by a full throttle acceleration (oil return check).
Evaluate creep and starting-off points."

I noticed the exact same issue when test driving the 118TSI, will definitely give your method a go once I take delivery of the car, cheers!

Seriously... where in NSW is this 'test track' that the VW dealers would be using to perform this procedure! To drive from a standstill, and make their way up to 6th gear, but taking at least 10 minutes to do so because they need to drive in 3 or 5 for five and then 4 or 6 for five. hehe

Maybe this trick is acuatally recalibrating the throttle/throttle position sensor.

Possibly but why does it affect the clutch engagement in creep mode and initial set-off.. The engine RPM hasn't changed. Also noticed the DSG clutches engage immediately on foot brake release no matter whether setting off or creeping along with no throttle pressed. As said it needs someone with ELSA to look at the DSG set up (& throttle).

RW1, What you are describing here is the process to fast adapt the DSG6 AFTER it has been successfully reset to basic settings. As you have alluded there is a similar but distinctly different sequence for the DSG7. It of course omits the oil return check (as it has dry clutches) and adds quite a bit of other stuff.

The test run is a perfectly valid thing to do to speed up DSG adaption post reset, which would happen over time in any case. But importantly this drive process in itself does not reset the DSG. To this I think you alluded to as well.

My skepticism is purely about the idea of holding the accelerator to the floor for ten seconds with the IGN OFF or On or however different people explain to do it. (Maybe with with rear left door open or the fuel door open)....and then your DSG is miraculously reset and it will behave much better This is the bit I reckon is BS My guess is you would actually need a diagnostisic tool like VagCom to reset the DSG to basic settings. As always I am happily to be proven wrong though if someone can quote a source to say this does reset the gearbox to basic settings.

Actually I will just test it myself with my VagCom and will report back, but I am highly skeptical that it will reset the adaptions.

With regard to you test runs you did, none of them were actually complete tests for the DSG7. So it may just be that by the time you had done the latter one that included the throttle to the floor with IGN OFF that all the missing items on the test checklist had actually been complete. Reversing and using tiptronic for example are required and you may have used them in the interim. So your accelerator trick may have had no bearing on the result. You could have honked the horn instead of pressing the accelerator to the floor with the keys in your lap and you may have seen the same improvement.

Assuming this Pedal to the floor to reset process is indeed an urban myth... I believe it may have evolved from a step in the fast adaption process to drive with different pedal positions. Including momentarily at 100% pedal so that the controller can recognise the value for full acceleration. Maybe the myth has grown out of that?
This requirement is similar to the way all the other actuators for gear selection and clutches must cycle so the controller can recognise and adapt to their respective end positions.

It is also possible that the mechatronic controller in some way continuously treats the required items in the fast adaption drive like a check list. So completing all items with out an actual reset via a diagnostic tool may significantly speed adaption. So there may be benefit to doing the drive sequence without doing a DSG reset, when compared to another vehicle that has not recently "seen" all the test item occur.

Cheers Logger, I'm still unsure as I can't find anything on the net about this other than this forum website. But the character of the car has distinctly changed for better and now a dream to drive.

Didn't do all that Ross Tech drive I posted. Just up the gears to 70 mph, drive at 70mph for 2 miles, then back down all the gears to 1st, coming to an absolute halt on brakes followed by a creep of about 20 feet. The acceleration section was about half throttle from the 20 - 70mph, 2nd to 7th. Same without the full throttle depression holding/ignition off had no effect.

Drove the car this morning and still it drives differently. The gear changes are seamless and you can't tell its changing unless you look at the dash indicator. It also holds 1st gear longer upto 2,000 rpm where as before it couldn't wait to get to second and always changed immediately as setting off.

Also notice that went accelerating under 1/4 throttle it holds the engine between 1,800 & 2,400 rpm in 2nd to 6th gears where are before it was much broader 1,400 - 3,000rpm.

So it be interesting to hear about your investigations as my VAGCOM PC is u/s at the moment.

The key really is what is in the VW ELSA service manuals???????
