8V VCDS Mods

Just done my first bit of VCDS modding with the 3 mods above, Needle Sweep, Lap Timer and Oil Display. All done using the Long Coding Helper as @Helifella suggested. Well chuffed :)

Now to find some more tweaks

I was watching my newly added Oil Temp on the DIS display on my way to work this morning and it's got strange behaviour, but it maybe normal?

Firstly, it only displays from 50 C?
It doesn't seem to have any link to the bar oil display in the rev counter. 90 C would already be lit and the digital reading would still be down towards the 60 C mark?
Also it seems to jump up in spurts of 5 C or so.

The highest temp I got on the way in this morning was 98 C. The bar display in the rev counter just stayed at 90C.

Is this all normal? Mines the 184 2.0 TDI.

I think you'll find the bar display is water coolant temperature, not oil.
 
as they said water temp should always stay under 90ºC, if not and without the optimun coolant it can reach boling point and evaporate. (thats bad)
while oil temperature can even reach 150ºC in some parts of the engine. but the sensor may be in some part that only reads up to 120. (drive with your engined reved up with throttle and you'll see how it gets higer)
 
The EA888 Gen 3 cylinder head design is vastly different from traditional engines, the single figure of 90 degC is not so applicable.

The thermo management of this engine is so different and advanced - the warm up time is so much quicker (and oil and water have differing warm up gradients), this is mainly due to the integrated casting of the exhaust manifold within the head.

Add to that the fully electronic coolant control system, incorporating the 2 electric motor drive rotary slide valves (no more traditional wax thermostat) and the water cooled oil cooler.

The control system actively runs the engine at 107 degC for part load scenarios (to minimise friction and gain max efficiency), and 85 degC for full load driving.

Does anyone know if these mods will use the same coding for the SQ5.
A friend of mine is wanting me to do a few things but I can't seem to find anything for it.

Cheers
 
Does anyone have the access code to change the steering weight?

Also does the A3 8V have an "eco" mode that can be enabled? I don't have dynamic select (premium) and would love to gain more fuel economy if I can.
 
For people that don't have Deadlocking on the car and want to activate it. I figured this out last night and since I couldn't find how to do it anywhere i thought I'd post it here. In central electrics long coding go to Byte 8, Bit 9 and un-tick it.
 
Hey guys, did anyone successfully disable Start/Stop system using VAGCOM?

Yea.
1. Module 19 (Can Gateway)
2. Adaption (10)
3. Go to channel: Start_stop_voltage_limit
4. Change value to 12.1V ( default is 7.6V)

I have done this and can confirm it works :thumbs up:

What's deadlocking?

It's when you lock the car from the key fob and the doors to open from the inside.

Why would you want to enable it so the car can be unlocked from the inside? Isn't that a security risk. Or is this so the car can't be unlocked from the inside when deadocking is enabled? I figured that was standard now, which is why I thought I was missing something.
 
I made it that it wouldn't unlock from the inside. In some markets it isn't standard, for example here in Egypt.
 
It's so it doesn't unlock from the inside. When u lock your car you press the lock button once and the car locks, but the doors can still be opened by pulling the handle to open the door from the inside, so if someone were to break your window they could then reach in and open the door, or if the window is open a jar they could use something like a wire coat hanger (or any similar device) to reach through the gap to open the door from inside. With deadlocking u press the lock button a second time and it dead locks the doors, so they can not be opened from inside making it that little bit more of a pain in the ar5e to get in the car to steal it.

That's great!!!

Does anyone know if i can use VCDS 12.12 with my Audi A3 Sedan 2015? I am thinking of buying one but I can't update my software to 14.10(you guys know why..)
 
Anyone managed to override the 3 sec restart delay (i.e. having to press the throttle to restart) for the ACC yet?

Okay, had some recodings done by one of Audi's mechanics at his home.

We had some trouble with the following VCDS mods:

Being able to lock your car while the engine is running (found this one on a Golf forum, but since the ECU's are very similar I thought it would work):

Enable Bit 2 under Byte 4 in Central Electronics

Doesn't work... :( If anyone would spend half an hour snooping around for this one, would be greatly appreciated.




I also did this coding (and as far as I can understand German as a Belgian combined with the Google Translate English), this coding should stop the car from dimming the LED-eyebrows when turning on your left or right indicator)
http://www.stemei.de/pages/coding/audi-a3-8v/tagfahrlicht-nicht-abdimmen.php

  1. Select STG 09 (vehicle power)
  2. STG access permissions -> Function 16
  3. Enter access code 31347
  4. STG adjustment -> Function 10
  5. Channel (10) -Leuchte2SL VLB10-dimming CD 2 Select
  6. Set value to 100
  7. Select a channel (10) -Leuchte3SL VRB21-dimming CD 3
  8. Value set to 100 (default: 30)
And the exact name of the channel we changed was
"(10)-Leuchte3SL VRB21-Dimmwert CD 3"
and
"(10)-Leuchte2SL VLB10-Dimmwert CD 2"

So that seems to be the correct one. After recoding, we tested it but couldn't notice any difference. However, when I came home I noticed that when I exit my car and my coming home lights get switched on after I open my driver door, the LED beams are fully lit (as are the xenon bulbs ofcourse). The "funny" thing is that when I lock the car with my remote and the indicator lights flash, the LED beams are dimmed continously during the blinking sequence of the indicator lights... Nice effect :p , but not what I wanted to accomplish.

There are 3 things I would lik to get done:
  • Stop the dimming of the DRL LED beams when you turn on your indicator light (always full brightness)
  • Stop the dimming of the DRL LED beams when your xenon bulbs are lit (always full brightness)
  • Full brightness for the DRL LED beams when you turn on your parking lights
So.... Who's the real "light" expert here? :D

There are SO many channels for lighting and everything, I want to understand it and found this info:
http://forums.vwvortex.com/showthre...new-to-VW)&p=86722285&viewfull=1#post86722285

Anyone care to clarify?

I am willing to share all my confirmed mods, most of them are practical and give a nice touch about lighting...
 
I already have those mods done but I don't recommend having full DRL with xenon on as they are way too bright and could annoy another drivers on the incoming direction. I have set mine to 60 and is still very noticeable at night, usually cops stare at my lights.

When I get home I'll try to translate it to English and post it here as my notepad file with the mods is in Spanish.

PD: parking lights are? I'm still a bit confused by that term.

Agreed. Mine are at 50% dim during indicator (default is 30%). As are my side/parking lights.

We've had this debate many times before. It's not a good idea for DRL's and side/parking to be at 100% at all times.

It's against the EU directive to not dim during indicator, and the brightness of the 8V DRL is such that oncoming cars can't see the indicator on the non-combined DRL/Indicator option.

The LED indicators on the door mirror are angled for max intensity when viewed from the side of the car. As you move round to the front, they progressively get dimmer.

So in sunlight you would not necessarily see those when viewed from the front.

Why would you increase the risk of an accident by making it more difficult for oncoming traffic to see your indicators ?

Ok, I have read the advice and taken it into consideration, but still want to try it to see how it looks. Is it ok if we stop the debate about why's and why shouldn'ts? (nofi)


@ChiYoung : thanks, very eager to get your notepad.
Parking lights are those lights

Copy%20of%20IMG355.jpg


When putting the dial on this, your LED beams stay on when you park your car during the night on a small road in a small village or wherever... ;) (the image is just a reference for showing you the green icon)
 
^ Technically - that is the sidelights position.

Although really, no-one should be driving around with just those lights, hence they get used as parking lights.

Parking Lights are when you have parked up - and put the indicator stalk in either the Left or Right position - this will bring on the corresponding low-level Parking Light - which is used when parking on the pavement or in the street - switch on whichever light is closest to the the centre of the road - and it will bring on the front and rear low level light on one side of the car only.

It's not really the ethos of this forum to restrict free speech (within limits) and opinion, so I'm afraid you're going to have to take the rough with the smooth :)

Everyone on this forum is entitled to a view, not really into the whole censorship thing :)
 
Ok, then we're on the same line :D

But with Xenon and accompanying LED eyebrows, the LED eyebrows are the lights used as parking lights. Or do you mean "dimmed" with "low-level"?

Because of the clarification with sidelights vs parking lights I now have to make the list as follows :D

  • Stop the dimming of the DRL LED beams when you turn on your indicator light (always full brightness)
  • Stop the dimming of the DRL LED beams when your xenon bulbs are lit (always full brightness)
  • Full brightness for the DRL LED beams when you turn on your sidelights
  • Full brightness for the DRL LED beams when you turn on your left or right parking light

Really, any help would be greatly appreciated.

They are all the same, you just have to try different letters like CD, AB, or GH...
In this case it may be CD, and if you see the Leuchte part has numbers like 30, its the dimming %.

In my case I also have 100% LDR while coming/leaving home and I don't know the parking lights but they are also bright like the 60% I said earlier.
Its just a matter of trying inside the ones that have value 30%.

PD: Its very important that you dont set the Leuchte AB ones to 100% as you may blind drivers but I'm sure you will test and see it for yourself.
 
What I don't get is why anyone should want to stop the dimming of the DRL LEDs when the indicators are used. There are enough cars around where the indicators are not easy to see with out making the whole situation worse. Audi have developed a good system that dims the LED DRLs so that the indicators show up well to other road users, why would anyone possibly want to change it.

I don't get wanting to stop the dimming full stop. The whole point of them dimming is that at night time the LEDs are too bright and can dazzle. They have to be bright to be visible enough in daylight.

Another case of someone who thinks their ability to do what they want with their car overrides the rights and safety of other road users.

Hey there, new to the forum but have been stalking around for a bit!
I'm doing some mods tomorrow and was wondering if anyone knows if there is a mod for CH/LH lights for cars that didn't have it as an option when built?
Had a look through here but can't seem to find one...​
 
Yes they have to flash the high beam lights once before exiting the car.
I don't know if theres any leaving home but the coming home works like that.
You have to set this coding.
Coming/Leaving Home manual
STG 09
Access code 31347
Adaptation
(1)-Comfort illumination-Comming Home Verbaustatus -> Manual.
(3)-Comfort illumination Manueeistellung -> set time in seconds. Range from 0 to 90 (?)
Before leaving the car flash the high beams once.
 
Thanks for that! Will try that out tomorrow.
Do you know if that turns the lights on when I unlock the car or if it requires another code?

I have no idea. I think it only works when you get out of the car (Coming Home).
No leaving home function in this manual mode IMO.

I am pretty sure Needle Sweep is as above. But for some reason when i press "Do It", it showed me an error code something like "FFFFF5" Unknown Error or something.
Not sure if its because i am using an older version (12.12.0) But i was using a cable from ebay so unable to update..
 
I don't know what the coding was, but I have needle sweep activated on mine, so it works.
 
Does anyone know the coding to apply for retrofitting a towbar? Got one retrofitted but would quite like the parking sensors to deactivate when its all hooked up.
