Audi Mod

[Bsoul38]

Hi all! I have just recently done the "Audi Mod" via obdeleven. Was just wondering if there was anyone on here that has had it activated long term? Any concerns or issues?

Thanks!

Have been using it for almost a year with no issues. It suits the car so much better.

Yea it definitely makes the car so much better. I just can't help but feel there should be a supporting mod for the gear box to go with the engine module mod. Maybe I am just over thinking things.

Hi,
Can you explain "Audi Mod".
Cannot locate anything like that on my obdeleven.

Cheers.

Just changing the engine code from "vw/skoda" to Audi. Only way to do it is through the long coding section of the obd11. Do a little bit of reading on it and If you are interested I can walk you through it.

Cheers.
I will look it up.

This is how you do it with VCDS. It would be similar or in the same area for OBDII

Hey mate, how long have you had it on your car now? Any issues at service time?

It'll be 2yrs this Jan since I've had it. I basically did it within weeks of taking delivery of the car. No problems at all during service.

what exactly does the mod do ?

[oldstuff]

Just some advise from those who have done the mod, generally I would expect there is something given in return for improved responsiveness. Is there any increase in fuel consumption or any other noticeable differences ?

OBDEleven arrived this afternoon, so going to give this a try.

I haven't done any long coding before, but it doesn't sound too scary.

Made the change today. Did a full backup and cleared faults first, took it for a test drive and all seems good so far.


The throttle response is improved, kind of like going from a wet Sheep-dog to a dry Labrador. Bigger difference in sports mode - much nicer.


Looking forward the the stage 1 tune - hopefully we can get the throttle response of a Greyhound out of the gate
It still handles a bit like a washing machine, with the odd suspension rattle or creak. Looking into a stage 2 suspension upgrade too.

It also seems from that short drive the fuel economy has improved. Has anyone else noticed this? I'll do some more testing and report back.

Here's my coding from OBDEleven, it took me a minute to realize that it was little-endian binary (vs big-endian in the VCDS screens hot that I was working from).

(edit) Access this under: Arteon/control units/ engine/ long coding / byte 0, untick bit 0 and tick bit 1. The result should look like this:

Like in your other post about it you havent said WHICH MODULE you are doing it in. No good just posting a screenshot without the full information as to the path to get to that.

EG Arteon/control units/ engine/ long coding / byte 0 tick bits 1 and 3

In my iteration it actually has VW in bit 0 and AUDI in bit 3 on that screen

Sorry, my bad. Will edit that once I'm back in front of a desktop (edit doesn't seem to work on my mobile browser, just wipes the whole post).


AFAIK - it's just the first 3 bits (0-2) that configure the engine manufacturer setting. Little-endian: 100 (decimal 1) is VW/Skoda and 010 (decimal 2) is Audi. Bit 3 would be part of the body type setting (bits 3-5) and the rest of the bits in the first byte are for market: set to Europe / rest of world (RoW).

Here's the VCDS screenshot I was working with. Just reverse the bits as it's big-endian. The hex stays the same (09: VW | Sedan | RoW, 0A: Audi | Sedan | RoW):



So putting it all together, coding with manufacturer VW is 10010000 (decimal 9 or hex 09) and if you set the manufacturer to Audi, you get 01010000 (decimal 10 or hex 0A). Bits 3-7 remain unchanged: Sedan | RoW

I hope this makes sense?
