Need info re OBD11 upgrades for 2018 Q5 prem+

[greasykid]

Next week going to have tech do upgrades w/OBD11. Really appreciate a listing from anyone who has a list(s) of recommended mods/upgrades etc.for my 2018 Q5. Pls post, pm or email me. [email protected]
Want to get it done right the first time. Have done a forums search but sure my findings are not complete. THX

Take a look at this thread in the B9 A4 forum, most of those will work in the Q5

I used the OBDEleven app for 10 credits. Following are the changes made at a bit level which I believe you can make using long coding.
09 Central Electrics
Long coding:
OLD

36 Seat Adjustment Driver Side

Adjust MPG Calculator
Dash Board (17)
Adaptation
Display correction of consumption and operating range
Changed from 100% to 107%

Change AC Option from AC Max to AC Eco
Air Conditioning (08)
Adaptation: ACmax/ECO
Old Value: ACmax
New Value: ECO

Adjust Volume Defaults
Control Unit 5F
Adaptation
Audio Management Input Gain Generation 2
Satellite Radio - old: 17 new: -128
Radio (AM): -5
Radio (FM): -5
Satellite radio: -2

I tried the app on obd11 for this but it's not doing anything. I see the bit to modify for module 19 but module 36 isn't labeled. Do you know which bits need to be checked for byte 3 and 6 in module 36?

[spindlewood]

First, go into the MMI and search for the seat adjustment. I'm pretty sure this mod adds a setting which wasn't visible before. You might have to uncheck and recheck the setting for it to take effect. I remember I had to do this once.

Also, did you take a backup before running the app? If so (and even if not), do a backup now and generate a current file and send it to yourself. Compare the two files and see if the changes shown in the post for 09 and 36 were made by the app. Presuming not, this is the logic I'd follow, using my experience as a programmer. But I haven't tried to do this mod using long coding myself and so you do this at your own risk. Remember to make a scan and send it as a backup. That said...

It appears that each two places (of numbers or letters) in the long coding string represent a hexadecimal digit.
Each hexadecimal digit represents four bits, or half a byte.
So it takes two hexadecimal digits (4 places in the long string) for each byte.

If we take 36 Seat Adjustment string and split it byte by byte we get:
005C 1B00 0000 B001 0000010101010000000000000000000000000000000000

It would appear that it is bytes 2 and 4 that need to be modified.

If you go this route, make sure you run a scan and email yourself the file and then after the change do the same thing. Then verify that the changes show up in the bytes you expected. If not, you can easily go back and reverse your changes.

If you do attempt this, please report back with your results. A pic of the screen where you've made the change would be a bonus.

Good Luck!

When I reconnected to the car the app did in fact modify those two chains. I'll try and dig through the MMI for the seat settings.


Edit: Off and on in the MMI was the trick. Disappointed that it only goes back and not down, I was hoping it would be a hack for my squeaky seat. It was already re-greased once...

It would really help if you would put the model and year of your car. Someone with the same car may be able to help you out. As for the squeak, there's a TSB on newer cars regarding bad welds inside the seats. May be causing your squeak. Sorry I don't have a copy of the TSB.

It's a B9 SQ5, but not a driveline issue, so it should generally apply in this forum. I'll check out the TSB about the welds, the only one I found was to grease the tracks.
