Combining combos: how to avoid conflicts

Several combos that control the same function work against each other: the lights flip back and forth, announcements come twice, an exception gets overridden. That's why the collection assigns every combo to a conflict group. This guide explains how the groups work and how to check your selection.

Why combos overwrite each other

Every active combo runs its actions as soon as its trigger occurs – regardless of what other combos do. If two combos control the same function by different rules, the one that runs last wins. Lighting shows this well: 8205 0005 switches to side lights in D and R during the day, low beam in the dark and everything off in P. 4470 0020, on the other hand, leaves only the parking lights on when you get in while in P. Together they give contradictory lighting commands.

Conflict groups in the collection

Combos that control the same function are in the same conflict group. For each group the collection states how many combos make sense at once – usually one. You'll find the overview of groups on the code page, and every combo names its group on its own page.

Two combos per group are allowed where they complement rather than overwrite each other:

Mirrors on entry: 6058 0042 (at home) and 6499 0048 (away from home) are meant as a pair; 5361 0036 shouldn't be added on top.
Seat heating on entry: 1809 0021 for the driver and 9600 0018 for the passenger.
Massage when buckling up: 2675 0020 and 7088 0016; continuous massage: 3598 0041 and 8960 0051 – driver and passenger each.
Welcome announcement: one greeting for you and one for the children can be combined.

Typical conflicts

Heating and climate by outside temperature: nine combos control heating, steering-wheel and seat heating or climate – for example 4671 0053, 5863 0042 and 8512 0018. Keep just one. Don't combine the seat-heating combos on entry with climate automations that also control seat heating.
Sentry: a combo without a home exception overrides the exception of another one. If you use 9313 0040 (Sentry except at home) together with 5502 0032 (Sentry as soon as the car is locked and off), Sentry will be on at home too.
Locking: 4302 0029 doesn't lock while someone is still inside – which contradicts combos like 2174 0034 that lock automatically after a few seconds.
The same combo under different codes: 6322 0009, 9015 0005 and 1447 0005 are three identical variants. One is enough.
Volume: seven combos set the volume differently when you get in or open a door. Several of them at once lead to fluctuating volume.

Counterparts that belong together

Some combos aren't competitors but two halves of one idea. They aren't in the same conflict group and should be used together:

1016 0001 moves the driver seat back before you get in, 7272 0001 then moves it to your driving position.
2136 0055 turns off X-Pedal when you arrive home, 7205 0054 turns it back on when you leave.
4237 0000 demists the windscreen, rear window and mirrors at the push of a button, 7157 0002 stops defogging when you get in.
2427 0028 sends the driver “I need you”, 6114 0030 the all-clear.
4871 0019 ends car wash mode after a car wash combo.

How to check your selection on this site

Mark the combos you use with “I use this”. The “My combos” panel on the code page then shows whether more combos are marked in a group than make sense – affected combos get a “Conflict” badge. Your selection is only stored in your browser.

Rules of thumb

One combo per conflict group – except for the pairs that are explicitly allowed.
Before activating a new combo, check its group and what you already use there.
If a setting changes unexpectedly, deactivate your combos one by one until you find the cause.
Test new combinations while parked.
