C99 reported (http://www.a5oc.com/forums/showthread.php/check-oil-2909/index.html?p=32223) in an A5OC.com thread how you can access a hidden maintenance menu via MMI.
(This may require the "real" MMI 2G, it may not work on a Concert/Symphony radio and MMI 3G hidden menu is enabled differently, see below. See here for more on the "real" MMI vs. radios: http://a6retrofit.tripod.com/articles/a4a5realmmi.html).
Apparently you can access this hidden menu by holding down CAR and SETUP for five/six seconds.
There are whole host of settings you can access here, like adjusting MMI timings, visible options - apparently you can even adjust the TV blackout speed or remove it. I hear you can also make CAR menu selections appear without speed limit.
WARNING! According to reports don't select "Bootloader", it will lock the system in a software update mode without a way out (http://www.a5oc.com/forums/showthread.php/interesting-VAG-COM-3442/index.html?p=38153)...
Some general info on the same/similar hidden menu in A6 is here: http://www.motor-talk.de/forum/aktion/Attachment.html?attachmentId=397283&ajax=true .
If this menu doesn’t work and your MMI version is up to date, you need to enable the menu with the following VAG-COM steps: Head unit controller (07), Adaptation, Channel 8, change 0 to 1, Save.
車子有3個地方 出現故障碼!
分別是: 56收音機 17儀表 46中央舒適系統
以VAG-COM 清除故障碼後,發現2個問題~
1. B8 好像沒有防盜系統!? 勾選任何一項防盜,都會再度出現故障碼!
2. VAG-COM打開胎壓監控,清除故障碼後, 音響CAR的螢幕選項有3個要停車才可以使用!
分別是parking, tire pressure monitoring, wiper
只有停下來, 才可以進入選單!
請問有改過的大大有碰到一樣的問題嗎??
後來再掃一次, 把防盜系統整個關掉就沒出現故障碼!
胎壓監控 進入後有個 "儲存", 必須停車,才可以進入!
不知道會不會影響功能??
請開釋~~~~
