Title: Cluster 8L0920931F - Tuning in eeprom (needles&scales) Post by: vara82 on November 24, 2017, 02:07:38 AM Hey Guys...
Is it possible to switch on Lights from needles and/or scales with turning on ignition by changing some bits in eeprom?! Perhaps it´s possible that needles going up&down (initializing) when tunring on ignition?! I know from various Golf 4 cluster that i have to change one bit in the eeprom to turn on lights, welcome message and so on... I´ve a Cluster from Audi A3 2002, too... There i can switch on the lights over diagnostics Channel 19... But at actual cluster Channel 19 doesn´t exist. It´s a 8L0920931F (VDO) from a 2000 Audi A3 1.8t. Dump from Cluster attached...

On your 2000 cluster you can only set to light the scales and needles together on ignition , with or without switches. The adres you are looking for is $1DE- the default od 35 , you should try changing the second position like 3D , 31 etc Title: Re: Cluster 8L0920931F - Tuning in eeprom (needles&scales) Post by: vara82 on November 24, 2017, 10:55:02 AM Hey macxxx,
thanks for your help... It´s okay for me if it´s possible to light up Scales and Needles together with ignition... But i can´t found the default value (35) in 1ED location... Please take a look at the picture i attached... Can you please mark the location i´ve to change?!

Have i to correct checksums before flashing the file back to cluster?! Or can i change the file and flash it without any corrections without cluster is damaged?

here´s my report: 3D is the solution... I tried a little wirh another digits but it won´t happen so much... With "3D" at "1DE" Scales, Displays and Needles light up with ignition. Perfect, much thanks for your help!!! |
