Title: After bench flash no start Post by: ratherb1 on February 10, 2014, 03:30:13 PM So I bought an ecu 4b0 907 551 t ( 2001 audi a6 ) about a week ago ...and after flash via galletto there is no start just crank and cranks ......( flashing s4 file ) .i did leave the key on position for like 1-2 minutes and tried again but no go .....so just 2 quick questions
1) after galletto writes 100% should I just ignore the commands ( don't know what they say) and keep continuing? 2) is there something else I need to after I install newly flashed ecu?

Try that, it should come back to life.

Try that, it should come back to life. We'll the ecu I got is the same part number as mine .....(4b0 907 551 t).....I'm using an L box (s4 flash) for my t box 2001 a6 tip ..... So I galletto flash, disconnect, go to car install, and car just cranks Sorry if I misunderstood but what do you want me to try ? Title: Re: After bench flash no start Post by: ddillenger on February 10, 2014, 04:14:59 PM You are putting L-box software on an A6 551T....
That is the very definition of changing software :( Bootmode flash it. Title: Re: After bench flash no start Post by: ratherb1 on February 10, 2014, 06:52:22 PM I am boot mode flashing ......using galletto , maybe I'll try to flash back a stock file an immo off it
Title: Re: After bench flash no start Post by: ddillenger on February 10, 2014, 06:53:50 PM Does the ecu have a stock chip? Can you connect with VCDS?
Title: Re: After bench flash no start Post by: ratherb1 on February 10, 2014, 07:22:02 PM Yes stock .....

Title: Re: After bench flash no start Post by: ratherb1 on February 12, 2014, 07:32:08 PM the command at the end of galletto says turn key off for 10 sec I don't have a key since it's on a bench .....all I did was hit okay waited and turned the power supply off ..... Idk I'll try an ori file and immo off it see if that works |
