VAG 16955 - Brake Light Switch (F): Implausible Signal - intractable problem

[adulka]

hi,
sorry for my bad english, i am not from UK

i have big intractable problem
my EPC still shinning

on VAG is error: 16955 Brake Light Switch (F): Implausible Signal

i am looking on internet, ross tech, everywhere but problem is intractable

i had made:
i check connector - i think is ok, I "measured" 11,89 V (this is ok, think)
i replaced new Fuse
Replace ALL new Brake Light Bulbs
Replace NEW Brake Switch

after all i deleted error on VAG
but EPC is still shinnig ...

one detail: when I go long time without braking then EPC is off, but after stepping on the brake pedal EPC is shining again

i dont know, where can be still mistake ...
can someone help me?

thx Adam

hey problem fitted

here u have a "guide"
sry i havent english VAG, but perhaps it will be comprehensibly

go in to VAG -> ENGINE -> MEAS. BLOCK -> GROUP 066
in second "box" u MUST have 0000 like here on image, u MUST NOT feet on the pedal, if u have somewhere 1 ist something wrong

What do the numbers
0100
"clutch" pedal is pressed

0011
brake pedal is pressed
this first 1 is for "blue switch" and this second 1 ist for second "white" swtich
i had BAD CONTACT on SWITCH, try check conntact

0111
clutch + brake pedal are pressed

coil prob/limp mode

hi i recently had a coil go and i changed it,two days later i was in boost at about 3500rpm and the turbo dumped as if id taken my foot off the accelerater?the car has been in limp mode since(if boosting at 5psi and no more is limp mode)i checked all pipes and everything seems fine,is the only way to check this with a VAG COM?i bought the other 3 coils today and am waiting to fit them,although i dont think this will make a difference?and has this happened anyone else after they changed a coil?or if anyone has any suggestions id be very grateful thanks!
