Thank  you Tech...i'll check right now !!! 

Hello everybody !!!!



I have
a problem with my wife's car:  audi a4 (b6) 2003 1.9 tdi 130 hp, RHD



Last
week after a very heavy rain in London, my wife told me some water leaked
inside the car around the acceleration pedal area.



When
she put the ignition on next day she heard a strange noise like an electrical
short and the wipers started working fast without any command :D ....she
couldn't stop them...then they stopped on their own and then wouldn't start on
command. Now they seem not to be working at all, they start randomly working
without comand and then stop.



I am
trying to identify the issue



I read
almost all forums about this problem, and  am sure that: 

1.the
linkage is not seized, it's moving free and working very fast.

2. the
switch is probably functional because the windscreen washer and the bord
computer are working

3. I
read about some wiper relay no 377....but on my model i don't have this relay
.i looked all over the car to find it ...

4. the
wiper motor i think is ok because i checked another 2 and none is working...so
i measured the connector that supplies the wiper motor and I have a live
12v in pin nr 2 and that's it and some one told i must have life in 3 pins .



So my
local garages told me: Ecu is dead because of water lick but i check the ecu
compartment and everything is dry and clean there,Ccu is dead and need recoded
for audi...and audi specialist told can be some relays located in back of
steering wheel....



After
diagnosis with a bosch software was found it 15 errors ...but the most
important was : can't communicate with Conventional Control Unit...wiper motor
stage 1... control unit...wiper motor stage 2 ...



Some
errors wasn't true...but was erased. 





Anyone
have some ideas about how to fix this problem without spending thousands ?
