audi a2 elettroguida does not work

[domy_pikkio]

good afternoon colleagues..now I describe everything I get in my workshop the car listed above from other workshops anyway we go to so this car does not work the power steering ch I ch ? electric in the past few days have replaced two pumps electric without riolvere the problem comes to me I am a customer telling me nn c'? I do more? we have replaced two pumps(used) but the steering is always hard, and after that have been replaced tells me we have tried to configure them but instead of solving the whole ? out another problem remains turned on, abs warning light and warning light hand brake ? in alarm sounds while you walk.I begin to make the diagnosis, but in the electric steering I nn f? enter controlled power supplies pump ok then I encountered the following errors when I made the diagnosis all systems them to the list:command data bus missing communication from the abs-ecu ports 8057,signal cresch from the ecu is not plausible,the control unit for power steering-j500 1309,sensor power-steering-g250 0816,operation, support steering 0566, opening signal impatto1366..these are the dtc found I ch the car has had a long time ago in an accident but without finding any fault ...now I find myself here at nn know ch do hard steering and abs warning light on where to start????..any advice is accepted thank you and welcome you domy : Andry :

in which ecu you have found? all abs?

in which ecu you have found? all abs?

in several abs ecu electric steering and airbags, I ch, in the diagnosis x every single ecu nn enters the steering

hello,first thing, are you sure that the old pumps work?? I would check your electric pump if faulty,or to try including the ecu, I always speak revised, at least I have a friend that allows me to do these tests,would check the sensor, which is located near the box guide,such as audi A3 and skoda, I have solved it many times so,if l plant l have you checked the masses and positive are OK I would do so!!

Hello, I will tell you mine: I had just been playing with the CdB, I had turned on the lamp of the "esp" steering and... there it was to fix it.... I unplugged for 10 minutes the battery, I reconnected and after 100 metres of the road have disappeared from their errors. Test

An alignment of the network, have you tried it?

hello, I am sure if you are working for? can't believe ch in the middle of three nn it works???then this sensor nn c'? on the steering gear..then if ? the sensor cm never nn enters the diagnosis?

hello alignment in which ecu do I do that?and how? the texa does

good day to all, how do I see if it works the the can line I ch I oscilloscope..

I have to say that with an oscilloscope, you would see only the Hardware protocol, while there is a logic state analyzers that make us?. But according to me, without spending money, I think that if the vag-com does not work you do not have communication with the can. But have you tried to do what I recommended before?
Then I really don't see the logical connection to the fact that replacing the pump is not working + communication with the ABS control unit, as I SUPPOSE that the pumps are the actuators, while the control unit that the pilot ? the same which communicates with the can.

you cmq I tried the control unit, nn is in the pump sorry..and then abs and the engine management comes and then what? the problem?

[Fedex]

Buond?,
Sorry I did not mean ABS power steering but that should be the steering or the like. Sorry again, I had a moment, confused :(

[giama'a]

but the pumps replace are the same comparison?

[domy_pikkio]

but I have this pump, I can try over the counter?

[Fedex]

[domy_pikkio]

not even I would expect any lighting from you, and you instead?

[giama'a]

as said before, checked the reference no. of pumps

[alex68]

have you tried to make a diagnosis with VCDS if not go with the one you have power supply problems,
