Weird noise from PAS

[dncj]

Hi

I´ve seen a lot of PAS an FLickering light threads but mine seems a bit diferent.

A hear a strange noise(like a pump trying to work but very briefly,not the common electrical sound) coming from streering pump ramdomly even when the car is stoped and not moving the steering wheel,and when i hear that noise the lights flicker( not diming but just a quick flicker ) incluiding the dashboard lights.

I notice the steering is a bit harder sometimes but nothing to heavy (ideal on my opinion) and sometimes it seems to be very light too light

From the threads i´ve seen it supose to be the PAS angle sensor but no steering light on dashboard and no errors on vag-com(version 3.2)...

i´ve checked group 1,2 and 4 on the Pas module and they seem fine the value on the sensor doesn move when the car is stoped...The skoda dealer doesnt find anything wrong:rotz:

The liquid seems fine and batery was bought last year

Maybe the PAS PUMP?Isn´t it supose to be an error on the vagcom?

ANy ideas?

Very greatful if someone give sugestions

Thx a lot (sorry for the english:O)

My first guess would still be the PAS angle sensor with those symptoms

thks for your reply

Dont u think that if the sensor is faulty it should be an error on vagcom?

Like Yegnold said, I think this is the sensor to.

No dash lights could be because it's a very quick intermittent fault at the minute and not long enough to log.

If your getting pump noise when the wheels aren't moving it does suggest the pumps getting incorrect messages from the sensor and adjusting for non existent movements. I'm not a mechanic though, so don't quote me.

how old is your car? Is it from the first few years of production before this part was revised?
