Servo steering

[Torbo]

In the last I have had some problems with my Fabia 1,4 68 hk - 2000 model. 

The servo light came on. I fillet up with oil, but it came back. I changed at rusty high-pressure tube from pump to servo unit. 

It has worked for some time, but the light came on again, and the servo power was zero. 

Hard steering for some miles. I stopper and waiter a litle an the lamp get off, and the power was good.

I will out driving no, to if these happens again?

Read abut some contact problems to the servo motor?

Is i a idea to take the servo out and look?

Might be the steering angle sensor at the bottom of the column.

 

Any fault codes?

Sounds more like water ingress into the pump ECU, it's impossible to stop, particularly in a cold climate like Norway.

There is no fault codes. I can cheek the level again? I have not check since i change the pressure tube.

Of the record : I made a big hole in corner of the batteybox, so it is more easy to check. 

And a little backup battery to the lighter plug so the radio codes a.s. don't went avay.

Do you know exact where the censor i placed? May be I can clean it up? 

 

It happened on icy roads in high speed, may be some ice and water can make trouble ? There was also salt and small stones on the road.

ECU is built into the pump housing so when it get cold overnight, water condenses and runs onto the PCB, the sensor is sealed and would give a fault code if faulty.

Have you checked the fuse strips on top of the battery? They can develop hairline cracks and become intermittent.

The pic is just an example.

 

Fabia power steering fuse is usually 50 amps.

Snowing here too.

To day I should go out and look at the fuses! But then the snow came again! 

Bu now I know the logic - if it is cold the fuse can be open because the metal shrinks in cold..

May be fix it tomorrow.
