Hi,

 

I've finally managed to get vcds-lite to talk to the Mrs' 6Y Fabia, and it's reporting:

 

Address 44: Steering Assist       Labels: 6Q0-423-156.LBL

   Controller: 6Q0 423 156 E

   Component: Lenkhilfe           0001

   Coding: 00110

   Shop #: WSC 00000

1 Fault Found:

00816 - Power Steering Sensor (G250)

            37-10 - Faulty - Intermittent

 

Is it therefore pretty likely that the sensor is at fault? If so, is it easily accessed/replaced?

 

I'm still chasing down the flickering electrics issue, so I'd like to get to the bottom of that before assuming that any other electronics are duff.

 

Cheers,

Iain

Have a look here http://wiki.ross-tech.com/wiki/index.php/00816

 

You'd need to put the car on ramps or axle stands to get to the sensor.

 

The sensor fits into the rack and is item 10 or 6 here depending on type....

 

Two torx head screws to remove, access from drivers side wheel arch (wheel off), then one very long cable with no joins from sensor along subframe/rack to passenger side then along chassis rail to under battery/screen wash bottle area, keep sensor intact & use for rebate as I got circa £30 for it from the dealers. Clipping the wiring back in place etc is very time consuming & fiddly to get the route correct!!!

 

I have done two of these & a PITA!!!

The flickering is very likely to be caused by the dodgy sensor making the steering pump run when it shouldn't.

Cool, thanks Wishing I still had my lockup with 4-post ramp now!

Ah, that's an interesting thought. I'll see what happens

Out of interest, is there any reason why one shouldn't cut and join the sensor cable rather than re-routing it, provided it's properly done and waterproofed?

 

Or is it just as easy to do it properly?

It's just as easy to do properly.

I'd say it would be harder cutting and joining it.

Have you had a look yet? Depending on what year the car is, it may be the much easier sensor with connector, rather than sensor with captive cable.

Not had chance yet. I'll take a look this weekend

Got the sensor changed yesterday (thanks to steveopc for sorting me out with one). Not a bad job at all, really.

 

So far, so good. No sign of the steering fault light, and the electrics seem to be flicker-free. Hopefully that's the end of that particular gremlin!

 

Thanks again for the replies!

Hi

Can I ask, what was the initial problems with the steering?

My fabia has recently suffered occasional stuff steering. Just for a brief second then returns to normal. No warning lights on etc.

Opposite with mine. Warning light would come on after ~10 mins of driving. Only occasional assistance loss, notably when parking.

 

Cheers,

Iain
