Fabia power steering problems?


Tech1e

Recommended Posts

What I forgot to mention (which is my biggest concern) is this wiring on the battery fuse box.

Obviously somebody was messing with the electrical installation, as the alternator cable is placed one place to the right, and everything else shifted. My concern is should the alternator cable be connected to a 110amp "socket" rather than the 175amp that is factory made. Should I switch it back, and if I do so - will I burn something or cause more trouble? A cousin of mine got lights flickering and PAS issues, same as mine. He bought a second hand fuse box and replaced it. Didn't have any issues ever since!

 

 

Flickering as been know to be caused by a faulty sensor.

If you have vcds check measure block 02.1 on the PAs module (44).

That should be always 0 when you are not moving the steering.

Replacing the rack on my Fabia this weekend with a used spare (and pump if it turns out my spare rack isn't right for the pump), does the PAS system need bleeding after the rack is replaced it does it sort its self out? If the former, any ideas how? Thanks :)

Thanks for this extremely useful forum since we all own a crappy car  

 

I've had the same problem as you all. The warning light started to light up occasinally and after some time is was permanent and the steering became wery Heavy, no PAS at all. The steering angle sensor was not the problem, ni flickering lights. This was replaced earlier with and the car har all the symptoms. Anyhow it was checked again without any problem.

I dismantle the PAS pump (I can sincerely recommend to do this via left front wheel, the connectors are a hassle but you will end up breaking some of the plastic fasteners for the front bumper and this do not improve your car's look.) and stripped the Electronics open. Could not find any obvious error. I had the pump open for a day or something, trying to overcome my emotions about spending 350 EUR for this **** car valid 500.

I then pulled myself together and mounted the pump to try it out again and, voila, it worked  

The silicone, sealing the Electronics was not perfect and i guess the electrics got damp/wet and drying it out did the wonder.

Turn it 10 times max left and right, start Engine and do the same. Fill up fluid as you go.

The pump is crap... check this...

Interesting stuff. Is that an old pump of yours that you're emptying there dm222?

Is it clear where the water entered?

 

I bought another pump on ebay this week, I'm not having good luck with used pumps, this was the second, the first arrived damaged months ago, it was one last thing I wanted to try because the steering did not get better after all this time. Although I believe it improving a little bit with the time.

 

it's not clear how the water got in, there is no damage, the silicone seems OK, the pump is from 2015, only 1 year, the pump was properly sealed. It came with the connectors and cables still in place (cutted) so water couldn't got inside though there, but once I removed them I saw a little water inside the main plug, and inside the one that goes to the sensor, pic below,  so I removed the plastic thing (not recommended unless the pump is for scrap) and came with this surprise. Water was probably inside for a long time since it has a lot of rust.

 

This was only like 1/3 of the water it had inside, because I removed a lot before though the two holes in the middle.

I suspect water gets inside below the plastic thing... there is rust there the one on the right so water got there at some point for sure.

I wanted to open the pump to study it but I have no idea how I can remove the case???

Thanks, very strange that such a young pump leaked so badly, I guess we can't conclude that it came in via the connectors, because it may have travelled to you the other way up; but it does seem like a possibility. Do the two holes in the square corners of the two-way connector go right inside?

No I don't think it came in thought the connectors. 

No but the ones on the middle do, the other two in the square corners don't, they had water because I removed thought the ones in the middle and got there.

Exactly since it came the other way up the water came from inside to the connectors, I removed a lot of water that way before removing the plastic.

 

I believe it was here, hope you can see that layer of rust/dirty there, shouldn't be there at all since it is sealed by rubber.

 

PS: I'm speculating.

Now, I don't know how the fabia is but the Ibiza gets a lot of water there when washing the car or it rains.... (a lot worse when washing) If it's not porperly sealed......

Inspecting this pump I think I remember my return connection on the reservoir not being like this.... it was something like this, is this possible? At the time I didn't care, thought it was suppose to be like that...They are both exacly the same part number, including the letter on the end.

 

I will remove the return line for further inspection.

Hi all,

 

 

The mrs' 2005 vRS suddenly started with a power steering issue yesterday.... I don't drive it very often myself but when I did a couple of weeks ago I thought the steering was slightly heavier than normal but put it down to me being used to my own in the Superb etc...

 

Anyway just as the wife arrived home yesterday afternoon she said the power steering warning light lit up and the car starting "binging" at her. She turned off the car and then turned it back on and restarted it and the warning light didn't light up but the power steering was still not working.

 

I tried again when I got home and still the same no warning light on the dash but no power steering either.

 

Anyone any advise... I'll check fuses tonight or tomorrow night when I get home but I'm assuming that would give the warning light all the time though?

 

 

Just confusing that the warning light isn't lighting up after that initial time but the power steering is as dead as a dodo....

Well checked the two fuses ok and also the battery this evening (Approx 11.93v everything off.... Approx 9.8v while engine was cranked up..... Approx 14.39v when engine running) So unfortunately the easy options are out. :(

 

Didn't have time to see if my OBD dongle and Carista app could see any codes as it started getting dark so will have to try that over the next day or so then off down to the local specialist to confirm the damage. :(

'ello, thought I'd chip in to this topic.

 

A couple of months back I had a flat battery, a couple of days after having a new battery fitted (not holding good charge, had run flat a couple of times, nothing else at fault), my PAS light came on after pulling out of a spot with full lock on. Engine off and on cleared the light and some assistance returned, enough to get home. Dealership said it was probably the low battery, just keep an eye.

 

I had heavy steering the next month or so but didnt rush in because it was booked in for a service, dealership can remain anon on this one. Had them give it a once over while it was in. They quoted £700~ for a replacement pump £900~ inc. labour - they couldnt give a proper quote as their network was down.

 

Took it home unhappy about the pending bill but wasn't convinced by their diagnosis. I kept wondering about steering angle sensor, fluid level etc. as something just felt off with their diagnosis and I wasn't convinced without ruling things out myself.

 

Plugged her into VCDS and looked at errors on PAS - one logged 'low voltage, function restricted' which I figure will have been from battery-gate. Cleared error. INSTANTLY on starting the engine, full PAS returned, not a problem in over a week now having driven daily. Fingers crossed its all good now.

 

I presume the low voltage error code still being logged had put the PAS in some sort of failsafe mode with limited assistance. Im not au fait with the details, but it makes sense from what i experienced.

 

I hope this information helps someone else avoid a ~£1k bill from a dealer!

 

EDIT:

For information, if its any use, here is the log:

1 Fault Found:
13893632 - Function Restricted due to Insufficient Voltage
          U1400 00 [008] - -
          Intermittent - Confirmed - Tested Since Memory Clear
             Freeze Frame:
                    Fault Status: 00000001
                    Fault Priority: 6

                    Mileage: 28217 km
                    Date: 2060.14.17
                    Time: 18:54:43

Apart from the obvious details - the date is rather interesting....anyone any insight on their datetime format? The year is bad enough but 14/17? lol

Just read all this...

 

Im having issues ... i have abs/ powersteering and Traction warning lights on dash, when i try to clear the codes they are instantly back on. The powersteering works intermittently even though the warning light stays on, actually the powersteering works most of the time. And really only seems to not work at low revs or idle.

 

I will post up the fault codes later, i need to check again. Battery was changed 3 months ago.

Started the car (2010 Fabia 1.4 Tdi) this evening & the orange steering warning light came on the dash & the power steering wasnt working. 

I didnt move the car at all. Switched ignition off & started the car again & all was ok

 

Ill try & connect VCDS tomorrow evening to see what fault codes are stored

 

I had a quick look under the engine bay to check the fuses on top of the battery cover (no 7 I think from what I can see online) to check for any cracks/damage to the fuse itself

 

I couldnt visually check the fuse link itself as there was a strip of green plastic covering the links. Does this unclip? I didnt want to damage it unneccesarily

 

One thing I think I should mention is that on Monday I had a pinhole fuel leak to a hose to the fuel rail. 

This was fixed but I did have some diesel spilt around the battery/airbox area. 

I lightly rinsed the area with a water sprayer & sprayed wd40 on the electrical connections just in case they were damp (I didnt spray water the top of the battery or the main engine connector into the rhs of the engine). I thought Id mention this as I think the connection into the steering pump is under the battery area??

 After replacing the hose I remember I had to crank the car for a while to get fuel through (forgot I shouldve primed it first by flicking the ignition key a few times) so the battery may be getting low & be due for a charge - could this have caused it I wonder?

Anything else I could check?

 

Thanks

Scanned the car using VCDS & got the following code:

1 Fault Found:
00566 - Steering Assistance Operation 
            27-10 - Implausible Signal - Intermittent
Ross tech site says that some of the possible causes are 
  • Fuse(s) faulty
  • Battery Voltage too Low
  • Pump Unit faulty
Ive replaced the battery with a freshly charged Varta 096  72ah battery from my last Golf so hopefully the supply side is in order (Fabia one was 61 ah & for all I know was original & nearly 7 years old)
After replacing the fuel hose as stated above & re-starting the car on Monday it took a good few turns to start the car & I could sense the battery was struggling a bit before it eventually started, so perhaps the voltage was a bit low? Only done short journeys since too & its got a bit colder so Im thinking/hoping a fresh larger battery will help somewhat?
 
 
 
 
These are some of the values I got (car was idling & steering not turned). Can anything be deduced from them? Apologies if not as Im a new VCDS user

Did you get it open. At first i removed any silicone that loose and after that I just gave the round metallic case at the bottom a gentle punck with a rubber hammer/club.

FromTheDarkness did you check the fault codes? I got the code: "01309 - Power Steering Control Module (J500): No Communication". This code can not be erased.

I have looked at the cabling on the left side in the engine bay (under the ECU) and  can't find any errors on the cabling. Is the power steering waste or is there anything else that can be checked?

That's helpful info for me, hopefully also for dm222. I got a spare pump recently and want to open it up non-destructively so I can learn about what's inside without wasting it as a spare. Thanks. :)

I need to buy a Electric Power Steering Pump For my 2001 Skoda Fabia Classic SDI 1.9 Any idea the best place to get a good second one from ? I have spent more than the car is worth so far to get this far ?  When I turn the steering wheel left or right I get a wering noise

having had the pump on the on the diagnostic machine it shows intermittent power to the pump

Kind regards

Tommy

Have no problem with loss of power steering but can anyone tell me if I have a 'stop' missing as no problem turning right but on left full lock its as though its going too far and it grates and seems as though its locking the wheel. Ease off a little and no problem.
