Ds3 Power steering Fault help please!

Post by sixfoottwo »

Hi all,

I am hoping someone can advise please.

I have a 2013 Ds3 that has been sat for a while, battery is fine checked that as are the fuses but when I start the car which is no problem power steering Fault flashes up on the screen.

I have a coolant leak if that has anything to do with it (I doubt it) due to damaged coolant bottle to rad pipe which I have ordered - getting that tomorrow.

Any help much appreciated, not risking driving it at the moment.

Thank you

I would first consider giving the car a run if it has been sat for a while. A lot of these glitches can iron themselves out once they have had a run and had a chance to operate properly over a few runs.

Failing that, if the faults are still there, then what actual tests have you done on the battery to say it's in good health? Starting ability isn't an indication of battery health though, and as the power steering is electrically operated directly from the battery, this may be an indication that the battery is not in the best of health.

You may benefit from giving the battery a good overnight charge, but make sure you follow the BSI Reset / Battery Disconnect / Reconnect Procedure to avoid electrical problems.

Failing all of the above, and if you are then still getting a message, you will need to have a diagnostic run on it and then post up the fault code along with the VIN.

Hi Marc,

Many thanks for the reply.

Ive charged the battery and then tested it with a multimeter and it comes back fine, I also did the Bsi reset but still the same.

The only thing I haven't done is give it a run due to the coolant to rad pipe leaking which I'll do tomorrow all being well.

I have scanned it with a Bluetooth obd app called car scanner off the app store but that shows no faults which is odd!

Generic scanners are usually only for standard generic codes and most likely cannot read the manufacturer-specific codes that only a professional level diagnostic tool can read. So your scanner may not be able to pick up the fault if it is not a standard code and as this is specific to the Power Steering, that may be why.

The power steering system is very sensitive to having the correct voltage, so that may be a factor.

Argh ok, that will be why the app will not pick it up then going to try FAP after a search as some people it seems have had a bit more luck with that.

Battery does seem ok, car starts 1st time/windows operate fine/radio/lights etc fine and I even like I mentioned had it on charge for a few hours until the charger said battery full. Multimeter reads 13.51.

I don't really want to buy a new battery as I'm sure its ok - it is 9 years old though!

That's about double the generally accepted service life! As the battery ages, its ability to hold a charge diminishes, so although it may be fine for starting, the capacity becomes less and less, so it can affect electrical systems in the car that need a constant voltage. Just for you to be aware, but see how you go with the other diagnostic software App.

Yep, realise the battery is quite old just trying to avoid buying especially as that may not be the issue!

I'll give it a scan and a run and see if anything changes, will report back.

Well that didn't go well.

I bought a NavWay Bluetooth obd coonector and it fails to connect to fap.

As promised I'm back! And it's a strange one!!

I haven't cleared the codes and the steering Fault has disappeared off the dash! Steering is as light as a feather!!

I've got Fap connected finally using a a vgate Pro obd and it has come back with the following fault.

I also scanned it with another app and this came up

Any ideas??

VF7**************[VIN obfuscated, can be read by forum staff].

Ive just took it for a 10min run and white smoke was pouring out the back so turned engine off and checked the engine and it was hot and the coolant had dropped to below minimum and it turned a different colour!

I checked the oil and that has no milky colour on it so hoping its not the head gasket!

I should now rename this to White smoke and coolant loss with no signs of a leak!!

I'm not getting P1234 as a valid fault code for this vehicle, but here is the other one:
Fault Code: P3008
Description of Fault: Air circuit : Air flow higher than recommended. Ratio of measured airflow over calculated theoretical airflow below 10 % detected for 2,5 seconds.

The following conditions have to be met to trigger this fault code:
  • - In the pedal release phase
  • Air temperature between -20°C and 100°C
  • Battery voltage between 10 and 16 V
  • Turbo pressure between 740 and 1500 mbars
  • Engine coolant temperature between 50 and 110 degrees C
  • Engine speed between 1400 and 3000 rpm
  • Engine speed variation less than 16000 rpm per second
  • Air mixer open
  • Exhaust gas recycling valve closed
Conditions for Fault to clear: Driving for 5 minutes with decelerations of more than 10 seconds.
Downgrade Modes whilst Fault is active:
  • Switching of the turbocharging pressure regulation to controlled mode.
  • Deactivation of the request for regeneration of the particle filter from the diagnostic tool.
Symptoms:
  • Jerking/stalling
  • Noise
  • Lack of power
  • Smoke from the exhaust
  • Slightly higher fuel consumption
Suspect Areas:
  • Atmospheric pressure sensor in the engine management
  • ECU
  • Air flow meter
  • Air leak between turbocharger and mixer
  • Leak between air mixer and engine inlet (including EGR take-off)
  • Leak on the air mixer
  • Leak on the turbocharging air cooler
  • Turbocharger
  • Turbocharger fixed geometry control electrovalve
  • Turbocharger fixed geometry position repeat sensor
  • Turbocharging air pressure sensor
  • EGR exchanger with bypass
  • EGR exchanger bypass control solenoid valve
  • Position switch for the EGR exchanger by-pass
  • Electrical harnesses
  • Connectors

Cheers Marc, really odd on the power steering just fixing itself! Anyway I see smoke mentioned in the above as a symptom.

Coupled with the loss of coolant and it turning a different colour plus the fact when I opened the bonnet it was actually red hot in there around the turbo area so maybe its that as that's mentiond in the suspect areas.

I'd certainly keep an eye on that and any smoke as that tells me 'leak' of some kind....
