Hi All,

Help welcomed as I keep having the Restricted Performance message appear. It usually happens when the engine is warmed up and I stop for a few minutes / engine off, then when I start up the message appears. After it comes on, if I then stop/ restart , the message goes away for a good while. It seems intermittent but does not happen then the engine is cold.

The predominant codes related to water in the fuel filter, water in the fuel sensor circuit and EGR temp sensor A - circuit high.

The water in fuel filter seems to have been resolved by a new fuel filter housing.

It is booked into a specialist next week, but thought to check here anyways.

seem to remember another member getting that message. Faulty sensor I think. Do a search  2007 Vogue TDV8 in Zermatt Silver with Charcoal

The faulty EGR sensor fault doesn't cause restricted performance on mine. I replaced the sensor because I spotted the fault code but the fault code soon returned so I ignore it.

Would be looking for a boost leak somewhere. Possibly a split in one of the 4 shoe hoses to the plastic plenum or in the plastic intake plenum itself. There is nothing that can't be fixed with a hammer😜😜

The first code is for a sensor in the NS exhaust manifold, this tells the ECU its running lean or rich this then increases or decreases the fuel trim... If it fails in one position then it will over fuel the car and it makes the exhaust STINK like a 1970s ice cream van!
This will fill the DPF prematurely and cause restricted performance issues too...

As stated above too, there is also a fair chance you have a split intake pipe... One of 4 linking the plastic inlet to the rocker covers

Thank you, so it seems the EGR code would not cause the restricted performance. LR say it is bear being a ghost code. Would it be the water code setting it off then?

Good luck with it sir.......

Thank you Craig

JAS York looked at it and fixed it for me today. It needed a new fuel filter housing and sensor, and a new exhaust gas temperature sensor.

Do you mind if I ask how much it cost for the repairs. I also have the same faults. Water in fuel circuit comes up every so often throwing the restricted performance warning (although it doesn't seem like performance is restricted). The EGR sensor is persistent though and i cant clear that with my IDTTool as it comes straight back on. 2011 RR Autobiography 4.4 TDV8

I have sent you a pm dirtymonkey

Otley Dominic,
Did you get the EGR sensor changed, and if so has it permanently cleared the fault code?

Received. Thanks for the info. Although not local, they are not a million miles away 2011 RR Autobiography 4.4 TDV8

It takes me 1.5 hour drive to get there. But they have a loan car and a coffee shop nearby I worked from for the day while they had mine.

Mike, can you post one of yours beautiful PDF's showing where the sensor is, I'll like to go at it.

Nino,
