S Type 2.7D display 'reduced performance'
Discussion
Any help appreciated. Booked at main dealer on Wednesday for diagnostics, just wondering what to expect.
Amber warning light + display reading 'reduced performance'
From a standing start to just over 2k rev's, very reduced performance, and noticible smoke out of the exhaust.
Keep the rev's over 2k, and you wouldn't notice that there was a a problem, and no noticible smoke out of exhaust.
Dealer says that this warning doesn't 'normally' result in large repair bills, and £60 diagnostics bill will be knocked off any repair bill.
Any idea's to what the problem might be

Sounds like it could be a Particulate Filter regeneration issue. Very common.Amber warning light + display reading 'reduced performance'

"reduced performance" Means its in limp home mode, Engine ECU reduces power to avoid any posible damage.
Can happen for a number of reasons, sometimes a sensor fault confusing the engine ECU, sometime for faults with the electronic actuators on the turbos.
Only a full diag will tell.

Acording to the user manual, this is 'reduced performance' mode, and is indicated with an amber light.
'Limp home' mode is indicated with a red light.
When I had a 3.0 TiD Saab 95, 'limp home' meant just that, you 'limped home'. If you keep the revs over 2 k with this mode, you don't notice any difference.

Don't think so, it's an 05 with turned down exhaust pipes. I think that means it's is pre particulate filter?
It might be my imagination, but I think when I get the smoke out of the exhaust, it is only out of the left side. Is it 2 seperate exhausts, or one made to look like 2?
No DPF on your car, 2 separate exhausts though.It might be my imagination, but I think when I get the smoke out of the exhaust, it is only out of the left side. Is it 2 seperate exhausts, or one made to look like 2?
Sounds like an issue with one of the turbos
Either the variable geometry turbo blades or the actuator that controls them, sticking

Are you absolutely sure it is a failed turbo?. Early cars had turbo issues but please be absolutely sure that is what it is. I`ve had three in the shop lately with the same faults you describe. Diagnostics did lead us to maf sensor, it actually was deeper and took an age to find. It had been to a dealer previously. He suggested turbo, that it would not be cost effective repair and tried to sell the client another car,than take time in finding the fault.
There are issues with EGR valves on both banks that have both electric motor operation and exhaust gas coolers.If the cooler does its` job the carbon buildup around the EGR valve would not be a problem ,everything/ motor and all would work fine. We find the motors operating the EGR valves are sub standard quality .So the EGR valve sticks with the slightest carbon build up. If water leaks occur and the cooler overheats, the same problem occurs with the EGR valve .The up/ down stream sensors recognise lean running, the diagnostics will lead you to a one faulty MAF sensor, but the EGR is bleeding air ocassinally or all the time. The ecu picks up the problem via the Oxy sensors, then richens ONE BANK ONLY depending on which valve is sticking.Then you have restricted performance and clouds of black smoke from the defective EGR bank.Commion sense really.
Drop in if you wish and let us have a look. Otherwise it will be an expensive non repair.

Shame you are not a little closer.
main dealer assures me that it is a failed turbo.
It was bought from them 18 months ago with a 3 year AA waranty and the AA have agreed to cover cost of new turbo, so if there is any mis diagnosis, I will have to argue the case with the main dealer then.
I had noticed the occassional lack of power over the last month or so when innitially starting up the car and setting off, but as it quickly cleared, so I put it down to my imagination. Perhaps this was the start of the turbo failing?
Thanks for your input, I will give you feedback should the newturbo not resolve the problem.

No Man, they ARE the symtoms of a failing EGR.
So far away?, I have clients from Sweden, Germany and Switzerland bringing their cars here. It really depends if you want the problem rectified or not,
Turbo eh? ,I`m not saying it is or isn`t , but that`s a 6/8 hour job on one bank Locally they charge between £92 and £120 per hour. No doubt they will cream a turbo or two off the AA warranty aswell.So you believe them? eh?, so will the AA because they are dealers after all .With respect,I don`t really see the purpose of the posting if you intended to take it back to the dealer. Seems a total wast of time asking for advice if you don`t really want to act on it.
You don`t seem concerned about the costs or the outcome, as you say" it is down to the dealer" Actually , you the owner, will pay more in premiums if the system is abused ,so get real.Think about it. Nothing for Nothing??? I don`t think so
No wonder the factory are on deaths door.
I found out today that the new XJ expected to be launched at Christmas 09, then march and it has been withdrawn yet again, the launch put forward to May/june.
Apparently some Numpty plugged his ipod into the system and it blew some management system or another.Such is life

RW774, sorry you sound so p*****.
At the time of the post I was expecting a large bill so hence the reason I asked the question, yes, if they hadn't paid up so quickly and without argument, I may have looked further had they chosen the most expensive part as the reason causing the fault.
I have no reason to think the dealer is spinning a yarn, they have only treated me with honesty (just regular servicing (3 in 18 months) with no 'made up' repair requirements) since purchasing the car.
I have been contacted by the AA for details of the fault, so I guess like me, they also believe the dealer or they wouldn't be paying up.
The reason I bought a waranty with the car was for times such as these, sorry if by me claiming for a 'genuine' failure upsets you, and that I came across as not caring about the bill. It is not my responsibility to get the bill reduced and search for other lower cost possible causes for the reported fault, that discusson now the AA have taken responcibility for the repair is there job. As above, had they not agreed to pay up then yes, I would have sort a second nspection / oppinion.
Such us life!!

Not wanting to tred on anyones toes, BUT.
If it was EGR you would surly see the smoke, if its the variable vains stuck on the turbo, it wouldnt.
Also dealer could road test with Diag computer logging boost pressure to check if the turbo or its actualtor was actually stuck to confirm there beleif in the failed turbo.
As I said before there are a number of reasons for the car to go into 'Restricted Performance' mode.

Had this a few times on my 2007 model. First one was when hoofing it up the A1 playing witht Range Rover Sport (childish I know) and turned out to be "air flow imbalance". Just turned it off and on again, and the fault cleared.
2nd time it woudnl't clear soa trip to the stealers was in order and they replaced a sensor.

I know this is old but I have same problem on my 2004 S type 2.7D which has now just done 100K miles
I had the same problem at 60K miles and had the turbo's changed
At that time (60K) nothing would clear the problem and the car was constantly in restricted performance mode and would not rev above 2700 rpm
Now I get the same message but if I stop the car and put it in Park I can rev it over 2700 rpm and if I switch off the engine and restart the fault is immediately cleared
Any ideas on what the problem may be
