Hello, Im anew member. Ive got a 2.2td xtype based in south Africa. I developed an engine warning light and a computer test showed it as a faulty lamda sensor which I see is not expensive and consists of a sensor end and a wire plug. THe problem is that I cant find it and don't know how to change it and neither does the local garage!
2 upstream and 2 downstream. SEARCH the code when you get it in this forum and it will tell you where and how to change it. Make sure you buy an OEM one and not an Asian knock off. They won't work.
What code? It identifies the sensor so without it no-one can tell you.
Thanks for the response. Its in south Africa and Ive been back to the garage and he cant remember the code but looked it up at the time and said it was an o2 sensor. The car runs ok but doesn't like being cold or first gear/low revs when it lack power and has to be revved above2k and makes smoke. Someone said its clearly a fuel air mix problem as power is good on the open road. He looked at the air line from intercooler and via turbo to inlet and all seems ok, no sucking or blowing noises or dodgy hoses.
Im a bit at the mercy of local standards for this car as its pretty rare here. If the lamda sensor is easy to replace I think that's the best pragmatic option
Hello, Im anew member. Ive got a 2.2td xtype based in south Africa. ......
Welcome to the forum Hugh,
I saw London as your location and immediately assumed you are in the UK. However, your IP Address shows Fraserburg in Northern Cape, South Africa. Presumably both you and your vehicle are somewhere in South Africa?
You are going to make little progress with this issue until you get the actual codes. It sounds like the garage may have used a generic lookup for the code(s). If so, this can often be very misleading with Jaguars.
The diesel variants are so often mis diagnosed, and in a lot of cases the injection pump/ and or injectors are blamed.
Whilst a leak off test is very useful, I have seen many people have both pump and injectors replaced with no cure, only to find the inlet metering valve has been faulty all along, that is causing the lack of pressure.
Of course pumps have been known to shave themselves and swarf up the injectors.
One good way to kill it is if any petrol/ gas has accidentally been put in !
Generally speaking the 2.2d injectors are good for 200 k, and 2.0d injectors are good for half that.
My car is a early 2.2d, as the emissions were excellent, I wanted to preserve the engine best possible, so I did a full service with all Full synthetic oils, and filters, and I use top end diesel with millers additive that increases cetane value as well as extra lubrication for the pump,, to best preserve the fuel system.
Besides blanking off the egr, I also used a can of bk244 to clean the carbon from head/ pistons etc.
This gives me a good baseline for the car to work from.
To this day I cannot get it to show any visible smoke even at night with car headlights behind, and it starts perfect any weather without and missing or roughness.
Paul.

Dear Paul, thanks for the short but crucial reply! I went back to the garage who decided to have a closer look rather than plugging it into the computer and lacking the detailed codes.. On the history of the fault they cleaned the air intake sensor and bingo! It drives perfectly though I have to back to get the error signal removed
Good news HWR !
On the diesel a poorly working mass airflow sensor (maf) causes hesitation pulling away at junctions.
Also the maf is used to sense correct operation of egr flow too.
