hi guys
I just bought a Jaguar XK 4.2 V8 2006 with 110000 km, has always been my dream and I am very happy but I there has been a fault light and let me know if I can help and I bought it on a sale and could not answer me my questions.

Yesterday I appeared yellow engine light made ​​me an elevated temperature in the engine and the very next day the engine light came on yellow FAILURE.
The error I could locate a ODB reader and I got error in lambda probe.
It may be for the type of gasoline I use?

That gasoline used because in Spain there is 95 and 98. I caught him putting 95 as the manual but a friend advised me to have 98 and can use that has fouled the catalyst?

Then one thing I've noticed that the radiator fan works much in the city and do not know if it is normal.

The car runs perfectly and no loss of power.

thank you very much guys

 

I would highy doubt it is the gasoline, but could be a faulty water pump with that kind of mileage. I would't drive the car too much knowing that it is over heating. You don;t want to take the risk of blowing an engine due to exceesive overheating.

I am sure that others will post a response, and most likely with a diffferent diagnosis. Stay tuned for more.

 

The message of high temperature does not appear.
He stayed fault light stayed to delete and re-ignited just days.
I think this car has 4 lambda probes and the 2 occasions that went on was a mistake every time. (first one and then the other) so I think it's not the fault of the lambda probe is difficult because they broke down two at a time.
The car has my mechanic's workshop because Jaguar is far from my house.
Thank you again.

 

I'd try to determine the age and condition of both the catalytic converter(s) and the oxygen sensors themselves. Lambda out-of-range codes, but with the car running perfectly, to me suggests that something has worn out in the terminal exhaust components.

Today my mechanic change the spark plugs because they were wrong.
I think that will be enough.
I'll have to change the water pump? who knows ...
I will keep you informed.

thanks for the help.

 

the problem of the lambda probe seem to be solved by changing the spark plugs.

The problem is still overheating problem in the city, on the road does not pass never happens.
When I'm in town and I light traffic message appears high engine temperature.
I just changed the water pump and radiator.
I think exite a thermostat on the water pump, can this be causing this?
Thank you guys.

 

Hi,
Changing the thermostat or checking it for proper opening points is highly recommended. Also know, a proper coolant mix with water is preferred over 100% water. Does your Jag have electric fans? Is so, make sure they are coming on at the required specification (temperature)
Good Luck..Buena Suerte!

 

Thanks for the prompt reply
the fans start very fast.
when I go into town at 5 minutes are activated.
thanks again
