Hi , newbie to the group and I have a question I hope someone can help with . I have the 3 litre x type 5 speed auto ( 2004 ) and this afternoon I was driving along at 70mph and noticed the rev counter was only showing about 1300rpm , I thought this was a little low or do  you think this is right ?

Hi Tony,

Can't really comment on the X-Type, but my 3 litre XF (6 speed) does about the same at 70.

Cheers,

Jon

Hi Tony, And welcome to the club.

I had a 2005  2.5 litre petrol  x type with a 5 speed manual gearbox that showed a 1500 rpm at 70 mph which is about right for the smaller engine.  I guess that 1300rpm for the 3.0 engine is about right.

Regards,

Peter.

Thanks guys , can I just ask , what do your engines idle at when warm? I only ask as mine sounds fine at idle ,no rough or lumpy idle , but the rev counter only shows about 400 rpm.

Hi Tony, 

Your owners manual should tell you what your tickover revs should be,

My S type has the V6 2.7 litre diesel engine, and my manual ays that it should be 750 rpm at tickover.

And at 70 mph it runs at 2100 rpm.

Regards,

Peter.

Hi again Tony,

I may have mislead you - I just checked - mine does about 1550rpm at indicated 70mph.

Apologies for that.

Also idles at 750rpm (missed that bit!) - distracted by manhole covers in Azerbaijan!

I just spoke to an independent jaguar specialist who told me the revs at idle should be 750 -800 . This confirms that the rev counter isn't working properly . He said that you have to change the instrument cluster as you can not calibrate them . This also involves the use of 2 keys to programme the cluster or the car wont start . Going to have an interesting conversation with the dealer I bought the car from I think !
