Hi guys and gals

I noticed today that my 2010 xfr doesn't seem to have an engine temp dial or display. Am I going mad? I only bought it last week but only just realised I can't see anything to tell me when the engine is warm.

 

Correct - it doesn't.

Jaguar have a long history of fitting totally useless temperature gauges and have given them up entirely in the current generation models.

Coolant Level and Engine Temperature are constantly monitored. If the level falls then the LOW COOLANT LEVEL warning appears in the message centre. If the temperature is excessive then ENGINE OVERHEATING warning appears in the message centre:

You need to be especially persistent to find this in the 2010MY Owner's Handbook! See the section highlighted with a red box.

Thanks Graham.

I think some bedtime reading is in order. I also need to see why the blind spot mirror light us not on. Pretty sure the salesman said it had one but I forgot to ask when I picked the car up 😁

 

I don't have this on my Jaguar, but on my Mazda I use this:

ELM327 - Wikipedia, the free encyclopedia

I hook this to my OBDII port and use an app called DashCommand:

DashCommand - Palmer Performance Engineering, Inc.

I Simply mounted an Ipad mini for a display (you could use an old iphone if you wanted smaller for the Jag) and it works great and gives you almost any information you would ever want.

 

Is there a way to monitor the temperature? or at least check it through the onboard computer?

I only ask because I want to see if the engine is warmed up before I begin to drive aggressively. I usually wait 10-15 minutes because I start driving aggressively but I am never sure if it is long enough. On my 335, it would sometimes take 20 minutes before the turbos were warmed up enough.

 

With synthetic oil you needn't worry about engine oil temperature.

The cooling system on these cars is designed to warm up very quickly.

Five minutes driving is enough even in winter. I drive my V6 SC as hard as I like after five minutes of driving.

My engine has stop start which is disabled by the ECU until engine coolant temperature reaches "normal". In above freezing temperatures this occurs within 5 minutes of starting the engine.

Turbos are a bit different to superchargers and the main thing about turbos is oil pressure, not temperature, when you are starting off. Taking care of turbos means not shutting the engine down immediately after a hard boosted run. Even then 30 seconds is enough to allow the hot oil in the turbo bearings to be cooled down with cooler flow.

Superchargers don't heat the engine oil as they have their own dedicated oil supply.

 

Harters - I'm pretty sure the blind spot monitor was standard on the 2010 XFR. When stationary and below a few mph you should see an orange dot in the side mirrors telling you the system isn't operating. Once you are moving along above a few mph the dot disappears and the system is running. Then when a vehicle (or other obstacle) is in the blind spot, an orange car picture should appear.

If you look closely at the mirror when you're parked, you should be able to see the outline of the little car symbol that lights up when in use - if you can't see that etched into the mirror glass then either your car doesn't have the system (which seems unlikely) or someone replaced the mirror glass with the wrong one!

 

It also doesn't work if you overtake a car as it expects that since you passed it you should know it's there.

 

I drove in the Jaguar "R" Academy when I got my car. It was really hot out and we overheated a few cars on the track after exceptionally heavy driving. All things considered they held up amazingly well for road cars being driven like track cars.

When the car overheats, it implements a series of procedures that will protect it. If I remember correctly this included shutting off the A/C and then dropping power until you're basically limping. Smart cars, these!

 

How funny - I've been driving it for a couple of years and never noticed that. But of course it makes complete sense!
