Jaguar F-Pace Non Runner
Discussion
I had some spare time to look at the A/C not working. Previously I'd found a menu on my diagnostics I'd not seen before which was a compressor run-in procedure which is supposed to be done after you change the gas. I'd done the procedure a few months back but it still didn't work. The code I'm getting is P1308-13 which is for the compressor clutch. It's a permanent fault (if the A/C is on). There are 3 fault codes for the compressor clutch short to power, short to ground and mine which is open circuit high resistance.
I had a look at the wiring. The one I was interested in is the third one from the bottom on the climate control module. Violet-white - AC clutch relay control.
I probed it with my tester while actuating the compressor via my diagnostics. There was nothing happening. If I gave it 12v I could hear the clutch on the compressor work. I ran the engine and gave this wire 12v with my tester. The A/C worked fine. I'm ruling out the clutch/compressor (it is the 3rd one fitted at this point).
The strange thing is why I'm not getting an output from the HVAC module on this wire. I bought a replacement in case this had a fault. It made no difference.
After doing the run-in procedure the first time the system now says it's been run in on the diagnostics. It didn't previously.
When I look at the freeze frame data for the fault code it says the compressor run-in is incomplete.
The P1308-13 fault comes up during the run-in procedure. Part of the procedure is to clear the errors but maybe my diagnostics isn't capable of doing what it thinks it is doing. Maybe I need to take it to a dealer or someone with dealer level diagnostics at this point.
As I writing this post out I thought of some other stuff to look at. I decided to check the resistance across the clutch of both the old compressors and the one on the car. Both compressors were showing 0.02 ohm. On the car measuring from the HVAC ecu pin it was 0.03ohm. I pulled the fuse for the HVAC module and checked it, then traced the power back just to confirm it was defiantly the right fuse (logo looks like a heated window). Then when I did a compressor clutch test on the diagnostics and it clicked! The fault code was gone, I started the engine on and the A/C now works.
Not got a clue what has sorted it out. I can't see how it's just a bad connection on the plugs as they've been removed and re-fitted plenty of times. I even took the cover off before to verify the pin on the circuit board had continuity to the other side of the plug.
Thought I'd post this as there is nothing on the internet for this fault code, it might help someone in the future, although my answer was mess about until it works.

Similar question - a friend is thinking of selling her immaculate (not even a single stone chip on it) 2016 16 plate Disco Sport HSE Luxury.
I quite fancy buying a car from such a good source, and had assumed it was a petrol car as there was no mention of TD4 on the back.
I went on Autotrader to see what sort of price she would want, and what the economy, road tax etc were like, and was surprised to find that not only were all 170 of them on AT diesels, no petrol cars, but it was most likely a 2.0 too.
I guess the advice re barge poles is similar?

Really, it seems to be a combination of correct type of use and overservicing that seems to prevent failureI quite fancy buying a car from such a good source, and had assumed it was a petrol car as there was no mention of TD4 on the back.

Petrol version only went on sale in 2017, AFAIK. Apart from the pre-Ingenium 2.2D's, I think they're all 2.0?https://www.autoexpress.co.uk/land-rover/discovery...
Unless you do regular motorway or dual-carriageway driving, I'd avoid. Hacking out the DPF solves one issue but makes the car illegal and largely unsellable.
It’s funny, and I don’t knoe if this thread has contributed to it, but when the F-Pace came out I wasn’t impressed.
Didn’t like the way it looked & was very much against a Jaguar SUV.
However as time has passed these look better & better.
I saw a lovely dark grey V6 S the other day and thought it looked great.
Maybe it’s just the classic Jag thing that the older tgey get the better they look.

I suspect she does mostly local miles.
I will ask questions and ask to see the service history if I want to take it further.
I suspect that she may not be aware of the Ingenium issue, but I think that she does less than 10,000 miles a year, as she lives locally and is often at the stables during the day time, so the car may have had time-based rather than mileage-based services.
If I buy it , I will be wanting it for caravan towing and continental touring, so will definitely be doing longer distance trips.
