Engine Cutting Out

[Tony Saunders]

Hi Everyone. I have a problem with my 2013 plate XF 3.0l V6 Supercharged. I have had it for around 2 years without problems. One day I was driving a few miles from home and the engine cut out which also meant the power steering cut out too. Fortunately I was on a minor road and pulled over safely. I put it into my local garage and they replaced the fuel pump and 'module' which is what their diagnostic tool told them was the issue. Got it back, same thing happened. They now have the car back, but are struggling to identify the issue. Any thoughts or experiences???

Hi Tony......welcome to the Club

That is worrying if it cuts whilst driving.
Has the car had enough prolonged usage to charge the battery?
If not, this can lead to similar issues as can leaving the car sat for many days/weeks at a time.

Has the fuel filter been replaced recently?

Hi Trevor. Thanks for your reply. The car is driven every few days or so and the battery appeared fine i.e. it starts first time. I checked with the garage that they had checked fuel filters and they confirmed they had. I was lucky I was on a minor road. If I had been on the motorway and it had cut out and the power steering had gone it could have been very serious.

Hi Tony

I presume the garage is not a jag specialist. I suggest you ask them for the fault codes they pulled from the car then post them here so we have a better idea of what the problem is. I would also get the battery checked properly. If you have the Stop/Start system you should have an AGM as the main battery which has a different voltage profile to a wet cell battery (12v at rest is virtually flat!). If you are only using it every few days for local journeys the battery will not be having a chance to re-charge. As with many modern cars these are essentially a load of computers each talking to the others over a network and they hate low voltages, responding with all sorts of weird errors. In the first lockdown I left mine too long and completely flattened the battery meaning the rear doors were permenantly locked and the windows did not work. All that was needed was a reboot using the garage computer 🙂

Thanks for your email John. I have sent your suggestions to my garage (not a Jag specialist) to see what they think. As it happens, the stop/start has also not been working, so you may be on the right lines. I didn't think they could possibly be connected!!!  Regards Tony

Hi,

Found this from an Australian site. Does your VIN fit in the number range?

Recall J067

Jaguar XF 2012MY and 2013MY
Selected vehicles within the VIN range SAJAC0627CNS53474 to SAJAA0227DNS67338

Jaguar XJ 2012MY and 2013MY
Selected vehicles within the VIN range SAJAC1627CNV38178 to SAJAC122XDNV43625

What are the defects?

The engine may not start, or may cut out without warning. If the engine cuts out, the vehicle will lose brake power assistance and Power Assisted Steering (PAS) will also be lost, with the vehicle requiring increased steering effort. If the vehicle is fitted with air suspension system, the system may reduce the vehicle to its lowest ride height position.

....Forgot to say this is due to faulty Crank Position Sensor.
