All my local jag specialists are busy til mid April, so took it to Auto repairs MOT in Maryport who took the time to read the codes with an autel scanner and wouldn't take money for it despite my best efforts. Codes read after clearing. P0635-11 Intermittent - Power steering P0635-13 History -Power steering B100B-67 History - Column lock ground authorization B112B-87 History - Steering wheel module B1B101-67 Temporary - Key transponder - We think this was from me walking off with the key in my pocket while it was being scanned B1B101-87 Temporary - Key transponder B1B33-64 History Target identification transfer, signal plausibility failure U0121-00 History Lost comms with ABS My focus is now on B1B33-64, which the autel scanner said can be caused by immobiliser problems etc but also... *drum roll* By pressing the engine start button for a few seconds after the drivers door is opened, and every time I open my car the infotainment says alarm triggered by: drivers door Parked the car up at home because of course it worked totally fine at the garage. Stopped and started it a few times no problem... but as soon as I opened the drivers door it refused to start again even after I closed it. Could all this be caused by a dodgy drivers door sensor? Oh and as for the battery I am missing one socket from my set, the exact one to unscrew the holddown to get the thing out.

Have only had the car less than a year so all I can say is that the battery is "older than that" Got the battery tested at the local garage, they said it was absolutely fine, but I'll put it on charge anyway. They cleared codes and we will see what comes back. Is it safe to disconnect the battery as I live in a flat so can't charge it in car.

Battery tester arrived. Battery seems OK? Also did a scan with my questionable SDD clone. went nuts when I scanned it with half the systems faulting on the dash so half of the errors are probably false. Starter relay and steering module are both okay once I get the cluster lit up it starts fine.

I've ordered a battery/alternator/ripple tester that will be here tomorrow, my multimeter seems to have grown legs sadly. Im still thinking the washer has either leaked into wiring or a corroded connector is intermittently pulling the voltage down.

In regards to start/stop it's just got the usual push to start, no aux battery. It does have 2 washer pumps. Haven't gotten battery tested yet as it refused to start for 10 minutes today at the shops so had to rush to work instead. Cold started fine at 2c within half a second. The push start light wasn't lit, and the info display on the cluster wasn't powered up. The infotainment system just was grey with small jaguar logo on. Tried the backup key slot and that did grab hold of the key but didn't do anything, either pressing brake and pushing start didn't do anything either. Not even a weak start attempt. After a long time screaming obscenities the cluster display came on and car started nearly instantly. Good strong start so I doubt it's battery. I've noticed dome light has randomly been on or off when I start car, and beeps on lock/unlock have been random too. First time it's totally refused to start today. From a little googling I notice a lot of these symptoms could be a bad bcm between that and the washer not working I'm wondering if the bcm is located in the driver's footwell where a washer fault may cause liquid ingress? There's been no wetness in the footwell but I have noticed a bit of condensation when I've started the engine, but have just put that down to the cold.

Sorry to bump this, but I'm having almost identical symptoms with my 2009 3.0d xf s. Engine systems fault popping up anywhere between 5 times a second to every hour. Engine start/stop sometimes not working, double beep on unlocking drivers door (computer says triggered by drivers door) and screen wash motor not sending water to the screen, but is to the headlights. When the engine sysyens fault is popping up a few times a second my indicators work slowly almost if they are... Lagging. No obd2 codes stored.
