I drove home tonight in my 57 plate 2.7 diesel s type. Headlights went out then straight back on again. Did it 3 times in 3 mins. Any ideas anybody?  

I do know that the contacts in the steering column light switch are notoriously fragile so that might be a place to start.

Thanks for reply Raistlin. Will give it a try in the morning. Bit scary driving in country at night and the lights go out. Will be doing a 100 mile run tomorrow. So hopefully will be able to fix. Cheers. 

Agree with Raistlin. My X350 drove me nuts switching lights off and on at random and I think it's the same switch. Lots of info on forums about it but probably under X350 , check under flickering headlights. Might be worth checking earths as well. My problem was a frayed wire inside the direction indicator / light switch.

Good luck.

Hi guys,,im having the same problem,,the lights keep flickering on and off after a minute or two,,driving me nuts too

Any help would be appreciated,,before i get the hammer

 

Mine used to flash at inappropriate times such as when someone passed me or someone in front was waiting at traffic lights  so it was quite important to get it fixed. I took a chance on a used switch off Ebay which had other faults but I managed to make one out of two and it's been fine ever since . Very easy to fit on the X350 and I'm sure it's the same switch on the S Type. If I remember correctly either 3 or 4 screws keep the bottom half of the cowl behind the steering wheel on, then three more accessed from underneath keep the top half on. The switch assembly is held in place by a couple of clips so you press the clips in and pull the switch off. When you look at the new one all will be revealed .

 Quite an easy fix with a soldering iron and shrink wrap if you fancy having a go.

Good luck

I knew I had some photos somewhere. Sorry they're a bit mixed up but hopefully you can make sense of them. There's a write up on Jaguar Forums in the X350 forum under Flickering lights when turned off.

Thanks PD for the info and pics. Will try and get a new switch.
