The V8 Owners Forum -

update:

I have unplugged and plugged back various connections, took it for a 60 mile round trip this morning, and the issue was gone. Hopefully it was just a dodgy connection somewhere and reseating several plugs etc has fixed it.....

I don't think it's the level switch. When driving on a road with no bumps, holes etc. it's perfectly fine.

Thanks for that Chris.
I'll have a look in the morning.

Do you happen to know if the car actually switches back to petrol when the lights go out, or it's just the lights being funny?

Hi everyone :) New to this forum and hoping to get some much appreciated help. I have a Lexus Ls400 with a BRC system. Recently the fuel level indicator lights have been going out every time I hit a bump or pothole. Then slowly come back on 1 by 1 and it switches over to LPG again until the next bum...
