A few months ago the rev counter, fuel gauge and water temp gauge stopped working on my 2000 tt & at the same time the low oil pressure warning light started to flash.

I've had the clocks changed now & the fuel & temp gauge are working fine but the rev counter still doesnt work and the low oil pressure lights still flashing.

The pressure is ok as ive had it checked but someone said the warning light could be flashing as it takes a reading from the rev counter as well as somewhere else.

Any ideas what could be causing it folks?
