T4 Petrol/Temperature Gauge intermittent failure



New Member
Hi. It is becoming quite common for my Petrol/Temperature Gauge to fail in my Petrol T4. Either they are both working, or neither is working. (They are both in the same display face) Often it seems as if they don't work for a while when I start out, and then I notice that they are back in business.
Can anyone suggest where I might find the problem?
