156 V6 - lamp unit or rev counter?
My 156 has developed a fault on the rear nearside/passenger side light cluster.
I've read a few posts here about issues with the faulty bulb detection circuit in the rev counter - so can anyone please advise which end of the car to look at first?
1) Indicators on: Brake light flashes dimly. Indicator does not flash. All other indicators work fine.
2) Indicators on, apply brake: Indicator and brake lamp flash alternately, and dimly. Offside and hi-level brake lights work fine.
3) When driving the car, the bulb faulty indicator on the rev counter lights up under braking. I haven't checked this under conditions 1) and 2) above...
What's your advice? Light unit, or rev counter at fault??
