IR is severely effected by sunlight, tungsten or even fluorescent light (well the ballasts of the driver not the actual light spectrum) and indeed is often referred to 'interference'.
Gilly - my IR range isn't 'affected' by sunlight it's eliminated!
I have two questions for MB.
1. Can I buy the sensor assy. without the barrel and if not, why not, as these are clearly separate assemblies?
2. Why did MB change to a single IR receiver in '98 - seems very suspicious to me! Coming from the design world there two over whelming reasons for design change; design/manufacture error and cost.
I doubt it was for cost reasons (due to limited number of cars sold and total car value) and so I have my suspicions of design error. And it took around 10 years to discover and implement the change - perhaps I'm just a sceptic!?
More testing tomorrow
