Exhaust Emission Values?

I've just started up the Z4M for the first time in a few weeks (it was fine on last drive) and driving it up the road I notice that an orange indicator light comes on. According to the manual it is the "Exhaust Emission Values" indicator. The Owners Handbook just says to have the car checked as soon as possible. Is it possible it is because of the cold weather or do people think it is likely I have problems? Are there any known causes of this indicator light?
 
Additional : Our last drive was early January
After reading a couple more postings on these forums I remembered I had bought a Creator scanner when I got the car. Plugged it in and read the fault code and it said :
DTC
P0010 a camshaft position actuator circuit / open bank one

I also noticed mention of fuel being iffy and that several ignition cycles might clear it. Well I had already taken it through 2 ignition cycles to go get more fuel anyway. So Started her up on the driveway and ran for a few minutes whilst checking the scanner. Turned her off and started her up again and on 4th ignition the warning light has gone. <shrug>

Shes due an oil service and fluid flush anyway so I'll add that to the list of things to get checked when she goes in.
Does anyone think there is still cause to worry?
 
If the warning light has gone out I wouldn't worry about it, but when it has it's service it might be worth mentioning - assuming you aren't doing it yourself.
 
The gremlins are back. Fired up the car to go for a jaunt today and the Exhaust Emission Values indicator was on again. Drove her to get petrol and started the engine a few times and it seemed to be once the engine had warmed up after the petrol run that the light went out.
Went for a 1 hour trip and when we got in the car for the return journey the warning light was on again. Stopping at a T junction the idle was rough and cut out. When I tried to restart she cut out 2 or 3 times and the EML light came on. Managed to get her going and the EML went out so I kept the revs up a little. It was enough to get home but now the diagnostics have a second error message:

P0016 Crankshaft Position Camshaft Position Correlation Bank 1 Sensor A

So I'm going to have to book her in to RBM asap and hope they can figure it out. :(
 
Well an update with the problems. She went to RBM on 16th April. I asked them to do the oil service, change various fluids (diff, brake, gearbox) and investigate these problems.Dropped it off afternoon of 15th so they could have it all day on 16th. Phoned at the end of the day on 16th and was told everything done. They had a look at the warning codes and also found some vanos codes. Apparently testing showed "vanos intake and exhaust measurement checks are not in spec. The codes also said to check the timing chain if issues persist. They cleared the codes and took it for a test drive and no warnings came back. They suggest if problems persist to seek a vanos rebuild.

I got the train on 17th to go get the car and when I arrived they told me that the horns didnt work, the headlight washer pump was leaking as the pipe wasnt connected and they suspected a slow oil leak and to check the CPV :(

Today I started her up for the first time since the RBM trip and the warning light is back on again. Sad times :(
I plugged in the Creator C501 scanner and the ECM (Engine Control Module) section has a bunch of error codes:
2A81 DME : Inlet vanos, activation 2
2A80 DME : Intake vanos activation
2F80 DME : Engine switch off time, plausability
2A98 DME : Crankshaft - inlet camshaft, correlation
2AA4 DME : Camshaft sensor, inlet, tooth fault
2A93 DME : Intake vanos, activation

I'm a bit knocked for 6 by all this. Do I contact MrVanos straight away for a refurb replacement, that feels like guess work on my part? Would that fix all the error code issues? Or do I need to go to another garage that can tell me exactly what the problem is and what needs fixing?
