High emissions ? Surely the light would have been on from the time of fill up ? and is this why the light is still On ? When I filled her up time before yesterday with my choice fuel ( Shell V-Power 98 ) nothing like this happened. What to do next ? Should I go for an Italian tune up ?

Should I go for an Italian tune up ?

IMO I wouldn't bother.

with 100 cell cats the light can go on and off at will

You do know what an Italian tune up is, right ?

I'm not sure the MOT guy is going to buy this at emissions check time

It's what comes out the back end that matters for the MOT - not some random light triggered by an over-sensitive car. I'm pretty sure 100 cell equipped cars pass MOTs ok... Stop worrying...

In the handbook it says "Exhaust emission values have deteriorated. Please arrange for the problem to be examined by BMW Service." Could this be yet another Lambda Probe ? The car already had one of these under warranty @ 39 000 in 2006. Is this a common fault ?

Get the fault code read, it may be fook all, but it may have nothing to do with your lamda and be something more sinister. Also be careful which dealer you go to as they may charge you due to the exhaust mod, my ex dealer prob would try

Is it running 100% right?

My normal m3 engine light came on with 100 cell cats but the csl has been ok up to now. Although I have only ever put v power in, but I doubt the tesco stuff will be the cause.

Yeah... the car seem just fine. Still goes like the clappers. Same soundtrack but I've noticed the driver side pair of tail pipes are considerably more foul/sooty then the passenger pair. I wonder if this is an indicator of anything to do with my engine light on ? which it still is.

Just a quick update with regards to my engine (emissions) light coming on over the weekend, after Tesco 99 fill up. The ECU has been interrogated and the only fault (if you can call it that) was the great discovery that I had non standard cats . Both Andy @ Murketts BMW as well as my reputable Indy I've used for many years,collectively pointed at the poor quality of fuel used. Despite the Tesco 99 octane fuel being high octane it isn't always consistent. Remember Tesco being on the News some time ago with people in regular, non high performance cars conking out with failed Cats / Lambda sensors. The fault has been cleared, I added 30 litres of my choice fuel (Shell V-Power 9 to the CSL and all seems well again, after a further spirited 60 miles the light is still out . Never again, Tesco can keep their over hyped, irregular Peesh THANX again to all who cared to share their thoughts
