I picked up my 35iS 2 days ago and it goes really, really well - but I have one concern in that when I get out or am sitting at traffic lights I sometimes am getting a waft of coolant smell.

This is with the roof down and definitely from my car as it has happened maybe 6 times. It is strong enough that a friend mentioned it.

There is no smell in the car when I first get in it and the floor is not damp, nor the car smelly. I can get the smell through the air vents a bit when the air con is first turned on but not after that via the vents - as it has been on with the weather so hot but the general smell is from outside with the roof down.

I open the bonnet and can't smell or see anything.

Any ideas ? I may ring the dealer (though they are miles away) or take it to a local BMW dealer just to check for peace of mind. There are no puddles of coolant .... just the smell.

Where is the coolant reservoir on the 35iS ??

Any comments appreciated.
 
Take it to the dealer, can only think you have a small less somewhere.

Have you checked the level?
 
Where do I check the level ? I looked under the bonnet but couldn't see the usual reservoir.
 
Level seems ok - the float popped up showing the level (car cold) was right underneath the filler neck.

The cap wasn't tight though - a good half a turn away so I have retightened it. The cap says turn until it clicks yet there is no 'click' it merely goes tight and two arrows one on the reservoir and one on the cap, line up.
 
BMW came out and checked it - 20 minutes after ringing them ! Most impressed. No fault found but expansion tank cap not on tight (about half a turn loose) so he thinks that was the cause :)

I am now going out for a drive :D
