I have May delivery 230i Coupe UK spec. One of the first with a GPF I guess.

I have an intermittent petrol type smell inside car when it is up to temperature and stopped or just moving off after start/stop. Sometimes bad enough to have to open a window. It clears with driving a normal speed but can reoccur.

I have taken it back to the main dealer twice. They did not find a fuel leak the first time but this time they THINK it is coming from the sport auto breather and want to drop the gear box and run a plastic tube from the breather to the back of the car.

I don’t particularly want this unless I am convinced it is the problem. They said they had to do it on a 3 series a few weeks ago.

My worry is why is there a problem with the breather car on my auto box and not with everyone elses? They say it is there but not everyone notices, but in my opinion everyone would notice this. I have had this box on my previous 220i and various loan cars without problem.

I wonder if it is more likely to be linked to the GPF which may not perhaps have well engineered as a retro solution to the emission standards.

Has anyone else had similar problems or thoughts on the offered solution or likely causes?

I had to look up GPF, it stands for gasoline particulate filter.

Probably not a lot of cars have GPF yet and from what I can tell the GPF is a Europen requirement so we may not have these in the states.

I would take the offered solution vs no solution. I wish car manufacturers did more real world test with a wide variety of testers. But it seems the consumer is the beta tester lately.

Thanks for your advice.

GPF's are part of the exhaust system. They filter particulates out of the exhaust gases. The only reason the G for gas in the name is there is to differentiate them from DPF's where D stands for diesel. The types of particulates is different for diesel versus gas so the design is different. There is no raw gas entering the GPF so I think fingering the GPF is chasing a red herring.

Transmission fluid once used is stinky and doesn't smell like gas even when warm.

In your shoes I would treat the car like it has a gas leak and that would flavor my discussion with the dealer and usage of the vehicle.

Thanks for your guidance which ties in with my layman’s thoughts,

Just curious - had you ever or do you usually fill your gas tank above the first click when it initially shuts off, by manually clicking the nozzle a few more times to get maximum fluid into the tank ?

No I have never brimmed it that I recall. Usually about three quarters full.
