It's a bigger problem where I live in Europe because of the number of diesels. Petrol cars aren't that bad especially when only idling for the airco. Diesels are disgusting idling.
Where I live the density of cars on the highway is much greater than the density of the cars in the field.
For other people (like yourself) it isn't a problem.
I'll stay watching movies at home.
Petrol cars do not do complete combustion and emit carbon monoxide which is toxic. Diesels don't. Modern diesels, running on mandated low sulfur fuel, can have lower levels of troublesome emissions than petrol cars. Trucks are a different matter though as they generally are not subject to the same emission standards at present.
All lies it turns out.
You can smell it easily whilst idling on a warm day with low wind.. and it smells really bad.
I now have the fix and it complies with emissions regulations, and gets the same mileage as before. It was stupid of management and engineers to try to defeat emissions tests because clearly they were capable of delivering the car they promised using the engineering skills they had. Being dumb cost them billions of dollars and has nearly destroyed the company, a fine company. Someone just didn't want to do things right at the time and maybe got off on scamming. Current status is that this car has unbelievably low emissions and gets astonishing mileage and also has high performance.
Only problem is service costs a lot and requires specialized technicians. I hear Teslas and Apple products have a similar issue.
> I can smell it
Mine has no smell before or after the fix. I can smell petrol exhaust.
