hello

this sounds like you've run over a plastic carrier bag which has melted onto the exhaust and sump

sorry to say there's little that can be done other than to keep on driving it to melt it all off

probably best to go for a long motorway drive where you can get it hot with enough windspeed to keep fumes from entering the car
