Why does my diesel car blow black smoke?
Black smoke from a diesel car means too much fuel or too little air. Start with the air filter — a ₹1,500 part. If clean, check for EGR valve soot (₹3,500 cleaning), turbo oil seal failure, or injector back-leak. GarageNation diagnoses diesel black smoke comprehensively before recommending expensive injector work.
