Why Datsun Go Is Prone to Black Smoke from Exhaust

The Datsun Go uses a 1.2 HR12DE petrol (67 bhp) and is classified as a hatchback. Based on our workshop experience with Datsun Go in Hyderabad: HR12DE timing chain noise at 70,000 km. We also see black smoke from exhaust in vehicles that share similar engine architecture to the Datsun Go.

Top Causes of Black Smoke from Exhaust in Datsun Go

• Clogged air filter causing rich mixture from insufficient air (most common and cheapest fix)
• Faulty or leaking fuel injectors over-delivering fuel
• Faulty MAF sensor causing ECU to over-fuel
• Stuck-open EGR valve allowing excess exhaust gas recirculation
• Turbocharger compressor wheel damage allowing oil into intake

How We Diagnose Black Smoke from Exhaust on Datsun Go

• Air filter condition inspection — replace if grey/black
• OBD2 scan: fuel trim data, MAF sensor voltage, injector duty cycle
• Smoke leak test on turbo intake side to check for oil leak from turbo seal
• Injector back-leak test for diesel engines

Prevention

Replace air filter every 20,000 km — a blocked filter is the cheapest fix for black smoke and often the cause.
