Can I convert my 2019 Skoda Superb L&K petrol automatic to a diesel engine?
No, we would not recommend converting your 2019 Skoda Superb L&K petrol automatic to a diesel engine. Modern cars are highly integrated systems, and an engine swap from petrol to diesel is far more complex than it might appear. It is not simply a case of replacing the engine; you would also need to change the transmission, ECU, wiring harness, fuel system, exhaust system, cooling system and potentially even suspension components. The cost of such a conversion would be extremely high, and there is no guarantee that the car would function as intended afterwards.
More importantly, such a modification would not be legal under current Indian regulations. The RC of the car specifies the fuel type, and changing it from petrol to diesel is not permitted. The car would not pass RTO inspection, and you would not be able to legally register or insure it.
If you are looking for a diesel car, the best option is to sell your current Superb and purchase a diesel vehicle. This will be far more cost-effective, reliable and legal than attempting a conversion.
