Hi Anand, One cause for ECU failure is due to excessively high stray high voltage levels within the engine compartment or by unusual signals being seen by the ECU`s sensor inputs. If this situation occurs, then it is strongly recommended to replace the high voltage system with new genuine parts (i.e spark plug leads, distributor cap, rotor, coil) and the main engine to body and battery grounds are renewed before fitting a replacement engine management ECU. [Editor] Electrical welding on the body or exhaust can cause these stray currents and result in an ECU failure. Disconnect engine and SRS computers before doing any electrical welding on the car. Tell shop personnel (especially muffler shops) to do the same if they work on your car. Darwin.

Thanks Darwin. My car had done only 10,000 Kms in 2 years and was under agency maintenance.Recently i had some starting trouble and when checked by the service ppl, i was told that the ECU needs to be replaced. Initailly they told it will cost 8000INR and later they came with an invoice of 15,000INR. Is that this much expensive??Do you think the price is the original price of the genuine product? Can you tell me why this is damaged at this stage?

Hi Anand, ECU stands for Engine Control Unit. It's also sometimes called the engine management system and is a small electronic box that monitors and optimizes the operation and performance of your engine. Before ECUs were fitted to cars, a carburettor controlled the quantity of fuel entering the cylinders. The level had to be set manually, and often required adjustment at service intervals. Replacement ECUs can be expensive, so it's worth thinking about the potential price of a replacement if you're considering buying a used Galaxy. Thanks Darwin.

    Hi, Tata Indigo XL returns around 12 kmpl mileage with petrol and around 21kmpl with diesel, which is decent. The 1.4-litre petrol engine has been tuned for more power than the fuel efficiency, which is the reason behind its low mileage figures.
