In fact, there was once Engine Malfunction error displayed and I took the car to service centre very next day. They were unable to identify any error and told me that no error code was stored in the memory and it should have, if there was an error. It left me confused. They also took a "TEST DRIVE" in my absence for 50km and handed over the car back to me saying there is no problem. Apart from this, there was never any error sign displayed ever.
Hope you received my email
