Today I got serviced my Linea 1.4 Emotion Pk.It was its 3rd service.Everything went out smoothly until I was about to take my Linea back.As I was leaving I noticed that ABS light on instrument panel was on. Few hours before I test drove the vehicle and it was all fine.After the test drive the vehicle was sent for washing and after that only I noticed the ABS light switched on.I immediately informed the SA and thereafter the ECU examiner was attached. Unfortunately the ECU examiner was faulty and hence the problem could not be diagnosed.I took my car back and on the way CHECK ENGINE light also started blinking(not continuously ON) but it got switched OFF after some time.I felt that the car has lost some pick up and engine knocking has increased(ie at low speeds at higher gears). A message saying "ABS is Unavailable" is also appearing on the small LCD.According to me after washing only the ABS light got switched ON. What could be the problem experts ?Is it advisable to drive the car in this condition ? I am planning to go to another dealer after couple of days.
