Good morning, I am new on this page, so I present myself. I have an Hyundai Matrix 1.5 CRDI 180,000 kilometers and since June 2012 it began not to start from time to time, you could spend 15 days perfectly and at 16 suddenly it did not start, but in the middle hour it gave it the contact and started normal.
In Gamboa Motor (which is possibly the chorizos in Spain) they told me that I had to rectify 3 injectors and change the diesel pump, because according to them it is where the computer failure gave (this is impossible since the machine only detects sensors does not fail within the pump, or of the injectors). I have cleaned injectors and rectified one that was wrong in Sansan workshops in Madrid (which is possibly the best firefighter and also a very good price) and the car is much better (softer, less consumption, etc ...) although it warned me that this was not the failure so it does not start occasionally, after the month of the month "plas" again fails.
In Almoauto workshops they put the machine again and they have shown me that the failure is in the € 80 € camshaft sensor and in the € 120 crankshaft sensor (Hyundai already uses Hyundai with the prices of spare parts).
After many headaches this has been the solution, changing them after a month no failure.
Therefore, what I recommend to the people who have this failure is that for injection failures and bombing workshops Sansan in San Diego Avda (some monsters), for diagnosis Official Almoauty Workshop on Alcalá Street, very good treatment and professionalism.
Never gamboa that are sausages.
