Hyundai i30 model 1600 cc Auto. diesel, now done 60,000 miles. About 10 months ago, I had difficulty starting the engine from cold.
The temperature would have been in the 50 to 60 degree Fahrenheit range.The glow plug lights came on several seconds before starting.
The car dealers said that the glow plugs required replacing, and this was done within the 5 year warranty, i.e. no charge.It seemed to cure the problem
Ten months later I am having a similar problem, the engine never starts first time. The outdoor temperature range would be about 40 to 50 degrees Fahrenheit.
Yesterday, it wouldn't start first time, the second time, I kept the starter on continuously for about 10 seconds, the engine turned over slowly and gradually gained momentum, and eventually started.
Once the engine is started, it starts up, first time during the rest of the day.
Does the car need new glow plugs again?
First of all thank you all for your comments, I have found them interesting to say the least. I tested the car's battery the other day, whilst the engine was not running, the voltage being 12.89 I have booked the car into the dealership in 3 weeks time. It will be left their overnight so they can check the engine form cold. I am not very confident that they will trace the fault.
I have forgotten to mention that about 6 months ago my son was driving the car home from his work, when suddenly the car's engine stopped, he managed to pull over to the side of the road. He then started the engine up, and it started. We have had no further incidents regarding this. Again I took it in to the car's Dealership, again they were unable to trace the fault.
I will take a copy of the answers you have given, and show them to the service manager. and see what he has to say. Thanks again.
