I haven't had the codes read yet. Taking Disco 2003 in to trusted maintenance guy on Monday but always value your input. Have had two leaks for a while, power steering fluid and antifreeze. Keep refilling as needed. Last week new noise started, that increased in intensity as I pressed on gas pedal, then seemed to disappear after driving for 10 minutes or so. It was bitterly cold here so I thought it was related to that, but it continued as weather warmed. At times the Engine light would start to blink, so I checked fluid levels and added to fill. One of my friends listened to the sound, he is a mechanic, but couldn't figure it out and said the belt looked like new. He said there was a lot of leaked fluid everywhere. Any ideas would be helpful. thanks
