At low speed around town and Idling there is a gurgling sound, I have been told it only happens with the 1.7 Ecoflex and it is how the engine is built?
The Astra 1.7 Ecoflex had the the same problem and Vauxhall found a cure for that car.
Can you please help me to find the solution to be able fix this problem.

The problem is related to the fuel filter. After so long, the filter allows air to get to the low side of the fuel pump. The pump is designed to bleed off the air and hence the sound begins. All research I have done recommends the replacement of the fuel filter.

Thank for your advise. I have just had a full service done at 50,000 and the fuel filter was change but the gurgling noise is still there. Is there a make of a filter you can recommend to stop this or any other option to solve this problem?

The noise is the hard part becasue we can't hear it over internet. That's why we had the video upload installed so you can take a quick video and upload it here at the site. Please let me know, Ken
