Hi I have my new Astra LS (well a year old). On the test drive before buying I noticed the steering hydraulics were quite audible, it complained on turning the steering wheel, and at rest with the engine idling a hum can be heard in the car. I have driven Astras before and while I have heard them complain on tight turns etc, never heard them at idle above the engine noise before. Anyway the dealer said a mod kit was available as it was a known issue and they would fit it, I have the car now but it hasn't been fitted with the kit although they have agreed to do this and to run the car for a few weeks and come back where they will sort that and anything else out at the same time. They seem very genuine about this so I have no concerns that they might be trying to fob me off. I am just wondering if there are really mod kits for this problem? If not, what they should be doing to correct the problem so I know it will be resolved on the first trip back? Regards Philip
