Posted the below in VX section, but it seems quiet in there. Someone did mention rusting suspension bits though eek Wondered if anyone here had any ideas? Thanks:

Hello all. Wondered if anyone knew of any problems with my model Astra and suspension/engine bay banging noises.

I had the flywheel replaced under VX warranty a few months ago. Since then there has been an intermittent knocking/donking/banging noise from the front of the car when driving. It seemed to start over on the left of the car but more recently seems to be around the centre of the front of the car/engine bay.

I took it back to the VX dealer who did the warranty work. They checked it and said they couldn't find a fault (the car didn't make a single noise when on the test drive, typical!). So their advice was leave it until it's doing it all of the time then it can be diagnosed and repaired. From what I said they think it may be the Anti Roll bar bushes or something?

It's an annoyingly loud noise when it happens, and it seems to appear when i'm changing gear or slowing down and turning left, sometimes on uneven surfaces, sometimes on flat ones. It makes a banging/pinging noise and I hope it isn't too serious. I'm wondering if everything on the front of the car was disturbed when they did the flywheel change, or maybe something hasn't been put back correctly. It doesn't happen if you go over something like a speed bump though and I can't feel any vibration on the steering.

As mentioned above, it seems intermittent but is very noticeable. Anyone have any ideas? I was thinking of taking it to a different VX dealer and getting their opinion on it, but thought I would check here first.

Thanks all.
