They did say to me that maybe this problem only occurs once the car warms up a bit, after driving an hour or so... kind of makes sense i guess if the oil changes viscosity after being driven for a while. They say if i go down there when its making the noise they will get a mechanic to come out with me if there is one free and let them hear the noise! seems good fo them to suggest such a thing. i must say they were quite helpful down there im rather impressed.
the lady who was dealign with me also said that the polos may have a problem with the syncro mesh in the bo? i dont even know what that is lol. she said they are considering that ads a possible problem with the gearboxes that maybe causing them to crunch like they do.
still i do have a year of warranty left so maybe i should just try and break it then take it in and say " SEE NOW THE BROKEN GEARBOX DUM,B FUCKS HMMM?" lol.
id like to re-iterate that they were actually helpful and overall i am happy with the feedback i got bar the lack of a fixed GB.
