Idle

[ub7rm]

mine was a bit lumpy the other day, put some new petrol in and it was fine again

This is another possibility, I wangled a full tank of petrol out of the stealer and somehow I can't see them filling her with the good stuff.  I've topped up with 99ron but maybe when there is pure 99 running through her that will make a difference.  I've mentioned it as part of the other niggles so will see if they come up with anything but if not it sounds like there is nothing to worry about.

I have an 08 model with 3000 miles on the clock and at idle it has a burble that sounds more like a quiet v8 engine than a diesel.

I had a Saxo Diesel before the GTI and in no way does the GTI sound like the Saxo.
