Hi all, My car has suddenly started making a low bassy rumbling noise whenever the air-con/heater fan is on. The volume and pitch increases as the fan power is increased and is always present regardless of any other control, unless I turn the system off completely. It doesn't sound like the rasping noise I'd expect if there was a leaf stuck, this sounds much more like a blowing exhaust. The noise seems to be coming from the passenger footwell. Does anyone have any suggestions as to what might be the cause might be? Thanks, Chris

Thanks for the replies, interesting to hear others have noticed similar behaviour. I thought I'd read of someone else mentioning this in a post when I first joined but I can't for the life of me find the thread! I'll mention it to the garage when it next goes in and see if they find anything. If anyone has any experience of garages acknowledging the issue I'd be interested to hear what the outcome/cause was. If it is a 'feature' then it's a little disappointing as it can be quite noticeable in 1st, 2nd and 3rd. I've ruled out my driving style as I've had the car a while now and I experience the drop and surge in power when I'm deliberately being very conscious of my driving technique. Cheers, Chris

Hi All, I have recently bought a 57 plate 1.8 TSI L&K with around 30k on the clock, and am so far very pleased with it. A big step up from my old diesel Ford Focus which didn't always start! I have one question though, and I'm not sure if this is normal behaviour, the beginnings of a fault, or just my driving style whilst getting used to a petrol car again. I've noticed, and it only seems to be when the engine's cold, when trying to pull away slowly/steadily (ie not flooring it after the traffic light turns green!), that the turbo seems to kick in briefly, then drop out, then kick back in again, over a period of about a couple of seconds, giving the the drive quite a 'lumpy' feel. This is mostly predominant in 2nd gear, but also in 3rd. If I drive it a bit harder I don't notice it. It would be between 15 and 20k rev wise. Once the engine's warmed up I don't notice it but I don't know if this is just because I've got accustomed to the feel of the car over a journey and whether it is just uneven pressure from my right foot on the accelerator, or whether there is a fault developing with the turbo which would cause such behaviour? Or is this just how the turbo on this engine behaves when cold? Any thoughts would be welcome! Cheers, Chris
