159 mystery noises!
Am a tad paranoid after reading about gearbox issues on the 159 1.9 JTDM. The car has made a background noise since I've owned it (about a year / 10,000 miles). I thought it was coming from deep inside the dashboard.
It kind of sounds like a faint whirring - a bit like a lathe sound. It doesn't really increase with speed and doesn't stop when dipping the clutch or going into neutral. It has recently had a gearbox oil change and nothing has changed there. It's a background noise, not really offensive but I want to be cautious.
It starts at approx 30mph but doesn't make a noise on idle or when revving the engine. The noise doesn't get any worse as the car warms up and it stops as you come to a standstill.
Also, it now makes a more audible chirruping sound at lower speeds. This is quite audible with the window down - sounds like it is nearside. Bit of an odd noise and hard to describe but also a bit of a worry.
The gear change seems normal and the clutch is fine as is the running of the engine. Wonder if anyone else has experienced similar or if there is anything obvious to check. For example, could it be a wheel bearing.
I am concerned it could be transmission although, as I say, it's been like this for approx 1 year and 10,000 miles.
Any ideas / thoughts appreciated!
