4: Engine squeak. Has anyone else got this problem? It occurs after about 4-5 mins after start-up and immediately after start up. Give it a bit of throttle in gear then lift off the throttle and there is a noticeable squeak, every second or so for 3 or 4 times then you've got the give it more throttle and it appears again, eventually it disappears but its bloody annoyingf. I've suggested that it might be the rocker pot on the LHS of the Engine, as if you rock the engine, when off, it rings slightly, the other thing I thought it might be, is the flexible joint between the exhaust downpipe from the engine and the main exhaust, as it may be temperature related. Anyone got any thoughts?
I have the EXACT same problem on my Polo 9N.
Same 100 1.4 engine as yours and same annoying squeaky sound. When I give it a bit of gas, let it roll and simply let the engine draw the car with no power, it squeaks. It does this in pretty much all gears and I've narrowed it down to being the gas-exhaust return valve, with the help of my VW garage.
When I disable this by unplugging it (its a small green plug in the front of the engine), the squeaky sound stops. When I plug it back in, the sound returns.
The dealer has acknowledged the problem and replaced the ERG twice, but it STILL squeaks and its driving me mad..
If anyone else has a different way of solving this OR another idea about what it could be please post it.
Apart from that I've had all the faults:
* dashboard rattles
* squeaky front suspension
* engine loosing power (updated the engine ECU)
* Universal joint defective, replaced after 40K Km.
* Steering wheel wobbles
* seat belt suspension squeaks
* sprinklers replaced
* Ignition coil replaced twice
I am never, ever going to buy a Polo (or even a VW) again.
Living in denmark I had to pay 20.000 pounds for this car...
