Octavia 1.8T, short shift into 2nd gear, low rpm. cold engine, accelarate, can hear a noise like a VW beetle exhaust. I do not drive the car like this as the engine is bordering on labouring, but I have never heard it before, and I have had the car for 4yrs. Recent changes include chip and all belts changed.

Could be a slipping Aux. belt but doesn't sound like it. Any one else heard this.

Regards

Adoks :confused:

Come on guys, someone must have some thoughts on this

can barely remember my car now, been 15 weeks since i drove it :(

If you don't drive the car like that - and you know you shouldn't when the engine is cold - is the noise absent? If so, no problem.

Loose exhaust allowing funny resonance? Which part of the car is the noise coming from?

(Although I share a reluctance to encourage too much testing like this on the poor engine )
