We own a 2006 1.8 TDCI and it has 74.000 on the clock. On Wednesday it started making a blowing noise similar to when you turn the heater blower on but its coming from under the bonnet somewhere. It only happens when your driving and happens when you get to about 2ooo RPM, weve tried revving it whilst stationary but the noise doesn't happen. Any ideas anyone?

Thanks Chris.

I don't know if you've got to the bottom of this yet, but it would seem that you have a leak on your turbo boost pipework. The turbo on the 1.8 TDCi seems to come to life quite suddenly at about 2000 rpm, whereas the 1.6 and 2.0 Which are Peugeot/Citroen engines, are more linear. It may just be a hose clip, or a split in one of the pipes, or it may be something more serious like damage to the intercooler. If you haven't already got it sorted, check over all the pipes between the turbo and the engine. If the leak is bad enough, it may even be causing the engine to lose power or smoke under load.

Hi everyone,I thought the engine were made at Bridgend centre of excellence by Ford and also fitted to Peugeot and Citroen,perhaps this could be confirmed,regards ccharlie.
