Smoke, misfire, flat 1.9PD

[pigfarmer99]

Hi,

The current Mrs Pigfarmers 05 plate 1.9 PD has in the last couple of weeks developed a bit of a problem.

Bimbling along it's fine, push the throttle and it hesitates, misfires and chucks out a dose of smoke (black through to grey) and gets going, but it does feel slightly underpowered (mind you I'm used to my vRS).

We've changed the fuel filter and put a shot of injector cleaner through, but no improvement.

Fuel economy is still the same, no sucking noises, local garage VAGCOM showed NO recorded faults. MAF, turbo & DMF were replaced a couple of years ago.

Anyone got any ideas ?
