The design of the filter housing fitted to HDi's was changed significantly during 2001, whether this later type is any better at its job I've no idea.

Having said that, there was a former Peugeot trained mechanic,now running his own independent Peugeot specialists, on one of the forums who claimed that the problem of this swarf getting past the filter was down to poor practice when changing the filter element more than anything. He said that swarf in the filter was very common on HDi's, and as long the filter housing is cleaned very thoroughly when changing the element (or just change the complete housing) then it doesn't necessarily cause any further problems. Apparently he looks after several high mileage HDi taxis that had this swarf in the filter problem early on, and are still running quite happily at 200k+ with original high pressure pump, injectors etc.

Slyman,
I would have firstly put a new fuel filter on the car and then filled it up with diesel. Having had petrol put into my car in the past (mine is diesel), I just drained it like you have and filled it up and kept it topped up for a week. This with thin down the effect of the petrol. The car may run a bit hotter but only for a short while. In fact you may even get a slightl better mpg out of it!!

Am I not right in thinking that petrol is lighter than diesel and will float on the diesel?? If this is the case most of it could be removed via the big aperture under the rear seat and then keep the diesel topped up.

My personal take on it is this.

If there is swarf in the filter then there's something fundamentally wrong with the design of the fuel system. So that says it all.

Is it worth taking risks, a complete new dealer fitted injector pump, injectors, etc. is going to cost well over a grand maybe 2! A new VW filter will cost about £10 from GSF + a few bits and pieces for fitting it.

Anyone who runs Petrol through a common rail system has more money than sense. These systems are using parts made to tolerances that are usually seen in the aerospace industry. There's a massive amount of difference between the old TDs and the HDi. For example it's a usual practice to crack the injector pipes to check for fuel flow on TDs, whereas with HDi's you are warned that such practice is dangerous due to the presures involved.

Steve.
