Yes thanks apart from the bill lol drained tank full flush and new fuel filter engine seems much smoother now which is weird.

Yes and also the cost of a tank of "wasted" fuel.

Would have decarboned it a bit?

Way, way back (pre-tdi days) we used to throw a liter (about 2% of the mix) of petrol in the workshop Toyota Hilux diesel (circa 1979?) because the boss reckoned a little bit of petrol or metho was beneficial for starting. Used to throw plenty of other rubbish in the tank too - it was a very agricultural engine.

I know almost nothing about diesels (still) & this isn't something I'd recomend as it appeared to make no difference.

On damage to you fuel system, it depends. Diesel acts as a lubricant for the high pressure furl pump, and so, while everything may appear OK, damage could well have been done. A friend of mine had a Mazda CX9 Diesel and his daughter did much the same thing as you did. He did not even get off the forecourt because it was running so rough. It ended up costing him over $3,000 in repairs to the engine and fuel system.

The PD engine doesn't have a high pressure fuel pump. You are thinking of the CR engines. The PD engine has a low pressure fuel pump and it has a plunger in each injector for the high pressure.

A PD TDI passat is not a CX-9 (and thank goodness for the OP)

Does that help or hinder in this case?

Helps.... the piston pumps do relatively small movment to generate the high pressure, so it would take a lot of running on petrol to damage the injectors from wear.

Ok thanks...

Fits ok amalgam?

I use one of these and it works as advertise. Even tried to fit an ULP nozzle and it prevented insertion.

Very happy and would recommend it without reservation.
