We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Clint Sharp
saying something like:

Speaking as someone who used to control field engineers and having had
to arrange for their diesel tanks to be emptied and refilled with diesel
on more than one occasion (all within 15,000 miles of new) after the
muppets filled them with unleaded and drove off, we never had a single
incident that cost us more than two tanks of fuel and the garage costs
for pumping out and disposal of the fuel (how much does it cost to put
the fuel in a breakdown truck?). We ran the cars for over 100,000 miles
and never replaced a pump, in fact we never replaced anything in the
fuel system apart from the filters. 13 Peugeot 406HDIs, one Renault
Espace 2.2DT and an Audi A6 1.9Tdi.

Is the right answer for pre common-rail systems.

If the main dealer is going to latch on to this latest money-spinning
wheeze and charge an arm and leg, you may as well do it yourself. After
all, if flushing out the fuel system fixes it and you get another 40 or
50 thousand miles before the pump expires, you're to the good. If it
doesn't, then your'e no worse off than paying the dealers' prices
anyway.

I've heard of several who've done just what you did and had no further
problems.

As far as CR systems go - I'd suck it and see. Pretty much the same
applies as above. IMO, there is more of a risk, but it can often be got
away with. Much of the FUD about this is put around by the makers and
the dealers as just the latest money-making wheeze, designed to part
hapless punters from their cash.
