Shame.
................I know a bloke who tried top get some technical info from a Ford forum last week. It was going to cost him £20 to get an answer from an "expert". 
Mrs TB's dad paid £12 (I think) on an Audi forum for an expert (daft fool should have called me first).
Symptoms were no power and high fuel consumption on a 1.9TDi Audi A4, circa 1996.
After a few days, the 'expert' came back saying blown turbo due to age (its done 270k)

, Useless halfwits

.
I just happened to be over there one day, and he asked how easy it was to change the turbo. I'm not an Audi expert, but even I know those symptoms are due to the vac pipes for the boost sensor and the wastegate valve perishing. All Audi TDis suffer it beyond 100k, 10yrs.
So a quick visual look (didn't have any diags equip with me), sure enough, one of the vac pipes had perished at the end, not sealing. Snip, push back on, test ride, all as good as gold. Told him to replace all those fabric covered pipes (same as the leak off pipes on our Omega TDs).
30s to find such an obvious fault.
Twelve rather quid for a poor, unrealistic, illogical, wrong, expensive diagnosis.
Its certainly a route I don't want to see OOF go down.
