Hi to all who have looked, and wondered, at my issue/s. Now that the new member 'syd-c4gp' has reopened this thread from about 9 yrs ago, perhaps it's best to let y'all know the end result. After going to the Lismore dealer back in about March '14 it was taken to a Coffs mechanic who works on Euro cars, and Subarus, for the second time. He had initially scanned and reported the faulty #1 injector which was swapped with #3 to see what happened. At the time of having a 2nd look he was also looking at another RHR engined Peug. He found that #1 injector was still the problem, so we knew it wasn't the injector. After several starts and some thinking he came to the conclusion that the wife's beloved 407 had a compression issue, which he could hear by the way it started.
Drove it home and started looking for info on UK Peug sites and etc. No evidence of comp problems anywhere and no one agreed with the compression diagnosis. The Lismore lads said it goes too well to be a comp issue and I concurred. After giving up on trying to find any enlightening opinions and having no luck in getting Peug Aust interested I took to working on the dark side of the engine to remove the #1 glow plug so a comp test hose could be fitted. Damned if I know how an ex bus mechanic could have such sensitive ears, but he was right as there was evidence of a small leak from 1 of the inlet valves. My theory then and now is that a small part of the thin clip used to hold something to the valve is wedged somewhere and keeping the valve from seating fully.
With a spare car to drive before getting an auto 308 HDi with RHR engine, the old 407 enjoyed the peace and quiet of the Coffs hinterland and still does. With grand kids getting close to driving age it may get a rebirth one day. Que Sera Sera. Thanks for all the help and all the very best to y'all for the soon to be upon us Festive Season ! Cheers
