Serious blow
We have a 53 plate 307 2.0HDI and recently every journey was enhanced by the ‘anti-pollution fault’ appearing - and an accompanying rev cut to 2,200rpm. This was tolerable because we found that switching the engine off for about half an hour and it seemed to reset and off we go with full power, etc. Having mentioned it on the last service, my local Peugeot dealer gave it a damned good ignoring. Yesterday the car let go in a rather spectacular fashion, with the engine self revving to 5k without the keys in - or indeed me and the wife - and generating enough white smoke from the exhaust to fill three lanes of A road - it now only just turns over. The inlet system is heavily oil impregnated. Any ideas?

‘Anti-pollution fault’ usually means that the diesel particulate filter is
clogged. Sometimes running it on the motorway at 2,000 - 3,000rpm for half an hour or so gets it hot enough to self clean. If it is too clogged this won't happen. If the engine ran of its own accord this suggests that the active mode (where fuel is injected into the DPF and ignited to 'self clean' it) has failed, that the sump has filled with fuel oil and that the level has risen high enough for the engine to run on its sump oil, possibly self-destructing in the process.

Makes sense of the 307. Up to seven forward-facing seats. Good to drive. Decent diesels.
