Any ideas ?

as above, if driven around town it will be caked up with gunge due to modern Derv's designed for long Motorway trips, Does the EML come on? I guess the 90's don't have the FAP system

That's what I've done on both my current and previous 306, which shares the same engine as the 406 HDi 90.

Turned out that replacing the injectors with a complete.set of known good ones sorted it. (It ha been fitted with a couple of the original injectors as the replacement engine had a couple of damaged one's)

Somebody who can decipher the live data and what is happening when the error occurs using Diagbox or Peugeot Planet will be able to pin the fault down in a matter of minutes. Don't bother guessing and playing the parts lottery.

Engine starts ok , ticks over ok and does not overheat .
Will try to get it plugged into a diagnostic machine this weekend and have a look down the back of the engine .

Get onto 406 coupe forum, they have a list of member's who have Pug Planet

I am running out of time as I have 3 weeks family holiday in this car coming up so I will take it up to Peugeot tomorrow and have them put it on their diagnostics .
New aftermarket MAF sensors are quite cheap on Ebay , I normally wouldn't touch them but might be useful to try a swap with a new one rather than an unknown used item .

Have a good check round for boost leaks too, particularly the hose on the turbo outlet. Best to remove driver side wheel to access that.
I'm not familiar with 406s to be honest, do they have a DPF?

Took it to a local garage to put it on the diagnostic tester , they checked it over and saw the smoke from the engine bay and said there was a crack in the induction setup and it would be best to fix that first . They offered to do a test with the smoke machine to find the leak but that would cost at least £75 so I decided to have a look for it myself .
By revving the engine while laying under the car I found the smoke was coming from the flexi joint in the exhaust system close to the turbo , there was also a 3mm dia hole in the weld at the flexi , put some heat wrap and a Jubilee clip round the hole as a temporary fix .
Will try to get a new MAF this week and try that and then go the diagnostic route next weekend .

If it runs better your maf is screwed

I think others have had trouble with the cheap EBay MAFs. Try and get a good use one or genuine Siemens VDO (ECP on a sale weekend!).
