This site is a small gathering of people experiencing distribution problems on THP 1.6 engines. (EP6 PRINCE 1.6)
A shift in the distribution appear gradually and results in destruction of the engine.
At best your engine will go into degraded mode and operate with reduced power, the worse it will break.

This is a transcript of a Radio France emission: In France we are starting to get the problem recognised; we are fighting to be heard.
A Jean Remy MACCHIA Chronicle:
Gasoline engine Peugeot-CitroŽn / Mini 1.6l question regarding reliablilty:
This is not an epidenic, nor a sacrifice (not sure of that bit) as with the 1.5l DCI engine from Renault installed on the Scenic and Grand Scenic 2003-2004. None the less there is some repetitivity to the technical fault which affects the functioning of this 1.6l engine.
An engine you will find on some CitroŽn C3, C4, C5, DS 3, DS 4, and also on some Peugeot 207, 308, 3008, 508, 5008, and on all of the Minis.
What's happening to this engine?
A concern over the timing chain. The metal timing chain is an engineering choice made in place of a rubber timing belt, to eliminate the risk of breakage, and is expected to last the life of the car without any signifigant maintenance.
On this modern engine released in 2006, there is in fact a concern over the hydraulic timing chain tensioner.
First you hear a metalic sound. More often in cold weather. At the start the noise goes away as the engine warms up.
At this point one should already be alerting the brand representative (a Mini SA for us)
Otherwise the concerns become worse...?
Exactly. If you don't visit the representative, the noises amplify, with clacking that doesn't go away once the engine has warmed up.
Now you have an engine where the timing chain is not held in place properly. This allows the valves to open out of synch...
In the end you have an engine that doesn't work correctly, with losses in power, and it can go worse.
First, you can have a badly worn timing chain (''stretched'' more precisely?), which will require replacement, but that's not the worst that can happen.
There is a risk of engine failure, a low risk, but it did happen to Frťdťric. To his 207.
How are the manufacturers involved responding?
Meaning CitroŽn, Peugeot and BMW - on their Mini model. First they minimise the extent of the problem. Even if the engine failures aren't frequent, they do happen none the less to some cars, and particularly to those that have a turbo. For example on some CitroŽn or Peugeot ę THP Ľ and the Mini Cooper S.
At the factory, the tensioner in question was modified in 2010.
After sale, the attitudes differ amongst the 3 manufacturers.
Replacement of the tensioner costs between 180-200 Ä.
Replacing the chain costs between 700 and 950 Ä, and all these "cures" are only partially covered by the manufacturers. This despite insistant calls to After Sales Services (Warranty department?).
And the responsibility taken, if there is an engine to change, is only partial.
