I'm thinking about buying new diesel Modus...however I found ...
The following report at HonestJohn web site in connection with Renault diesels..
should open to allow carbon dioxide, (which acts as a cooling gas) into the combustion chambers when the engine is under load (>30% boost). This allows the combustion chamber temperature to drop and thus the temperature of the exhaust gases.
If it sticks in the closed position the exhaust gas temperature will rise causing
bearings to fail and
b) introduce engine
into the induction system.
This can cause the engine to run on its crankcase
until it is either stalled or goes bang.
valves in Renault dCi engines
are also the cause of rough running when the valve is stuck in the open position. In several cases turbos have blown but the
valve has not been replaced. Inevitably the new
unit will not last long.
Any feedback from members?
