This problem has the merc garage beat.
Clyd Head has been removed for heater plug removal and injector combustion leak,pressure tested fine,cleaned of all blow back of injector rubbish in manifold and rebuilt perfect.Runs like new up to a point.
A new underbonnet wire loom has also been fitted by merc along with the rail pressure valve. The vehicle will not run at more than 3000 rpm (safe Mode)the computer says error on connection fault.It's been checked million times to no avail,now they are saying we just have to live with it, it can't be cured. Does anyone know if this stupid safe mode can be removed from the cpu control unit,or has it ever been done???

We have now had the problem sorted....it was a leaking vac hose.But we did find a company that can recondition the cpu units in essex,£450 or they will do a test for £120.
