Any bods on here maybe point me in the right direction with a bit of a problem on my Sprinter.

Occasinally (usually going up a certian slip road onto motorway uphill) The engind decides to not rev past about 3,000 revs or about 45-50 MPH. Almost like it`s in a safety mode.

It`s happened on this same road three times now, and at other places.

It goes on like this until I pull up at work and switch off, then seems ok again.

Anybody have any ideas.

cheers

Tony

 

Something stupid like Low Oil or low Water putting it into Limp?

.

 

either check the switch on the clutch pedal or you havent put you foot slightly ont eh clutch pedal have you?

 

do they have ejr (sp?) valves ? I know they can cause variouss vans to throw a hissy fit ?

 

EGR = Exhaust Gas recirc.

.

 

there is a vaccum sensor under the airbox check that, also check the map sensor

 

This is the way forward.

There is a vacuum solenoid valve under the airbox that controls the turbo boost pressure. They usually go fucked causing loss of power.

Give the clutch switch a visual inspection. Make sure it's not loose.

 

Had a problem like this on a 51 plate at a place I worked at, annoyingly intermittent that usually showed a clear when the mechanic plugs his computer in, It turned out to be a 10 bob sensor on the nearside of the engine, just a fucking nuisance to diagnose.
