mercedes turbo engine

[raido]

i have a 990m Rapido motorhome on a Mercedes sprinter chasis. When going uphill the motor home slows down to approx 10 miles per hour. does anyone know what the problem could be.
Thanks

Could be any number of reasons, Is there an 'engine check light on' ? which might indicate the engine is in ' Limp Mode', Could be a Turbo link pipe has come off ? Did it go Faster uphill before ? has this happened recently ? Think you need to call at a Merecedes Commercial garage. For them to hook up their Diagnostics.
