Hi, i have a 2008 l200 DI-D 4life which has just developed an intriguing fault- in first gear the engine revs to 3000 revs and gets up to about 12 mph and then will not go further,if I change into second gear everything appears to be as it should. Any ideas please?

did it not do this before

no, this is new

when was the fuel filter last changed ?

last winter, but the vehicle is only used in the summer, and has had about only 6 fill-ups in that time.

There will be a switch on the clutch, check to see it is attached, adjusted correctly or electronically sound.
It sounds to me like its rev limiting because the ECU is seeing a depressed clutch when it isn't.

Did you ever find the problem, as I've got the exact same in my 09 l200 , won't rev past 3000 in first gear but when out of gear etc it revs fine, no warning lights etc?? Thanks
