Hi.

I have a year 2000 Vito 110Cdi with 116,000 miles.

The other day whilst driving normally at 30 mph my van gave a little "cough" and the EDC warning light illuminated, but no other symptoms. In due course I realised that I was in "limp home mode" with only 3000rpm maximum revs and no turbo function.

A Bosch injection garage diagnosed the fault (£47.00) as a faulty fuel
rail sensor which I promptly replaced (£123.14), only to find
absolutely no difference at all.
On returning to the garage the mechanic again checked the system (and again tried to reset it) but still came up with the same fault, this time suggesting that the fuel regulator, main brain, or even just a break in a wire could be the
problem (even though his £8500 diagnostic kit still pointed to the fuel rail
sensor), and was unable to say how much it would cost.

The van seems to drive OK, considering it's in limp mode.

Has anybody had this or similar problems?

Many thanks
