    OK so it needs a session on the fault code reader to find out what the problem is but I just wonder what the culprit could be, my car is a diesel and it occasionally goes to limp home accompanied by the heater coil warning light when under full load, restarts ok with no warning light and runs normally until I need full power which could be the same day or a few days later, just depends on my driving style as I can drive all day and no limp home event.

    the usuall culprit is a clogged vnt mechanism within the turbo. either remove and strip the turbo in order to clean it or fit a new one. there are products you spray into the turbo to remove the built up carbon but these are usually only a temporary solution. a good italian test drive can also help, gets them hot and moving. being a taxi i would imagine you drive for economy..

    Which engine type code, BKP?
    Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.

    Engine code is CBD if I have deciphered it correctly, yeah, I suppose lack of regular high speed thrashing won't help as I am on autopilot around town mostly returning an average of 40mpg. It's going for a session on the code reader later in the week when he gets his laptop back.

    Engine will be a CBDA, CBDB or CBDC common rail as all 'C' engine codes are 4 letters. I'm guessing yours is MY2009 / 2010??

    I believe these have a DPF which is not good for town driving either. Needs a good run once a week with a decent amount of right foot!

    I would expect a fault code read to show an underboost problem and this is nearly always due to a failed turbo actuator. There is a repair kit for this from VW (most TPS depots keep three on the shelf) and these costs £146.18. If you do get this code, remove the rubber pipe to the actuator from its connection at the valve and suck on it, you should not be able to draw air through. The catch is that to fit it is very fiddly and it must be set up on the computer display so its output voltages can be observed. We have had to set quite a few up for other garages.

    It was plugged in this morning and yes indeed it was the turbo boost actuator, seemingly there is a diaphragm inside which goes goes but I will be entrusting the work to someone else as I have lost interest in diy repairs since engines were fitted east and west. Long live the Rover v8 engines.

    I'll second that. I can dismantle my MG into its component parts with a set of AF spanners and a couple of other tools I've got in my garage.

    Then again, I suppose it only needs a small plastic card to do the same with a Passat.
