Default 156 2.4JTD: Turbo Problem?

Hello Gentlemen and Ladies

It's been somtime since I last posted, which I guess tells you that
things have been OK with the lady...that is until the other day.

On three occasions in the past ten days or so, I have experienced a
loss of power under heavy acceleration and a message saying 'Motor
Control Failure'.

This morning I took the car to my local specialist who plugged in the
computer and got the following two messages:

1. P1555 - Accelertor brake feasibility
2. P0235 - Supercharging pressure

Can anyone tell me what these mean? Is it likely to be a problem with
the turbo? Any ohter feedback?

The car is now nearly five years old and covered just over 57k miles.

Thanks

Simon C

If it's a partial misfire or hesitation round about 3000rpm or above,
I'd be willing to bet that the MAF (mass airflow meter) is the cause.
It's not uncommon. A (recon!) replacement from a main dealer is about
140UKP fitted. It's also a straightforward job so well within the
capabilities of DIY or independent garage.

Also, when mine was done, the main dealer found it easier to fault
find the MAF by swapping with a known good one rather than
interpreting the fault codes!

I would seriously doubt the turbo was faulty unless you have regularly
not been letting it cool down before switch off.
