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. -- Z Scotland Alfa Romeo 156 2.4JTD Veloce Leather 'Oil' be seeing you..
