Accord Tourer Diesel, 2004 If I work the engine, overtaking up a hill or pushing on in the outside lane of the motorway, the car may suddenly go into limp mode. My local Honda dealer at first thought it might be a fuel filter problem (wrong way round?), but ran a diagnosis that revealed low inlet manifold pressure. They suggested it was a cracked turbo and recommended a new one for £2,500. My usual garage did a smoke test and found no evidence of any leakage. On Honda's recommendation he replaced the actuator for the butterfly valve, £160 no improvement. Has anyone come across this before, and/or got any ideas please?
