2007 T31 X Trail 2ltr Diesel
The engine management light has come with fault code P0235 i.e Turbocharger boost sensor A circuit malfunction ... I have a cheap diagonistic tool which reads the fault code and resets it . It will come on again usually after the engine has been stopped then started several times ... There is usually no change in engine power but sometimes acceleration is poor ... like the turbo is not kicking in on these occasions ... Had it with the Nissan dealer and they reset the light but it came on again after a few drives .... Has anyone any experience of this or know what the problem is

Nissan dealer reset the engine management alarm and advised that if it came on again replace the sensor .... total costs ÂŁ250.00 .... The dealer Hursts have been very good and not charged for the reset and i love driving the x trail but have been through the DPF problem and fuel filter issue and the maintance costs have been considerable this last year..

The sensor was changed at my local Nissan dealers ( Hursts Boucher Road ) last week and this has fixed the problem .... Costs for sensor and labour approx ÂŁ70.00 .... heavy snow last week and I am well pleased with how the X-Trail handles in these conditions
