Year of Manufacture *: 2003

Hi

Car keeps setting P0400 we have fitted new e.g.r valve and an air mass meter [bosch] Autodata has no imformation on this vehicle. Have checked with dealer to see if there is an update and they say no, would any one have pin voltages and % so we could try and trace any wiring problems car goes into limp mode when code sets.

Any help most welcome

Thanks Terry

Terry if this is an 8hy then its a 1.4 hdi 16valve

Check check and double check the egr vac pipes and the solonoid valve

Hi Steve,
I'm glad I'm not the only one that thought the vehicle was a 14 HDI.
Is a smoke test aligned with an actuator test (to monitor the pressure drop) relevant in this equation.
