Well, my 2006 cdti (150), 200K on the clock got a strange problem.
The problem would appear mainly when i depress the accelerator and below 2000rpm, never above. Mainly when the car have not reached the running normal temp. and most of the times in urban circuit.
There´s a intermittent power loss, when i accelerate,nothing happens, then i disengage the gear, accelerate in neutral, two ot three times, and the car comes back to normal. If i continue with my foot down the accelerator, the car eventually awakes but only after a couple of seconds(or minutes, should i say) but sometimes not...
Randomly the spanner light comes on the dashboard but just until the malfunction disappears. There are no registered error codes.
Already replaced the throttle body, but seemed not to cure the problem.
Already cheked the vaccum hoses. Have put a fiat gasket on the EGR a year ago with no problems whatsoever.
What might be?
Sorry my english...
