Hi

I have had the fault codes of my 406 2.0 HDi yr2002 read.

It has come up with fault code 1166 on a Siemans ECU. Does anyone know what
this code represents? I am having very poor fuel comsumption (33-36mpg at
absolute best) so hopefully it is going to be something to do with that.

On another note I need a new seatbelt pre-tensioner for the driver's side -
is this likely to be expensive and/or is it easy to replace??

Thanks in advance,
Ol

The car has now been to a main dealers for the fault codes doing. The
report is as follows:-

ECU Fault Code: P1166
Engine Speed: 864RPM
Measured injected flow: 8.96 mg/impulse
Coolant Temperature: 47 deg c.
vehicle speed: 0 k.p.h
Battery Voltage: 14.35 Volt(s)
Engine Status: idling
Time elapsed since ignition positive: 42 second(s)
Diesel Temperature: 38 deg. c.
Diesel pressure: 410 bar(s)
Pressure regulator OCR: 0 %
Flow regulator OCR: 22 %

"Intermittent fault. Diesel high pressure monitoring. Pressure controller
at stop."

Peugeot tell me that my economy problem is due to the DIESEL PRESSURE.
Apparently 410 bar(s) is far too high. They have suggested i examine the
high pressure pump, and sensors.

Anyone any other ideas as the high pressure pump does not sound easy to get
to.

TIA
