Citroen C5 X7 Tourer - engine died

[Huntmaster650]

My wife's 2.0 HDi Tourer (2009) cut out the other day. After trying to start it unsuccessfully, I locked and unlocked the fob and it started, then drove 20 miles with no further issues. Checked the OBD2 codes, came up with P1166 - fuel pressure. The car also showed Faulty Engine Management System on the dash. Cleared everything, but the next day it died again. I turned up 15 minutes later, locked and unlocked, started first time but cut in and out a couple of times on the way home. Code P 1166 again and also the code for the crankshaft sensor. Today, I changed the sensor and fitted a new diesel filter. So far, fingers crossed, running perfectly and much smoother at tickover.

Thank you for sharing your experience. All these is worth its weight in gold ( I mean FIXED ones); I wish everyone would share the malfunctions they experience and their successful repairs.

If it's an RHF engine like I suspect then it's probably the fuel pressure regulator on the way out. It's a known issue. My old 2L used to stutter, never had a stall though. Replacing the FPR cleared it up.
