I am the recent owner of a Citroen C5 VTR PLUS NAV HDI (2010) 1.6 diesel estate, manual, 046000 miles. I have a few questions for C5 owners, having spoken to Citroen garages a few ‘warnings’ have been mentioned during conversation, and some problems I already have, and as this is my first C5 I’d like to get a feel of what I am in for: Has anyone found heavy tyre wear on the inside if the tread at low milage, power steering seals failing at low mileage, sat nav screen switching off mid route, crank shaft oil seals leaking oil over the aux belts, and I have been advised to change the engine oil & filter every 6 months, regardless to mileage as the engine could seize. Any thoughts ..
