I bought a seven year old Xsara Picasso from a Citroen dealer 16 months ago. The car has one year’s warranty and 60,000 miles on the clock. After six months the injectors had to be replaced (covered by warranty). Now the seals have gone again and need to be replaced. Could there be any permanent engine damage? If this has happened twice is it more likely to continue?

Have since read your recommendation to leave engine running for a minute before switching off but as I have to move between jobs every hour this could be difficult. Is it better to cut possible losses and change? If so what economical car would you recommend to fit 3 children plus car seats in the rear? I average 20,000 miles/year (motorway and around town).
