Hi, I have a 2006 SW model. The car had 33k on it when we bought it and now has 89k on the clock. It has only cost me a passenger side front ball joint, and €50 to get the tyre pressure monitors disabled by the main dealer as they are troublesome. There is a chirp from the clutch taking off, but this has been there since we got the car and is a common problem. I also replaced the small turbo air inlet hose as it burst, bringing on a warning lamp which was reset when the hose was replaced. The car has never let me down and returns 54mpg. the level of equipment is great and the build quality is also very good.

Good points on Peugeot 407 1.6 HDi:
Very big place inside car,very economical.
I have this car just 2 year but 2 times changed ABS sensor wheel from rear passangers( left and right side) only 45k miles and gear box lines was used :( then after 200 miles again mechanizm at the gear box for change :(
Thats too bad for low milage.At 180km/h something strange voice from front windscreen.

Owned Estate version for 3 yrs, problems in that time.
(i) New clutch at 50k (done under warranty, common fault).
(ii) Both front ball joints replaced (common fault)
(iii) ABS front wheel sensor replaced.
(iv) Suspect AC fault, never gets the temp in the car down to low levels like some of its rivals.

Other than that no problems, motor has now 100k on the clock, runs well, good fuel economy.

Have a 2004 Peugeot 407 1.6 HDi 110 SE 4dr model - cam belt went at 42000 miles - engine totally trashed - very disapoint Peugeot UK do not want to provide any assistance - have only owned the car 2 months!
