hi everyone, can someone please help me. when my 407hdi is cold the car pulls away very slowly,almost on tick over, as soon as the revs pick up its ok, could it be something to do with the cold start?
It might be lack of turbo boost. Check turbo boost sensor and turbo boost control. Also check MAF sensor. Hugh from City of Glasgow

Two things you could check. All your flasher bulbs for clean, sound connections and good earth also - long shot - brake pedal switch connections or the switch itself faulty. Hugh from City of Glasgow

which years were fitted with feul pump+sender and which years are just feul sender thank you.
All 407's have a both a fuel pump and a fuel sender unit, without a fuel pump no fuel will get to the engine. A fuel sender just sends a signal to the fuel gauge to show how much fuel is in the tank, it doesn't send fuel as such. Mick from Portugal
Why not say what year your car is and whether it is petrol or diesel? For example the 2005 407 with 1.6 2 kitre HDi engines with Siemens pump do not have the combined fuel pump and sender unit you are referring to, they do not have a pump in the tank. There is a rubber bulb under the bonnet to prime the system during filter changes etc and for normal operation the suction side of the injection pump acts as a fuel lift pump to feed the high pressure side. .

Hit a bump and has been showing powering steering faulty, ESP faulty, ABS faulty, gearbox faulty, braking system faulty, airbags faulty etc. and does not kick when I try to start vehicle ever since.
You need to scan the OBD2 port to see if the scanner can communicate with the system. Check the fuse box in the engine bay for corroded terminals also check other loom connections for corrosion or poor joints, unplug and replug all visible loom connections . You may have a dry solder joint in one of the car's printed circuit boards, need an electrician to test out. Hugh from City of Glasgow
Thanks, Hugh, it worked. It was a loose terminal on the BSI. Michael Ugochukwu from Nigeria

Hi,I'm currently trying to figure out what is the issue with my car. It's a 3l V6 Tiptronic transmission. If I start the car and drive for an hour or so the oil temp goes up to 80- 90 deg and then when you select drive or reverse the car has a thud or jerk like I'm leaving the clutch to fast but it's automatic so I'm stuck. Had the gearbox drained and original ATF fluid filled from Peugeot, about 7l. I hope someone can help me for I am going grey. Many thanks.

Hello! I recently fitted a gearbox from a 307 to a 407, and the cruise control stopped working, although the speed limiter works but just won't engage, all the other sensors (brake and pedal) work. I took it to Peugeot and they told me that's because of the different gears ratio, and that's why is not working. Just wanted to know if this is true? Cos they want to charge me a fortune for a new gearbox. Thanks for the attention

Hi I have a 2006, 407HDI 136bhp SW model and have been given 7 litres of commercial 'add blue' to top up my de-pollution system. Does anyone know if lorry 'add blue' is ok for this vehicle? Thanks in advance Tony
This might destroy your engine! I have a 2007 2.0hdi 407. Mine does not take Add blue. It takes Pat fluid. Addblue and Patfluid (Eloy oil) are 2 different things. Addblue gets injected into the diesel particulate filter (its 70% water) but Patfluid is injected into the diesel tank Paul Mccartney from Armagh
