2005 Peugeot 407 SW 2.0 140 – Workshop Service & Repair Manual

Peugeot 407 SW 2.0 140 Manual (2005) Troubleshooting & Maintenance FAQs

• Why do I hear clunking or creaking noises from the front suspension of my 2005 Peugeot 407 SW 2.0?

  Those pesky clunking or creaking sounds often come from worn suspension components, especially on older cars. A common culprit in your 2005 Peugeot 407 SW are the lower ball joints or perhaps the anti-roll bar links. For creaking, sometimes it's excessive friction in the upper front suspension joints. A mechanic usually checks these parts first, and lubricating those upper bearings after removing a friction washer can sometimes clear up creaking sounds. It's usually best to get it checked out.

• My dashboard warning lights (ABS, ESP, airbag) sometimes come on for no clear reason; what should I do?

  Ah, the classic "electrical gremlins" of the 407! It's pretty common for warning lights like ABS, ESP, or airbag to flicker on or stay lit even when there isn't a major fault. Often, this is down to a faulty sensor or perhaps a poor electrical connection. A good first step is to get a diagnostic scan; this might help pinpoint a specific sensor. Sometimes, simply cleaning and re-seating connectors or checking earth points can clear up these mysterious warnings, if they've been affected by moisture.

• Why might my 2005 Peugeot 407 SW 2.0 petrol engine be leaking oil?

  Oil leaks are quite common in these 2.0 petrol engines as they get a bit older. You'll often find leaks around the valve cover gasket or even the sump gasket. Sometimes, seals like those on the crankshaft or camshaft can start to weep. In colder weather, the crankcase ventilation system can also freeze, which increases pressure inside and can push oil out of seals. It's worth a visual check around the engine, especially near the timing belt front cover.

• I'm finding it difficult to engage certain gears in my 2005 Peugeot 407 SW 2.0 manual. What could be the problem?

  If shifting gears feels a bit stiff or imprecise, especially getting into first or third, it could be due to worn or stretched shift cables. While the manual gearbox itself is generally robust, these cables can wear down over time. In really cold weather, the manual gearbox drive cables can sometimes even freeze, making shifting tricky, but usually, they go back to normal once the car warms up. Replacing the shift cables often fixes this.

• When should the timing belt and water pump be replaced on my 2005 Peugeot 407 SW 2.0 petrol?

  For your 2.0 petrol engine, the timing belt is a crucial item, and it generally lasts a good long while. However, the water pump on this 2.0L engine has a plastic body and is known to be a bit fragile, prone to leaks after about 100,000 to 120,000 km. It's usually a good idea to have the water pump inspected and often replaced with every timing belt change, which is typically recommended around every 90,000 km. It saves potential trouble down the road.
