Peugeot 406 Coupe

In 1995, Peugeot replaced the successful 405 with the more modern 406. Its shapes are still elegant, unlike the later 407 with a monstrous bumper hole and a giant front overhang. The 406 is still an example of a classic sedan and wagon. The Peugeot 406 Coupe debuted in the fall of 1996. Italian designers from Pinanfarina worked on his appearance. The platform, of course, borrowed from the sedan, but has undergone numerous modifications. The body is distinguished by arches of the front wheels, rapids and body racks. The original spare parts are getting smaller every year. The list of proposals is especially narrowed for body parts. Unfortunately, the secondary production of body elements is practically absent, which can complicate possible repairs after an accident. Some parts will have to be searched for in the squash. Some details are only present in the catalog, and there is no real possibility to order them. For example, the 1999-2003 front bumper version is still available, but the foam blocks located between the metal amplifier and the plastic case can no longer be ordered. The same applies to auxiliary fasteners. Fortunately, the headlights can still be purchased. Sometimes you can see specimens equipped with xenon lamps. It is worth noting that the 406 coupe was never equipped with xenon light, only a pair of H7 lamps installed in lenses. Xenon is probably an attempt by owners to solve the problem of the standard halogen’s dim light.

Engines

At the time of appearance, the handsome coupe was equipped with a pair of gasoline engines. The main was a 2-liter 4-cylinder XU10 with a capacity of 135 liters. with. This series of engines was produced since the 80s. Conceptually, this is a “square” engine with equal diameter and stroke of the piston 86 mm, as well as cast-iron monoblock cylinders. The unit is reliable under the condition of regular oil updates. Otherwise, there is a risk of contamination of hydraulic valve pushers. Periodic maintenance requires and drive valve timing with a geared belt. In the fall of 1999, the 2-liter XU gave way to the new EW series unit. the 2-liter engine received an aluminum block and began to comply with Euro-3 emissions standards. His size has changed, too. The concept of the “square” gave way to the “super square” (long stroke of the piston) with a cylinder diameter of 85 mm and a stroke of the piston of 88 mm. Increase in power by 3 hp almost played no role, and the maximum torque increased from 180 to 190 Nm, while shifting the peak from 4200 to 4100 rpm. The new engine is better, but more problematic. Sometimes he starts consuming butter. Fortunately, the alert sensor alerts the wearer in advance of the danger. The problem is also cold starts, when the engine "troubles" and stalls. The reason is a constructive miscalculation. Engineers used too small hydraulic pushers that quickly clogged. The evolution of the 2-liter EW10 was the four-cylinder 2. 2 EW12. The diameter of the cylinder increased by 1 mm to 86 mm, and the stroke of the piston increased significantly - to 96 mm.

Transmission

Owners of old 2-liter cars with manual transmission often face the problem of gear shifting. We are talking about the 5-speed mechanics VE3, used until the autumn of 1999. Lever in the curtain over the years acquires more and more backlash, which affects the accuracy of the choice of gears. The situation is caused by wear of plastic bushings of three levers of the mechanism - two short and one long. Replacing won’t be expensive, but there’s a catch. As original spare parts, Peugeot supplies only a long rod, short ones are no longer available.

The six-cylinder engine was also combined with 5-speed mechanics, but the more durable one was the ML5T. The movements of the gear lever are incredibly accurate and smooth. A pair of cables is used in the gear selection mechanism. A possible backlash of the lever will indicate a large mileage. The ML5T’s weakness is a hydraulic clutch drive that can leak. ML5 got and 2.2 16V.

Most often, a six-cylinder atmospheric was combined with an automatic transmission of a planetary type. There were two machines, the AL4, developed by the French in collaboration with Siemense, and the alternative ZF 4HP. Both boxes are 4-speed, and you can determine which one is installed by punching a VIN number in the Peugeot service system.

The identification of automatic transmissions is very important, as AL4 is very problematic. With age, it increasingly falls into emergency mode. The cost-effective repair of replacing electromagnetic valves will help for a short time. To get rid of the disease will allow the replacement of the entire hydraulic unit - more than 50 000 rubles.

Walking

The brakes of cars with a 6-cylinder engine are much better. Brake discs are larger, and four-piston Brembo calipers are installed on the front axle.

Over time, the eccentricities of the rear axle levers sour, which causes difficulties with adjusting the geometry of the wheels.

The ball support of the front levers has an unusual design. It is positioned in a swivel fist and inserted into the lever, not vice versa.

Typical problems and malfunctions

Sometimes the cooling fan starts working at a reduced speed. The reason is a faulty control relay.

From time to time, the control lamp of the airbag lights up. This often happens after a chair is moved due to poor contact in the connector located under the seat.

With age, the plastic cover of the front passenger airbag deforms. It was installed until the end of 1999 in the D8 version. Many people think that the pillow worked, but it did not. The cover as the original Peugeot detail is no longer supplied.

The Peugeot 406 Coupe uses frameless door glazing. Taking up the handle, the glass should fall a few millimeters, and after closing the door - should rise again. During the inspection, the system should be checked during the process of repeatedly opening and closing doors.

In conclusion, it is worth noting a fairly good protection against corrosion. Yes, Pinanfarina did glorious bodies in every sense.

Model history

1996 – In the fall at the Paris Motor Show, the debut premiere of the coupe version, known as the D8, took place. The car was produced by Pininfarina, who developed the beautiful exterior shapes. Engines: 2.0 16V 135 hp and 2.9 V6 24V 190 hp Boxes: 5-speed mechanics or 4-speed automatic. 1997 - spring sales began in most European markets. 1999 - autumn model was updated and received the designation D9. Changed the control panel climate control, and the button on the alarm moved above - to the place of the clock. The front passenger airbag no longer has a visible cover. The level of equipment has expanded, the steering wheel has slightly changed. A new all-aluminum engine 2.0 16V of the EW series with a capacity of 137 hp was proposed, corresponding to the Euro-3 standard. 2000 - the six-cylinder engine was updated. Its new designation is ES9 J4S. Power increased to 209 hp, and a regulator of gas distribution phases appeared on the intake shaft. Each cylinder was now entitled to a hotel ignition coil. The engine complied with Euro-3 emission standards and received four catalysts and four lambda probes. Limited Series Settant'anni. 2001 - in early June, a multiplex electric network was introduced. 2002 - the range of engines was replenished with 2. 2 16V 160 hp and 2. 2 HDi 133 hp. A limited edition Black and Silver was offered for some markets, and 2003 was another upgrade. New front bumper with a large intake hole, similar to the newer Peugeot 407.

• On foreign forums from time to time there are tips to solve problems with the launch of EW10 by replacing pushers with analogues from 2. 2. It's hard to say if that will help.
• When one of the coils fails, the electronics cannot determine which cylinder is not working.
• Its 4 lambda probes often contradict each other, which is accompanied by a tanning of the engine malfunction indicator, and then loss of power.
• It was always equipped with a particulate filter, which usually does not cause problems.

Shows, bargaining and re-registration take time: buyers look, promise to think and disappear. Fair price after inspection closes the auction on the spot. If money is needed urgently, the purchase takes away waiting and repeat displays.
