Febi has said it has the solution for common problems associated with the SEAT Leon.

Slow response behaviour during load changes and gradual loss of power may be signs of a faulty diverter valve, according to Febi.

It’s a problem that affects the SEAT Leon among other models.

A Febi spokesperson said: “The diverter valve (DV) ensures a rapid drop in pressure on the compressor side to prevent the turbocharger being slowed down unnecessarily if the throttle flap closes suddenly – thus reducing the “turbo lag” effect.

“The old version of the valve has a rubber diaphragm which can cause the unit to fail.

“The full charging pressure is no longer built up as air is pumped in a circuit even with the throttle flap open.

“If the brakes are suddenly applied at high speed and the throttle flap closes, the valve’s slow switching times prevent the dynamic pressure downstream of the compressor from reducing, which consequently creates the turbo lag effect.

“This not only results in the unnecessary slowing down of the turbocharger but also places an enormous load on the closed throttle flap.”

Febi recommends replacing the diverter valve with the most up-to-date component (Febi 39245).

As a piston version, it ensures that the valves function perfectly.

The SEAT Leon was first introduced in 1999 as the breakthrough car for SEAT.

It heled to show that the brand was capable of building cars which could challenge other popular hatchbacks such as the Ford Focus and Vauxhall Astra.

The Febi product brand is part of the Bilstein Group, which also incorporates the strong SWAG and Blue Print brands
