CLAAS 7738h – Claas Eng A15 Engine Module: Excessively High Temperature of Cooled Exhaust Gases

The temperature of cooled exhaust gases is excessively high, causing the engine calculator to reduce engine power by 20% per minute until it reaches 50% of its nominal power. Power is recovered at a rate of 20% per minute once the issue is resolved.
