The weight of the B6294S engine according to the catalog is 172 kg. The engine number B6294S is located at the junction of the block and the cylinder head. The main issue is the temperamental electronic throttle from Magneti Marelli. The second most common complaint on the forum is oil leaks from the variable valve timing system. Another frequent occurrence here is lubricant consumption due to a clogged crankcase ventilation. It is necessary to monitor the condition of the timing belt, as its failure can cause valve interference. Weak points also include engine mounts, thermostat, water pump, and fuel pump.
