The emissions air injection pump can seize, causing a loud squealing noise followed by smoke from the drive belt. If the engine is not turned off, the belt will break, turning on the alternator/battery warning light.

Mercedes-Benz 300TE 4MATIC Problems
Squeaking/Worn Brake Pads May Require Rotor Replacement Also
Brakes --
Verified
Due to the size and material used on the brakes of these vehicles, the brakes may start to squeak around the 50 percent wear point. The brake rotor surfaces become uneven, causing a lip to form at the outer edge of the rotor. Because of this, the rotors are usually replaced when the pads are worn (pad life varies depending on driving style and terrain).
Engine Oil and Coolant Leaks Resulting in Fulid Intermix
Engine --
Verified
Internal and External engine oil & coolant leaks can develop from the head gasket and/or timing cover gasket; these leaks should be repaired before the engine oil and coolant intermix which can result in severe engine damage.
Transmission Oil Seals May Leak on High Mileage Vehicles
Drive Train --
Verified
High mileage vehicles may develop a leak from one or more of the transmission oil seals.
ABS Modulator Failure Due to Dirty Brake Fluid
Brakes --
Verified
It is not uncommon to encounter premature failure of the anti-lock brake system (ABS) modulator assembly due to dirty brake fluid. Our technicians recommend flushing the brake fluid every two years in order to help prevent this problem.
