Well, The tensioner was shot. Got a new one, 20 minutes later got the new belt to tension to correct setting and went for a test drive.
It seems this chassis (124.034) has it's down sides and I've had the most common ones so far.
1. Brake rotors warping
2. Power steering resevior to pump leak
3. Poly Ribbed Belt Tensioner malfunction
4. What next ?
Anybody else got any commonalities we 400E owners should be looking for?
