A query to a fellow Pinner resident. My 4 has developed a constant ticking noise from the engine compartment, like a busy sewing machine my wife says. Does not affect performance, but is tiresome to use. Tappets checked. Any ideas?
Could be any number of things-a broken timing chain tensioner, a segment in the dynamo commutator come loose, bonnet release spring and plunger rattling, bonnet hinge pins loose and rattling. Water pump pulley loose on the pump shaft. Grille not secure.
Put the question on the forum and more minds will address it.
