Broken honeycomb inside catalytic converter


Audi A4 1.9 TDI Catalytic Converter

The honeycomb inside the catalytic converter is broken (it is possible to hear this as it is rattling).
When the honeycomb breaks up, it can, in severe cases, block the exit for the exhaust gases and cause the engine to cut out .
The harmful exhaust gases are not reduced by the worn-out catalytic converter.

The importance of replacing C.V. Gaiters

On either end of the driveshafts on most cars today, there are C.V. gaiters (”boots”) which keep the special grease in the C.V Joint and the dirt and grit out.
(* “C.V. Joint” : Constant Velocity Joint)

These are made of neoprene in the main.
When the c.v. gaiters split, (as shown in the above photo ) as they would do with general wear and tear, the grease runs out, leaving the c.v. joint vulnerable to becoming dry and the bearings inside the joint breaking up.
To prevent this expensive replacement, it is less expensive in the long term to replace c.v. gaiters and re-pack with fresh grease before the joints run dry.
