I bought my golf 2 months ago - the garage is now saying it needs a new catalytic converter... how long does it take to 'brake'? I am thinking they sold it to me with this fault already there. The engine management light has been on twice for different things. It is a 52 plate. Will the cat. converter have been less that 100% for a while?

my corsa sxi is 4 years old and all i`ve had to get replaced...so far, is the back box !!
if the ngine management light has been on what were the causes? to damage a cat that is only 4 years old you must have been running the engine very rich.

The first time, the temperature sensor, so not too serious, second time was when they suggested that the cat. converter needed replacing. This was through a VW approved dealer. I've only had it 2 months - can I take it this has probably been sold to me with this as an existing problem?
a temperature sensor can make the mixture to rich and cause damage to the cat. (how long was it run with faulty sensor). & yes i would say that you were sold a duff one

The temperature sensor fault - I wasn't using the car to be honest and only had to drive to the garage when they could fit me in so I wasn't using it. The temperature guage was on cold all of the time, and having just got rid of my MG with a dodgy temperature issue decided that I shouldn't use it! I have come to the same conclusion - just going to phone the garage now!
thought you mean't the air temp sensor.
all the best hope you get it sorted.
