cat replacement

[deejaymrt]

Hi eveybody i am a new member to this club and hope somebody can help me.I have a 2008 is 250 which has the error code p0402 after taking it to my local garage which i have been using for many years they have scanned the car and found they need to replace the cat.Trouble is they are saying its a massive job which includes taking off the manifold,taking out the streering rack to get to the cat. Does that sound right or are they taking me for a ride,i have read so many different things on this forum i am now so confused

So far I have not heard of cat failing on IS250, but I am happy to be corrected and considering that early cars are now 13 years old I would not be that surprised. I would guess it to be bad sensor rather then bad cat. In IS250 there are 4 cats, 2 pre-cats and to cats at the bottom, so if they planning on replacing pre-cats it would be difficult job - not sure if steering rack needs to be removed, but maybe that is part of accessing manifold.
