2000 (W) 2.0 HDi Economy - locked thread. - ap306

Can a damaged cat converter decrease fuel economy?

i recently purchased a 2000/w 306 2.0hdi and found its givng me the same mpg as my previous 306 2.0xsi petrol, which was around 150 miles from 20 litres of fuel (100miles motorway and 50 urban), i am doing the same journey and getting the same fuel economy.

i have found that the cat converter is damaged (a loud vibration) and the front of the car had been lowered, can either of these effect mpg?...surely not by this much?

according to various sources (306 handbook and parkers) i should be getting approx 40% more mpg (average 306 xsi 31 mpg, 2.0 hdi 54.3mpg)

Sorry for re submiting this the other thread contained information about a HDi cutting out#

You're wrong, I went to a great deal of effort to separate the two threads yesterday, both threads are live and completely dedicated to the different problems. This one locked. Do a Forum search on your own alias if you don't believe me.
