It's now had a starter motor and things are back to normal. On the subject of MPG I've been doing a little digging on the government's website:-
Code: Select all
Car Urban Extra Urban Combined
C5 2.2HDi Auto 28.8 51.4 39.8
C5 2.0HDi Manual 36.2 56.5 47.1
Skoda Octavia 1.9TDi Manual 41.5 65.7 54.3
BMW 320d Manual 36.2 62.8 49.6
BMW 320d Auto 31.0 53.3 42.2
It would seem the C5 2.2HDi Auto has never been known for good fuel economy...
Indeed the 2.2 has always had a poor reputation for economy but the above figures have two omissions viz a 2.2 manual and a 2.0 auto, I suspect that those details would put a slightly different perspective on it and ensuring that it was an estate not a saloon as the estate is heavier than the saloon.
The 2.2 manual estate is a rare bird hence most of the complaints about the 2.2 are for the auto version, similarly the auto version of the 2.0 was not so common as the manual so again when people say the 2.0 is more economical it is but maybe not by so much.
One should compare apples with apples
Having said that even in manual version the 2.0 litre is nowhere near as good as the VAG 1.9 in the Octavia and I can confirm that the numbers for the OCtavia are easily achievable and often exceeded.
Interestingly I have just done a journey which was essentially a 140 miles of Extra Urban at 70 + the economy was as near as makes no difference 39.8, however I am sure if I had reduced speed to 56 mph the economy would be better though I doubt it would have reached 51.4.
