[Beany1]

Getting around 100 miles on 20 pound diesel is that about right on city driving

Yes I'd say that's right. All depends on what fuel you're using. Ie shell costs a lot more than Tesco for example.

I always use costo premium diesel .. around 1.70 a litre

Hello Beany,

If you are buying your diesel at £1.70 a litre ( that’s really cheap Steve - close on, and above £1.80 here)  then you are buying 2.6 gallons for your £20. If so, your mpg works out at about 38.5 mpg. If your diesel costs you more, then you are obviously getting a better mpg than that. 
Kind regards,

Gareth.

It's fine. My daily only gets 34mpg.  And the Audi far less than that on short journeys.

Thanks steve

My car vibrates and shakes when engine temp get warm around 70 to 90 degrees when engine cold its smooth what could be problem 

[Beany1]

You can feel the car shaking and you can feel it through seats but idle is not bouncing about the needle is steady

Steve Y should be able to make more valid suggestions, but might include possible injector problems?? 
Kind regards,

Gareth.

[Steve Q]

Could be an injector, cam sensor. I'd advise a diagnostic check. Did you change the engine mounts as discussed in your other thread? 

[Beany1]

I've changed the snub mount and the driver side mount steve but not changed the driver side yet with sensor on it could mounts be problem only vibrates when engine warms up not on cold engine 

[Beany1]

Will any injector cleaner help with injectors something like millers diesel eco or something

[Beany1]

Thanks gareth for your input appreciated

[Beany1]

Thanks steve too appreciated

Yep try injector cleaner. And a diagnostic check. Could be a cam sensor. 

[Beany1]

Are cam sensors expensive will try some cleaner too 

[Beany1]

Is it the camshaft position sensor

Yep that's the one. There will be a couple of sensors. 

[Beany1]

Is it easy to change and do you know where its located

Hi if its not missing and the revs are stable it is most likely the mount you have not yet changed, camshaft position sensors are very reasonable as its an older model and they are a pretty easy fit.

The reasoning behind the engine mount theory is if you think about it when the engine is cold the oil in the mount is cold, therefore when the engine warms up so does the oil in the Hydro mount which makes the oil thinner, as Steve said get it checked for codes and have a look at the old mount to see if its spat its oil out.

Ye makes sense did have a look at the passenger side mount the one with sensor does look like its got a little crack does it mean when it gets hot the oil gets thin and gives more vibration and yes there is no problem on the revs its stable just under 1k is it good idea to check if my snub mount is centered and not touching the snub mount cradle will that cause vibration too thanks

The snub mount should be centred in the shroud as it doesn't bear weight. It's there to limit vertical movement.
