I want to inspect the airfilter on my stilo as i have poor fuel consumption but can't find it.
where is it and how easy is it to replace the airfilter?
Can it be done on the drive way?
I only get 34 round town and 42 on motorway trip travelling 70 - 75 MPH.

Are you sure it is the airfilter that is causing the fuel consumption?

I know the previous owner lived on back roads and drove most of the time on them.
Therefore I wanted to check the air filter first as i thought this would be the cheapest and easiest place to start looking.
Any other suggestions that could cause an MPG drop on a JTD? or do these figures seem about right?
Car is only 2 years old and done 30k miles.

An easy check is to remove the MAF sensor connector (use Search if you need more info).

If the MPG improves then you most likely have a duff MAF.

Since it's a lot easier to change the MAF sensor when you change the air filter then I'd then change both at the same time.

If it doesn't improve and you want to change the air filter anyway then you'll need ramps or axle stands. Remove the undertray, crawl under the car, and prepare for a struggle :bang:

As Argo says - it's a pig of a job

Totally agree its a pig of a job, fancy putting the air filter under a car, not only that you have to remove the turbo pipe/breather that fits to the bottom of the filter which had oil dripping on the flloor and make sure you have a large jubilee clip to refit it back, not only that you need octopus arms to get the filter out and back in, what takes about 10mins max on most cars took me over an hour and a lot of swearing. PS didn't help with consumption after all found to be the MAF.
