So last night I decided to take off the engine cover and inspect the air filter as some guys have told me it's a mission and most dealershits and workshops don't replace the filter...
Engine cover off
The engine cover's sound-deadening sponge material has disintegrated and has gone in between the intake manifold...
Eventually I got the air filter out, it was filthy
Inside of the filter housing, not too much debris in there, just lots of dust...
And a shot of the MAF (or at least I think the MAF would be behind this screen?)
Here is a shot (with flash) of the filter with the sponge removed. The spongey cover was full of dust, so I chucked it. I hit the filter itself with my hand to get most of the dust out.
And a shot of the filter without flash. I wonder at what mileage it was replaced, I haven't seen an air filter look like this in years.
So tomorrow I'll do a complete service with new filters and fluids. If time permits I'll do the CDV delete and flush the brake/clutch system while I'm at it. Apparently the car was serviced before I took delivery, the pollen filter looks new, but I'm not gonna trust that the oil and filter was changed seeing as the oil level is at the minimum mark.
At least I'm getting the car sorted out now rather than later.
Oh and I cleaned the MAP sensor as well...
