I just want to pick your brains please. My E46 320cd has a couple of issues.
So the symptoms:
1)Fuel economy shown in car @ 33.9mpg and I tried to drive the right way to improve it.
2)Temp gauge never reaches 12 o'clock
3)Temp gauge takes a long time to climb out of the blue
4)Idle is a little rough though it doesn't hunt
So a little history. The car has 141k on the clock with a full bmw service history. I bought it 2 weeks ago and it seemed Ok then. Last week I did a couple of bits to it. I gave her a decat downpipe and pipercross filter. I also decided to get rid of the egr valve. This has shown the EML. I'm lead to believe that this is normal on my car.
And what have I done. Well after traipsing through various forums I decided to change the egr stat. When I took the old one through I could blow through it no problem. Once I had the new one on I went for a drive to see what might have changed. I drove it as I normally would through a mix of roads and covered about 30 miles. Now that I am home again the new economy figure is 44.5 so that's probably about right. The temp gauge climbed up to the white line at a decent pace but still didn't go to the 12 a'clock position it just hovered above the line.
Any thoughts on all this would be great thanks guys
