Hi, I just bought a 2006 159 and it has various faults. I'm wondering how many of these I can get advice on from the forum. The car has 83k and is a 2.4L Lusso.
The faults are:
Humming sound coming from bulk head, very random, will stop if I rev to 4000 rpm, but then comes back in a matter of seconds or minutes or stays off, very random except will turn off when I rev.
Water coming in through the front left dashbpord vent
Gear change very stiff and clunky, have to change gear very slowly
When I start the is an error message on the dash saying that the alrm is not available (and the alarm beeps twice when armed)
The clutch pedal is much higher than the brake pedal and makes clicking sounds as it rises above the brake pedal
The last one/three issues which I think may all be one issue, (1) the tickover is lumpy, especially after driving hard, and (2) the smell of desiel fumes fills the cabin all the time and once when ticking over a load of exhaust smoke came from under the front wing and (3) the fuel economy is poor. I have driven it very nicely on roads where my other cars will easily achieve their combined fuel economy but I cant even get close. The previous owner left the trip computer with 3000 miles averaging 35.7, but I can't even get more than 33mpg. It should be 42 mpg.
If anyone can help with any of these faults I'd really appreciate it. I have bought an elm327 v1.5 and bluetoothed it to phone using an app called torque pro, and this says there are no fault codes on the ecu.
