Two Fault Codes

[Imran]

Hi All.

Got an EML come on today.

According to VCDS its

008213 - Intake manifold Position Sensor (bank 1)
P2015 - 000 - Implausible Signal - Intermittent - MIL ON

Ive cleared the code and its cleared, erm, any idea what the code means? Read the ross tech wiki, some say the sensor is built into the manifold so have to change the entire manifold, some say check the wiring, Im going to get a friend to look at the wiring next monday when he has some time. Anyone have an idea how much a replacement sensor costs? Will check to see if the light comes on again if it doesnt wohoo if it does then

Also, recently, my climatronic has just started coming on by itself?!?!? driving along, feel heat look down and what the! climatronic is on. Its done this about 7 times now, only seems to do it when the car is warm or if i leave my hand on the gearstick when driving (which i tend to do)

According to VCDS its

01592 - Air Quality Sensor (G238)
014 - Defective

Again reading on the web, some say check your pollen filter and some say change your climatronic panel. Any idea where this sensor is located? Anyone have any ideas about this code?

Any help is appreciated
