Hi got diags run on car throttle body needed replacing. So swapped out . same
light re appeared on dash twice even after replacing. Car has 160000 FSH
no loss of power everything ok.

New fault code - 7859-p2015 intake manifold flap position sensor (bank 1) implausible signal
-mechanical failure.

This is exactly what's happened to me, the fix for this guy is unknown - the part marked blue in the post I believe is what has been replaced on my car -
throttle body.

Car has been serviced regularly and drives fine, and only other "history" to car is that it has had egr sensor replaced (I think) 20,000
miles ago and a forced dpf regen - 20,000 miles ago.

They have used a 3rd party throttle body from euro car parts but it's the same brand that audi use - vdo/siemens.

They also said they found excessive build up on intake manifold flap - "may require new intake flap or intake manifold" was their
comment

Further searching on another forum brings up this

Which would suggest I may need a new intake manifold.

or..

"The main problem is that the arm controlling the flap starts to jam hence the fault reading." - forgive my ignorance but I don't know which part is being cleaned
here - apologies.

The question I ask which I appreciate maybe difficult to answer is would it be likely that only 1 of the parts was
originally faulty, or would both parts (throttle body & intake manifold) of "gone" wrong at the same time.

Many thanks for any info.

Hi

I think the exact answer to my problem is intake manifold flap.

After having time to re-read all other posts and not being a mechanic my error code is identical to this

http://www.audizine.com/forum/showthread.php/54267...

error code - 7859 - Intake Manifold Flap Position Sensor (Bank 1) .

I will try and get the fix applied, but I am still curious as to whether a whole new throttle body was originally required.

Thoughts anyone?
