Where is the MAP Sensor located??

Hello guys!
I am having some issues with my 2001 1.4i AUA A2. Sometimes the car doesn`t want to rev up and has no power in the 2nd and 3rd gear, and the engine is shaking in idle. I have already changed the throttle actuator, the oxygen sensor from the front of the catalityc converter, I have cleaned the EGR valve, and changed the spark plugs, but the problem still appears sometimes and its not intermittent. I want to check also the MAP sensor, but I don`t know exactly where it is located. I have found a thread from 2014 (https://www.a2oc.net/community/index.php?threads/p0106-fault.24045/) there is a picture from the MAP sensor, but it is not really clear where the location is. Can anyone send meg a picture where can you see the exact location?
The parts frome above what I have changed, were showed as faulty in the VCDS, and that is because I was changing them. Now there are no fault codes in vcds, but sometimes the car has these simptoms what I have described.
Does anyone had these simptoms? How did you solve it?
Someone said that it can be also from a clogged exhaust/catalityc converter.

Recommend use of vcds as a guide
But don't assume it is Gospel
Roughness at idle I would start with basics
Plugs which you have changed
Leads and coil pack
When removing the old plugs examine them for tell tale signs of poor combustion and replace them at regular intervals
Older cars generally suffer from lack of maintenance
Failure to swap plugs leads to high resistance and stresses the leads and coil pack

I have checked the plugs what I have changed and they had no sign of poor combustion.

Do you know where the MAP sensor is located?

Have a read of this old thread, may just have your solution.

If I'm correct its on the left hand side as you look into the engine compartment on the rear of the air intake pipe from the Air Filter. Around the Brake Master cylinder Area... Well it is on my BBY engined 1.4

I have found it, it was located on the left side of the engine when you watch it from the front under the air hose and near under that valve looking piece. I have marked it on the picture where the location is. I have cleaned it, and now it seems to be ok. I have also checked the hoses and there are no leaks. Hopefully it will help someone else, who is looking for the MAP sensor.

Sorry Ballallevi my advice was misleading, I assumed yours was a Right Hand Drive. I'm glad you found it and hope the fix holds up.
