Lupo electrical issue? or not?

[Jimmie77]

Ok since i written a few things about varoius issues on my Little car i sense theres a disturbence in the force. its a 2001 1.4 "AUA"

Ok first of since i got the car there have been 3 things from the start. 1: The passenger window didnt work though it clicked when pressing the button. 2: There was some liquid dropped on the windowbuttons on the driver side making it fused and burned. 3: A weird fault where the lights of the Engine and the EPC (i Think its that name) symbols show. Sometimes more frequent and sometimes less frequent. i managed to check it for codes and got this "P0106: Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem
P013A: Unknown code" and i got a airbag fault too wich i erased and it didnt come back.

Starting with the number 2 issue i removed the parts wich where melted and replaced it and it worked on the drivers side again. (also it made a flickering on the dashboard and a very hot dashboard lighdimmerswitch disappear go away suggesting it was getting faulty Power).

The 1st issue i solved by starting to take the hole door apart to getr to the Electric window parts. But when i removed half of it and tried it, it came to live once more. But now a few month later its stuck again. And when it worked it didnt act ok. When window came down it was ok. But on the way up it stopped in the middle and Went down again, and the it could be closed after that.

The 3rd thing. I cleaned the Engine and the piping to the umm air manifold? (i dont know the English Word for it). Well there was a lot of yellow gunk in there, and i cleaned it up and thought that might do the trick. And surely the lights didnt show its ugly shine for a while. But then they came back.

A few times (Before the cleansing) the car started with the lights and where like only drivable at 30kmph. But a restart made that go away.

And now we have more stuff. The button for recirculating the air or something (long button with a circle Arrow) stopped working more often than working.

The seats heating stopped working on drivers side and i havnt got it going again.

And a week ago the reverse lighting stopped working and after a few Days it magically started to work again.

No fuses are blown.

And one more thing. The error codes i got the first time didnt come easy. but after a few tries it worked. But that was a friend doing it. After that i got myself a Cable and program to check it myself. and thats the way i erased the airbag fault. BUT it refuses to read Engine codes no matter how hard i try!

Only other thing i changed is a pair of ABS sensors and that went well. lights came up showing error. And lights Went of when fixed.

One more thing is that the brakepedal feels weird, like if there where air in the system. pushing up and down a bit and the car shakes a bit. But that also do not happen everytime

Reason for bringing up ALL the things is that i cant let go of the feeling that there might be a Connection between all these things. Please advice me

No. From experience, i would say thet they are all separate things.... but i would have a guess that the inside of the car have got wet at some time, as many if those problems are often caused by wet contacts in switches. The engine and brake problems are different again...

The electrics in the Lupo and Arosa are really cheap. There are many things that can go wrong.
