06 1.4 Polo

[Imran]

Hi all

Done a scan on wifes polo, and the following code always comes up regards to engine.

Address 01: Engine Labels: 036-906-034-APE.lbl
Part No: 036 906 034 KA
Component: MARELLI 4TV 7448
Coding: 00071
Shop #: WSC 00000
VCID: 5BBF89B5C93EA11
WVWZZZ9NZ6Y178787 VWZ7Z0E2811296

1 Fault Found:
17961 - Barometric / Manifold Pressure Signals
P1553 - 35-00 - Implausible Correlation
Readiness: 0110 0101

From what ive read could be a number of things. Eith MAF sensor, or throttle body needs cleaning, or some say check the timing belt tensioners they are plastic coated and the plastic coating can come off which puts the timing slightly out causing a code.

Any ideas?
