Audi A4 Cabriolet roof problem -- Implausible Signal ---Help with signal codes please

[moveitnick]

I have had a major headache with this, i have replaced all the roof tray and components that are in the boot as i broke that. I have had a full VAGCOM rest done and when it read the code sequence for the roof open and shut it came up with this

OPEN
Address 26: Auto Roof (8H0 959 255 )

19:19:31 Group 001: Convertible Top Status (Actual)
Not Oper. Convertible Top Control Switch
00100001 Switches && Positions I
10 1010 Switches && Positions II
30.0 Top Frame Position (G356)

AND ALSO

CLOSED

Address 26: Auto Roof (8H0 959 255 )

19:13:35 Group 001: Convertible Top Status (Actual)
Not Oper. Convertible Top Control Switch
00011010 Switches && Positions I
10 1010 Switches && Positions II
138.0 Top Frame Position (G356)



Address 26: Auto Roof Labels:
Control Module Part Number: 8H0 959 255
Component and/or Version: VSG B6 CABRIO 6286
Software Coding:
Work Shop Code: WSC 00672 785 00200
VCID: F3E0C3AC91AE891
1 Fault Found:

02000 - Switch Position
008 - Implausible Signal




Now apparantly the code sequence for the first few digits on the SWITCHES & POSITIONS 1 are wrong

The first set should read

00101001 but reads 00100001 (open)

The second reads

11011010 but reads 00011010 (closed)

Please can someone tell me which microswitch or switches need changing if that is the case, many thanks in advance, Nick

I replaced the G356 switch on my cab.

It is a potentiometer locates in the main pivot point of the roof to body.

They have brought out a revised switch since mine was made

Part number:

Top Frame Position Sensor

8HO 959 613 A

its about £60 expensive for a switch, but i don't get any fault codes now.

This was my faults:
2 Faults Found:
02000 - Switch Position
008 - Implausible Signal - Intermittent
01986 - Convertible Top Frame Position Sensor (G356)
008 - Implausible Signal - Intermittent
