Start Stop Error (64 Reg 1L Polo 6c)

Post by acanepe99 »

My Car:
64 Reg 60hp 1L Polo 6c BlueMotion

The Issue:
Auto Start-Stop Error displayed on start-up
Engine warning light on
3 Faults found when scanning with OBDeleven device (screenshots attached);
Vacuum Sensor (C10A301), Neutral Position Sensor (P15A100) and Invalid Data Received From Vehicle Dynamics Control Module (U041600)

I've done some research myself and found other posts that mention replacing the following parts;

1. Gearbox Neutral Position Sensor (Part 02T906207D)
2. MAP sensor (Part 03C906051F)
3. Brake boost pressure sensor (Part 5Q0906207)

but I'm unsure which one I actually need and some of them are expensive.

I know how to replace all the above sensors mentioned, just don't want to buy all 3 if I only need one.

Could anybody please advise how I can get this issue resolved as I'm looking to sell the car in the near future.
Any help would be VERY greatly appreciated!! If anyone wants any further info please let me know!

I'd start with fixing the two static errors and clear all DTCs. If the intermittent error also returns for the neutral sensor, replace that one as well.

MAP sensor take out, clean with brake cleaner or CARB cleaner, if it doesnt work its dead.
Also u can use fuel to clean it.
