Hi Guys & Girls,
Has anyone had similar problems on their 6r Gti's
Recently I had my rear warning taillight bulb come on, on my cluster checked all rear lights all working fine.
Turned ignition off & on-again warning bulb gone. Also tyre pressure warning came on yesterday upon starting and went off are few seconds, but the pressure is correct.
Today while driving the radio switched off and came on about 3 times while driving.
Got home about 3hours later had to go to the shops started car saw steering wheel warning on my cluster and steering was hard to turn like locked, Turned ignition off & on-again warning gone steering unlocked and could drive.

I did scan my car with ODB eleven tool and these are some of the Faults it picked up

Control unit: 02 Transmission
Faults:
P177F - Hydraulic pump motor Insuff. voltage
Intermittent i did have this error few months back i had a battery drain after sorted the battery drain and error went along with it.

Control unit: 03 Brakes
Faults:
U010100 - Lost Communication with TCM
Intermittent

Control unit: 09 Central Electrics
Faults:
00532 - Supply voltage Open circuit
Intermittent

Control unit: 17 Dashboard
Faults:
U111100 - Function limitation due to missing message
Intermittent

Control unit: 19 Gateway
Faults:
01315 - Transmission control module (TCM) No signal/communication
Intermittent

So it seems to me there is a Voltage Power/Earth issue's. could be Fuse's, Relays or Even the Alternator Regulator but unsure how to replace this.

can some point me in the right direction on how about to Fault find. and if you can share a Fuse diagram for the polo 6r GTI


Thanks in advance.




Thanks in advance.
Cheers
Preggz.

You need to know the battery voltage with the engine running without any load and then with as many consumers turned on that you can including turning the steering lock to lock to load the pump.

Hey Guys
Problem solved...
The main Power cable from the battery to the Distribution block was loose and had no nut so it was moving around on the bolt.
and giving me the low voltage Intermittent and insufficient voltage.

Big💪 Thanks to Crasher really appreciate all your advice and help..🤝🤝
