Fault codes.

[ScottD3]

Engine management light came on last weekend but went off the next day.
Did a scan yesterday and found some new codes.

I've removed the standard codes of fault handles, buttons and footwell heaters.

Address 69: Trailer Labels: 4E0-910-383.lbl
Control Module Part Number: 4E0 910 383 C HW: 4E0 907 383 C

1 Fault Found:
02539 - Terminal 30 from Control Module
006 - Short to Plus

This keeps coming back instantly.
I've used tow bar and electrics with no issues. It all worked fine.
I checked the wiring and it looked fine.

Address 01: Engine Labels: Redir Fail!
Control Module Part Number: 4E0 910 401 Q HW: 4E0 907 401 C

2 Faults Found:

005658 - Glowplug for Cylinder 1 (Q10)
P161A - 001 - Open Circuit


012597 - Intake Manifold Runner Control
P3135 - 001 - Lower Stop not Reached - Intermittent

Glow plug is an old one and before the weather turns and I can't get out there, I think its time to get it fixed.
Is it normally new glow plug?

I think the intake manifold runner control is was cause my engine managment light to come on. I've not seen it before.

Anyone got any ideas?
Its not come back since.

Address 28: HVAC, Rear Labels: None
Control Module Part Number: 4E0 910 158 HW: 4E0 919 158 A

1 Fault Found:

00003 - Control Module
003 - Mechanical Failure - Intermittent

This is a new one and I hate it when it says mechanical failure.
I got no idea what it is talking about.

Address 34: Level Control Labels: 4E0-910-553.lbl
Control Module Part Number: 4E0 910 553 H HW: 4E0 907 553 F

2 Faults Found:

01577 - Turn-Off due to Over-Temp
001 - Upper Limit Exceeded - Intermittent


01772 - Signal from Level Control Pressure Sensor (G291)
008 - Implausible Signal - Intermittent

I'm going to rebuild the pump this weekend with bagpippingandy kit. Hopefully that will stop the two fault codes.
I assume they came on cause of the piston ring aging?

Not seen this before.
Battery has been fine. No issues.
