Electric Diagnosis - Error Codes

[GrizzlyUK]

Hi guys,

I've just had my car in the garage to figure out an ongoing battery drain issue.
If I leave the car for more than a couple of days, it'll be completely dead.

My mechanic let me take note of the error codes that came up, I was hoping that someone here may have come across some of them before.

From the looks of it, it's sounding like it going to get expensive - here are the codes:


- 17 Instrument Cluster
- 42 Driver's Door Electronics
- 46 Comfort System Central Control Module
- 52 Passenger Door Electronics


The car has recently been in to have some minor body work done, where the doors needed to come off, so those code 42 & 52 maybe relating to that.
17 & 46 seem to be the most concerning.

Am desperate to keep my golf on the road, so any ideas that I can suggest looking at would be really helpful.

Those are not codes. That's just the control units that have a fault. Each control unit will have 1 or more codes and description of the fualt associated with it which you can use to check for a fix online so what they've given you is pretty useless.

 If the doors came off with the battery connected it would fire up a code and it would just have to be cleared after. Also just to note most people have a few codes here and there constantly I think mine always has like 5 at least, but if they're not serious they don't necessarily need attention.

Thank you, I did think they were pretty vague.

I think I may have to go down the route of disconnecting the battery if I have to leave it for a long period.
Mechanically the car is sound, but its a nuisance having to jump start the motor every other week.

Hopefully the garage will narrow down this problem to something as trivial as a fuse and not need to take the entire instrument cluster out.
I can see that costing a fortune in labour.

Got the car back from the garage. They recorded a very high drain of 0.6.
Fixed the driver door wiring loom and the drain is now about 0.09, so significantly better anyway.
