Help Needed With Vag Com Fault Code Meanings/ How To Fixes Please

[Ben g mon]

Hi, could someone decode what my vag com disc has flagged up please?

 

Auxiliary Heater;

code 01414 combustion air blower (v6)

36-00 open circuit

 

Auto HVAC

Codes;

01189 front air flap motor v145

009 open or short to ground

 

00926 terminal 30,

002 lower limit exceeded

 

01271 positioning motor for tempreture flap v68

009 open or short to ground

 

Fit confused by this as the heater set up is manual.

My Galaxy is 2003 zetec 1.9tdi PD engined

 

Got the parking sensors working, got to go very close to set them off however!

 

Hope someone can point me in the right direction with this!!!

 

Cheers...

The terminal 30 - 002 lower limit exceeded is often triggered by low battery voltage, either been flat or battery has had it. Other random fault codes with this not uncommon.

 

Clear the faults and see what comes back. If you can clear the terminal 30 - 002 lower limit code and the multiple faults around the heater controls come back, you have to check fuses and for possible earthing faults behind the dash.

 

Not sure about the aux heater, my petrol doesn't have one, but could also be connected to low voltage issue.

Bit of an update;

 

Cleared codes mentioned in above posts, all returned after 20 min drive.

 

All related fuses checked and ok

 

Looked into HVAC fault codes and seems to be inside dashboard area. The

blowers ,recirculated air and air director (dash, windscreen, floor) operate as needed as does the air con when turned to cold and put on full power.

 

The air con does light up i don't hear it power up

and have been told it's got a leak in the system but I can't see where! No fault codes are showing for the air con is anyway of testing things there?

Have extensively read up on air con faults here and can see no broken pipes etc as yet....

 

Mk2 TDI 1,9 set up if it makes a difference

 

Cheers for who has replied.....

Did the terminal 30 error return?

 

If so have a check of the battery voltage with a voltmeter as the first step both with engine running and stopped.

 

Air con gas will leak out of the smallest hole - the only ways I've ever found them is either by seeing the leaking dye (they should put a yellow dye in the oil to make it more noticable) or by hearing the gas escape and tracking the source. A missing seal is also enough to cause a leak that may not be immediately obvious where its coming from.

Hi,

Yes terminal 30 error returned, I'll check the battery all the same, have not had any starting problems or anything either.

 

aux heater also flagged up the same fault 5 times in one scan! (Same as last time)

 

I'm more wanting A/C working as its like an oven inside, coldest setting smells like gym kit with A/C off.

 

Is there any setting in vag com to see if air con fires up? Can't see an option for it.

[BrianH]

Solve the battery problem code first - It might start and run ok, but if its not getting the expected voltage it can cause a few wierd symptoms (ecus don't always behave properly so can cause all sorts of spurious errors without the right voltage to start with) - once you've got rid of the terminal 30 message you stand a chance of sorting the rest - some of them may disappear at that point if your lucky.

 

And yes, with all that glass its like a mobile greenhouse, I've found opening the rearmost windows does help a bit though (the pop out ones)

[sparky Paul]

I agree, as BrianH said, and I said in post #2, you need to sort out the 'terminal 30' problem FIRST. This is a battery voltage problem. Even if the car is starting okay, the battery still needs to be checked out or substituted for a known good one, you may have a cell down.

 

It's not uncommon to get other random faults popping up at the same time.

Ok, I'll get the battery changed (be good to have a spare, using the old one as a slave) and clean up and grease up the terminals and work from there.

 

Anything special about these batteries?

I think it's just a standard 096?

 

I had a grand voyager with endless battery issues so was glad to be past that when it was served on.......

Bit of an update....

 

Changed the battery for the larger 019 as mine looked quite a bit smaller and terminal 13 fault code and the auto HVAC codes have vanished even after 3 scans a short drive and a re scan!

 

Only fault code is 01414 aux heater open circuit which I'm guessing is just the underfloor heater glow plug fault? I'll save that for the run up winter if so..... Just air con to play with now.... Can't see anything obvious yet.......

 

Thanks guys for your help

Whoops I ment terminal 30 and auto HVAC codes have gone.......,

Glad to hear it - I know it sounds crazy, but your not the first to find that sort of issue with a dying battery. Theres many postings on here about the aux heater, I don't have one personally but your moving in the right direction now.

 

just leaves you with your leak to find - Which unless its any of the common issues (broken pipe common on some varients mentioned before) will be a case of trying to fill it and see where it leaks out from. Might be worth a ring round a couple of the air con places to see what they can help with as your pretty much stuck if they say theres a hole its a case of locating it (likely areas for damage are the condensor next to the radiator - stone chips can puncture it, otherwise its where its either been taken apart previously and not put back together correctly, or if something has rubbed against the pipework it can wear a hole over time (generally should only be the case if something isn't in its correct position for some reason - loose brackets, loose hoses, etc are all able to do this given long enough) Or it could be a split in the rubber hoses (its unlikely to be a seal if they detected it under the vacuum stage, more likely its damage of some sort, seals tend to show up more on filling or under use from what i've seen)
