Problem Resolved!! DTCs not supported by controller or a communication error ocurred

[DPJ]

My (regularly Vag-Com'd) Leon has been sitting covered in snow for much of the last month and has only moved two or three times.

This morning I went to clear the eml (Probably the (non-existent) Secondary air fault) and I got

DTCs not supported by controller or a communication error ocurred
on
01 Engine
17 Instruments
19 Can Gateway
56 Radio.

( I got excessive comms errors on Auto HVAC and Central Convenience)

The only one it would actually read is 03 ABS.

Car runs fine, but laboured to start through flatish battery.

I've got 12.2 volts across the battery terminals now.

I'm thinking I've got a damp/condensation problem - or lower voltage somewhere else.

Should I measure the voltage elsewhere?

(I've used my cable and vag-com on other peoples' cars over Christmas/New Year without a hitch.)

Might be worth taking it foe a spirited drive to get some heat inti the car to drive out any condensation/damp thats sitting around.

 

[DPJ]

It had two 15 min runs today. I'll use it tomorrow a bit more and see if there's any change.

 

[Damoegan]

Measure the voltage accross the battery tonight then again in the morning before you start it just to see if anything is draining it.

Doubtful. Although it's nearly an 8 year old battery, it just hasn't had enough running to charge it recently considering winter usage, lights on etc etc. I'll try though.

Car started fine this morning. No improvement in vag-com usability after a good run.

If anyone from Ross Tech is reading this.....

I'm getting G71M = -1 repeating itself in the comms box on the screen.

 

[DPJ]

I'm starting to think I've got a problem with OBD, either centrally (socket?) or one of the modules is affecting the whole system.

(Note I'm certain the eml was originally secondary air related as the light came on the day before the snow hit in usual circumstances - I clear this code regularly)

I don't really know where to start looking - other than to check the connector to the engine module (when the weather improves), and to check the connectors on the back of the obd socket.....

Anyone know where the Can Gateway is?

 

[Damoegan]

Have you tryed anyone else's vag-com just to be sure, Dave?

 

[DPJ]

I'll check mine on KiwiCupra when I've a minute.

 

[Damoegan]

I can meet you one day through the week if you want to try my vag-com mate

Have you got a Bammer now

Cheers, I'll let you know. You've spotted the avatar, then.

...You've spotted the avatar, then.

 

[DPJ]

Well, gave it a good run out today - maybe 80 mins with aircon running as temps are 7.5 degrees - so I'd think all condensation has gone inside.

Vag-com on - same problem.

Vag-com into KiwiCupra..... same problem.......................

I think my lead must be goosed.

 

[Damoegan]

You want too meet up and try mine, Dave?

Or I could stick mine in the post for you?

That's kind of you.

I've bought another one, should be here Tue/Wed.

Well I haven't sorted this.

Replacement USB lead arrived and the problem is exactly the same. Tested on Leon. Not yet tested on Ibiza.

I can get Unisettings to work fine.

It's almost as if my vag-com (or rather my laptop's handing of Vag-com has gone 'flaky'. I've tried disabling everything that's running, made sure my USB ports are always on, etc.

Vag-Com seems to take ages to respond. As said, I can only access ABS (Is that a different protocol?)

Accessing 01 or 17 takes a while, then once in the controller, the bottom buttons fill, then blank out, then fill, all while the Vista timer is running. (see blanked out in screen dump below)

Can I reinstall vag-com without losing my licence?

(As said previously, used vag-com no probs about 2 weeks ago).

 

[Damoegan]

Do you not have the licence key, Dave? Then you could reinstall.

I'm free today to pop up if your stuck...

 

[DPJ]

Yes, I've got the licence key.

It's not earth shatteringly urgent, just a matter of getting it working. I can test the new lead on KiwiCupra - I can even test it on the Bammer on Friday.........

I know Unisettings is a small prog compared to Vag-Com, but you wouldn't expect it to communicate smoothly and fine with the ecu if there was an obd prob with the car, would you?

 

[Damoegan]

If Unisettings is working then I wouldn't think there was a problem with OBD.

I'd try a reinstall of vag-com.
