Hi Folks, 

Looking to try and rid the old girl of some codes, most have been present for as long as I can remember, but have been ignored as they've never had any noticeable effect on the vehicle.

I currently have 5 codes

 

P0101-Mass or Volume air flow "A" Circuit Range/Performance (has had a new MAF however Its non genuine and I belive is still causing the code so will be swapped for a genuine and see if that makes a difference)

 

07330-Manafacturer Specific Code

(Struggling to find any reference to the definition of this code?)

 

9481988-Air quality sensor- internal system fault

(Just awaiting a new sensor)

 

9458449-Manafacturer Specific Code

(Looks like a celluar antenna fault?)

 

02256-quiescent current

(Most likely the 12v charger that is plugged in all the time, never bothered to look further as I've never had battery drain issues)

 

Scanned with an old Carista bluetooth obd2 reader.

 

The two that I'm focusing on at the moment are the undefined code 07330 and the Cellular Antenna.

 

I've done a fair old trawl through Google and I really can't find much on 07330 only one site seems to reference it ;

"07330 Description And Summary :
Diameter in engine evaporative emission system switching valve control, circuit low It could be due to limited air getting through your air intake shift lock, open and exhaust gas temperature sensor bank 1 sensor 1, circuit intermittent will delay your vw fault."

 

How accurate this is, im not sure.

 

Otherwise there's the antenna, which is what I've dug into today,

Now I'm not familiar with the bolero/columbus units, their options and extras.

All I can tell you is that as far as I'm aware my car is still as built from factory, it has a non navigation bolero unit, a shark fin antenna and a 5NO prefix Bluetooth module which does have a purple FAKRA connected to it, which I understand to be the GPS Antenna (presumably in the shark fin?)

However I have no radio reception issues which in other posts I have read would suggest that the shark fin is not at fault? 

I've read through so much on the nav/bluetooth/radio/phone systems that at this point I can't really see the wood for the trees 🤣 so any guidance would be much appreciated.

Sorry for the long post, it's been a slow day at work!

 

Thanks all,

Tony

 

 

Just a quick update, I thought I'd see what happens with the antenna disconnected from the Bluetooth module, I got a new fault code; 9458451

So would this suggest that the code I allready get (9458449)

Is not the antenna as I thought it was?
