Using Vagcom On A Mark 2 2.8v6 (2002) Auto

[Paul B]

Hi all,

 

Recently went on holiday (1500 miles) during which the Engine Management Light came on. Called out AA, who checked the fault code and found it was P1152 (MAF related). He reset the light, and it disappeared for several miles, before re-appearing. The car runs fine, with no loss of power or mpg. I have fiddled about with the MAF since returning home, and now want to reset the Engine Management light, to see if I've cured it or not. So I have purchased an ODB2 lead (usb variety), and downloaded VAG 409.1 from Ross-Tech. The lead seems to connect through to the car, but it questions which vehicle I'm searching (which chassis). I have selected VW Sharan, and Seat Alhambra, but it just continously searches eventually finding nothing. On connection, the computer says it's connected ok (through COM2) which I've tested and saved, but I am unable to get any further.

 

Which selection do I need to make from the Chassis Menu? Surely it should be either Sharan or Alhambra? Any ideas? Any help would be appreciated. I am running XP on my Acer Laptop.

Many thanks.

Hi PB

 

First you did not say where you got the lead from, but unless you got it from ross-tech it wont work, also the latest version of software is 704, but you say you have a usb lead, but is configured on

Com 2

 

so that is poss why it does not work.

Hi Radiotwo.

 

I bought the lead on E*&y, and it came supplied with the driver. I had tried to purchase from Ross Tech, but couldn't find the lead, let alone the price on their website! I had read that others had bought similiar to me, and that theirs worked fine. I have followed the instructions that came with it, ie making sure the USB serial port is set to Com 1, 2, 3 or 4. (2 in my case). It connects through and says the interface is ok, port connected ok. I'm not convinced v704 works, as it does even less with this loaded onto my pc! It just rejects it all completely. I have only seen mention of 409 on here, I've been reading about this on here for weeks! Thought it would be easy, but i'm sure i'm missing something simple.

 

Any help/ideas appreciated.

 

Many thanks.

how did you manage to get it to work in the end?

[big_kev]

My money would be on the serial port being 5 or above.....certainly won't be 2 !

How can it be 5 and not 2 ! he has a USB !!

Exactly ..... :16:

[Paul B]

Hi, don't fight folks!! Calm down! LOL

 

I checked that the USB port was set to COM2, as suggested by the instructions (not 5??), and downloaded an XP driver from a link in another thread on here. Went out to car, and it worked straight away. Even picked up on a fault code I didn't know I had! Now all I need to do, is see whether my MAF fault re-occurs to see if I've cured it! :16:

 

Thanks anyway folks. A problem shared..... and all that....

You don't seem to be picking up on the point! A Com port is a serial port and USB is not serial.

 

So you cannot set it to a com port if it is a USB !!

 

so please tell me how many pins the plug has? 9 or 25 ??

The lead he is using contains a USB to Serial adapter.

 

It will appear to Windows ( and hence to VAG COM ) as a "Serial port".

 

If using VAG Com 409 or above he will have to tick one of the "Serial Ports" ( 1 to 4 ).

Usually when installing a USB to Serial adaptor it will allocate port 5 or above ( although it can be changed to a lower number)

Vag Com will not recognise his lead as a USB port it will see it as a "Serial port."

 

Note: "Serial port" above refers to legacy RS232 type connections.....although USB is also a Serial connection.

 

Hope this helps.

Hi. Thanks Kev, well explained. I know the difference between a 9/25 pin serial port and a usb! But your explanation should be simple for all to understand!

 

Thanks.
