vagcom installation

[andyg plym]

So I thought id have a go at buying a cheap (£8 delivered) ebay vagcom lead with one of those mini discs.

I have heard a mixture of good and bad but thought it was worth a punt

It took a few minutes to install the program but then the fun started, my obd ports are dead and whenever I want to use them I have to hard wire a live feed from one of the fuses.

I had to search high and low on the net about how to get the car to hook up to the laptop, and it was to do with the "comm ports" so had to slightly reprogram the system but eventually got there.

It connected soon after, I saw the title come up of my current chips

Finally managed to search for fault codes and it said 305 were stored

I began to work my way down but then.....the program stalled and I haven't been able to get back on since.

I'm fairly sure I loaded the program twice in error, could this be the cause?

Thanks chaps

Is the cable a USB type?

[andyg plym]

Yup, typical blue one with a red led light on the end

When they have problems it's usually the driver for the com port part of the cable. Have a look in device manager and make sure it is showing as a com port and that vagcom is set to that com port number.

Are you connecting in the fuse box (left side in the photo below) with a 2 x 2 adapter cable?

Yes I think that's how I managed to eventually connect. I will try uninstalling the program the reinstall it

[andyg plym]

Yes dave of course !

[UrS4boy]

Yes dave of course !

Just checking.

So anyone beat 305 codes ? Surely that's not correct

[rj scotty]

Many of them will show as intermittent i.e. where there but gone now. Just powering up with things disconnected will log a load of fault codes.

That is the most I have ever seen though.

305 is totally impressive dude

If you've been connected but it won't connect now, try restarting the laptop with the cable already plugged in.

There is a fuse for the ODB port, I think it might be 14??

The cables like a low number for the port.

Do it with the engine running to avoid flattening the battery while you're mucking about


Take care how you connect the 2 x 2pin plugs, with the cheap ones they don't fit that well and it's quite easy to get them the wrong way round.

I did manage to clear them, tried saving but I don't think it saved. I wanted to study the codes but thought I'd reset and go for a drive. The car was started and noticeably different on tickover. Took for a blast and flew! Then went into limp mode, switch engine off and on again and it's fine.

Boost issue somewhere as should be 2bar but only getting 1.5. Some of you remember my other issue if when I rev it the rev counter flicking to zero as if the ecu resets well that's now gone rev limiter is 7.5k and doesn't cut

Looking forward to resetting it all up again for another go

[rj scotty]

glad your on your way to sorting it mate

It might have saved the codes in the Vagcom program directory on your C drive (C \ programs \ Vagcom \ logs? etc.

What I usually do is click on "Copy Codes" then paste them into a txt file on the desktop.
