Rpmayne 0 Posted March 7, 2005 There seems to be alot of different types of cables compatible with the OBD2 connector and a laptop running the VAG-COM software from Ross Tech. They seem to range from a straight cable with minimal circuitry contained on the OBD2 connector for about £30.00, to ones with interface boxes going from £50.00ish upwards. Has anyone bought any of these cables? Any idea what the differences are? Was thinking of going for the cheapest but, by normal 'you get what you pay for', would like to know how they are selling them that cheap.. Any recommendations?

kebabman 0 Posted March 7, 2005 I've got this one, and (once I'd plugged it in properly :oops:) it has worked perfectly on my mid-94 VR. 8) http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... 19175&rd=1 Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted March 7, 2005 So long as the lead has an opto-isolator in it you should be OK, otherwise there is a chance your Laptop could send voltage spikes to the ECU and kill it. Ross Tech seem to be combating these clone leads by restricting their software more and more. IMO, you can't beat the fully paid up and registered real deal from Ross Tech.

Rpmayne 0 Posted March 7, 2005 Phil, that's more the price range I'm looking, what software are you using and does it work with a RS232-USB converter? My laptop doesn't support RS232. Quote Share this post Link to post Share on other sites
corradophil 3 Posted March 7, 2005 It works with Vag-com, and yes it works with an R232-USB2 convertor. Make sure the converter is USB 2, apparantly people have had problems with non USB 2.

corradovr6sc 0 Posted March 7, 2005 I'm using a usb - serial converter and it works fine. Check out skpang - sells all the converter cables etc. Quote Share this post Link to post Share on other sites
Rpmayne 0 Posted March 7, 2005 Thanks. Would like to go the skpang route for easiness but a little pricely, think I'll try the kit form from andywhittaker and the converter. Should have most of the components at work, so I recon £30 all in should cover it. Take it the free version of VagCom is pretty cut down compared to the registered copy. Like the look of those 1/4mile graphs you can plot, hoping the free one does that. :D Quote Share this post Link to post Share on other sites
GIXXERUK 0 Posted March 7, 2005 Rpmayne, post back which you get mate and if it works well, what car have you got ? (engine) :-) Quote Share this post Link to post Share on other sites
Rpmayne 0 Posted March 8, 2005 I've got a '94 VR6 and have just won the following on ebay. Worked out as £30 delivered which seems to be the cheapest and easiest option. Will let you know if it works next week when I should recieve it. http://cgi.ebay.com/ebaymotors/ws/eBayI ... cN__Stores Quote Share this post Link to post Share on other sites

Rpmayne 0 Posted April 29, 2005 I received the cable a long time ago and have only just given it a go. I've got a USB to RS-232 converter which the OBD2 cable connects to. Thing is the VAG-COM software I downloaded just says it can't find the RossTech interface when trying to connect to the car. Is this copyright protection because its trying to find the dongle? Thought there was a free cut down version anyone can use? Quote Share this post Link to post Share on other sites

Funkster 0 Posted April 29, 2005 I bought an alpha-bid lead just recently and it works just fine. You need version 311.2 of VAG-COM to make it work as the newer ones don't support generic leads. Yarr, -- Olly Quote Share this post Link to post Share on other sites
