Bit Cheeky

[toasty]

A bit cheeky I know, but I've got some fault codes in my ecu that my 'shareware' VAG com can't/won't decode.

I will buy the full priced version when I have some money again (expensive Xmas) but in the meantime could someone tell me the meaning of the following ECU DTCs:

16955 and 17545

I also had a 17547 (Long term fuel trim add. Fuel:Bank2 System too rich)


Not sure how long they'd been in there, I cleared them a week ago and they've not come back yet.

...just curious really.

BTW, VAG.COM is an excellent product, I just love the data logging capabilities.
(still can't get my 0-60 lower than 6.01 seconds though)

Hi Dan,

16955 is Cruise/Brake Switch (A) Circ Malfunction
17545 is Long Term Fuel Trim Add.Fuel,Bank1 System too Rich

My name is Ram® and I'm one of 3 authorised UK suppliers of Ross-Tech diagnostics.

Let me know if you need anything!

Ram,

can you just give me a bit of sales spiel regarding VAG COM...

why would I want to buy it for my RS6?.. and if I detect certain codes what can I do about them??

Cheers
Dave

I'm tight fisted as well so I'll email you a full list of all the codes in MS Word. I have your email address Dan - anyone else want the file?

It is unquestionable that technology makes cars better, but as cars become more sophisticated, those who work on them must grow in sophistication as well. Modern cars, with their many electronic systems, require “electronic wrenches” to be repaired and modified. Generally, these electronic wrenches have been the domain of dealers and well funded repair shops. Though many new car dealers are excellent, most enthusiasts of any marque have accumulated enough bad experiences to make even the thought of going to one something to be avoided. And yet, if a trouble light comes on, the enthusiast has to take his vehicle to a dealer and pay for the service department to plug it into a computer and give him an estimate, indicating which parts the mechanic thinks needs replacement. This is an incredibly frustrating experience for owners who are capable of using conventional wrenches. Quite a few of us even own a computer, and it would seem to be a major improvement if we could plug our computers into our cars and learn what the dealer’s mechanic learns when he plugs in his. This is especially true for owners of vehicles no longer covered under the original manufacturers warranty.

The standard tool in a Volkswagen dealer’s service department is the VAG-1551 or VAG-1552 diagnostic tool. It is the dealers’ “electronic wrench,” and Volkswagen sells the tool only to its dealers. There are two alternatives for the enthusiast, however. VWTool/VDSPRO was one, but it was an early solution, primitive in today’s computing environment. It has not been supported for some time, though an update is planned soon. The other alternative is the Ross-Tech VAG-COM, a more recent development by Uwe Ross, a very talented computer engineer. Basically, Uwe Ross monitored the signals between a VAG-1552 and a car, reverse engineered them, and wrote a program that allows a PC to do everything a VAG-1552 can do, and more.

VAG-COM uses Volkswagen's proprietary diagnostic protocol and will only work in VW/Audi vehicles. In addition to showing fault codes and monitoring operating parameters, VAG-COM allows an enthusiast to make “adjustments,” such as reprogramming the locks or the stereo, re-aligning the immobilizer after swapping ECU’s and resetting service reminder indicators. VAG-COM can read any trouble codes in the vehicle, enabling one to diagnose a problem with the ABS, airbags or automatic transmission, and it can communicate with pre-1996 (non-OBD-II-compliant) cars. An OBD-II scan tool can’t do any of these things, and it costs more than VAG-COM, too.

There are some things the VAG-COM can’t do, such as “roll back” an electronic odometer, or “flash” the chip in the ECU with a new engine management program. VAG-COM can do things the VAG-1552 cannot. At this time, the most interesting “extra” is data logging, though due to slowness of communication between the ECU and PC, the sample rate is extremely limited. It would be useful for recording temperatures during a lapping session, for example, but less useful for monitoring a drag race. One caveat emphasized by Uwe Ross is that VAG-COM is a tool, not an on-line service manual. To make full use of VAG-COM, you will need a service manual containing the VAG-1551 Scan-Tool procedures for your car such as the Bentley Publishing manuals.

Some of the best paybacks for the tool is resetting Service Indicators for vehicles out of warranty and checking your car for errors before it goes to the main dealer for a service and seeing if they attend to them before you get your car back!

Here's a page containing a comprehensive list of codes:

Thanks Ram but actually what I did was cut and paste all the codes from this site into MS Word and reformatted the whole lot so that it is easy to read but more importantly easy to search for codes. So you put in the code number, press search and hey presto.

[Ram]

Cheers Joshie, Can you attach it to a post and stick it as a new thread on the VAG-COM section?

Many thanks,

Ram®

No problem Ram

Dave,

Originally I bought VAG.COM to just make sure all was well with my car.

But now I am totally obsessed with the logging features, they are just awesome!!

Whilst they are limited in the freeware version, you can still log, loads of stuff such as road speed, engine speed, various temperatures, battery voltage etc.. while driving along, then 'analyse' them in the comfort of your own home.

I've managed to produce some wicked graphs of 0-60 and even 100 along with engine speed plotted in the background, so that you can see shift points etc....

When I pay the £99 for the real version, I'll be able to measure boost presure aswell (and loads of other stuff)

Seriously mate, get it, it's just so much fun!

I am interested in a copy of the DTC codes. My e-mail address is charliea_62@hotmail.com.

Thx
