I am new to the TDIclub and would like to know if anyone has compiled a list of frequenlty used abbreviations and there meanings. Some of the post that might have useful information, are useless secondary to the use of abbreviations I have no understanding of. If there is a list out there please let me know. Having a cummins turbo diesel, I belong to the TDR (Turbo diesel Register)---they have in their (FAQ-Frequently asked questions) a list of abbreviations and there meanings. This has greatly helped me as well as others and would like to see one compiled here. THANKS----New Member

I just did a search and... Most of the 'hits' are a bunch of fooling around. Here's one link that tells a few, not many...

http://forums.tdiclub.com/showflat.php?C...part=1&vc=1

A complete list may be a bit hard to find. After a bit of reading, many will come to light... Do a search and try 'acronyms' not abbreviations...

A few to start:

ABS= Antilock Brake System
ASR= Anti/Acceleration Slip Regulation
CAI= Cold Air Intake
CEL= Check Engine Light (same as MIL)
ECM= Electronic Control Module (Computer)
ECT= Engine Coolant Temperature
EGR= Exhaust Gas Recirculation (a valve/system on the car)
EGT= Exhaust Gas Temperature
FI= Forced Induction
GP= Glow Plug
IAT= Intake Air Temperature
IC= InterCooler
IDI= Indirect Injection
IQ= Injection Quantity
MAF- Mass Air Flow Sensor
MAP= Manifold Absolute Pressure
MFA= Multi-Funktions-Anzeige -or- Multi Function Display
MIL= Malfunction Indicator Light/Lamp (same as CEL)
MY= Model Year
NA= Naturally Aspirated -or- North America(n) -or- Not Applicable
PD= Pump Duese (injection system) (edited)
PPM= Parts per million
SOI/COI= Start/Commencment of Injection
TB= Timing Belt -or- Tuning Box
TDI= Turbocharged Direct Injection
TPS= Throttle Position Sensor
VAG= Volkswagen Aktiengesellschaft (Volkswagen Corporation)
VAG-COM= Software and cable combo to read and adjust the cars computer
------------------------------------------------------------------------
AFAIK= As far as I know
FYI= For Your Information
IIRC= If I remember correctly
IMO= In my opinion
IMHO= In my honest opinion
ROFL= Rolling on floor laughing
ROFLMAO= Same as above but different
TTT= To the top

Well, that should get you started...

FlyGuy;
That is a nice list. I have been around this and other forums awhile, but am not always 100% of the meanings of acronyms that are being used. I even found a couple I could use.

I think the FNG (same as New Guy, only different) has a valid point. Maybe there should be a list of commonly used acronyms in the FAQ.

Just my $.02 worth.

CF,CG,CH,CI-4 – API oil standards for compression ignition (diesel) engine


[/ QUOTE ]

Not exactly correct. The recent API oil ratings for diesel engine motor oil are CF, CF-4, CG-4, CH-4, CI-4. All of these can substitute for CE, CD, CC, CB, and CA. The -4 ratings can substitute for earlier -4 ratings (e.g. CI-4 can substitute for CH-4, CG-4, and CF-4). However, CF and CF-4 are different and cannot be substituted for each other. Which means that an oil rated API CF is not suitable for recent TDI engines that accept API CF-4, unless the oil has some other rating (e.g. API CF-4, CG-4, CH-4, or CI-4, or the appropriate ACEA or VW rating) that is acceptable.

Diesel engine motor oil ratings from ACEA:

B1, B3, B4, B5. Note that they are not necessarily substitutes for each other; recent non-PD VW TDI engines accept B3 or B4, but not B1 or B5. The A1, A2, A3, A4, and A5 ratings are ACEA ratings for gasoline engine motor oil.

VW oil ratings:

505.00: for many non PD TDI engines such as those sold in the US through the 2003 model year.

505.01: for PD TDI engines like those sold in the US for the 2004 model year. Engines that specify this rating often don't accept any other oil rating (although the oils that have this rating may have some other oil ratings).

500.00, 502.00: for VW gasoline engines.

Isn't it "Dual Sequential Gearbox" ?

I think you're both half-right: Direct Sequential Gearbox.

OTOH, maybe it's some abbreviation in German, sort of like MFA...

I checked into this one carefully before posting it. More technical minds can describe what differences there may be between direct selection and dual sequential.

However, if you punch the terms into Google, with "vw", you'll get many more hits, and more authoritative ones, with "Direct Selection Gearbox."

For instance, a press release from Volkswagen UK.

Update: It now appears that the proper phrase is Direct Shift Gearbox. Thanks to ufoguy, who pointed this out based on his drivers manual insert.

2TF = 20 Year old Tractor Fuel


this simple and innocent sounding abbreviation is directly repsonsible for putting Fred's on the map and making it a world-renowned stopover for people wanting to discuss TDis.

Here is the famous quote from Ric Woodruff that made history:



[ QUOTE ]
Ric Woodruf says:


Today, I dumped into my Ford Tractor's fuel tank the last couple gallons of that ancient diesel fuel that I put into my TDI about 6 months ago (you know, the fuel that smells like paint thinner).


Shortly after starting, the engine quit. A white mist came out of the exhaust pipe during subsequent cranking to try to restart. Oh, no - water in fuel!!!



I yanked the fuel line off of the injector pump and let it drain for a while onto the ground. A bunch of crud was visible going into the fuel filter.



I reconnected the fuel line to the injector pump and cranked it. After about 10 seconds it started running, and after about another few seconds it ran like normal. Water must have been at the bottom of the tank.



The most curious thing about the old fuel is that it seems to run cleaner than ordinary (fresh) fuel. There is no detectable smoke, whereas normally exhaust is quite apparent, both visible and especially the smell.


I will be changing my fuel filter soon.

As a new member and eye-strained reader, I found it challenging to try and guess what each of the many three letter acronyms meant.

The Amsoil thread is a treasure trove of incomprehensible abbreviations to the neophyte. I figured out a few, made a few wrong guesses confirmed here (awesome list) and perhaps it's only used in the Amsoil thread, but this one had me pondering for a while:
