P3081 DTC: Anyone help?

I have an 03 Jetta 1.8T, with a DTC of P3081. Nobody has this info handy, and the dealer simply tells me that it's a system fault (sounded like BS to me). Does anyone have the code definition for this? It appears to be VW specific. Any help is appreciated....

I don't believe this is a code...it's not published anywhere on the WWW. I haven't seen any DTC code list including it. If it is real then you're the first to experience it hehehe..how does that feel?
hhahaha

Kinda sucks....I went through all of my references, and found nothing, but it's real, as witnessed by my scanner. I've never seen a code starting with a 3....anyone?

Without going into a lot of detail, try replacing your coolant temp. sensor. It is a relatively cheap part at the VW dealer....should be under $10. Install the new sensor, then clear the code & report back.

Good luck! :)

Good Morning,

"19537 4C51 P3081 Engine temperature too low"

That DTC is indicative of a missing thermostat, a stuck open thermostat, or a cooling system with 100% antifreeze. It is NOT associated with a defective ECT G62.

Art,

You're the man! :) Great info. I hope it helps the original poster to solve their problem. I guess it goes to show that any advice that I give should always be taken with a grain of salt.;)

Art, I'm thankful you're not the type to flame me when I give well-intentioned, but incorrect advice. There are a few folks on these forums that respond to posts such as mine with much less class & tact.

Thanks you for the info guys! It's a great help. Coincidentally, where were you able to find this info? I tried everywhere, and nobody had it? Thanks again...

Good Evening,

Like they say in the movies, "I could tell you, but then I'd have to....", well you get the idea. Let me just say that I may have a bit more information in this particular area than you do.

Hi...I have a Jetta 2003 1.8T also. The malfunction indicatior lamp came on yesterday too. The autozone guy told me the code was P3081 also. Did you ever find out if it was the coolant sensor? What was the code mean? How much did it cost you?

Thanks,
Jenny

Good Morning,

When the coolant temperature is too low, that does not necessarily mean a sensor failure. Sounds like the sensor is telling you the truth.

Watch the temperature on the scan tool as the engine warms up. Look for things that keep it from warming up. Things like radiator fans on all the time, straight anti-freeze, stuck open thermostat and so on. That is what it means. It means a system problem, not necessarily a component failure.

I have a 2004 New Beetle CV with 2.0. Had the MIL come on and took it to AutoZone. They said it was code P3081 and also said it was indicating on their scanner "fuel air metering". I thought the codes would mean the same thing (coolant in this thread). Am I wrong. I haven't been able to find this code anywhere but here.

Thanks

Sorry, forgot to ask: My wife said she might not have got the gas cap on tight when she filled it up. I know this can cause the MIL light. Will it reset on its own, or does it have to be reset? And if it has to be reset, how do I do that? (Don't have a scanner)

Thanks

LOL..!

KevP, P3081 is what Art said it is for VW. Codes are not standard for all car, they don't always mean the same for all cars except the code that start with a POxx.

To reset the code, Autozone should be able to do it with their generic OBDII scanner, else go see a VW mechanic or buy a VW scanner....

Good luck.

Art-

Since you have been so helpful, I have an '03 GTI 1.8T, also with error code P3081. Same code, same engine... same problem?

Thanks

Good Evening, xen355

The DTC P3081 is the same for ALL VW and All Audi vehicles, but probably won't be the same for other makes since it is within a group of DTCs that is "manufacturer specified". Same troubleshooting as above.

I have a question for ya Art...let me give you a bit of background before I start the question though. I have an 04 VW GTI 1.8T automatic tranmission with 71k miles. I took the car to the dealership for an oil change etc, they told me that both of the fans are running on high only and I need to replace them. Well that was over a month ago and I haven't yet. My engine light just came on about a week ago, I had it diagnosed and I too got the P3081 code. I'm wondering, if the fans aren't working properly because of the thermostat problem. Any insight? And should I get these fans taken care of now, or wait until they fail completely? It may sound like a dumb question, but I'm serious. Thanks for all of your help...you're super knowledgable and I figured you'd be the one to help me solve my problems. =)

Good Evening, ChelleWithTheGTI,

You asked a bunch of questions, so let me tell you what I would do (or have done).

If we take it on faith that the coolant fans V7 & V35 do not run, I need to know if it is because the fans have failed or if it is because the operating circuit has malfunctioned.

Check fuses S164 & S180 (#3 & #8) on the holder on the battery FIRST.

Looking at wiring diagram #38/4 in the Jetta/Golf/GTI Service Manual (VG05), I see that if I unplug the FC Module J293 and apply battery voltage to the disconnected plug at T4a/2, both fans should run on low speed if the fans and wiring are OK. If not, inspect the wiring all the way back to the fans and apply voltage to the fan directly at the fans (T3a/2 and/or T3b/2). Since both fans run on high speed, we can safely say that the ground connection at position 12 is OK. If either or both fans do not run after this test, than I would suggest that the fans are defective. I don't have any recent shop experience to be able to say if this is a problem area, but I think it unlikely that both have failed at the same time. I think it much more likely that the FC Module is the problem. By the way, look closely for burned wiring and connectors at the fans.

With all that said, P3081 is not likely to be caused by coolant fan problems such as you've described. A stuck open thermostat, too high antifreeze concentration, or coolant fans stuck ON are much more likely causes. Also, I'm aware that some performance ECM chips upset and disturb this part of the diagnostics.

Keep us posted as you diagnose this problem, and be sure to update your profile to show a location.

Wow Art, thanks for all of the great info, I took my car to a mechanic and they fixed the code problem. I got a bit angry with them for charging me a hundred bucks to diagnose and clear the code, even though I had already done that at an autozone. The engine light is off, and I will have to wait until I get a day off or two to try all of the other things you recommeded reference the fans. I'll try and keep you posted though. Thanks a ton!!

Good Morning, ChelleWithTheGTI,

Thanks for updating the profile.

"I took my car to a mechanic and they fixed the code problem"
Your post leads to the inevitable question; what did they do to fix it?

"charging me a hundred bucks to diagnose and clear the code"
In my part of the world, considering the expense of the computers and equipment along with the cost of doing business, (sorry to say) that sounds about right.
