Default How do I get out of "limp mode?"

Before I changed multiple sensors for get the Check Engine Light off on my 2001 1.8T Beetle, the dealership said that my car have transitioned to "limp mode."

I have now changed the MAS, Fuel relay, ETC and thermostat. Unfortunately, it's still in limp mode.

Is there any way to reset the computer on my own?

Also, does anybody know of any "performance software" that would allow me to mod/reset my computer's settings instead of buying a stage one chip?

Check the bottom two links in my signature.

1 to find a code scanner so you can scan your own codes and see what is wrong. The other to find a mechanic to work on your car instead of overpaying at the stealership.

Thanks for the advice. I completely agree.

FYI...I only took it to the dealership for diagnostics. There were too many codes to interpret what was actually going on.

I changed all of the sensors and parts in my garage. (dealership quoted me $1200...I did it for about $300!)

Will a scanner get it out of "limp mode?"

If you want to mod settings, you'll need more than the scanner in FL-Bug's link. You'll want the full blown version of VCDS, also known as VAG-COM.
This is a good site for info and purchase: Ross-Tech: Home

You'll likely need to reset all the codes to get the car happy again, which you can do with a code scanner.

Sweet! Thanks for the link!

Soooo...if I reset the all of the codes with a scanner, my beetle won't be "limping" anymore?

Find a good lookin' gal to rub/blow on it for awhile...always gets me out of limp mode.

In all seriousness, the only way to get it out of limp mode is to actually fix the problem. If its still in limp mode, you haven't fixed the problem. If you have any boost related codes (underboost/overboost) then you have an issue going on with the turbo...more specifically what controls the turbo. N75, wastegate actuator, vacuum lines, etc.

I concur on the VCDS recommendation, lots of troubleshooting ability there, far more than a generic scanner.

DZLBUG has it right you still have a problem that is keeping it in limp-mode. If I stay in full throttle to long my programing calls for boost that the turbo can't give so I go to limp mode. To get out of limp mode I simply shut of the ignition and back on; limp mode gone until the ECU sees a problem again. If you are constantly in limp-mode than something is still wrong. Somebody in your area should have VAg-com and could give you a print-out. Ask on your local forums.

Limp mode is there for a reason and very good one too. It helps reducing damage to ur engine and destroying it ! making it simply "go away" is not the proper manner. Most probable cause of the limp mode is having a boost leak which can be in one of the pipes or ur diverter valve needs to be changed. having a boost/vacuum gauge is a must in any turbo application and Id recommend u install one if u have not already ! once installed u can notice the way ur gauge acts and u can pin point the problem better. In my case I was running on SOFT LIMP mode (from 15psi at start to only a very stable 5psi driving) so I took it to a mechanic and once 3 small tubes where changed problem was solved ! it took me a year to realize I was in limp mode until I got the gauge ... There was a site which was very nice and explained howto diagnose engine issues with boost guage ... i will try to find it 4 u
