The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems ca cause many drive-ability related problem such as rough idle and other symptoms

SOURCE: horn,airbag light,cruise control

ON CERTAIN MINIVANS, THE DRIVER'S AIR BAG MAY BECOME DISABLED DUE TO A FAILURE OF THE CLOCKSPRING, WHICH IS LOCATED IN THE HUB OF THE STEERING WHEEL. Consequence Summary: THIS CONDITION WILL MANIFEST ITSELF THROUGH ILLUMINATION OF THE AIR BAG WARNING LAMP, AND COULD EVENTUALLY RESULT IN A DRIVER'S AIR BAG OPEN CIRCUIT, IF THE PART IS NOT REPLACED IN A REASONABLE AMOUNT OF TIME. Corrective Summary: DEALERS WILL REPLACE THE CLOCKSPRING ASSEMBLY ON ALL COVERED VEHICLES WITH 70,000 MILES OR LESS. FOR THOSE VEHICLES WITH MORE THAN 70,000 MILES, DAIMLERCHRYSLER WILL OFFER AN EXTENDED LIFETIME WARRANTY UNDER WHICH IT WILL REPLACE THE CLOCKSPRING AT NO CHARGE IF IT FAILS. DAIMLERCHRYSLER WILL ALSO REIMBURSE OWNERS WHO HAVE PAID TO HAVE THE CLOCKSPRING REPLACED ON THEIR VEHICLES. THE RECALL BEGAN ON OCTOBER 12, 2004. OWNERS SHOULD CONTACT DAIMLERCHRYSLER AT 1-800-853-1403. A malfunctioning clockspring can also effect your cruise control,radio, wipers, and your horn relay. This can also happen one at a time til none of these are working.The solotion is to get the clockspring replaced . I DO NOT suggest you doing this on your own!

SOURCE: transmission fluid level check 02 jetta tdi auto

VW didn't put a "dipstick" on the trans for whatever reason. You technically have to use the VW Vag-Com scanner to properly check the trans fluid level as VW says it has to be checked at a specific temperature. But there is a "shade-tree" workaround. Start the car and leave the engine running the throughout the entire procedure. You have to get the trans fluid warm-a little under normal operating temp. 95F-104F is what you want-you can attain this after letting the car idle for 8 or so minutes. Continuing, leave the trans in park, and make sure you are on as level of a surface as possible. Then loosen the allen plug on the bottom of the trans pan. You will then see another plug. Remove this plug. Fluid should just trickle out of the hole if it is at the proper level. If it trickles out, you are good. If it doesn't you need to add fluid. Add VW spec ATF through the fill port.The fill port on the top front of the trans is capped off by a red cap and is very visible. Very carefully pry the cap off and then wiggle the plug out. I'd highly suggest having a spare red cap on hand-VW dealer has them. Then you can pour fluid into the trans. Add a little bit at at time, and all the while watching for the fluid to tricke out of the trans plug hole. When it trickles out, replace the inner plug and then the outer plug. That's it. Recheck after driving the car for a few miles. FYI- A flud and filter swap on the the VW auto trans takes 3 liters, so keep that in perspective. I hope this helps you out.

SOURCE: transmission won't go into overdrive when engine is hot

Lexus's have a complicated system of electronics that control the function of the transmission.Under normal operating conditions the transmission is controlled by the ecu and by a secondary system called a drivetrain control module. usually when a fault occurs it sends a code to the ecu and the check engine light comes on.
If this light does not come on then typically the electronic modulator is at fault and needs to be replaced.
If the check engine light comes on when the vehicle is hot i need this code to guide u further for the repair.
If u want to attempt the repair , be wary. its messy and takes time to do to do it right.

My engine light is on, my speedometer sometimes works and sometimes doesn't register, some times it bounces back and forth.


code p 500 refers to vehicle speed sensor (VSS) --circuit malfunction====causes ---wiring---VSS sensor---ECM
the engine light reports serious faults with both the engine and the transmission
I would go to an accredited auto transmission shop and have the VSS replaced or checked
The VSS drives the speedo, cruise control,gear changes ( reports to the transmission control module (TCM)

Could be a Vehicle Speed Sensor (VSS) Located on the transmission. Not an expensive fix at all. Have a diagnostic check run on it from any auto parts store if you have a check engine light on.

Either a blown fuse or the Vehicle Speed Sensor. Check fuse #7 & #13 first. The VSS is located on top of the transmission up near the firewall.

Speedometer quit working


There is no Speedometer cable on a 2002 Jetta. You have a VSS (vehicle speed sensor) I would have someone check the codes on it and see if the VSS is the problem.

Speedometer and odometer stoped working


this is a tough repair since the VSS, vehcile speed sensor is usually corroded to the transmission. It is on the top rear of trans, has one 10mm bolt and a 2 wire connector. The plastic gear on the end of the VSS wears out. Or the signal stops.

The cruise control quits too.
