On the 1993-1999 Volkswagen Jetta, the single ignition coil/coil pack on the 8-valve 2.0L ABA and the coil on the 2.8L VR6 is a well-known failure point. The plastic coil housing cracks and degrades under underhood heat and vibration, allowing spark to jump to ground or another plug wire, causing misfires on one or more cylinders. It is one of the most frequently reported driveability faults on MK3 Jettas and is documented generically by RepairPal for the Jetta ignition system. Aftermarket coils are notoriously unreliable on these cars; owners consistently report the misfire only clears with a genuine OEM VW coil. Left uncorrected, sustained misfire can overheat and destroy the catalytic converter.
Replace the ignition coil pack with a genuine OEM VW unit (aftermarket coils frequently fail again quickly). Replace the ignition wires and spark plugs at the same time, and inspect the coil connector and power/ground for corrosion. On the 2.0 ABA also check the ignition control module/power output stage, which can take out coils repeatedly if faulty.

On the 1993-1999 Volkswagen Jetta, early MK3 Jettas were fitted with an engine coolant temperature (ECT) sensor with a black or blue top that is prone to internal failure. When it sends bad data, the ECU miscalculates fuel and timing, and the dash temperature gauge reads erratically or the cooling fans fail to switch on/off correctly. Volkswagen released an updated, more-reliable green-top sensor (part 059 919 501A), which became the de facto fix carried across MK3/MK4. It was never a formal recall but is one of the most widely recognized VW fixes of the era. Any MK3 still wearing the original blue/black sensor is a strong preventative-replacement candidate.
Replace with the updated green-top ECT sensor (VW 059 919 501A) and a new retaining clip and O-ring; the part is inexpensive and the job takes minutes. Top off/bleed coolant afterward. Inspect the connector for melted pins or corrosion.
On the 1993-1999 Volkswagen Jetta, the power window regulators on MK3 Jettas are a classic, high-frequency failure. The plastic cable-drive regulator uses a nylon cable/slider system that wears, frays, or seizes, and the window drops into the door or jams part way. It commonly strikes the front doors first. This is one of the most-discussed complaints across VW Vortex, VWForum and RepairPal for the platform. It is an age/wear item rather than a safety defect, but nearly every surviving MK3 will need at least one regulator.
Common Symptoms
Window stuck up or down
Window falls into door
Grinding, chattering or clicking from door
Window moves crooked or off its track
Slow or unresponsive window
How to Fix
Remove the door panel and replace the failed window regulator (front regulators are the most common). Reinforced aftermarket regulators are available and are often more durable than the original VW part. Inspect and re-grease the window channels/felt runs to reduce load on the new regulator; test the window switch and motor before reassembly.

The Gates Corporation (Gates) is recalling certain aftermarket Tru-Flow Water Pumps, part number TFW 41127, sold at certain NAPA Auto Parts and/or installed by automotive service technicians after November 1, 2013 (and manufactured August 2013 through October 2013) that have a black-colored pulley/sprocket or do not have 'US9377' stamped on the water pump housing. These service replacement parts were sold for use in model year 1999-2005 Audi A4, 2000-2006 Audi TT, 1998-2005 Volkswagen Beetle, 1999-2006 Golf, 1999-2008 and 2011-2013 Volkswagen Jetta, and 2000-2005 Volkswagen Passat. In the affected water pumps, the pulley or sprocket that turns the timing belt may develop microfractures causing the timing belt to fail.
