On the 1996-1997 Audi A4, nHTSA 06V403/Audi JS covers certain 1996-1997 A4 vehicles and superseded recall 00V317. The ignition-switch spring anchor can fracture so the key does not fully return to the run position after starting; windshield wipers and headlights may then be inoperative. VIN verification is required.

Common Symptoms

  • Key may not return fully to the run position after starting
  • Windshield wipers may be inoperative
  • Headlights may be inoperative

How to Fix

Check the full VIN in NHTSA and Audi recall systems. If 06V403/JS is open, arrange the free dealer replacement with the optimized ignition switch. If the key does not return normally or wipers/headlights are unavailable, avoid driving in conditions requiring those systems and obtain prompt service. Do not buy or install a switch from this recall card.

On the 1996-2001 Audi A4, One of the most common suspension issues seen on Audi A4s is worn or failed control arm bushings; the bushings receive the most pressure during braking or heavy acceleration, and these forces cause the rubber to fatigue and crack . When inspecting at the inboard end where the control arm mounts to the chassis, you may see cracks, leaks or missing pieces of rubber, and at low speeds hear a clunking or creaking noise when traveling over a speed bump . On the B5 A4, both upper and lower control arms wear — owners commonly report needing one upper on one side and a lower on the other .

Common Symptoms

  • clunking or creaking over bumps and speed humps
  • metallic squeaking from front end
  • vague or wandering steering
  • uneven inside-edge tire wear
  • vibration through steering wheel

How to Fix

Raise the car using a jack, find the suspected control arm, move it manually to check for looseness, and have a friend bounce the car so you can listen for noises . Most B5 owners replace the full set of 8 front control arms ('boomerang' kit) at the same time since labor overlaps. Replacing the control arms can be done for around $200-250 in parts if you do the work yourself ; a shop replacement typically runs $800–$1,400 for the full front-end refresh. Use OEM-quality brands (Lemförder, Meyle HD, TRW) — cheap eBay arms commonly fail within 20-30k miles.

Typical repair cost:$250 - $1,400

On the 1996-2001 Audi A4, the original black-housing dual coolant temperature sensor (G62) mounted in the coolant flange at the back of the cylinder head develops cracks and fails internally. The temperature sensor G2 (also known as G62) for the gauge has likely failed and is relatively easy to fix; it is located in the coolant flange at the back of the cylinder head and the early square-connector style and later elongated D-shaped black connector sensors are known problematic units. When it fails the ECU sees an implausible coolant temperature, leading to cold starting difficulties at low temperatures, poor idle and acceleration during warm up as well as an erratic or dead temperature gauge.

This issue also affects: Volkswagen New Beetle, Volkswagen Passat, Audi A1

Common Symptoms

  • erratic or dead coolant temperature gauge
  • hard cold starts
  • rough idle during warm-up
  • poor fuel economy
  • rich-running condition
  • check engine light

How to Fix

Scan with VAG-COM/VCDS for fault 17664 / 16502 (P0118) and bench-test the sensor's resistance. From Bentley, the G62 test procedure: allow engine to cool to room temp (68F/20C), disconnect ECT sensor, connect multimeter to terminals 1 and 2; resistance must be 1500 to 3000 ohms — if not, replace the ECT. Replace with the updated green-top OEM sensor (part 059 919 501A) along with the retaining clip (032 121 142) and O-ring; replacing this sensor resolves running issues for many owners who are still using the original black sensor which had a high failure rate. Part is ~$25-40, DIY 30 minutes; shop labor brings total to ~$80-180.

On the 1996-2001 Audi A4, the large red multi-function display in the center of the B5 instrument cluster (Jaeger/VDO speedometers) and the smaller climate control LCD both lose pixel rows and segments as the silver-conductive ribbon-to-LCD bond degrades with heat cycles. The common thing is the big red fading LCD in the middle, with missing lines or columns and disappearing LCD pixels (sometimes getting worse when warmed up). Drivers see missing lines/columns in the odometer, trip computer, gear selector indicator, and HVAC temperature readout — often worse when the cabin is warm. The fault is cosmetic-to-nuisance grade but can hide important warnings (oil temp, mileage).

Common Symptoms

  • missing rows/columns on red MID display
  • blank or partial HVAC temperature digits
  • fading display when interior warms up
  • unreadable odometer/trip computer
  • intermittent display flicker

How to Fix

For the instrument cluster, replace the LCD ribbon cable or full LCD module (Minitools SEPDISP09, Module Master, or Pixelfix kits, ~$30-80) — requires removing the two torx screws holding the cluster, pulling it out of the dash, and disconnecting the three connectors on the back (push purple retaining clips upwards) , then disassembly and careful soldering of a ribbon connector. The SEPDISP09 consists of an LCD display with FPC to be soldered (using tin solder) to the main board of the dashboard, and a good level of skill and soldering experience are required. For the climate control LCD, a plug-and-play LCD kit (Module Master/Circuit Solutions ~$60) installs in roughly 30 minutes. Module Master will swap out the LCD for something like $150 and takes about a week , so send-in repair services run roughly $100-200 if you prefer not to DIY.

Typical repair cost:$60 - $300
