Engine is using 1/2 qt of oil every 800mi, 1.8T '04 Cabriolet


Your mechanic is spot on. The A4's are notorious for turbo overheating and failure. The oil burn is coming in the TURBO itself and then being distributed to 2.3.4 as a side effect. Your not noticing blue smoke because your catalytic converter is doing its job and the minor smoke being generated is being taken care of in the CAT. If you continue to drive as is you will run a certain risk of catalytic converter damage, cylinder damage from fouling (cylinder wash) build up, sludge, etc. If your mechanic has the knowledge on this specifc model there is a way to test the turbo output and turbo heat generation to absolutely confirm. One last thing. in ANY turbo car its imperative to run QUALITY oils not your local wal-mart brand or no name. Many people are not familiar with the demands on a TURBO engine and oil change facilities pull standard oil from 55 gallon drums via a pump.. so you arent feeding your car properly. The AVG (Audi/Volkswagen) company recommends FULL SYNTHETIC and either Castrol or Mobil 1. I have a Turbo Diesel and use Mobil1 as my choice. The recommended oil for your car via their web page is Current Vehicle: Year: spacer.gif 2003 Make: spacer.gif Audi Model: spacer.gif A4 Quattro Engine Type: spacer.gif 4cyl. 1.8Liter Turbocharged

A fully synthetic motor oil, Mobil 1 0W-40 with SuperSyn Technology exceeds industry standards and the major leading builder requirements, enabling the product to keep performing well after conventional oils cannot. Mobil 1 is recommended by leading car manufacturers as initial fill

THE OIL LIGHT KEEPS COMING ON AND WHEN I ADDED 1/2 QT NOW IT IS KNOCKING REALLY BAD AND SOUNDS LIKE THE ENGINE IS GOING TO BLOW UP


you have low oil pressure, so adding oil will not cure the light, if the engine is knocking u have damaged the engine bearings and it will need to be torn down and rebuilt.

What the coolant system capacity


1.9L engine should be 1-3/4 gallon total. 50/50 mix would be 7/8 gal. of antifreeze (full strength) + 7/8 gal. of water, or go premixed 50/50, = 1-3/4 gallons.

2003 Chevy Impala transmission


Did you have it serviced or rebuilt, If you had it rebuilt I would take it back to the trans shop for warranty repairs.
If they just changed the trans filter I don't think it would cause your problem.You just have bad luck with the slipping trans
