White smoke Audi 2.0 non turbo is this connected to excessive oil consumption is a 60k mile engine A4 reg 2001.

2 questions.
1) Is the oil actually low on the dipstick?
If it is, you might have an oil leak, so you would need to look underneath and see. Also look for puddles when you park.
The most common reason for such consumption would be a burst oil pressure switch, or a leaking valve cover gasket.
Either of these will leak lots of oil.
The last possible reasons, which are really rare, would be engine parts defective,( like oil rings), or a leak in the brake booster which would suck oil from the crankcase into the brake booster.
2) If the oil is not leaking out, and the dipstick shows full, you will be needing a new oil pressure switch, or to have the electronics repaired.
God bless your efforts.

definitely an oil consumption problem. How many miles? Could be worn rings and or valve guides. The oil light on when hot indicates low level or possible or weak oil pump. Check compression for possible head gasket or cracked head. I wouldn't drive it untill diagnosed.

• The 1.8L non turbo engine requires 3.4 quarts of 5 W 40 full synthetic (according to manufacturer specs) Always makes sure to start the vehicle after the oil change for a few seconds and shut it off, wipe the dipstick once and re-check the oil level it to make sure.
• Hope this helps and thank you for using FixYa.

General rules of thumb: Low speed engine on acceleration with smoke in the exhaust plume = worn piston rings High speed engine accelerating (spooled up turbo) with smoke = oil form turbo bearing and/or piston rings Engine on over run (coasting down, foot off the gas) with smoke = oil from valve guides. VW/Audi make good engines with tight tolerances so none of the above should apply at 62K miles; just make sure that the oil (the right oil) and oil filter are changed regularly.

This depends on the settings for the on board computer and the type of oil used for services.if set when NEW,using fully synthetic oil the service interval will show up on the dash as "service"(approx 20k/2 years) BUT if OEL shows,then use semi synthetic oil and change at 10k/every year.weight of oil should be 10/30 upto 60k then use 10/40 after or when you notice an increase of oil consumption.These engines WILL use oil, as the bores are plasma coated,roughly 1ltr to 500km is acceptable(according to AUDI).Yes i know that AUDI fit 5/30 when new from the factory,BUT only supply 10/30 or 10/40 to the dealers for aftermarket services....(they have a deal with castrol,gemini,worldwide).Same goes for all VW group products,after all it is a VW engine.

White smoke is caused by engine oil being burnt. If your vehicle is turbo charged then it is most likely the turbo bushes that are worn, allowing oil to escape into the exhaust system. This can also be caused by worn piston rings but is unlikely on a vehicle of this age unless it has overheated badly in the past. To check turbo, remove main intake pipe from turbo. Check for excessive movement on impeller shaft in turbo by moving it up and down. To check piston rings carry out a compression test or if you have the equipment a cylinder leakage test will give you a better indication of cylinder condition. If the Turbo is at fault it will need to be reconditioned or replaced. Check oil feed pipe to turbo for blockage or restriction [common fault].

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: 2003 Make: Audi Model: A4 Quattro Engine Type: 4cyl. 1.8Liter Turbocharged
Mobil 1 0W-40
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

Engine also smokes when car driving if turbocharger still faulty. Did you change the engine timing belt (the timing belt kit) meantime? What about engine oil consumption? When engine glow plugs (one or more) burnt then engine exhausts white smoke at idling. Also white smoke at engine idling when water is still present in diesel fuel.

How many miles/km's you drive in those 3 month's ? oil consumption is normal ! Check when you first start the engine in the morning wetter or not you see a puff of blue smoke, if you see smoke , your valve seals are leaking.
1 liter oil each 2000km is normal.

Most likely the turbo is gone. What ever part of the turbo went, just replace the entire turbo. Not serviceable 99% of the time. The engine will not like being driven for any extended period of time with a bad turbo.
