Question about 2001 Volkswagen Beetle

1 Answer

Had broken oil dip stick tube and a code PO171. VW 2001 turbo.

Replaced the tube and the code went away for a few days, about 150 miles of driving. But the code came back and returns after every reset. What can I check next?

The po171 code means the system is running too lean.
Try cleaning the maf sensor (mass air flow) and see if that works.
It can be cleaned with intake cleaner or brake parts cleaner that"s in a spray can.
The maf sensor is located between the air filter and the throttle body in a big black hose and has a wire connection to it. Be very careful when you clean it.

Where does one investigate oil consumption in a 1.8 liter turbo engine in a 2001 vw golf using 1-quart every 50 to 100 miles driven, no tail pipe smoke and no leakes on drive way when parked overnight. I...

If you don't drive this little beast hard the oil could be migrating to the charge pipes and inter cooler.

Usually the turbo is likely culprit when oil consumption reaches those levels. Pull the spark plugs to see if the tips are loading up with carbon deposits.

You can pull the lower hose of the inter cooler...drivers side under the bumper....and see if oil pours out. If so the turbo is shot.

Another way oil is consumed is valve stem seals allowing oil down the intake valve guides. Cure is a set of valve stem seals.

It sounds to me that your 4th gear is just starting to slip. It will gradually get worse until you are forced to overhaul the transmission.

My recommendations:

Clear the codes and drive the vehicle while at the same time, putting some money away so you will have the funds for an overhaul. It may do like this for a few weeks or several months, but it is well on its way,,,

2003 Beetle turbo-13 trouble codes-PO300-multiple cyl misfire-PO171-system lean, bank one, PO301, PO303, PO302,PO 304-cyl one thru four misfire, P0012-intake cam position timing over-retarded-bank one,...

Low fuel pressure will cause many of those codes to set.

Should have around 3.5bar pressure at idle and full throttle.

Check to see if VW has a recall on the ignition coils. They are cheap to replace will need your VIN# when you call.

Alternator problems can also trip codes . Check for a/c ripple at BATT + on more the 0.05vac allowed.

Valve train noise common complaint. ...often due to lack of oil services and/or incorrect oil type.

All 1.8T engine will clatter on start up one time or another and is considered normal as long as it goes quiet after 2 to 5 seconds at idle.

You should have synthetic oil in the engine.

P0012 is often timing incorrect. ...check timing belt at tdc.

These engines need a timing belt every 50,000 miles not the 100,000 miles VW suggests. Belt failure is catastrophic.

Transmission codes often corrosion in loom connections under battery. These need checked and cleaned with a solution of STABILANT22A applied to the pins.

If a scanner is available clear the codes and drive for 40 miles or so and recheck for codes. Transmission codes are not always due to transmission faults. They need 200 miles to re adapt after batter replacement or power off.

ROSS TECH site has lots of info' and a scanner program for your lap top.
