How do i reset my check engine light on a 2003 passat

SOURCE: Tank Flap - Electric : Will not open

I have a 2003 passat with the same problem, i noticed that the little nipple on the left hand side that releases to open the flap was inside the hole its self .

The book tells you nothing regarding this and i couldnt find on the internet how to get to it other than taking off the guard above the wheel and getting it that way.

I went out today and took the carpet away from the side of the boot closest to where the flap was.

I then saw the flap solenoid which had 2 little wires and a rod attached. The solenoid or motor as i call it was held on by two little bolts which i took off and had look at it but to be honest i had no idea what so ever as to what it should look like or do ha ha.

The rod that is attcahed to solenoid is the rod that comes through the hole to keep flap closed or to release it. I pushed the rod and couldnt see hyow it would release and hold so i took the rod off the motor and pushed the end of the motor that the hook was attached to and it made a noise i hadnt heard before but it was one of those good noises lol i didnt have any wd40 to spray on it as i used this for something else so i used some vaseline to rub on the end where the hooked rod goes onto and put the rod back on.

I then put the bit that comes through to lock or release into position and then bolted solenoid back in place and connected the wire again went to check thinking i am not that lucky and hey presto all mine needed was bit of lube lol and without the dirt and hassle of taking of the guard above the wheel.

Hope this helps as there is no way of opening this manually as i was told this monday when i called vw.

8.5 hrs + parts sounds about right. But why would a 7 year old cars oil pump fail? They usually last a lifetime. Has there been a lubrication problem? Low oil, cheap oil, wrong oil? But then again my daughters 04 Toyota needed a valve job, head gasket and water pump recently. I'm doing 90% of work and it still cost about $2000. Her problem was bad oil!

Purge Valve Removal & Installation, 1.8 L engine

1. Disconnect the electrical connector.
2. Loosen and remove the hose clamps and remove the valve from the EVAP hoses and remove the valve.
3. Installation is in reverse order of removal.

This code indicates that you have a faulty secondary air injection system. Basically this is a system in which pumped air is allowed into the exhaust system to help burn off any residual fuel droplets when the engine is warming up and thereby reduce hydrocarbon emissions. The 'injection of air' (opening of the valve) is by vacuum supplied by a thermally resistant over-braided vacuum line. Find your combi 'air injection' valve on the exhaust manifold and then check the integrity of the length of over-braided vacuum line. There is a good chance that the fault is merely a leak in this line (a poor end fitting) and this in turn is failing to supply the necessary vacuum to open the valve to allow pumped air into the exhaust. Hope this helps point you in the right direction.

How to check & change oil in automatic transmission on a 2003 VW Passat

At the bottom of the automatic gearbox (tiptronic) you will find 2 threaded plugs on below surface. First (in front of the car) is for emptying, and second is for filling up. Tightening torque is 24 Nm.



Automatic Transmission Fluid (ATF) checking:
1. Requirements for check:
1.1. Vehicle standing on level surface.
1.2. Transmission must not be in fail-safe mode.
1.3. Shift lever in "P" position, parking brake applied.
1.4. Engine idling.
1.5. Air Conditioner and heater OFF.
1.6. ATF temperature must not exceed 104 Fahrenheit degree (40 Celsius degree) at start of test.
1.7. Only ATF with designation ESSO LT 71 141 may be used. Do not use any lubricant additives.
1.8. Automatic Transmission Fluid ATF - part number: G 052 162 A2 (1 liter wrapping)
1.9. An ATF level check when transmission oil temperature is too low results in overfilling, when too high results in underfilling.
2. CAUTION: Too much or too little ATF will affect the operation of the transmission. The ATF level must be checked at regular intervals.
3. The oil level is correct if a slight amount of oil runs out when ATF temperature is between 86 Fahrenheit degree (30 Celsius degree) and 113 F deg (45 C deg) (caused by increase of oil level when heated). For warmer climates, 122 F deg (50 C deg).
4. Hang filled ATF reservoir VAG 1924 as high as possible.
5. Shift lever in "P" position, engine running at idle.
6. Place oil drip pan under transmission oil pan.
7. Remove ATF filler plug (at the bottom of the automatic gearbox you will find 2 threaded plugs on below surface. First (in front of the car) is for emptying, and second is for filling up.
8. With ATF temperature between 86 Fahrenheit degree (30 Celsius degree) and 113 F deg (45 C deg), for warmer climates, 122 F deg (50 C deg), a slight amount of oil will flow from filler hole when ATF level is correct.
9. If necessary drain or top off ATF to attain correct oil level. Top ATF with filler hook from VAG 1924 ATF reservoir. Insert VAG 1924 (tool) ATF reservoir filler hook into filler hole and top off until a slight amount of oil flows from filler hole.
NOTE: Fit filler hook into one of the oil deflector cap slots placed on the filler opening.
CAUTION: Do not press filler hook upward or oil deflector cap can be pushed off.
10. Reinstall ATF filler plug. Tightening torque is 24 Nm.
