I have a 1999 VW golf 2.0 gl code P0322, P0422, and P0303 code. I need help

2.0L liter? must be MARK IV in UK???? petrol right? not 2.0 TDI

ours is USA only 1.8L I4, here. +2.5 and 2.8
or 1.8L is belted cams.

In UK the belt is 120km /5year rated. at VW


the manual said for p0322 , the 2 sensors read wrong
that means it is out of time.
and fully normal this old. ignored for 20years, 2002 to 2023?


if the cam belt is bad
1000 new cam and crank sensors will never ever fix the car.
see?
with a water pump too see how it runs off the same cam belt>
do the full kit.

see this for fast example, and real, belt, I'd buy gates belts.or DAyco.

Watch the video at the link. The instructions are after the intro video. Cabin Filter Replacement Volkswagen Golf 1999 2006 2001 Volkswagen Golf GL...

P0322 means problem with CKP/crankshaft position sensor/.If your VW running well just ignore the trouble code otherwise the sensor need to be replaced

The sensors are usually found on the oil filter flange housing with the oil cooler. Also there are two dynamic sensors to measure pressure below 2000 rpm and above 2000 rpm so it could warn you of pressure loss within those two ranges.

replace plugs and wires.if it still misfires.you have a bad coil.and the fuel injectors 3 and 4 could be dirty and stopped up.

It sounds like the hydraulic lifters are bleeding down after sitting for a while... there are ball checks which are supposed to prevent this... Try using a good engine flush (a product that frees sticky lifters) and replace the oil with a good synthetic... Hope this helps...;-)

P0422 does not refer directly to an O2 sensor. That is a different code. P0422 is about the CAT. How many miles you have it and when did you buy it? VW has extended a warranty on the New Beetles for the CAT to 120,000 mi and 10 yrs. I had the same code and took it to the dealer to see if they'd replace the CAT in the warranty and they did. I had 47,000 miles and bought it at the end of Aug 1999, so I just slipped through. They replaced the downstream O2 sensor as well - all free of charge!

Hi,
A good start would be to go you the Diagnostic Trouble Codes list at http://www.bentleypublishers.com/tech/vw/vw.dtc.table.htm

The DTC's, also known as fault codes, may have other meanings but the list above should point you in the right direction.

Hope this helps - if so a rating would be really appreciated. If is doesn't then "add a comment" instead and I will try to help you further.
Cheers D..

sometimes it can be found on the radio casing but the best bet is to take your car to your local dealership and they can use the VIN nimber of the vehicle to track down the radio code

remove radio and fit a decent one. use the money vw would charge to recode it to buy a cd player with warranty. buy/borrow the two keys to remove the gamma
