VW golf- engine warning light on. Had 2 sensors replaced - crank shaft and timing. And after 15 miles warning light is on again. Timing belt is new. What could the issue be?

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.

P0016 refers to the Cam shaft sensor and crank sensor not in sync , the P0011 refers to Variable Valve timing and Variable Camshaft Timing , as the P0016 has shown i would expect that is the issue between these sensors and the PCM , dont waste your time and money on trying to get a cheap fix this is a know issue with VW and a VW dealer will have the appropriate equipment to readily rectify the issue, i think this link will show why is best to go to a VW dealer, but the choice is yours , incidently there is no need to check for electrical issue as is a component based issue so a waste of time and money if your mechanic does the se first tests
VOLKSWAGEN P0011 VVT PERFORMANCE

check that the cam shaft is turning ( broken timing belt/chain)
run fault codes to check for cam/crank position sensor
check immobiliser operation

This will require the removal of the timing belt and the pinning of the injector pump to maintain pump timing. This engine is an interference engine and valve damage will occur if not done correctly. As there is no belt replacement period specified for the belt but industry standard is 60.000 miles so with a leaking seal ( oil destroys rubber belts) it would be prudent to consider a new belt, adjustment pulley and crank shaft seal as well. Have the job done by an accredited shop conversant with your vehicle .

Have you ever replaced the timing belt?? If not the problem is likely to be a loose worn out timing belt. A floppy belt will play havoc with the sensor signals and trigger a check engine light and a camshaft sensor code.

What is needed Tools: 6mm and 8mm allen wrench socket, 5mm allen wrench. 8mm, 13mm, 19mm socket and ratchet. 10mm combination wrench. Long ratchet extensions (at least one 6in, more are helpful). 5inch Wheel puller (for main shaft pulley). (Some models may need a special spanner tool to adjust the timing belt tensioner) Parts: 2 gal of anti-freeze mixed with distilled water. All three V-belts. (Alt, A/C, P/S) $32.95 New water pump top. $91.91 New gasket for WP. $9.13 New timing belt. $26.13.


Procedure:

Remove battery cable (either power (+) or ground (-)) remove alternator remove A/C remove power steering pump .Remove water pump pulleys remove main shaft pulleys remove timing belt covers remove A/C mounting hardware remove timing belt (don't turn any of the wheels its connected to) replace timing belt adjust belt tension remove water pump face put on new gasket and new part.

Leave pulleys off. replace bottom timing belt cover, replace crank shaft pulley, replace steering pump, replace A/C, put small belt on A/C (hang loose) put large belt around A/C, Main and water pump pulley. put middle size belt on Main water pump and power steering pump reattach bolts for the steering pump pulleys put alternator back on adjust all belts. connect battery

Problem areas:
Main pulley: There are 4 6mm hex head bolts. These must be removed. The main 19mm hex head can be used to turn the engine it the timing belt slips and you have to readjust the timing.

Putting on new belts: This can be a real pain if you get VW belts. The adjustments won't give enough to put the belts over the edge so the easy way is to remove the pulley on the water pump. Then its real easy.

Timing: If you turn the wheels that the timing belt goes on you will have to reset the timing. Mark the timing points with something like whiteout so its easy to see. The timing mark on the toothed gears are small dots. The timing mark for the crankshaft is a small cut on the outer pulley. When its aligned with the intermediate wheel timing mark (there is an arrow on the cover as a hint) should intersect as viewed from the right wheel well. The camshaft timing mark should line up with the top of the engine near the front.

Power steering pump: It is held on with lots of bolts. One is in a channel that is hard to see but can be found with a 6" extension. If you look at the pump you will see three bolts that go into the housing. This should give you an idea where the forth is.

Changed the timing belt and knocked loose the wires or connections to the sensors on the mass airflow device.

1. remove air intake pipe, and box (upper and lower section)
2. take off timing belt cover
3. take off serpintine belt, and v belt
4. rotate engine to TDC marks line up on crank and cam. camshaft says O^T on it and on the cover behind gear, crank has a notch in the pulley and a arrow on the cover to line up
5. remove crank pulley 6mm allens not the 19mm 12 bolt
6. make sure timing belt is still at TDC remove lower timing belt cover there is 3 bolts and a nut holding it on the nut is by the water pump and the bolts are on on top and 2 behind the crank pulley
7. remove cover
8. mark intermediate shaft shaft right above the crank pulley
9. remove belt
10. install reverse of removal make sure to line up all 3 pulleys cam crank and intermediate shaft or it wont run and depending on how bad it is out of time if you do it wrong you could bend valves

Assuming this is a 2.0 8v your question is pretty vague

Align the mark (can be a dot or notch) on the intermediate shaft sprocket with the notch in the crank pulley. Align the mark (can be a dot or notch) on the "Back" of camshaft sprocket with the top edge of the valve cover gasket. Be sure all the timing marks are properly aligned.

For further information refer to Timing Belt : Service and Repair
NOTE : The 8 valve engine requires a special wrench, Volkswagen No. US4493 or equivalent, to adjust the camshaft drive belt tensioner. Whenever the drive belt is removed and refitted, the camshaft and intermediate shaft timing MUST be adjusted. The drive belt can be replaced without removing the belt sprockets.

1. Loosen alternator adjusting bolts and remove the fan belt.
2. Remove the water pump pulley bolts and remove the pulley.
3. Remove the upper timing cover bolts and remove the cover.
4. Remove the timing belt guide, if equipped.
5. Turn the engine by hand to set the No. 1 piston at Top Dead Center (TDC) and remove the crankshaft pulley.
6. Remove bolt and nuts securing the lower timing cover and remove the cover. CAUTION: Turning the camshaft or crankshaft with the timing belt removed may cause damage to pistons and/or valves.
7. Loosen timing belt tensioner locknut, release belt tension and remove belt from sprockets.
8. Inspect belt for visible damage such as missing teeth or exposed threads. Inspect tensioner bearing for smooth running. Any damaged components should be replaced.

NOTE : On high mileage engines, failure of the tensioner bearing is a possibility. Consider replacing the bearing when replacing the timing belt.

1. Align the mark (can be a dot or notch) on the intermediate shaft sprocket with the notch in the crank pulley. Align the mark (can be a dot or notch) on the "Back" of camshaft sprocket with the top edge of the valve cover gasket. Be sure all the timing marks are properly aligned.
2. Temporarily install the crankshaft pulley to the crankshaft. Fit the timing belt starting with the crankshaft and intermediate shaft sprockets. Fit the belt so that it is as tight as possible between the crankshaft and the intermediate shaft sprockets and between the intermediate shaft and camshaft sprockets.
   1. Turn the belt tensioner clockwise to adjust the tension. The direction is important to avoid contact with the timing cover. Check the tension by twisting the belt as shown. You should be able to twist it no more than 90 degrees.
   2. Tighten the tensioner locknut to: 33 ft lbs (45 Nm)
   3. Rotate the crankshaft two revolutions and recheck the belt tension and the timing marks for proper alignment.
   NOTE: Very slight movement of sprockets and marks can be expected as belt tension is adjusted. Slight movement is OK. The smallest possible increment of adjustment is one whole tooth of the belt or sprocket.
   1. Remove the crankshaft pulley and refit the lower timing cover. Tighten the bolts to: 87 in lbs (10 Nm)
   2. Refit crankshaft pulley and tighten the bolts to: 15 ft lbs (20 Nm)
   3. Refit timing belt guide, if equipped.
   4. Refit upper timing cover and tighten bolt and nuts to: 87 in lbs (10 Nm)
   5. Refit water pump pulley and tighten the bolts to: 15 ft lbs (20 Nm)
   6. Refit fan belt and adjust tension. Tighten alternator adjusting bolts.
