There are 2 plastic tabs, one on each side that must be depressed while pulling out. You could also use threadlock in addition. There are several T20 torx fasteners holding the plastic in place. Hyundai has released a technical service bulletin on this problem, which describes installation of an updated design timing chain tensioner part 24410-3C300 to correct this noise issue. This guide made my life so much easier, only difference i made was using 5mm bolts as i couln't get 4mm and i used nyloc spelling? Anyway now I've fixed mine, I do still hear the hoover sound, but about 90% quieter and less noticable. Please don't rely on my info here though.

Dec 15, 2013 Hello onarock844. On the driver side, turn the stick counter-clockwise. It is mounted inside the water pump assembly which is essentially buried in the front of the engine. If this has already been corrected,,,and the noise is coming from the upper engine area and not from the timing chain area, then the valve clearance will need to be adjusted. Be aware that this is an entire day job for a do-it-yourselfer. My car has done 94k and I can't really remember how long I've been tollerating this hoover sound on cold starts, but I'll be interested to see how it sounds tomorrow first thing I'd say this job along with throttle body cleaning is essential for any Mk4! The fuse box is located inside the dash usually drivers side.

It's only a standard 4 blade bosch relay. First of all you should look for the obvious issues like bad vacumn lines to the combi valve or hose connections near the pump but it was pretty clear I had a electrical issue. It is held in by a clip similar to a C clip with an elongated p … iece so you can pry it out easier. Once both are disconnected, hold the positive and negative leadstogether for 10 seconds. You unclip and pull the upper half away from the bottom. However, inthe even that the light was triggered by other work, there is ahard reset you can use to turn the indicator light off. I think for a while I kind of ignored it because it goes on and off intermittantly, as the engine warms up.

If this is not the problem, has anyone otherwise repaired or made their pump less noisy in another way??

Once refitted it is so quiet its un-true and the car runs so much better, the revs don't dip when dropping to idle, its revs straight through to the limiter with no flat spots and it does not hesitate when accelerating from cruising speeds. I used a small screwdriver to pry the switch out. The there's a heat shield that needs to be removed phillips screws.

Using scan tool, check Secondary Air Pump Motor V101 in scan tool Output Diagnostic Test Mode Secondary Air Pump Relay activation mode. This seemed to be the most solid part the jack could reach to. I would suggest also changing the timing belt as you will be pretty much ripping apart the entire front end of your car to get to the waterpump. If so you must reset your password using the process. The whole job took 2 hours.
