How to change filters in a volkswagen passat b5

Air filter replacement, drain cleaning, interior dampness issue.

Sequence of work: – Remove the decorative panel.

– Unscrew 3 self fixing the inlet pipe. Dismantle the branch pipe.

– Loosen 2 self-tapping screws fixing the heat shield. Unfasten the brackets fixing the metal vent pipe, if they are still alive on your car. If the brackets are broken there is no sense in loosening the self-tapping screws. Since all existing Passat filters have been changed not once the probability to see these fasteners whole tends to zero…

– Loosen the clamp, remove the rubber L-shaped connector from the return valve fitting. (Old nipples often break at the crimping point, there is air leakage. If the clamp is tightened too much the probability of destruction of the branch pipe increases).

Remove the connector from the solenoid valve of N-80 adsorber ventilation. “Pull” the rubber jacket of the valve from the plastic protrusion on the air filter housing.

– Loosen the clamps securing the “caterpillar” and the UHV pipe (remove the disposable clamp, replace with a worm clamp when reassembling). Disconnect the caterpillar and the IHB spigot from the filter housing. There must be a rubber ring between the connector on the filter box and the IHB spigot. When reassembling, grease the inner surface of the ring a little with oil or silicone grease.

– Remove the rubber stopper from the hole for the connector of the air pressure switch.

– Take off the connector from the air pressure monitor connector. (In the vast majority of cases, if there were naughty hands of service men in this unit, the fitting will be broken, as on the photo). The principle of fixing the chip is the same as on the ignition coils (Passat after 2000yrs). On AEB the connector is different, with a spring clip. It is even easier to remove.

– Unscrew the bolt fixing the box of the filter (head or wrench 10). Remove the wires and pipes away from the filter box area. Remove the box with an upward movement.

– Loosen 4 clips fixing the box cover, remove the cover. Remove the old filter element. Shake out the dirt from the bottom of the box. Clean the seat for the new filter.

Install new filter element.

– Reassemble in reverse order. When installing the box, make sure that the rubber feet on the box fit into the mating holes in the spar. 2.

2. I also noticed that the mats on the left side of the car (driver’s side and the passenger’s side behind him) are wet. No water underfoot, but the comfort unit needs to be kept dry. Went to study the forum for water. Here’s what I found: Water in the cabin, aquarium in the battery compartment and other drains

Decided to clean the drains under the battery.

– Remove the battery, which requires removing a bolt and of course remove the terminals from the battery.

Next, after removing the battery we will see the first drainage hole

After having looked a little bit deeper under the vacuum brake booster we will see one more drainage hole.

Since the sun went down, I decided to postpone the cleaning of the hatch drains for the weekend.

Can you tell me where else the water can come from? If you look at the car from the front, on the right side under the windshield is the hood opening cable, I shoveled 2 handfuls of earth from there, could it be leaking?

Can you tell me where it goes. It’s hanging in the air at all in my

I dunno, look at the diagram.

The hole is centered No bolt should be there?

we started with b5+ blue and ended up with b5)))

…and myself on a silver B5+… )))

I didn’t know what the box from the brains looked like 3 years ago.

Please tell me what kind of plastic tube goes to the filter you have in the photo where you say to remove the disposable clamp, is it svvc? How is it critical when it is disconnected and without a clamp? What does it do?

Reviews of the first owners of Volkswagen Taos 2021: real reviews

Thanks so much for the report, did the same thing today. But looking at the photos, I was puzzled by one question, he certainly is not about anything, but why the glove with the nubs out)))? Is it a technique, tactic, strategy, or just backwards?

you took off the spigot there was no rubber gasket inside?

sorry, i only took the valve off the air case, i did not look inside, i did not pull the spigot off it

I have a rubber bushing that goes inside the tube that goes to the air valve, I was wondering if you have it or not?

I can’t help you, I don’t know much about VGC in general… – I have one and I have not disassembled this unit, I just move it aside when I change the air filter.

Yep…not fun on lighters to change the filter….

About the water, if no one has yet climbed in, it’s definitely worth changing the gasket (or sealant) under the air filter and ECU.

It is not necessary to remove the window cover to remove the filter body. But if you take it off you can disassemble and lubricate the brake horn at the same time. Even if there is no problem with it (you will be surprised how it still rubs and works). If you remove the liner – be sure to buy / borrow a puller specifically for wipers. I almost killed a day to remove them!

Second problematic place – the door panels (more than sure that the water gets under them). Before you remove the door panels, I advise you to buy a dozen new pistons. There is a chance that they were there before you and half of them will be broken.

Good luck with the repair!

Thanks for the great comment, on the merits! I’ll start with gluing sealant under the ECU? The right side of the car is dry, so it does not pour under the cabin filter. As for the door cards, I hope they are not leaking, otherwise it would be a loss) No need to disassemble the doors.

Suspension of a Volkswagen Touareg: front, rear

Most likely the door cards! I didn’t want to get into the doors until recently. Thought it was complicated… All you have to do is remove the door trim. You don’t have to disassemble the door itself! Get yourself a set of plastic “picks” for the interior (cheap, easy to disassemble the interior quickly). It took me about 40 minutes to remove the trim the first time. Did everything slowly, to get a feel for it. After that – everything is much faster. All you need to do is unscrew 2 torxes, 2-3 bolts, unhook 6 pistons and disconnect the wires ;) Do not delay, Autumn will start to “float” … P.S. And yes, I just leaked from the driver’s side …

I also have extra noise on the doors. I don’t want to tear it off… How do I check if the door is leaking?

You could slip newspaper in. You could put something on the sill when it’s raining. You can take a hose and pour it over the glass (you need about 10 minutes. The gasket will soak up the water first and then start to leak).
