Rear windshield washer Škoda Yeti - it would seem a trifle, but its malfunction can cause a lot of inconvenience. The problem is especially acute in slushy weather, when dirt from the road flies onto the rear window, and it is impossible to clean it. In 80% of cases, it is the nozzle that is to blame: it becomes clogged, cracks, or simply stops spraying liquid. Owners Yeti the first generation (2009–2017) encounter this problem most often - due to the design features and location of the nozzle.
In this article, we will look at how to diagnose a malfunction, select an original or analog injector, and also replace or restore it yourself. We analyzed owner reviews, technical manuals and service bulletins in order to collect the most useful information - without fluff and general phrases. If your Yeti stopped washing the rear window, you will find here step-by-step instructions with photos, nuances of choosing spare parts and tips on how to extend the life of the washer system.
Signs of a faulty rear washer nozzle
The first sign of a problem is when nothing happens when you press the rear window washer lever. But the injector is not always to blame. Before changing it, check:
- 🔋 Washer pump: Listen to see if it works when activated (a slight buzzing sound should be heard from under the hood). If not, the problem is in the pump or wiring.
- 💧 Liquid level: washer reservoir on Yeti located on the right under the hood. Sometimes the liquid simply runs out and the level sensor breaks.
- 🔌 Hoses and connections: a pinched or burst hose going from the tank to the nozzle can also be the cause.
- 🎯 The nozzle itself: if the liquid flows, but does not spray (or sprays at one point), the sprayer is clogged or damaged.
On Škoda Yeti Most often there are two problems with the injector:
- Clogging - due to low-quality washer fluid or dirt. Symptom: the liquid barely oozes out or comes out in a thin stream.
- Cracks or wear — plastic becomes dull over time, especially if the car is often parked in the sun. Symptom: liquid pours past the glass or the nozzle “spits” in different directions.
⚠️ Attention: If the rear window washer stops working after a high-pressure wash, it is likely that water has entered the nozzle connector or damaged the nozzle seal. In this case, replacement is inevitable - such nozzles cannot be restored.
- Clogged
- Cracked from time to time
- Broke after washing
- Pump problems

Original and similar injectors for Škoda Yeti: how to choose
On Yeti (5L) two types of injectors were installed depending on the year of manufacture and configuration:
| Nozzle type | Article number (OEM) | Manufacturer | Applicability | Average price, rubles |
|---|---|---|---|---|
| Original (VW Group) | 5Q0 955 991 A |
VW/Škoda | Yeti 2009–2017, all trim levels | 1 200–1 500 |
| Analogue (Hella) | 8GA 008 131-001 |
Hella | Fits all Yeti models | 800–1 000 |
| Analogue (Febi) | 27450 |
Febi Bilstein | Replacement for the original, tested by owners | 600–800 |
| Universal (for tuning) | VAICO V10-0544 |
Vaico | Fan type, requires modification of fastening | 900–1 100 |
Original nozzle 5Q0 955 991 A - the most reliable option, but also the most expensive. If your budget is limited, you can take an analogue from Hella or Febi - according to reviews, they last no worse, and sometimes even longer (due to more resistant plastic). Universal fan nozzles (Vaico) give a more uniform spray, but their installation will require slight modification of the seat.
When purchasing, pay attention to:
- 🔍 Marking: The original injector must have an engraving
VWorŠkoda. - 📦 Complete set: The box should contain an O-ring and a mounting screw (if they are not there, it is a fake).
- 🛠️ Material: high quality nozzle made of polyamide (PA), not brittle PVC.
⚠️ Attention: There are many counterfeit branded injectors on the market VW. They can be distinguished by their too smooth surface (the original has a slight roughness) and the absence of markings on the reverse side.
If you want to save money, look for used injectors at disassembly sites. But be sure to check its performance before purchasing: blow into the inlet - the air should come out evenly, without whistling.
Step-by-step instructions for replacing the rear washer nozzle
Replacing the injector with Škoda Yeti does not require special tools - just a Phillips screwdriver, pliers and 15-20 minutes of time. Work is carried out from the trunk side.
Phillips screwdriver (PH2)
Pliers or pliers
New nozzle with seal
Rags and cleaning fluid (WD-40 or alcohol)
Container for draining washer fluid residues (optional)
-->
Step 1. Preparation
Open the trunk and find the nozzle - it is located on the plastic panel under the rear window, on the left (if you look in the direction of travel). Remove the plastic cover by prying it off with a screwdriver (it is held on by clips).
Step 2. Removing the old injector
Disconnect the fluid supply hose (it is simply removed with tension). Then unscrew the fastening screw (it may be hidden under a decorative plug). Carefully remove the injector from its seat without losing the O-ring.
Step 3: Installing a new injector
Before installing a new part, clean the seat from dirt and remnants of the old seal. Insert the new ring, then the nozzle, and secure it with the screw. Connect the hose - it should fit tightly, without play.
Step 4. Check
Pour washer fluid into the reservoir and check the operation of the system. If the jet hits crookedly, adjust the direction of the nozzle by slightly turning it in the desired direction (it is fixed in several positions).
What should I do if the injector does not work after replacement?
1. Check if the fluid supply hose is kinked.
2. Make sure that the washer pump is working properly (ringing test it with a multimeter or apply voltage directly).
3. Inspect the fuse F30 (10A) in the fuse box - it is responsible for the washers.
4. If the nozzle “spits” air, it means that there is depressurization in the system - check all connections.
How to clean a clogged injector without replacing it
If the injector is clogged, but the part itself is intact, you can try to restore it. For this you will need:
- 🧴 Needle or thin wire (diameter 0.3–0.5 mm).
- 💦 Carburetor cleaning fluid or regular WD-40.
- 🔥 Syringe (20 ml) with a straw.
Method 1: Washing without removal
Remove the hose from the nozzle and connect a syringe with cleaner to it. Press the piston sharply - the liquid under pressure will pass through the sprayer and wash away the dirt. Repeat 2-3 times, then reconnect the hose and check operation.
Method 2. Deep cleaning with removal
If washing does not help, remove the nozzle (as described above) and soak it for 30 minutes in the cleaner. Then use a needle to carefully clean the nozzle hole, blowing through it from the back side. Do not use metal objects - they may damage the plastic!
⚠️ Attention: Do not use for rinsing vinegar or citric acid — they corrode plastic and seals. Also avoid compressed air (compressor), as high pressure can deform the nozzle.
If after cleaning the injector still does not work well, most likely the problem is a worn o-ring. Its replacement (article no. N 908 132 01) often solves the problem without purchasing a new injector.
Typical replacement mistakes and how to avoid them
Even something as simple as replacing an injector can lead to new problems if mistakes are made. Here are the most common:
- Tightening the mounting screw - leads to cracks in the plastic nozzle body. Tighten by hand, without force.
- Using sealant - some owners coat the seat with sealant, but this only aggravates the problem: later it clogs the sprayer hole.
- Incorrect hose connection — if you don’t put it on completely, liquid will leak under the trunk lining, which will lead to corrosion.
- Buying a nozzle without a seal - savings of 50 rubles will result in a leak and repeated replacement.
Another common mistake is not checking the pump. If the pump is weak, it will not be able to pump fluid through the new injector, and you will decide that it is defective. Before replacing, always test the pump by applying voltage to it directly from the battery (it should pump liquid even without a command from the lever).
On Yeti with the system Rain Light Sensor (rain sensor) after replacing the injector an error may occur B10D0 (“Rear window washer malfunction”). You can reset it through a diagnostic scanner or by disconnecting the battery for 10 minutes.
Prevention: how to extend the life of a washer nozzle
To make the nozzle last longer, follow simple rules:
- 🚿 Use a quality washer: Cheap liquids with a high alcohol content will corrode plastic and leave a residue. The best option is Liqui Moly Scheiben-Frostschutz or Sonax KlarSicht.
- ☀️ Park in the shade: Ultraviolet radiation makes the plastic of the nozzle brittle. If you don't have a garage, use a sunshade for the rear window.
- 🧼 Flush the system before winter: Before filling in the winter washer, run 1-2 liters of distilled water through the system to wash away summer deposits.
- 🔧 Check the hoses: Once a year, inspect the supply hose for cracks. Replace it if necessary (part no.
1J0 973 683).
On Škoda Yeti With rear windshield wipers, the nozzle wears out 2 times faster due to constant vibration. In this case, it is recommended to install a nozzle with a metal mount (for example, Hella 8GA 008 131-001), which is less susceptible to loosening.
If you often drive on dirt roads, install a protective mesh on the nozzle (can be cut from a plastic bottle). This will prevent sand and dust from getting into the sprayer.
Frequently asked questions (FAQ)
Is it possible to install a fan nozzle instead of the standard one?
Yes, but it will require some minor modifications. Fan nozzles (e.g. Vaico V10-0544) spray the liquid wider, but their nozzle is narrower than the standard one. You will have to widen the hole in the plastic panel under the trunk from 8 mm to 10 mm. You may also need a hose extension, as fan nozzles often have different lengths.
Why does liquid flow out in a stream and not spray after replacing an injector?
This means that the injector nozzle is not adjusted. The new part usually has a protective film - remove it. If the problem persists, carefully pry up the central hole with a needle (do not go deeper than 1 mm). Also check if the hoses are reversed (on some Yeti rear and front washers are connected to different pumps).
How much does it cost to replace an injector at a service center?
At an official dealership, the work will cost 800–1,200 rubles (plus the cost of the part). In independent services the price is lower - 500–800 rubles. However, the task is so simple that there is no point in paying for it: even a beginner can do it in 15 minutes.
Is it possible to drive without a rear washer?
Legally, yes, since the rear washer is not included in the list of mandatory equipment (unlike the front one). However, this is unsafe: a dirty rear window impairs visibility, especially at night. If the nozzle is broken and it is temporarily impossible to replace it, at least manually wipe the glass before driving.
Why doesn't the rear washer work in cold weather, but the front one does?
On Škoda Yeti The rear and front washers are connected to different pumps. If the rear one does not work in the cold, most likely the liquid in the hose or the nozzle itself has frozen. Try warming up the car for 10–15 minutes with the rear window heating on. In the future, use a winter washer with a freezing temperature no higher than -25°C.
