Skoda Rapid 1.2 l 75KM 35tys. - Landi Renzo MED 65 blue injectors - replacement?

Are the injectors replaceable? Any insights from other Rapid users or this type of LPG installation?
Skoda RApid- inst. Lpg Landi Renzo assembled before purchase in the showroom - installation of the so-called dedicated.
I am the 2nd owner.
For a guarantee of 8 thousand km, the injection rail and the tank's multivalve were replaced!
The current mileage of 35 thousand. km (100% original) and again the problem. The car switches to gas without any problems when the engine reaches above 55 degrees C oil temperature. The fluid in circulation is 90 degrees C much earlier than the oil reaches 50 degrees C. The factory installation switches to LPG at 40st. C fluid.
When left for automatic switching according to the controller, the car jerks for a moment, switches to petrol and the switch flashes with diodes as if the gas has run out. In addition, CHECK and ESP and sometimes ABS will light up immediately. Trying to force driving on LPG will worsen symptoms and cause the car to stop. After a successful switchover on a hot engine, there are NO problems with driving, neither with engine power, nor with gas consumption. Sometimes on a hot engine, for example after a momentary stopping and turning off the ignition, the symptoms are as described above on a cold / underheated engine to "full" temperature.
In the ASO salon they claim that Rapidy has a faulty assembly - the location under the hood of the injection rail and a different handle for the rail has been developed and the injectors need to be replaced with a new rail holder and adjust the installation. PLN 1200 + labor. They dragged me there for 2 x and I don't trust me. Hence the question, is it necessary, normal, others have it too?
During the first visit to the Dealership after the purchase, the discussion was not so much about damaged injectors, but about hoses / rubber hoses bending from high temperature supplying gas to the manifold from LPG injectors. and it is their bending that causes damage to the injectors with time.
Old cables had such a gray rim on top, stiffening them. During the first "on my own" approach to solving the problem with LPG, I replaced these hoses with non-bending, thick and stiff others and added thermal insulation to protect the cables / hoses from overheating. It didn't help at all. But it probably didn't hurt, fortunately. I am now thinking about washing these injectors or replacing them with new ones, but on my own. In the service, they will regulate the installation the most. I just wonder how much time the next injections will work. It's kind of paranoid. Before that, I had different cars and had NO problems despite the high mileage. In one AVEO I regenerated the evaporator, but that's normal. What's with this Skoda?
Is raising the injection molding. up closer to the mask will actually affect the temperature of the air flowing around it? Since the place of installation of the dedicated installation was wrongly chosen - the place was probably agreed with the LPG producer, then the DZIADY should replace / correct it for life free of charge.
I am asking for some advice / hint as to the cause of the fault / course of action.

Hmm ... It won't be possible to make a warranty claim, because it's not a new car, it's over 3 years old.
I went to the ASO because, apart from the normal service, there were a few other things to do.
Now, maybe I won't go to ASO anymore. Maybe, because I don't have a decent garage anywhere where I could easily leave my car.
I have had bad experiences with some of the neighborhoods. And with this SKODA Dealership it is the first time I meet such a hopeless service.
Generally, I am not quite a green man and so I know when they want to horse me. Besides, it is not always necessary to know to notice "kant". But I did not expect this from ASO. Enough about it.
SKORO it is supposed to be an ailment of the Rapids, there is probably someone on this forum who has already experienced something like this.
For now, I have just dismantled the rail and clean the injectors with isopropanol. One clean overall, one a bit dirty and the last C cool quite heavily. It seems to me that this may have an impact on their work. After all, their opening times are milliseconds. The top is easy to clean. After inserting them into the rail, I will let the isopropanol through the injectors with a slight overpressure and click on the opening of a battery. It is not the same as in an ultrasonic cleaner, but isopropanol dissolves these deposits very nicely (they are not hard, just sticky) so it should help. If so, I am wondering whether or not to improve this wash with acetone.
And in this annoying ASO they have labor rates of PLN 330 / manh! Not bad what?

Med injection is a terrible trash, I lost 32-35kkm in the roomster, I exchanged it for Keihin, but you can successfully replace it with barracuda or other. Cleaning is not good for much, the injectors are already "taped".
Read http://lpg-forum.pl/landi-renzo-omegas.html there are people who know their stuff.

I have red injections, I don't remember what company. They flew about 150,000 km on gas without starting. Now something is happening.

This dedicated installation may have the driver blocked. So you won't do anything. The older ones were unblockable. And you could put any injectors. You may have a problem with that.

Hello.
Something is actually wrong with Rapid.
I have 1.2 TSI in Fabia, but when I was on the LPG installation adjustment after 500 km, one of the ASO employees said that I did the right thing by buying Fabia, not Rapid.
Best regards.

Felerne Rapidy were - the first models after a small facelift with a timing belt. I don't think they had slack adjustments - but I don't remember that for sure.
I found the whole new strip with a Bosch sensor for PLN 670 with shipping and I think I will use it for now.
Because after cleaning the injectors, although they can be heard more clearly, the problem still occurs. It's just that to a much lesser extent. These injections are simply BADZIEWIE. I already had various lpg installations, but I have not encountered such crap so far.
AND THE MATTER OF ASSEMBLY.
I will write about it, maybe someone will benefit. Originally through the salon, the strip was mounted with the outlets slightly raised. Ie. generally flat - horizontally and about 20-30 degrees angle - upward inclination.
There was also no level in the second axle, despite the rigid mounting, There was a slight drop towards the last C injector.
PROPOSAL.
However, it would be most appropriate to install it horizontally along the longitudinal axis and at least with a slight slope down the transverse axis. And the ideal would be their vertical installation.
I will write how the car behaves after the replacement. First, no regulation.

Installing Landirezo is one of the best. I have already driven 160,000 on it and it's ok. In my opinion, the problem lies elsewhere. Landirenzo service in Mikołów. Good luck.

That I would ask. Have you thought about such a mundane activity as replacing the FFC and FFL?

I always think about such mundane activities at the beginning. Filters are changed more often than required by the service procedure. I only refuel gas at proven stations.
The fact is that I also had Landi Renzo at Fabia and the installation worked fine there. Injectors worked over 200 thousand. km and they were OK. Never cleaned etc. However, 3 evaporators / reducers were installed at that time.

I bet on injectors. Often there are problems with Meds. Maybe an exchange for, for example, Barracuda? They will go on the Keihin setting.

MED injectors are very good and durable, and the vast majority of their premature failure is caused by improper assembly, which causes contamination in them. This injection rail should have the smallest possible deviation from the vertical and if we install it in this way, it usually does not pose any problems. The gas, however, differs in the amount of impurities, especially oily substances, ie plasticizers and oils that have "attached" to it during distribution. Therefore, I recommend refueling at the stations of reputable networks that have their own distribution channel. This does not mean that the gas will always be perfect, but the risk of regular refueling with low-quality fuel drops significantly. MEDs, which start to cause problems at low mileage (20-30 thousand km), are usually mechanically worn, but simply stuck inside, and - unfortunately - cannot be dismantled. Specifically, I should say this: non-collapsible, because everything can be dismantled. You can try to clean them by cyclical actuation with the simultaneous supply of a washing agent under pressure, and sometimes it gives a good effect.

I came to similar conclusions as I wrote earlier. As close to the vertical as possible = best.
Nevertheless, I still cannot understand why the ASO service in consultation with the LPG manufacturer (in this case Landi Renzo) developed such a faulty assembly concept? SKODA and LR = thus no respect for the customer.

I use the best gas available according to my opinion, regardless of the price.

The method of installation in the ASO of a dedicated LPG installation for Skoda Rapid 1.2l MPI 75KM. The view under the hood. Same everywhere - C injection lowest (first from right), injector outlets level / slightly up.

There is no pressure measurement after the filter?

On the right side of the injector rail. Bosch sensor.

Horizontal / vertical injections after a minor modification. Hoses supplying gas from the injectors to the manifold are reinforced with wire springs preventing deformation from increased temperature. Stretched high-temperature insulation material on hoses with springs. I do not know what it is, but the car starts to switch to gas normally.


I made an appointment for diagnostics on the lpg service. I resign from the current ASO.
They lie, they don't respect the arrangements, they don't meet the deadlines.

Let my friends let me add 2 words, because I can't read it anymore ...
The problem described by the forum user is in 99% caused by the dirt on the LPG electrovalve pin on the reducer. The described symptoms have nothing to do with injectors, which are usually replaced without sense, because one of the experts threw such a slogan and it went on ...
I would also be careful with washing the injectors .. and certainly nothing that dries out .. because they simply rub and will not close enough .. which will increase their efficiency in an uncontrolled way, especially in transients, during acceleration and in cut-off . It is also easy to destroy internal rubber seals sensitive to active substances.

Well ... I do not know how it is with these injections, but I have not seen such a limp as this Landi Renzo installation in THIS Skoda so far.
Such times now that it's best to know everything yourself, because otherwise it is expensive and also bad.
And the Skoda Dealership, which I strongly recommend avoiding, is Skoda Bednarek (JTB) Łódź, ul. Szczecińska 38. I have very bad experiences with them like almost nowhere and never in any workshop - from a garage in a garage to an ASO. Only the service and dealer of ASO Chevrolet in Siemianowice, which used to sell patched and painted cars as brand new, was worse. Thank you for all the hints, I close the topic.
