Could I buy something here, you pay for it, I post it to you? Seems like it would only be about 5GBP to send something like that.

 

@Pete_Ex-Wino : thanks and very kind of you but i am confused with the codes.

https://secure.lambdapower.co.uk/partsearch/az2.asp?manu=Skoda&model_grouping=Felicia

LP-18679 (rear) ,LP-42480 (front), LP-42481(front)

I don't see the LC-9586 although is here, the last on that list 6U0 906 265 E

https://secure.lambdapower.co.uk/partsearch/crossref.asp?idlist=SKODA

There's an NGK/NTK one on ebay for £58, not sure if that's a good price?

No I was going on 6U0 906 265 E (6U0906265E) that you or someone else put up and following the 6U being the code for your engine.

 

See my post on Sunday -  "Up to you which data(bases) you believe or disbelieve they all have errors and omissions but with a car the age of yours it is possible to have superseded part number - but I do not know if this is the case here - so more than one part available that are basically the same and will do the same job.  As your car is modified and 21+ years old it might be that you do not need to worry about getting the part with the exact original part number if that has been superseded provided you are careful about match the numbers and information."

 

This is the same as when looking at the information, databases and cross-references for the spark plug, and other parts, you have to make a decision based on the information available or get more information and cross-check all again.

 

For the 1.3 MPI, engine code AMH it has LP42481 - https://secure.lambdapower.co.uk/partsearch/az2.asp?idlist=LP-42481

 

You can go round in circles for a very long time.

 

I always keep in mind what Judge Judy says "No good deed goes unpunished".  😉

Does not ships to Greece.

This guy does. https://www.ebay.com/itm/154780308184?hash=item2409a012d8:g:7toAAOSwn8dh1EYQ

 

@nta16 : I asked the store for a clarification, i think too that LP42481 is the correct.

I was proposing to get it shipped to me, then post it to you. PM if interested.

It may be correct to their database but is it the correct one for you or the one you wanted as 6U0906265E, OZA457-I1.

This was the answer from the store

 

Quote

6U0906265 E is post-cat (rear) sensor

Pre cat sensor is on down pipe, round back of engine, facing firewall, before catalyser

6U0906265 C is pre cat front sensor

 

LP42481 is correct part

I do not recommend "universal" part for this vehicle.

 

The Lambda sensor that i have now is Bosch and 6U0906265 C , that's why the programmer suggested me to find the original, he was not convinced that was the proper.

The mistake was mine that i believed the guy on the VG group parts store.

 

Information can be confusing, mistakes can be made especially with or in the databases of parts suppliers and cross-referencing.  You done the right thing by checking the information.

 

 

As an example of the confusion this is what you get when doing a search on that site for '6U0 906 265 C'. - https://secure.lambdapower.co.uk/partsearch/crossref.asp?idlist=6U0+906+265+C&submit=Search

 

Only my guess but I might think the supplier's two different parts numbers go to the same two (NGK or Bosch Universal Part No. UN15) actual parts.

 

Personally (but I am not you or anyone else) I would be happy to take his advice and order the NGK (LP42481) from that guy/company Lambda Power dot UK dot com. - https://secure.lambdapower.co.uk/partsearch/az2.asp?idlist=LP-42481

 

I am used to these parts searches not always giving a straight or correct result but it is difficult sometimes for others to understand particularly those that want fast results, I prefer correct answers rather than just quick answers myself, many using the internet can get quick answers but whether those answers are correct or not is another matter (and I am not always totally immune from this).

NGK LP42481

 

 

Yes but are the same?

 

Brand: NGK NTK

Manufacturer Part Number: OZA457-I1

Short Code: 0414

Product Type: LAMBDA SENSOR (OXYGEN PROBE)

Quantity Supplied: 1

Hex (mm): 22

Thread Diameter: M18

Thread Pitch: 1.5 mm

Placement on Vehicle: Rear

Number of Wires: 4

Cable Length: 516

 

Or the LP42481 of that store is a different model?

You are on the roundabout again, you do know roundabouts have exists as well an entry.

 

As far as I can see from that site and on this thread, OZA457-I1 is 6U0 906 265 E so LC-9586 on that site. -https://secure.lambdapower.co.uk/partsearch/crossref.asp?idlist=OZA457-I1+&submit=Search

 

Up to you want you decide is correct.

 

*$c&*** computer playing up! now! 

Edited 13 April, 20224 yr by nta16

I asked the shop, the NGK OZA457-I1 is on the 6U0906265E but which is? LP-42481 or LC-9856?

No answer, so what must i choose? Why the store does not clarifies which NGK has?

There is anothe NGK in the market which covers the 6U0906265E is the No: 92142 (the OZA457 is No: 0414)

 

On the other hand, i asked 2 shops from Poland even the Ngk.pl which has a e-shop and i got no answer (they are rich as it seams and don't need my money).

LC-9586, according to this - https://secure.lambdapower.co.uk/partsearch/crossref.asp?idlist=OZA457-I1&submit=Search

 

and this. - https://secure.lambdapower.co.uk/partsearch/crossref.asp?idlist=OZA457-I1&submit=Search

 

The shops can only specify to factory standard car and parts and superseded parts, your tuner would know better with the modifications on your car and the tuning that he has done and the readings off the car, IIRC he said something like you should go to original which would be according to the bloke on the site NGK version of LP42481. - https://secure.lambdapower.co.uk/partsearch/az2.asp?idlist=LP-42481

 

Or it might be that we have been going round in circles so long we no longer know our arses from our elbows and we need others to tell us the difference.

I wrote all the details of my car and initially the Uk shop said to buy the LP-42481 (but did not wrote me which NGK is), when asked in the second mail IF this is the NGK OZA457-I1 then said to me to buy the LC-9586 (although again did not gave any details of which NGK is this).

If they don't want to give the specifications and have their own codes it's their problem and not mine. I refuse to buy a lambda sensor without to know exactly things about it because something similar happened here in Greece, last year he gave me a Bosch lamda sensors and few months later the same employee-same Skoda parts store he suggested me another Bosch (not the previous) and after research i saw that both weren't the proper for my car!

 

The programmer was sceptical about the Bosch and suggested me to buy the original (which was NTK) so i bought today from an e-store the NGK OZA457-I1 which covers the 6U0906265E plus it had some photos to check that is the same that my car had from the factory.

 

 

EAN 087295104149

Trade numbers OZA457-I1

Manufacturer Part Number 0414

 

If an e-store does not have pictures and does not clarify which NGK is of their own codes then he can keep the LT-4593 or the CD-6789 or the DR-9821 or the NB-2940 etc product as a precious secret same as the coca-cola receipt.

 

 

I am not defending the seller, it is up to him how he runs his business but if I have understood you correctly he already said which of his products he would suggest you buy. -

I do not know and only speculate that he has given no more detail as he thinks if he says exactly which NTK/NGK you will use that information to buy elsewhere having used his knowledge.

 

I am just as surprised as he probably was that you asked about, and have now bought, the 6U0906265E, post cat rear sensor, given the quote above but it is your car and your decision and perhaps the original 6U0906265 C, pre cat front sensor is more suited to factory specification original car rather than your modified car or either sensor would be fine, as long as it does what you want that is all that matters.

Euro II emissions have one lambda, Euro III have two.

The Uk store gave me 2 codes without saying which NGK is in each code. I need to know the full name of the lambda not just a code which only applies to the store's stock.

I have the E as factory from the first day 2000 till 2021, the chip was on from 2003 and no problems at all with the E lambda.

My mistake was that i replace it with a C (they gave it to me from local Skoda parts store) and i think due to this i have bad cold start issues.

Sorry my mistake I misunderstood and thought your previous concern was that you had been offered a Bosch 'C' rather than NTK/NGK 'C'.   Things now fall into place and make sense.

 

All being well you should get good results straight from fitting the new 'E' as the previous worked well for 18 years I can see why you would want to get it back and hopefully you have tracked down your issue and perhaps picked up some possible improvements from the other changes you have tried or will test. 

 

I certainly embraced the thread title.

 

ETA: I will now look at as many images of elbows as possible.

ETA:

An opportunity suddenly show up, due to the Easter or the 1st May i found that i can arrange a small trip to the country and that means: national road and sport driving in mountain routes so what's best to test the new lambda sensor plus to make it work with the factory spark plugs for many kilometres? 400 Km in a row would be far better than the few kilometres of home->work. That's why i was under pressure, i had to find a NGK lambda sensor according to 6U0906265E specification and have it in my hands shortly.

 

@Pete_Ex-Wino : thank you very much sir but the whole procedure plus the delay of paypal confirmation-delay from the seller to ship the item-you must go to post office--delay for the parcel to come to Greece etc very easily could get me off schedule. If i was not under pressure things would be different.

 

@nta16 : thank you very much sir for the suggestion of the Uk store but i couldn't risk to have in my hands a different sensor than the original, that mess of 2 different codes and the lack of information from the seller make me hesitate to buy plus i had the fear that the whole procedure with Royal Mail could take more than 2 weeks.

 

 

Gentlemen, from the bottom of my heart a big ''thanks", i feel much obliged to you both!

As for the record: Till Monday i will have the NGK OZA457-I1 lambda sensor in my hands and i will install it to the car the next days so i would be ready for that trip, first i will measure the fuel consumption on national road-mountain route and later will come the moment of truth, the fuel consumption on city traffic.

I have ''bet all of my money'' on this NGk sensor, if the combination of factory specifications lambda and spark plugs won't work as it should be them i think that for 99% i can not find the solution to my problem.

 

I think the new factory original fit NGK sensor might do it, to give credit where it is due, as spotted at the start of your other long thread by Papez, and recommended by your tuner.

 

As previous tests were done with the iridium plugs over national road-mountain route and city driving I would suggest you put the iridium plugs back in to test the new lambda as a one step change and test, plus you and your tuner were very pleased with the results with them and they might add a little more pep and fun to your national road-mountain route.

 

Enjoy your trip do the recording only as a very minor quick part of it, the underground, second(?) cold start is the real test which is when you are at work and you are not at work on your trip.

 

 

 

I can not find anything on the internet about OZA457-EI1A/01.

 

 

 

 

The new sensor is almost identical to the old one and this makes me extremely happy!

I do not know so just a guess, the 1A/01 part might just be a reference to packaging, that is it is not a box of 10 or 10,000 but a packet of a single item.

 

Good to see it has the anti-seize already applied and protected.

Yes @Papez mention about the Bosch lambda sensors that have reported with some issues but the problem was that i had already installed a Bosch. I trusted the Skoda parts store which gave me the 0258003745 although the same guy some months later suggest me the 0258003666 (both weren't the proper ones).

When the next day i got in my hands the old and i saw the NTK and checked the VW specifications (C instead of E) i said to myself ''oh, you step on it".
