motor factor site offering two fuel injectors part nos for 2011 Fabia VRS

What is the difference between 03c 906 036f and 03c 906 036m fuel injectors.

Im looking to replace the fuel injector in a MK2 Fabia VRS and i have found some site that say its OK to fit either the 03c 906 036 f or the 03c 906 036 m fuel injectors, are they correct... does anyone have any experience of fitting the F suffix injectors or are the completely incompatible (different spray pattern etc..)

any helpful 'technical' advice greatly appreciated.

The suffix-M part replaced the suffix-F part on 1st May 2012 in Skoda cars according to this site: https://oemwolf.com/oem-parts/03c906036f.html#replacements

So your car would have the had the F part when built, as it was before that date. (Unless there was yet another variant that the F part replaced)

No idea what the difference(s) may be, but in a car originally fitted with F's, the M's should be drop-in replacements.

If you look up via 7zap, it suggests buying the M part for anything up to 20/08/2012 build date (and suffix-N for cars from the next day onwards) https://skoda.7zap.com/en/cz/fabia/fab/2011-697/1/133-133055/

Welcome.

Are you dead sure that your CAVE engine car is running the engine it left the factory with 2010-2012. 

Not a replacement engine anytime in its life.  Be sure it is the Original engine before buying parts.

Thanks Wino and Skoffski for your replies..

Interesting about M replacing F suffix.. At this point I don`t know whats in the car (job for this weekend). I am the second owner of the car, (bought late 2017  60k on clock) but i know the engine was replaced under warranty in 2013 (at about 17k) due to excessive oil usage. (no longer seems to be a problem). ...  Im fairly sure that the injector in cylinder 1 is faulty.. (fault code indicating this using Ross-tech ),  My plan was to get secondhand injectors refurbished (mr injector https://mrinjectoruk.co.uk/) then swap over... I was going to by some suffix F injectors..I dont think i will now.. and look to do the work in two stages. (remove - service and reinstall ).

Just a point to mention I did have a remap early last year... this seemed to  the smoothness of pull away (cure the slight hesitation that seem to be there before)...  i guessing this will need re-doing after replacing injectors... 

Thanks once again for your advice BB

?

What spark plugs do you use and at what gap, and when were they changed.

& what about ignition coils, are they standard, original and all OK?

 

What Remap & by whom?   Has the car had a new Water Pump / Supercharger Magnetic Clutch?

You may find they are the suffix-N parts then, I suppose?

I think im about to be reprimanded slightly…. (and probably rightly so)..

 

We bought the car back in mid 2017 (mainly for my better half to use to from work (about 12m round trip), I guess I wanted something with a bit of performance, but had to be practical and reasonably cheap (I think we paid 6k)

That said when I do get to drive it .. it always brings a smile to my face..

 

Our local garage,  (Cedar rd garage Worthing) serviced and remapped it early 2018 (can’t remember who told me that the slight hesitation (delayed response to initial throttle) would be resolved by a stage 1 remap.. but needless to say the garage remapped it .. At the time (rather ashamedly ) I didn’t even ask who would do the remap.. I have subsequently found out it was done remotely by ‘Impact Tuning’ …

 

all’s been fine for 8 months or so (ignoring its probably been building).. in Nov last year the EPC light came on and due to a ton of work at home to do.. we took it back to the garage… £150 later and four plugs (Denso Iridium type) and one coil pack (Delphi), all seemed ok again….

 

For about three weeks… then EPC again… back to garage  £450 ..replace cam timing valve?.. changed oil and filter .. where unknown to me at the time (see next problem) they put to much oil in… it was over the to of the dip stick measure,  a week later (after ‘the other half’ had been driving it with to much oil )… EPC on again…. Back to garage ..

 

They tell me the injector (cylinder 1) needs replacing and to confirm and do this would be £450….  I have to say at this point , I would normally do most work on the car myself.. but as mentioned earlier ‘things have just been to hectic at home’ .. more fool me for trusting a the garage .. this time its to much … (not sure I will be going back ?) ..anyway I now find myself at the injector replacement stage  (will replace all .. not just the one that the garage were proposing)… But .. yes I’m guilty of not really looking into remapping further and other stuff I should have / should now do to the car to support it

 

All I currently know is the engine is standard (as per replacement under Skoda warranty)..   in 2013.. std water pump std, mag clutch.. etc

For this I deserve a bit of a berating!… I see some of must do mods heading my way (unless I return map to standard?)..

 

Cheers again (in advanced)  for you feed back

The concern is, or mine is.

The REVO Stage for a 1.4 TSI / TFSI 132-136kw Twincharger is crap, rubbish and aggressive, but that is only IMO obviously. & IME.

 

So what Remap has your car matters.

some others maps are rather crap as well.   

 

APR's was and is pretty good, but only IMO, and maybe others that have had APR Stage 1 or 2.

Remapping a good engine with a good map is not really a problem, 

the factory map / engine management, which ever they applied was crap.

 

The Water Pump is just something to be aware of.  They go sometimes about 35,000 to 50,000 miles and your water pump was from the factory in 2011.

Has the injector been actually faulted with a fault code ? or are they taking a shot in the dark ?

 

Could just be the coil pack ?

 

I would get the codes read "before" doing anything else ........as well as checking the spark plugs.

VCDS says injector cylinder 1 (n30),  P0201 00 [167] - circuirt malfunction  (according to garage this is typically an injector fault or possibably the wiring to it).... .. but i will check plugs and coild packs ... thanks  advice..
