Hi all

2015 Skoda Octavia 230 VRS
Recently I have had an EPC light pop up while pushing the car. The car immediately cuts all throttle and only restarting the car removes the issue. Upon scanning i get the P11xx implausible signal from Cam Adjustment Actuator for all cylinders.
This likely is pointing towards failing camshaft magnet actuator.

Now here is the issue:
The part on my car is: 06L 109 259 A, see attached picture
When you search for replacement parts one of the choices you get is INA 427 0034 10 which has a part number on it 06L 109 259 E
Now i know that parts get updated over time (hence A, B, C... variants), but the issue here is that construction is not the same.
INA part i doesn't have a full metal disc, but rather a metal disc surrounded by plastic. Also it doesn't have two holes in front like the original does. I presume the holes are for oil, but i have no idea what purpose the oil has in a magnet actuator.
Anyway, check out the second image of the E variant.

My questions are as follows:
- Will the new revision function correctly? I'm sure the magnet does the same thing, but the lack of oil holes is somewhat concerning (why would there be holes if they are not needed).
- Could it be that the revision removed the holes because it gunked up the actuator and made more issues than it fixed? Is this why they fail?

Any experience or info is much appreciated. Its not nice to loose ALL power when you expect it let alone when you need it. :(

Also, I'm fully aware i can just buy the genuine VW/Skoda part but the difference in price is literally 3-4x and i know INA is the manufacturer of camshaft magnets for VAG. So instead i decided to save some cash and replace it with a headache (dont judge me :D ).

Kind regards,
J

Reassuringly, if I search partslink24 for 06L109259A for a 2015 Octavia, it shows as being dropped on Apr 1, 2018 and superseded by 06L109259E.

£58.60 + VAT each at Skoda.

AfIk ina is the oem supplier. The oem and genuine part should align in design, perhaps with some delay.

I,ve replaced both my electro magnets, with Ina items. About 3 or 4 years ago, at that point, the oem ina item and oem were the same form and design, with a large metal chamber and two holes.

One word of caution, what exactly is your error code, as it sound more like the variable lift system rather than variable timing advance.

I got the same info, but what i cant confirm is if the E is physically different from A. When googling the E part both designs pop up, so im just trying to get confirmation that the E is indeed a newer design that is different from A.

Now that you mentioned it, i might be wrong, it does seem to point to a different problem, that i diagnosed wrong. The codes i get are:

the E is indeed a newer design that is different from A.

If it wasn't different in some way, it would not have a different part number.

Those faults are to do with the valve lift system, not variable valve timing.

The fact that all 4 cylinders are reporting intermittent faults suggests to me it is not the actuator themselves.

Need to check wiring looms, plugs as first step.

You are correct. The web also suggests the J757 relay that could be dying.
