Hi folks, its been a while. I have trawled the archives but not found a definitive answer to my query.

I'm not much of a home mechanic nowadays, - prefer to leave it to the experts, however, the car has cost an arm and a leg recently so thought I would fit a new oil separator myself - straightforward job

The original part was still in place which is stamped 06H 103 495 A. I realize that there are several revisions of the part, and the one I ordered was a Febi Bilstein item, which on the box says it is equivalent to 06H 103 495 AH. The part was being replaced purely as a preventative measure on advice. The car was running ok. I replaced the part which was quite simple, and started the car.

I now have an uneven idle and when I blip the throttle, the rev drop to idle isn't instant, - it seems to take a second or two holding just over 1000rpm, before it drops to idle around 800/850rpm. Did around 150 miles yesterday and had no problem with performance.

I've just had a couple of hours trawling for info about revisions but have confused myself even more. I don't know whether the part fitted is wrong or faulty or whether replacing it has shown another fault. The info I can find seems to point to it being the correct part.

All advice gratefully received.

Genuine part 06H 103 495 AH would be the correct part.  But per other threads on these forums there are 2 simultaneous part streams for this part for this engine depending on original mfr date.   Based on my 2011 (now sold) my replacement was AJ having replaced the original part H.

 

But, for febi do they actually manufacture 2 versions or have they just merged into one part on basis that the bolts and part outline is the same?  I have replied to quite a few threads where people have had problems with pattern chinese parts and also aftermarket branded manufactured parts.

 

[Edit: Are you sure your car had a genuine part 06H 103 495A fitted. I don't ever recall seeing that as a fittment on the skoda CCZA, the part would of been E from my reckoning if original, genuine.]

 

Put the original back in, make sure it runs normally, and if so I would replace with a genuine part.  They are a 5 or 6 year replacement part.

Many thanks for your reply. Original is definitely 'A'. After much more googling I have found a different part on the Febi site and it looks like that is the one I should have ordere.   I want to swap the part anyway so I'm just about to order a genuine part from Coverdale. I'm not taking any chances this time, so I'm send reg, vin, and date of registration Lesson learnt and £40 down the drain !!

Cheers.

Suffix A version was superseded by suffix E on 1st April 2010, apparently.

That was replaced by suffix AC on 1st April 2014.
