B8 Oil pump failure CAGA or not

Hope some techs that have done this kind of work might be able to chime in and help

Having watch the discussions regarding Oil pump failureswith the B7 does this problem affect the B8 CAGA engine? as summer is here and I don't mind getting a bit grubby if needed.
From what I can see there are two types of oil pump fitted tothe CAGA engine the 03G 115 105 H with a 77mm 03G 115 281 F follower drive shaftand the 03G 115 105 G with a 100mm 03G 115 281 E follower drive shaft.
My understanding is that anything with a 77mm drive shaft oilpump will fail at some point is this true? If so can this pump simply be


substitutedwith the later 03G 115 105 G with a 100mm 03G 115 281 E follower drive shaft or are there problems associated.
What is the general OEM pump Audi use Febi, SWAG
Also from what I can see there is no mention of replacement boltsneeded for this job, is this true or are some of the bolts a onetime use.

Many Thanks.

Hi Sacha35,

I found this post in another forum and thought it was a good read.
Could possibly have the answers youre looking for. https://www.audi-sport.net/xf/threads/2-0tdi-oil-pump-balancer-shaft-problems-the-definitive-guide-audi-vw-skoda-seat.140949/

I was under the impression that if the engine has balancer shafts...Its prone to failure.

Anyway, I thought id give you the link if you havent found it already.

Yep its the balancer shaft that needs changing and not the pump, just getting things ready for the swap over not that there is an apparent problem with mine but it states that the early CAGA has this problem with the 77mm shaft and this conversion makes it use the latter 100mm shaft which has no reported problems at present.

Even though this vid is not in English it is quite good and shows the extent of what has to be done, Erwin must be used and followed even though there are no official replacement VW balancer shafts only the complete assembly at £1600+

This is the part needed, not to bad for £197.75 (exchange) better than the £1600 for the complete replacement assembly.
