Oil Pump Balance Shaft failure

[defsix]

Hi,
Has anyone had an Oil Pump balance shaft replaced, or failed ? I know it was a problem with B7 2.0 engines and some early B8 3 code engines. I have a CAGA 143 and would like to know has anyone had a similar problem ? Or even replaced or checked it , replacing it due to wear ?

HI,

I would also like to know this. Can the B8 be affected by this problem? I also have a CAGA engine, and if i'm not mistaken the oil pump is gear driven(so no chain problems)8 but I would like to know if I have to do something concerning the Oil Pump Balance Shaft.

Hi I'm purchasing an older (2008) Audi A4 AVANT tdi 2.0 model which has the BRD engine code. It's done 83000 so the first thing I will be doing is taking it to a VW/AUDI independent specialist to view and replace the balance shaft and hex key drive as this is susceptible to wear at any point beyond 50000. Mine is also gear driven although I've had to speak to various people to verify this! Sorry I can't comment on your particular engine but if you're based any where near London it's worth contacting Ring Engineering (see their ebay page here VW Passat/ Audi A4, A6 VAG 2.0 TDI Re manufactured Oil pump balance shaft | eBay (http://tinyurl.com/hbxojp5)) or go to their website - they seem to really know their stuff regarding this particular issue. I will be purchasing the modified balance shaft and hex key through them (£210) regardless of the condition of the existing parts simply for peace of mind. Good luck

Is that in the B7 platform ? There seems to be very little info out there on it. All I know is a friends garage had do do one in a 2008 B8 , the shaft had rounded slightly and the engine was starved for oil resulting in a complete rebuild. Nice.

Yes mine is a B7 2008 2.0 TDI Sline quattro

Yes I've been eye balling my desktop screen for the last few days - what makes it difficult is verifying between the dates and engine codes. No Audi dealer technician for example - I tried 5 centres! could actually tell me with absolute certainty whether or not I had an older chain driven pump or the geared version (to be fair it simply wasn't logged on their systems when they keyed in the VIN number/ reg no which seems to be a legacy issue). Fortunately mine is geared as Ring Engineering immediately verified and while this doesn't mean it's fail-safe (I'll ask the technicians to check for any wear on the gears themselves) it just means focusing on the key drive and balance shaft upgrade.

Do you know the engine code? or what year was it?
I am concerned that this matter will start getting more and more frequent as more and more B8 start getting closer to "failure" mileage.

should everyone that has a 77mm balancer shaft replace it in the near future?

I didn't get it before it went back to the customer. It was a high mileage 250k KM. On long life services... So.

even so, 250k km isn't alot, I know many VAG with 300k+ km without ever changing anything inside the engine (1.9tdi and 1.9 SDI) ....
a broken oil pump shouldn't be something acceptable...

I agree with you, the 1.9 were a good engine. However the 2.0 are a bit different. Mines a CAGA engine are when I search for the Balance shaft online it mentions compatability with my engine code, however i've not found anyone else who has has this problem in a B8 (other than the one i'd seen). I would just like to know is it something our cars are affected with or was it just a once off ?

Ok, this means that we have a balance shaft, but does/will fail?? I don't want to be paranoid but better safe then sorry.

Someone had a close call the other day , did the prevention and the old 77 mm....

We have the shaft. The one I saw had slightly rounded as opposed to sheered. The engine appeared to have then been starved for oil, causing failure. ( Well this is what i was informed.) I did see the shaft at it did appear to be badly bruised.

Hi. I bought a 2009 a4 sline 2.0 tdi special edition with the cage motor. I was changing the cambelt a few weeks ago and also thought i'd check the balance shaft oil pump key way whilst it was in bits. I really didn't think it would be bad as it only has 80.000 miles on the clock. How glad was i when i checked it, i have photo of this to show anyone who might be on the fence about this and think mine wont be like that..thats what i thought!. My advice get it done just incase.peace of mind. The bloke i spoke to from Wakefield and purchased the new oversized key way and balance shaft from had a wealth of knowledge about this issue. He told me i am one of the 5% of owners who replace this before the damage is done. He told me he is selling between 10 and 15 balance shafts with new oversized oil key aweek and thats one company. Anyone thinking of taking this job on im happy to help in anyway. Just get in touch.
