only joking , its my brothers garage , its in the free - labour - bay. having cam belt ,water pump . new clutch and dual mass as it had judder in first gear , dual mass was knackered . then oil pump drive is been changed as they can fail.
fitted new dual mass + clutch , whipped cam belt off and water pump out . steam cleaned engine and box (not shown in pic) and steamed the engine bay as well .
need to get sump off in morning and swap oil pump drive ,then get it all back in .
not bad 4 hours work .
then its in body shop on thursday for the roof painting as some one intentionally scratched two U shapes in the back of the roof .
Christ ! at first glance on the first photo i thought the car was burnt out ! :0
thats a frightening sight!!
well its all back together again now. clutch is so much lighter even though is hydraulic no more judder and 1st gear engages without the notchiness. the oil pump drive was a close one .the balancer shaft was worn and the hex drive was badly worn out you can rotate the hex key in the drive by half way on each side . movement was like a spoon in a bowl of soup.
new water pump/cam belt . all filters fluids etc .
looked even worse at 8 oclock this morning sump off etc all in parts washer and steamed off to finish before re-assembly
Which engine? How many miles?
Mine is engine code cah 2.0 common rail .but it happens to all 2.0 tdi engines manufactured before 09/09
Needs checking with your vin as a 2010 car could easily have a 2009 engine .
Mine has 98, 000 miles but they've just had to swap a 77, 000 miles engine as oil pressure light came on 5 mins later engine was seized .turbo is dead within seconds when this happens.
So the 2008/9 B8 A4 2.0TDi 2.0L has the same oil pump drive issue as the later B7 A4 gear driven system in that the hex key wears.
What did you have to replace ? I'm guessing from what you said it was just the balance shaft and the hex key. If so won't the problem resurface later ?
Apparently the later (2010) Audi solution is a longer hex shaft but does that require a new balance shaft and oil pump or is just a new balance shaft/hex shaft.
Reason I'm enquiring is MY 08 B8 2.0TDi is due a new cambelt (5 years old with 49K miles). I'd like to get the oill pump drive fixed at the same time but wondering exactly what is needed to ensure Audi don't screw me.
1st point is if you go to audi for this done they will screw you . audi wont sell just the balancer shaft and hex key , they only fit the full oil pump cassette.
problem with the original balancer shaft is that were the hex key fits it is a loose fit and it is too shallow , the new balancer shaft has a very tight fit with the hex key , you can feel the suction when pulling the hey key back out of the balancer shaft . it also goes into the key way alot deeper .
im sure (not guaranteed though as i have a bad memory) that the shaft and hex key have a life time warranty. fitment of the shaft is easy .
the cost of the shaft/key was £250
Hollow, thanks for the info.
