It's makes no difference if gear driven or belt driven you will have a problem.
Thanks mate for putting mind at rest lol
Bt if I got geardriven I only need the hex done yes?
Si
Did they replace it with the 100mm version?
Buy and fix with longer hex key and re manufactured balancer shaft that has a deeper recess at sprocket end.
Adverage cost for these two parts in UK minus the surcharge is £225.
Its the size of a small pencil,like the ones you get in screwfix.If they made it 10 or 12 mm + diameter it would never happen.
No because it would slip in the pump end then,and the money is the labour not the part in this instance the part is only about £20.So a bodger could just flip the hex around refit it and screw car back together ready for sale?
Sure a thicker one would help but the actual design fault is that the 6mm hex key isn't in far enough into the sprocket/gear end of balancer shaft causing a fraction of rotational play that eventually rounds off loosing oil pump drive.
Hence the updated replacement hex key is 23 mm longer and so fits an extra 23 mm further into a re manufactured deeper recess balancer shaft.

Exactly.A 12 mm 100 mm long harder hex key with re manufactured balancer shaft to suit would be bomb proof.

Hi, I have came across this too late unfortunately. My oil pump and turbo was replaced by audi 10 months and only 9000 miles ago at a cost of £2600. VW garage so 2yr parts and labour warranty. The low pressure light has just came on again, there is no oil pressure and car is back in audi to see if it is a valid warranty claim. I've checked the receipts and pump was replaced originally but cannot see any evidence of replacing the hex drive shafts!!! I am worried that it will not be covered under this warranty if it is the shaft that has failed this time but last time it was the pump itself. Surely they will have replaced the hex drive at the same time as the pump. 2007 2.0tdi brd engine. Car is booked in this weds need as much info as possible for when they try and wriggle out of the warranty claim.
Audi are now saying that the pump has failed due to a circlip failure and because the circlip was not replaced last time it is not warranty, plus turbo has gone again. offering me 50% goodwill gesture. they sent me a pic of the pump/failed circlip when i noticed excessive wear on the hex shaft which they had not even noticed( they said theyve reassembled with new circlip and oil pressure is fine ) see pic, this wear is after only 9000 miles. i told them i want this shaft replacing and want there opinion on the state of my balance shaft. Any ideas on why this shaft is so worn after only 9000 miles?View attachment 35141
