yes very lucky you did not damage anything.... just to be more precise it is not recommended to convert a chain drive oil pump to a geared one, best is to start with a geared oil pump as the shafts have their own gears the other way around....

Hi everyone, I recently joint this forum, I both in November an A6 2L TDI (BLB) 2006, avant S line, it has now 106500 miles, I had it remapped to 390 nw/170 bhp, As a preventive measure I changed the oil pump to a geared one and upgraded the hex key and shaft hole, I am intended to keep this car...

Hi Josef, Paul would probably confirm, unfortunately soon or later you will have a wear to the hexagonal key and slot shaft, Being a BLB, it is likely do be a chain drive , unless a previous owner already converted it, the only way to know(has Paul mentioned) is to remove the sump to check...

one other thing, it is not a good idea to use shafts from a chain drive oil pump to convert it to gears, for the shafts to spin in the same direction as the chain one because there is a gears in between crank and oil pump (3 gears in total) it reverses the spinning direction, the gear oil...

sorry if there is a miss understood mine is a BLB, and of course I am converting it to gears ... some further research on the wear and it may seam obvious; the shaft and rod would wear because of all the permanent shocks between them, it's just a weak design, I think they are all like this the...

Decision;I not sure of the insert method, insert & weld, metal liquid repair or the 100 mm long hexagonal key ...I went for the oversized hexagonal rod , basically they make a new rod witch is bigger at the shaft and they oversize the shaft key hole, there is someone from Irland that advertise...

Hi everyone, my sump is off; after 105 000 miles I was very surprise to find the chain and tensioner in good condition, I am obviously not taking any chances and converted to gears; we also took apart the oil pump and find a slit wear on the hexagonal rod, but at both end at the shaft and...

I have been reading the last 15 pages.... I think the quality of the late OEM 100 mm hex rod & shaft is still poor, there is probably a few reasons why they wear out; slack fit, soft metal on hard metal, size and length, ect...I will get in touch with my local engineering company to understand...

I am confuse to what is the best way some engineering companies repairing the shaft hex key hole, some engineering places press an insert & weld and use a hard metal key but still in 77mm long some just press but do not weld, and still use a 77 mm key OME some repair it by using liquid metal &...

I started the engine today and had a good listen cold & hot,As far as I can tell, I have no noise, by the way the car with the remap is absolutely superb to drive. just some vibrations (witch I will get checked, flywheel, engine & gearbox mounts, cam timing, ect...) I have an appointment...

just been reading a few people with 07 (170 bhp ) cars had the same issue , it's rather confusing; are the 2007 BRE engines still fitted with the chain oil pump ? thanks just came a cross on ebay with a company that refurb and convert oil pump to gears, "power max engineering" I though for a...

Thanks a lot, I will ask the garage what's the cost to check it, in the mean time I have asked Audi Stratford that did most of the services to dig me all the invoices ....and I email the single owner of the car... Konstantin

I phoned Audi this morning, and give them my vin number to find out if my engine was fitted with gears or chain, and they could not tell me, they said you can not even tell from outside you have to dismantle the oil pump unit.... does anyone have more info ? my VIN numero; WAUZZZ4F*6*063423...
