Assuming you are referring to the oil pump splined drive shaft failure issue:
The oil pump drive shaft failed on my 2L tdi passat (06 plate) at 71k miles, EWL came on and said ‘low engine oil pressure turn off now!’. I was in L3 on the M1 at the time in morning rush hour. Got off at the next junction and turned off (about 30 secs of running at 70mph). towed to a garage and ended up with new oil pump and new turbo, rest of the engine was (and still is) fine.
You can bypass this issue (assuming it has not already failed) by replacing the oil pump with the newer model VAG sell to get around this issue. could be a couple of 100 quid but you will then have an engine that shouldn’t suffer from this failure.
The new oil pump kit has a splined shaft that is a lot longer than the old kit so doesn’t round off and stop turning the oil pump!
