BLB dreaded oil pump issue but advice needed

[chazd]

Query....brother in law has an A4 2.0 tdi. 75k and got oil pressure light on, limp mode and then pulled over. Common fault is oil pump failing on these BLB engines.

His local garage have said he needs a new engine but the car starts and can be moved (very low speeds) with no issues.

Do you think a new oil pump could resolve or would it depend on investigation when the engines out?

Im not so sure he needs a whole new block as if it was knackered it wouldn't fire surely? The oil pressure light comes on when the engine is revved to 2-3k and turbo spools

Stop starting it at all especially revving it, you are damaging the engine.
You need to take the sump off and investigate.

Vehicle has only been started to get off the trailer. Garage tested and advised about light coming on at revs.

Take the sump off, replace balancer shaft to later gear type, fit a new crank sprocket, new modified hex oil shaft and replace the turbo cartridge whilst you there. As mentioned above, the less you rev it more chances of saving the engine !

There is upgraded non oem tensioner , chain and sprocket etc from KMB Parts Direct as an alternative to converting to gear .

The weak part is only the tensioner breaking , a better one is a way forward at less cost .
