Oil Pressure warning and P0299 code

[RonB58]

Hi folks,
Audi A4 Allroad 2.0TDI.
Car has 110,000 miles.
Driving home today I got the Switch off Engine, Oil Pressure too low warning. Checked oil level (on the dashboard) and it said it was at Maximum. Waited ten minutes and slowly drove off.
There was a whistling sound then the car went into limp mode with glow plug light flashing, and oil light flashing.
Nursed the car home, only a mile or so, and there was some clanking and banging coming from the engine. I put another drop of oil (500ml) in and when I started the car the oil level gauge came on, showing 85% full. Put my code reader on and got P0299.

Car is still clanking and banging and I havent driven it again.

Could it be low oil pressure and this has caused turbo damage? Could a pipe have split somewhere near the actuator?

Dunno what to check!

Help!

Ron

What is it with people wanting to limp the car home causing more damage

It sounds like you've lost the oil pump drive due to the hex key having rounded off, this is known fault on 2 litre engine at that sort of mileage. There is a kit to upgrade the oil pump drive. If the engine is stopped immediately you might have been able to repair the pump drive and been lucky, but the drive home has now written the engine and turbo off. That fault code and limp mode is probably just a symptom of the turbo being seized or rattling round. If you want to check, drain the oil and look for bearing metal fragments, drop the sump and big end caps, remove the turbo compressor inlet and check for shaft seizure or excessive play.

Hi Rob,
Re: your comments oil pump drive failure!
Is this only relative to diesel variant 2.0 litre lumps or common to petrol as well? I'm inquisitive as my petrol engine is @ 100k +
