Oil Pressure warning and P0299 code

**RonB58** · 10-03-2017,04:58 PM

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.

What year is your car?

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 +

Diesel and only PD & CR 77mm oem , CR 100mm oem don't fail .

Hi Rob, sorry I havent got back to you sooner.
Even though the engine idles normally I know the turbo is shot, and possibly much more. It is with the mechanics tomorrow. I have to decide on my options here and you do seem to know what is going on with these engines. I can buy an engine (around 50,000 miles seems to be the norm) for around a grand, it will need a turbo and all the other bits refitted to it. I reckon it will cost me around £3,000 minimum to get the car back on the road. If I can get it on the road for that I will trade it in after a month or so. So in my position would you fit another engine, which has also the potential of the pump fail, or sell the car as a damaged repairable?
If I had known all this I wouldnt have bought an Audi, or this model!
Which engine is safe, if I was to buy another Audi? 3.0TDI? Or what car would you recommend, it has to be an estate with a bit of power.
Many thanks,
Ron

Sorry to hear of your predicament Ron, if you were to re-engine the car for 3k or so, are you better not just keeping it, running it a while to make sure the engine is ok, then getting the oil pump upgrade fitted? If you want rid then sale as a damaged repairable would save you hassle and additional cost (DMF, clutch, turbo, possibly on your donor engine). I've seen a pal spend thousands getting a ford engine repaired, only to trade it in losing thousands more in the process.
See what your mechanic says damage, wise but TBH i'd expect bad news.
I can't recommend any other car, they all have their weaknesses and faults! it's just finding out what they are and preventing or pre-empting failures. I can't comment on 3 litre tdi's from personal experience but it seems like modern diesels are so complicated and expensive to diagnose and repair and with the current anti diesel sentiment from the government and BBC, their days look numbered. Do you need a diesel or would a petrol be ok? I have looked briefly at octavia vrs estates to replace my estate.
I've got a 12 year old 1.9 tdi passat estate, been looking to replace it but really not coming up with anything better, the tsi engines have timing chain problems and I'm avoiding anything with dpf, but having just serviced and replaced all the brakes on the passat i'll likely just keep that another year or so.
Hope you get sorted without too much pain!
