1.9 Tdi PD - Limp Mode and EML/CEL - P0299 Code

DMCC · Aug 20, 2018

On my 06 mk5 1.9 tdi bkc engine code

Giving a code for p0299 on vcds

No leaks from boost pipes or intercooler
Actuator on turbo seems to be moving fine
Some oil/carbon buildup on the top anti-shudder flap hose joint
A bit smokey when being revved

Any ideas?

Actuator moves, but it's possible it's not moving enough.

If you get black smoke, probably is a leak.

If you get grey smoke, probably the turbo is dying.

Thanks.

I used some wd40 on the actuator today, as I couldnt move it by hand, it seems to be moving more freely but still quite hard to move? (im not familiar with these and how they should move)

I started it up and the thick smoke seems to have cleared, will take it out a drive tomorrow for an Italian tuneup to see what happens

Well took it out a drive the other day, but still smoking (grey colour)
No power, lots of grey smoke, high pitched whine when the boost is supposed to be on
Guess the turbo is a goner ?

Yes and check how much oil do you have on the intake before the excess oil causes major problems.

The stiffness in the actuator is usually cruddy vanes, sometimes the actuator will rust up. Keep working it by hand til it frees up. If it won't some have sprayed oven cleaner to get the crud off. If I was to advise, I always go with r+r.
The key is that the thing responds to vacuum. It should move over when start the engine.

Thanks, it was really hard to move at 1st by hand but guessing the ovencleaner done something as it is moving better, however I dont really know how much it should move?

I got someone to start the car while i observed underneath and it definitely moves when being started

Can you explain what r+r is ?
