Very interesting Turbo problem

[Ted Lindsay]

Hello,
So as you can see by the title I’m having a problem, on my previous posts I was having problems, my old turbo bearings had worn and the actuator snapped:

The new problem:
I replaced the turbo and now sometimes it completely stops, so I’d i accelerate I get no POWER.
There are no check engine lights or fault codes, related to the turbo, I use my little OBD to iPhone I bought specifically for this. I reset fault codes and it starts working, the errors I checked for were via an auto com machine at a garage.

Thanks, could it just be a sensor ?

What fault codes do you actually get then?

Well I still get P0011 and P2149 (when this happens it normally just misfires, so it’s not permanent)
Im just worried about the first one with the camshaft, everything has been changed, and apparently there is a map on my car, could this be causing the problem ?

It's not possible for the turbo to completely stop whilst the engine is running (unless your bearings have gone again). I think what's happening is that you're going into limp mode. It could be a bad map, but more likely a boost leak or a failed DV. The camshaft error code is usually either the sensor or the cabling to the sensor - check them both.

You need to take your car to an 8P specialist - where are you?

Hello, yes I don’t believe it is the bearings, it’s weird because when I reset via the app it starts working again. Do you really think a brand new turbo + DV + BOOST would break within 4000 miles. And the camshaft sensor is on the left side of an AXX right ?

Due to the fact your turbo bearings failed, and now you have a P0011 code, I'd wonder if your oil is clean, filter fresh and oil pressure good. Poor flow to the hydraulic actuator for the cams could cause rough idle and this P code. That could have killed the previous turbo. Was it flushed / new oil and filter etc and has the oil pressure been verified as good?

Hello, I’ve always had the P0011 code, even before it failed I believe. I just put it down to the remap.

I was there when the new turbo was fitted, the turbo itself was oiled, new oil through the whole engine + filter. I’m really unsure what’s going wrong with it, as it’s still new!

How new is the turbo - is it second hand and who fitted? Have you been back to the mechanic?

It’s refurbished from AET-TURBOS
I was at my normal garage, I helped with the whole process, and there was nothing installed on it wrong or any loose pipes etc.

Is there an easy way of seeing if something is wrong with the turbo without yanking it out again ?

You could have a worn oil pump or a partly clogged pickup. if the sump wasn't dropped I'd do that now and get a look. The older 1.8t had a sludging issue if certain grades of oil were used and mine went bang by blocking the oil flow to the cam chain tensioner. When we dropped the sump, just a few thousand miles into a flush and oil change, it was full of rubbery tar. The garage had used semi synth and it looked like it had been in there for decades. I'd honestly take a good look at the oil supply system.

Hi, thank you very much for that. Does the engine need to be hoisted to remove the sump ? People online are saying various things.
I can take it off and then just replace the pump, does this mean my turbo will now be ******** if it has been messing up the oil ?
