@Ado1379  Sorry about the hijack Adam, but we did start with the best of intentions

Hi, did you ever find out which actuator was which? I still haven’t sorted this problem haha 

[Shahpor]

Hi Adam,

Yeah, if you look at the pictures posted, the one I mentioned does appear to be for the EGR cooler.

Sorry, but it has been so long that I can't remember exactly at what stage you are currently at

[Ado1379]

It’s fine, I haven’t done anything further since we talked as I was using my other car for a bit. Now I finally got Techstream working I can get a more detailed look into what’s going on. Also going to fit a new DPF and get the ECU sorted so it’s ‘legal’ again haha.

Ok so good news I hope.

Techstream has found a short/open circuit in the injection system and I have an error code for an injector too. 

I used the active test to individually cut fuel to the cylinders. And sure enough there was no change in the idling when I did cylinder 3. So this poses a few new questions...

firstly, if you take away all the stuff about thinking it was the turbo, could this explain my symptoms? (Loss of power, rough/jerky idle, slight knocking noise under the bonnet)

And secondly, is it best to get this injector repaired or buy new? I can code in the new injector with Techstream.

I can't really comment on which injector to get since I have never had to replace one.

However, it does certainly sound like it could be the cause of all your problems.  It would definitely be unlucky to have two faults appear simultaneously.

I would say that the best to get is a remanufactured one from Toyota/Lexus. It was cheaper then an aftermarket one.

When did you last clean the EGR valve? Any type of smoke from the exhaust?

Hi guys, I have same problem. Car was loosing power sometimes, I just spot and star again engine with push accelerator to red zone, then was driving normal until next stop. That was sometimes. Now when start engine I can drive normal fee minutes, the car loosing power and die, not going more than 2800 rpm. I got Tech Stream , no one error, I decide to cleane EGR, it's was blanked, I drived 100k miles was everything okay, now I can not find why is loosing power. Also cruise control light in the dash is not working  when car loosing power..  

I tried to drive and made screenshot with data from Tech Stream will atach here, can anyone tell me what wong whith the car. Thanks

[MirekDuda]

You see that in this screenshot?

Is showing exhaust back pressure - 750C all time , is that normal?

[MirekDuda]

according to data from screenshot atached can somebody tell me if SCV valve working normal or not? Thanks

Was not DPF. I don't know what it was, after long time off searching I just borrow Autel Reprogrammer and reset all system. Car driving well
