P200A is easily fixed by using LiquiMoly Diesel Intake cleaner. One can through the turbo intake and a second can through the intake elbow after removing the straight hose under the battery. No need to remove the inlet manifold. I use GDS2 to hold rpm at 2,000. Cheers

Hey Ripahh, I agree that a cleaner can be used as a maintenance program, but from my experience, the only way to clean out large amounts of carbon is to remove and ultrasonically clean the components. You also have to keep in mind, with an intake cleaner, all the carbon goes past the inlet valves and seats, up and down the bore, out the exhaust valves, past the turbo into the DPF. This can cause major issues with large amounts of carbon. Also, carbon is very abrasive, so can cause damage on the way out. But yes, for maintenance, trying to stop a build up of carbon before it becomes an issue, I agree. Thanks for your comment 😉👍

@@MiracleMAX for my “off road Captiva” I flashed the ECU with DPF/EGR off. I removed the EGR cooler completely and used a delete pipe from Italy to replace the DPF. I also removed the Swirl valves from the manifold. The result is 525nm TQ up from 425nm. Fuel economy is now 8lt city and 6lt highway. No smoke from the exhaust unless flat out. It smoked with the DPF also. Boost up from 20psi - now 25psi. I know it’s in your best interest to overcharge customers to manually remove soot etc however LiquiMoly is proven DFP safe. That code WILL go away immediately. Cheers.

Diesels don't operate the same as petrol engines with a throttle blade. Most Diesels don't have a throttle blade to pull against to create vacuum, that's why they have a vacuum pump to provide vacuum for things like the brake booster. If they do have a throttle plate, then this is used for EGR operation. Diesels will not have the typical 17 and 22 inches of mercury that you will find on a Petrol engine.

Hey Ritchie Jarvis, Is the DPF being regenerated on a regular basis? To be very honest, carbon build up will not be removed efficiently by an additive. Also think about it - that hard, abrasive carbon if it is dislodged by an additive has to go somewhere. If it is in the inlet system, it has to go past swirl flaps, EGR valve, inlet valves, near piston rings, up and down the bore, past the exhaust valve and through the DPF and possibly a catalytic converter. I have removed and ultrasonically cleaned inlet manifolds, EGR valves, rocker cover (which is part of the inlet system) and other components on a Mitsubishi Triton and I would hate to think of what I got out of these components going through the engine. I believe the only time an additive is OK to use is as part of a maintenance program when the carbon has been removed. As for using a 'cleaner fuel', the same issue applies. Fuel here in Australia is not good quality and just one of the reasons we suffer from huge carbon issues. Once the carbon has been removed, regular maintenance with quality oil, consistent fuel filter replacement is a start in the right direction, but it is not the ultimate solution. Sorry Ritchie, there is no simple answer.

Hi Max, Your video is very informative. I have holden captiva cg2 2012 diesel. I m getting light with the following code. Egr valve p0404 Engine coolant sensor ect p0118 Can you kindly advise.

@MiracleMAX

Hey max580, There are several reasons for those codes. Firstly, what sort of scan tool data do you have? Do you just have a code reader or can you access 'live data'? What is the coolant temperature reading on the scan tool? Do you have 5 volts at the temperature sensor? Does the voltage drop as the engine heats up? Secondly, the P0404 code is EGR related, but can include things like carbon build up, which can mechanically jam the EGR valve, not allowing its full range of travel. Have you removed the EGR valve to see any carbon build up? Have you checked the intake system for carbon? Does the vehicle have any symptoms apart from the check engine light and the codes? Does it run rough at idle? Does it lack power? How many kilometres have the vehicle done? Has it been serviced regularly according to the manufacturers recommendations? Hopefully that will give you a direction to diagnose your fault codes. MiracleMAX

Hey kata atak Welcome to the channel! Is your vehicle the same as the one above? Is it only above 2,400 RPM that the fault occurs? When you look at live data, is the boost desired the same as the actual? Now that you have cleaned the EGR valve, are the desired and the actual readings the same? The same applies to the intake runner - are the readings the same. Does your vehicle have a DPF? With your scan tool, check and see when a regeneration was done last on the DPF.

There is no boost to waste at this point. Desired turbo wastegate position ............Once again, strange that the ECU is asking for the wastegate to be opened at idle Intake air temp 17°c outside temp 13°c ..............you will see a slight rise in intake temperature due to the heat soak under the bonnet. Maf reading 13.21g/s ..... Although this seems a little high, a turbo will read higher readings at idle. That being said, if the boost is being wasted, you wouldn't think the MAF would read that high. Do you have EGR data at idle & revs (2000 RPM)? I would focus on the turbo readings at the moment. Is the waste gate working correctly? When you turn the engine off, can you see the actuator move? Can you test the actuator with a Mityvac? Does the data move when you raise the engine RPM? Check and see that there are no split hoses. While you are there, have a look at ALL the vacuum hoses. Have a look at the bulletin I listed in the description. Check for free actuator and wastegate operation. If this has a DPF, it should have a Differential Pressure Sensor. There should be 2 hoses going to the DPF, one to the front and one to the rear - work checking out.

Man these things are absolute buckets. For some reason my boss bought one as a work car and now it’s crank angle sensor is faulty. Took it to a workshop, they replaced the cam sensor and said it wasn’t the crank angle sensor but the wires were faulty. I picked through it all and they weren’t, so I got some cold water and tipped it on the crank angle sensor, fires right up. So another workshop doesn’t want to do it, so I ring Holden to have it fixed so we pay book time. Holden says no, not faulty. Fault code says cam sensor, and when you research if the cam sensor is replaced, and it’s not receiving certain voltages, then it’s the crank angle sensor. We can’t do it at home because it’s an AWD and apparently the gearbox and transfer case need to be removed to replace it, and you’re looking at 6 hours minimum to do it. Cannot find any info on the motor at all, it’s a 2.2 turbo diesel Captiva 2 5, but all you find is one that you can pull the turbo pipe off and change it, where as ours is on the firewall side of the motor. Total, utter piece of shit, up there with the worst cars ever made.

Hey DIY Mechanic, Let's see if we can diagnose this together. Firstly I'll need some more information: Is there any freeze frame data attached to the fault code? I gather your engine is a diesel. Can you see in live data what the soot accumulation in the DPF is & the last time it did a regeneration? Has the intake system every been cleaned of carbon build up - preferably ultrasonic cleaning? Is the EGR valve target and actual the same or close? Is the turbo operating correctly if you look in live data? Are the swirl flaps physically moving OK? Also, look for any intake air hose leaks. These are notorious for splitting between the intercooler and the throttle body. It's a hard hose to get to and is easily missed. Do you have a smoke machine you can use to test for intake leaks?

How many kilometres has the engine done? Has it been serviced regularly? Has the correct oil been used? Do you have a scan tool that can see if the vehicle has done regular DPF regenerations?

@@Genove82 Have you checked the EGR operation? Are there any vacuum leaks? Are you able to do a smoke test on the intake system? Is the engine mechanically sound - has a compression test been done or at least a relative compression test?

@@MiracleMAX I made some measurments with a Delphi Diagnoze and here are the concludions: -the desired boost with measured boost in low throttle demand are not the same,40 kpa difference but on heavy throttle with high pressure demand its much better with low difference -i observe that Intake air flow,valve position the value is 100% with no cheange during acceleration and at idle.this is normal? -with engine at idle i unplug the vacum pipe from intake air flow command valve and i see no movment of the command rod,this is also normal?

@@Genove82 So is the swirl flap command changing from idle to revs? What about during start up? During a road test? The vacuum hose that goes onto the flap actuator, will have vacuum supplied from a solenoid. When you turn the ignition 'on' generally you will see the actuators move back and forward, doing a self test. Does yours do that? Also is there vacuum being supplied to the solenoid? Does your scan tool have 'activations'? If it does, you could use the method I showed in the video to test the command side of the ECU.

Takes premium diesel fuel only right... ppl don't realise that you cause more issues on these new diesels (all common rail) when using standard diesel. Maybe it cost less per litre to use standard diesel fuel but not in the end when it comes to repairs and down time... not to say this is the precise cause in this case but its worth considering, isn't it.
