How to check fuel injector values with VCDS (VAG-COM) for VW, Audi, Seat, Skoda

[@tudorstef5941]

Nice and eays. But how can i test the injectors flow on a 2.0 tfsi with vcds 21.3 ?

[@michaelbirchall2247]

That's great thank you. There's only 4 boxes, what happens with 5 cylinder engines?

[@CarDiagnosticBG]

This type of injectors can be tested only on test bench after removal from engine.

[@ermiasfikadu9906]

Hello sir, i want to ask you my Volkswagen polo 1.4 16v having problems with high fuel consumption and engine shaking when speeding i check everything is good but later i notice my 3 and 4 spare is lean condition 1 and 2 spark is good. Would you please give some advice thanks

[@willybaldsirhenry]

These are not injection quantity values, these numbers show the different amount of extra fuel the ecu is injecting in each cylinder to stabilize the engine. If the values are positive, it signals that the injector may be damaged or the electric signal is weak. If the values are negative, the cylinder is lacking fuel. Either injector is carbonized, or the fuel pump may be faulty. However you need to drive and log the values under engine load. Just to make clear. Great vid tho.

[@berczigabor]

No, these are idle stabilization values. They're only meaningful when the engine is idling, not when you're driving. Also, differences in them can have a lot more reasons than just problems with fuel supply or the injectors themselves. For ex. worn camshaft lobes or lifters (on PD engines), but carbonization of the intake ports and valves can just as much affect these.

[@willybaldsirhenry]

Gábor Bérczi hey Bro if your camshaft is worn out you will more probably receive an temporary MIL because the boost pressure is lower than expected when Engine is under heavy load. Additionally you will hear mechanical noises if a lifter is failing. But you are correct some measure values are only applying to engine idle mode. Logging a combination of common measure values under different load states still is your best and First option ;)

[@berczigabor]

@@willybaldsirhenry Cams have nothing to do with boost pressure. At all.

[@willybaldsirhenry]

Gábor Bérczi Again you are wrong ;) when your cam shaft is worn out the valves may Not Open enough or may Open too late which will result in an poorer exhaust mass hence your boost pressure may be lower than expected.

[@willybaldsirhenry]

This will also result in backfire to the intake manifold. Have a nice day and im out.

Ive got a problem with fuel dose, my car uses so many petrol, any advices how to change that in vcds?

[@andychapman5217]

Ive a vr6 3.2 having a slow start when engine is hot would a leaky injector cause this ive a vcds im goning to check them today...thoughts?

[@likezdislike]

Do you have videos for dpf and boost values?

[@Servicetutorials]

not yet, sorry!

[@hugogarcia7060]

Hello friends, I'm reading some of the comments, they're all good, but regarding this specific video, what @willybaldsirhenry says is correct. With this VAG COM test you can see the differences in spraying between one injector and another, it's very good data, but my question is, does the VAG COM give the real data in ml of how much is injected? And finally, what would be the number or quantity that an injector should spray, obviously each type of engine is different but with the VAG COM you can get this data connected to the car in question? Greetings to all.

[@andychapman5217]

Hi is this the same for the cylinder vr6 ?

[@risting-pc-service5150]

Why in my vcds this is this Meas Block is freezing ?

[@abdulbeany1894]

Hi my injection quantity is around 2.2 and it says it supposed to be around 3 to 9 what could be problem all 4 injectors are in range reading good thanks

[@colin5064]

So how can you alter these values if you need to ,if one or more cylinder is out of range?

[@MrBirol006]

Hi my friend.😊 Lower mg/str means that the injector is outting less fuel to the cylinder? Is this true??😢😢😢

[@mickmolloy6594]

Advanced measuring values doesn't show for each cylinder, just gives and overall figure, or am I missing something?

[@DiasDude]

i have to test it with engine on?

[@bojanbox8691]

The CAN protocol is unavailable to me, I only have UDS, so the "Meas_Block" option is also unavailable. I do not understand. I have a VAG of 18.9 and the car is a Passat b7 (2011 year)

[@rokmarkovinovic8653]

Box Box newer vehicles use UDS protocol and the classis measuring blocks is unavailable. However, you can go to advanced measuring values, which is same thing basically.

[@bojanbox8691]

@@rokmarkovinovic8653 Yes, you are right, but it was easier for me as an amateur to see the state of the injector through the measuring blocks. Now I'm not sure how to interpret the condition of the injector ....

[@bojanbox8691]

Da, u pravu si, ali meni kao amateru je bilo lakše da preko mjernih blokova vidim stanje injectora. Sad nisam siguran kako da tumačim i gdje da gledam stanje injectora...

[@ante2894]

Na toj verziji vcds moras na taj nacin. Kod mene u Pola je ista stvar. Ugl kad udes izbaci ti onaj malo prozor, u njemu potrazi izraze "injectio" stavis kvacicu na svaki injektor i dobijes trenutne vrjednosti u glavnom prozoru.

[@syedshahbazali1417]

I replaced my Skoda Yeti 4th fuel injector and while coding, when press the do it button, a dialogue box appears saying: This appears to be an uninitialised control module; Valid WSC/importer/equipment data may be required. Click Yes for vcds to use default values of 12345/123/12345 Click No for vcds to use values currently in the module , Click cancel to go back and manually edit the I tried both the yes and no options nothing works, engine won't start (was working perfectly before it was just a bad 4th injector but was working). I primed fuel as well. The car engine is not starting at all now seems like the coding is messed up. Any help would be appreciated. (VCDS is genuine - software, and cable both)

[@helleyequeue]

Mate the injector have a number on the top something like AS234SD you need to type it instead of the default 12345 that is put by default. Check how you can see the injector in VCDS and put the part number instead 12345 it's 2 min job. My car was starting when I changed the injector but it had a dash light till I coded it
