Help please Flashing coil light and EML on. Multiple codes 31391 27202 8208 8216 8217 8338

Ok so it’s back on but before I try to fit the circlip the workshop manual is saying to measure voltage via the diagnostic tool. Is this absolutely necessary and if so can vcds do it?

to check the voltage I opened vcds and then the engine controller. I selected output tests and then turbine actuator IDE07783. I figured this out by myself so it might not be correct but the voltage value changed as I operated the actuator with the mityvac gan

fingers crossed I got it right!

Stuffed some blue rag in the air pipes in readiness for the flying circlips!


But to be fair it wasn’t too bad and I had success with the 2nd one. God knows where the first one went! Trying to keep the mityvac pumped while manoeuvring some long handled pointy nose pliers with a small screwdriver in your third hand is tricky enough especially in a dark space with crap eyesight!

I’m out of MOT atm so just got to change the rear discs and pads and then go for test. I’ll then do a road test and log the values to make sure the turbos are boosting ok. If everything is ok I’ll wrap this up. Hopefully the thread will help others in the future.

Massive thanks to @mmi for all the help in getting to the bottom of it.
 
so how did you get on?

...

@rajjinator is doing the same job and is having some issues with the actuator length. . .

Sorry for the delay. I’ve changed the rear brake discs and pads, then taken the van for an MOT. It passed with no advisories but I’ve been so busy since I haven’t had the time to take it for a drive. Was hoping to hook up the laptop with vcds on its first test run just to make sure it’s boosting properly. I’ll get to it as soon as poss!

@Westcoast888 how tricky was this and why do you need the vac unit? It looks like my actuator has died as well...
Is it just the charge cooler that needs moving to get access?
Thanks

Sorry for the late reply. It was reasonably straightforward once the fault had been diagnosed. @mmi was very helpful in pointing me in the right direction on more than one occasion. You need the vac gun to operate the actuator to remove it and also to calibrate the new one. Worth buying one as they are very handy for other jobs such as bleeding brakes etc. also worth becoming a member so you can download the workshop manual. I’ve got an old laptop in the workshop loaded with the manual so it’s easy to refer to. I then use my day to day laptop for vcds.

Great result, and thanks for the detailed write up. I may need it it sometime ( but hopefully not too soon though)
Big shout out to MMI also, who is always a big help.

Thanks. I bit the bullet and had VW change the turbos. Just didn’t have the time or head space to sort it out myself. It financially hurt but the van was fixed within a week.
Thanks
