oh sorry dumb question the check engine light. From memory it goes off after starting, & no diagnosed fault codes show

What is the MIL light?

So after removing the PCV Assembly out yep the diaphram is split in 2 or 3 places. have ordered the replacement so hopefully will receive it over teh weekend & this solves the issue perhaps

quick one, but would a torn PCV diaphram cause this stalling issue? I am about to pull the PCV assembly out of the valve cover & see if its intact. I cant seem to find replacement diaphrams only online but cheap enough to order the whole thing. I'll update on tis in 20 mins or so

ive just ordered new coil packs so fingers crossed

its been suggested that the issue is with the " intake runner flap motor (V157) is mounted on the front‑right side of the lower intake manifold, facing the radiator. It’s a black oval actuator with a 6‑pin connector, sitting low and forward, tucked under the upper plenum easy to miss unless you look down the front of the engine." as far as i can understand it controls the internal intake manifold flap. I have searched for the actuator descibed, but i cant find anything mounted to the lower intake manifold. has anyone done this before with the black ABS plastic manifold, does the lower manifold need to be removed completely & if so are there any instructions available to do that

a bit of an update, have now repaced the camshaft control valves, i dont think this was causing the issue but needed to be done some time. also new plugs, cleaned & reset the throttle body, there was no obvious crud in the body & butterfly operated smoothly. overall removed cleaned & connected all sensor plugs & fittings. Still have the same issue, car starts first time every time but immediately dies. Have been able to look at the engine controol module data in live mode, fuel pressure reads around 105 initially, then drops away to mid 90's when it dies. If I push accelerator pedal down on start up I see the pressure is around 120 then engine dies again. still have some misfires registering. Is there a fuel relay(s) or the like that I can test. Is there an easy way to test the coil packs

Ive checked the plugs but not sure how to test the coil packs. annoying that it had been running perfectly up to this point, washed the car & then this issue appears. will start first time but only run for 5 seconds then dies. a while ago i had codes for camshaft adjuster control valves, I have bought these but not installed as the codes wnt away & car ran fine. will try to change these out this afernoon, not sure if they are removable externally or need to get to them inside the head

I dont have the VCDS software, ive been using an Autel Maxisys odbii scanner, where can the vcds software be obtained?

Hi All My 2011 superb 3.6 is causing me major headsches. Car starts great & then immediately dies. can start it again imeediately no issue but then dies again unless I push the throttle down & get it up to around 25 - 3000 rpm but even then it runs rough & will die again if revs drop Have replaced fuel filter at rear, ensured line from filter to low pressure sensor is clear, have fuel to the in side of the fuel rail(?) . no codes come up when interrogated relating to engine control etc. Is there an easy way to test the HP fuel pump is working correctly? any other thoughts & suggestions are welcomed. Do have misfires on nearly all cylinders when I can get ot to run on high revs.

Hey ex kiwi, Yeh I tested with all doors etc in their locked positions, definitely everything is shutdown, but do get an amp reading on the fuse for the radio circuit with everything else in sleep mode. Btw I have taken to a sparky & they're as perplexed by this as.i am

not sure of the make but it runs Android Infotainment. I have heard that it could be a canbus issue not shutting down the radio unit like all other systems when the car goes to into sleep mode after an hour? if so, can the canbus be replaced/firmware upgraded perhaps? Iknow of several other superb owners have had similar issues with this issue

fault code P0507/01287 displayed - idle control system - RPm higher than expected is displayed

Hello again another issue Im struggling with is the battery, even when replaced with a new one, goes flat after a day or so of no driving. I check the voltage after driving & it is fully charged. I have replaced batteries a couple of times. but the issue remains. I've opened thedoors bonnet & tailgate, witht hthe locks closed, left the car for an hour & 1/2 so that it shuts down, have looked at he amperage drawn across the fuses & found the fuse 17(?) under rthe dash is active. this feeeds the radio & fwe other bits & pieces. How canI make this circuit go into sleep mode with the rest of the car?

Hi All i have a 2011 superb Estate with the VR6 engine. when iat idle, it fluctuates between 1000 to approx 1500rpm, gets up to the 1500 aange & then drops down to 1000, continues to do this constantly doesnt make any difference wheter hot or cold, in gear or in neutral. Any ideas where to start troubleshooting would be helpful please
