P200A75 Fault code (OM651 Engine)

[steve gooding]

Evening people, looking for a bit of advice please.
With the current lockdown I haven’t needed to use my car for the last 2 weeks. Today I started it, just to run it up, put a bit of charge in the battery etc. Anyway I lifted the bonnet while it was running and couldn’t help noticing what sounded like a vacuum leak coming from the inlet side if the engine. Obviously you can see absolutely nothing, so looked on net for anything similar. Cracked manifold is what I kept reading, but if this was the case you’d have boost escaping when the turbo spins up. So I took it for a drive, windows down but couldn’t hear any hissing that is consistent with a boost leak.
So I plugged in my cheap fault code reader and it logged the above code. P200A75 - intake air control actuator performance problem.
I have looked into this and other people who have this code get all kinds of running problems. Mine still runs fine, no smoke, no performance drop off, turbo still boosts, mpg still seems ok. I’m guessing it’s either the flaps on the inlet or the actuator motor itself. It doesn’t appear to be run off any vacuum, so I’m guessing the hiss i can hear is the flap stuck open?? Maybe, or am I barking up wrong tree completely?
While I don’t need the car it’s and ideal time to look at it, but not sure how to check if it’s the flaps sticking, or the motor not working. Or should I leave it until I get noticeable running problems? It looks like a right pain to get at.
Any tips appreciated.... thanks

Steve

Steve, the code you pulled I think is "The charge movement flap (cylinder 1) has a malfunction. The emergency position was not reached" or similar. I usually see this on mine any time I check the codes. My van runs with no problems and I haven't bothered to sort the problem and its going on at least a year to 18 months. I haven't noticed any vaccum leak sounds coming from mine but then my hearing isn't good on that sound range. It is a real pain to get at as ive inspected the area when i had injector problems but backed out of it at the time as I had other more important issues with the van.

Just a quick update.
This morning I thought I’d have a quick look to see if i could find anything. Firstly I cleared the error code.
Checked all vacuum hoses and inlet. After ripping my hand to shreds trying to feel around for any holes or traces of oil, I gave up. I managed to find all inlet bolts, none were sheared. I got my phone down in the gaps to get some pics, but not all were clear. So I’ve come to the conclusion that as there were no traces of oil, the manifold has no cracks or holes, vacuums hoses all look ok, maybe the suction noise has been there all along and I’m just being paranoid? (I always think the worst when a new noise occurs).
Ran the car for a bit, re checked for the code and it hadn’t re appeared. You can also hear the flaps in the manifold when turning ignition on and off.
I’ll leave it for now, but will keep checking for the code.
I may visit MBS when all this madness is over just for peace of mind, but fear the worst that they will find something bad ...

Thanks for looking.
Steve

If they are leaking, they tend to blow oil all over the inside of the EGR cooler on the right hand side.

If you have no issues, no codes re-appear then I would think there is no issue, and the noise is maybe the alternator working harder than usual due to low battery etc

That’s a good point. Car isn’t being used so battery could be low on charge. In fact it was quite slow turning over this morning.
Saying that the noise is coming from opposite side of engine to where the alternator is. But I guess it could be one of the other pulleys making the noise as the alternator pulls on the belt?

Nice to see you've found no issues so far Steve. Alexander helped me out a good few times and knows these engines well. If Alexanders happy I would be too

Took the car for a half hour blast yesterday as not driven it anywhere in 3 weeks. Everything seemed fine, had windows down to listen for any boost leaks, nothing unusual there. (Had a split intercooler hose last year so know what leaking boost sounds like). Power seemed normal, turbo defo still boosting, mpg seemed ok considering how I was driving. When I got back I re scanned for codes, no errors reported.
Forgot to mention the car was serviced by MBS at the end of February, so if there were any unusual noises under the bonnet, I’m sure it would’ve been picked up.
Maybe there is nothing wrong and I am worrying about nothing... wouldn’t be the first time

Cheers
Steve

sometimes during servicing, you have to disconnect some sensors and turning ignition on can leave error codes although usually with me not the one you got. possibly code caused by a low battery, some sensor disconnected during a service or part change or an historic code stored in the ECU. Either way you have a happy Vito

Thanks Kev... I have a C class btw

Lol sorry Steve, vast improvement on the Vito dunno where in god I thought you had a Van
Ahh realized now I was posting earlier on another topic and got the two mixed up

Good evening,

Just curious but what was your injector problem?

Kind regards

Maccy

Hi Maccy I basically needed a new set of injectors, problem started with van intermittantly running on three cylinders at times to the point were the injector just gave up one day. There was an over fuelling problem as well with the injector that was faulty towards the end. It filled the DPF.
