Hi all,

 

Finally getting somewhere with my weird idling problem.  Had a local lad look at it with his VCDS and it had only one error on it - the popular P2015.

 

Looks like a new IM is needed.  I take it the flap motor and sensor can't simply be replaced separately? I definitely need the whole thing?

 

Also, one thing that confuses me is the date of the error.  It's dated Feb 2010.  Is the date wrong or is it the first time it was logged? Or perhaps my car simply does not actually have this error currently and I'm back to square one?

I would clear the code and see if it comes back. It is showing as intermittent.

Thanks, it has been cleared, however I have not yet seen an engine light come on yet.  I'm going to be stripping it all down to clean carbon deposits so I might as well degunk the TB also whilst it's all apart.

 

It's just annoying because now I'm potentially looking at removing the IM twice, meaning I need to replace gaskets and seals an extra time :(

Any more thoughts, folks?

Can't you just actuate the motor whilst measuring the output of the position sensor - that will tell you if the actuator is moving its full travel. If it is then it isn't stuck completely.

If you're going to remove the manifold to clean the backs of the valve then you might as well replace the manifold whilst you're doing it. This will cure the error at the same time.

It's a big "may as well" at £300 for a part though :(

He did this I believe, so the motor and sensor haven't failed.  I wonder if it's worth giving it a thorough clean.

It would be a bit of a waste of time and money (new injector seals again) if you had to remove the manifold again a few weeks after removing it to clean the valves. My point was to bite the bullet and do it all in one go for the peace for mind.

True, but it's not like the IM is a serviceable part.  It shouldn't need replacing. I've just booked the car in for service and MOT, and have asked them to check for p2015. If it's back, I'll ask them to clean the flap there. If still no good, I'll see about ordering a new IM.

 

Can I double check something please - is P2015 referring to inlet flap motor, or swirl flap motor?

Edited 12 October, 201510 yr by planehazza

P2015 is for the inlet flap motor, flaps that stick or the sensor.

 

If you're going to take off the IM and don't want to splash out £300 on a new one, give it a good degrease and fit a new sensor on the end.  I bought a new IM but found the old one was just crudded up AND the sensor was faulty.  I also checked out the actuator but that was fine. Ebay sell an OEM replacement sensor but you can only get at it if you first remove the IM.  A 5 minute job on top of the hours to do the IM and decoking. No guarantees but worth a punt?

What exactly does it do?

Limits the arm over extending in the actuator

Does it help to get rid the code?

Surely then this is just going to bind the motor causing earlier failure? Or does the ECU retrain the flap limits?

Apparently it's a long term solution according to these guys

Yup that's the whole point

That's on a diesel though.  I really don't like the idea of mechanically limiting something when the motor is still trying to drive it further.  May cure the P2015, but surely that motor is going to fail eventually. Plus, hiding the P2015 is not really a cure in my book. Does this arm not just mechanically limit the throttle to 98% (for example) instead of 100%?

I've just been told by a dealer that the inlet manifold for my TSI is £320 inc postage.  What part number applies to the 2L TSI?

 

Not too impressed either as they're refusing to give me a part number, and are instead insisting "it is the right part"...

You didn't say you had a petrol .........

Sorry, thought I did. I've had a few threads about my car issue so they're all starting to blur.

 

Mods, would you mind adding to my OP that it's a 2.0L TSI Petrol.

No worries

Well fitted the part to my diesel today and it's worked a treat........so far

Oh and as for limiting the arm movement to 98% I think it's more a case of limiting it at 100% not 105% (for example)

Ah OK I get you.  So it's not any more mechanically limited, it just stops the arm driving further than it should normally? Is it not still going to be putting strain on the motor though?

Yup that's it, as for a strain on the motor isn't over extending going to put a strain ?

Yeah but instead of straining against the side of the TB, the arm is now just going to be straining against this metal block instead surely?
