Intake Manifold Failure Code P201400

[topher]

the sensor is 100% available as a separate part and takes 5 minutes to fit. 06K 907 386 D £51.49 +VAT. I've replaced around 10 of them now on various gen3 TSI engines.

FFS I did ask that question before he ordered the whole unit. He said it had to be replaced as a whole. Is that the only sensor on the unit ?

Sounds like your VW specialist is misinformed. If you'd had this done at a dealership and they'd made you get the whole manifold, you'd have a strong case for complaint with a view to large partial refund.

It is the only sensor yes, on the opposite side of the manifold to the flap actuation unit, pop your engine cover off you'll see it sitting just behind the oil filter. There is a solenoid that feeds the flap actuator but the fault code you posted is for the position sensor.

On the Mk6 engine you would generally replace the entire manifold for that fault code, since the sensor on those is a potentiometer which mis-reads when the keyway the sensor sits in begins to wear, so the manifold runners turn without turning the sensor. Different setup on the Mk7 looks more like a hall effect sensor.

Just off the phone to my mechanic he said he was aware of that switch been stand alone. He explained that the car was also giving misfire codes in cylinder 2 and controlled cylinder shut off codes. He swapped coils around but codes stayed. He’s adamant that the entire intake needed to be changed. Think I’ll just have to grin and bear it.

So did the misfire and shutoff codes cease after fitting the whole manifold?

If you go back and read what you said originally, which presumably is what he told you originally.... he said it needed replacing because it only comes as one part.

Now he's saying that there were other problems that meant it needed the whole manifold....

Sounds like back peddling to me...

It's a real shame if it didn't need the whole manifold changing but you're right, best action is to move on. Is this garage normally one you'd trust? If so it is worth maintaining a good relationship unless something else goes amiss. Enjoy your car

Thanks Watts. Wise words indeed. Yes he’s a personal friend for the last 20 years and I fully trust him as he has always worked on our family’s Veedubs. Will move on. I must admit though car does feel like it has a bit more pep in its step and seems spot on. No CEL light so overall I’m happy ! Case closed. Hopefully this thread will help others to not male the same mistake if they get the same fault. Thanks for the help guys.
