Well looks like I jinxed myself telling everyone how reliable my early production Mk7 GTi is. Check engine light came on last week , car driving and idling fine. Ran VCDS diagnostic and got code P201400. “Intake manifold damper sensor electrical fault”. Brought it to my local VW specialist and he said it’s a common failure part. Made of plastic with all the sensors and flapper actuator attached to the one part. He said it’s the sensor has failed but he has to replace the whole intake manifold. Price of part is €550 and I’m guessing a good few hours labour as there’s a lot of ripping involved. Will have a check for carbon buildup but I know it’s not an issue here due to the multi port injection that the US cars don’t get. The new manifold is the third revision of the part since 2013, supposedly it’s failed so much on US cars that they extended the warranty on the part, not for European cars tho. Sorry for the long post but just wondering has anyone else had to get their intake manifold replaced. ??

How many miles has your car done?
-
92,000km so 57k miles approx

Seems like any repair at the minute is called a common fault on these. I haven't heard of anyone on here needing one of these.

He says its a common fault in the USA... their GTI's use a different engine don't they? In fact a lot of their GTI's build is quite different, not least of which, its not built in Germany.

Built in Mexico or somewhere isn't it. Be interesting to see if any of these faults occur in the UK now that dual port has gone and we are now like the US with single port?

Carson's early MK7 GTI will be a dual port example though.
I wonder if that manifold is an "exchange" part to offset the hefty replacement cost for such a small part of it overall failing.

yes but new ones are single port so it'll be interesting to see if this issue crops up in the UK now.

I had this fault come up on a previous MK6 Gti I owned- I had agreed to trade it for my MK7 so I had the warning light turned off and managed to get it to stop off long enough to get rid of it.
It was the same fault with the sensor in the manifold and the cure was to change the manifold.

Picked up the car this evening. problem sorted. €700 out of pocket tho :sick:
As said above it’s quite common in the single port Mexican built engines but rare in the multi port engines. He did say the valves were spotless with no carbon buildup. showed me the old part and said the new part was definitely made with a different composite and that the sensors looked beefier along with a stronger flapper mechanism.
-
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 :smiley:

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. :smiley:
