Hi does anyone Have a photo of a 2.0L 16V GTI Engine showing whats, what, throttle body, MAF thingy etc
Thanks

Cheers but looks completly different, DOHC stamped on the manifold etc.
I'll have a closer look
thanks again

that photo in link is the 8v engine not 16v
16v looks like this

what info you after mate? :smiley:

That's the one Pal. having idiling problems so was going to clean the throttle body and MAF as mentioned in a few of the threads, also check the oil pipes etc , just bought the haynes manual doesnt really tell me what i want to know

Hope that helps.....
Throttle body is just where the black plastic inlet pipe meets the manifold, there is no maf on a 16v engine, just a map sensor which is located in the ecu and works via that blue vac pipe that runs from the top of the manifold to the ecu.
That black square box at the bottom of the pic is the pcv valve which is part of the engine breather system....hope that helps. :smiley:

Thanks thats great, i'll have a look at the weekend.

Looking the picture, the small bore blue pipe on the back of the manifold, i've (the garage) had to disconnet it to get the car to run, if i reconnect the car stalls, any ideas?????
-
That blue pipe that runs from the back of the manifold is for the map sensor in the ecu, if disconnected or damaged it should/would cause running issues/ stalling, the map sensor calculates the amount of air drawn into the engine at any given time which allows the ecu to dump in the correct amount of fuel.

the blue pipe in the picture is the vacuum pipe for the ECU map sensor
if this is disconnected then engine will run rough
-
But if it's reconnection the enginne stalls, could it be a split hose or an electronic problem ecu??

The old rubber vac lines degrade over time and so should be replaced, if you can get some 3mm ID silicone stuff as this doesn't collapse under heat.

Cheers fellas will go and buy some and give it a try
Thanks again

Where you based mate..?
Go to halfourds and buy some carb cleaner, clean out the throttle body and the pcv (black square box aswell as the breather pipes.
Also aswell as replacing the vac line to the ecu, also do the other little ones....the one under the pcv valve and the one under the manifold ontop of the head, its the fpr one.
Also try cleaning out your idle stabilization valve which is under the black plastic tray that holds the leads...spray some carb cleaner through it and if you look at one end you will see that you can attach
an allen key which if you turn /wiggle it a few times helps to loosen it up.

Based in Warrington.
Can you do me one more favour so its clear, the Throttle body is connected to the manifold, looking at the photo its between the manifold and the air filter, just to the left of the blue hose,
Is it difficult to clean? does it have to be removed and put on a bench?

yes mate the throttle body is just to the left of the blue pipe, between manifold and air filter...
It's best if you remove to clean so you can clean the back properly :smiley:

It can be cleaned in situ but as gaz says if you remove it then you will be able to give it a more through clean.
Easy to remove, just 4 allen key bolts and the throttle cable just unclips...if you do remove have a new gasket to hand as the old one often rips when you remove the TB.
Personally i just cleaned it best i could while still attached to the manifold.
