If you got 250K plus on your TDI Check your intake, it may need to be cleaned!!!! This is one off of a 2000 TDI with 355K on it

That is brutal! I checked mine when it had about 280,000 and it wasn't nearly that bad. There was maybe 1/16" buildup in it. You certainly have your work cut out for you there. :o

The more the merrier :D

340,000 on my wifes 2000 TDI NB has never needed to be cleaned.

You really need to drive them hard to clean out that gunk on a regular basis, or adjust the EGR duration. My car had that before I bought it, and it was cleaned out. EGR adaptation was done, and it's only got oil on the intake after 120K.
I would imagine your turbo is next. The vanes coke up too and will stick causing over or under boost.
Last one of these I did, I tried the propane torch + air hose trick. Man, it's slick at tits and hilarious to watch. It's like a flamethrower! Much easier than trying to clean it through conventional means, and it doesn't do any damage to the intake. Though, the one I did had the EGR that came off. I'm not so sure I'd try in on an AHU or 1Z with the EGR that's part of the intake manifold.

mr bently says tdi intakes are usable as long as the opening is larger than a dime :o

intake PORTS**
not the manifold inlet..
-
if the intake itself is the size of a dime the car is always in limp mode and has NO BALLS

yup..

I am always amazed when I see this much carbon and resins.
Apparently this car was driving until it was taken apart.
EGR is evil.

Theres 2 ways to clean the ports. One at a time or pull the cam. I did the latter because i was already in there doing a belt. Anyways if you do it with the cam in, ya gotta make sure that valve is closed! Then bust out the PROPANE torch. Not an acetylene torch. Burn em out and pick away with screwdrivers and brushes and vacuums and air pressure. If you heat it and blow it out be careful of cinders burning you.
ask me how i know. I cheated, i put in a solid copper egr gasket. Then i cut out a nice little piece of tape for the cel. Stupid computers get it rechipped but i was cheap. Best tdi i had was a M haha no clogging intake crap.
Subject car was a 98 with like 120k and i couldnt even get my thumb in the main part of the intake. Maybe thats y it hunted and surged at wot over 3k. Ya think?

oven cleaner works great to remove the buildup.

best ive found was heated organic parts cleaner... let it sit close to a boil.. shake it round.. stuff falls off... no damage to egr rubber so on..
dealers no clean.. my local one tells owner turbo bad.. so they sell for cheap to me.. i clean intake and run like new... what you get for going to dealer... i even asked bout intake 1st.. guy arued w/me that dealer smarter.. so gave him his clams.. built car.. was such a nice car too.. rip.. passat unicorn (price paid/fixed did not exist then.. and still no one sells any tdi at it) will live on though.. just unsure if i selling conversion or using still..
-
Just some advice for those who use oven cleaner on aluminum parts. Oven cleaner contains Lye or caustic soda, same difference. Don't let it sit over night cause it WILL eat away at the metal. I left an aluminum part in a hot tank with Lye & the next day found a skeleton of the part I put in. Use gloves & glasses, too. It's really nasty stuff. I use a vat of the stuff to clean my 2 stroke pipes down to metal & it works awesome.

The wifes car was so anemic you could barely get up to speed. At first I thought it was the maf sensor but sure enough it was the intake. It was worse than catlin's picture yet it still started and idled perfectly. Luckily the intake ports weren't that bad. I now keep a clean intake on hand to reduce the time it takes to do the job.

ive alawy thought a online shop should core them for more then new price and sell cleaned ones for profit... a vibrating hot tank... throw in.. when removed clean.. the issue is the core... takes my guy 3 days of swooshing the manni in the liquid every few hr when its warm... nice steamy like washing dishes.. some organic cleaner.. no damage to egr.. aluminum pretty.. and no scraping.. he has clean on shelf.. but kinda word of mouth due to core..
hows he know you shipping one back or that say egr rubber not damaged.. some have this.. makes cleaning this way best.. but to have clean one to bolt in place at time of job.. sweet..
