Had the same issue, if you watch your vid closely you can actually see the flapper arm is actually moving in the bush/housing in the Turbo as well, this was the same issue I had. I was going to do the same thing you did, but i ended up machining out the old bush making a new one and modifing the actuator so it was adjustable (like older turbo actuators with a thread on the rod and threaded eyelet that fits onto the flapper). Anyway Great to see someone is actually repairing (err modifying) these turbos for such a simple issue rather then just replacing the whole thing.
Got the dreaded P0299 code and it was the same problem on my VW TSI engine. Had the shop replace the turbo. I’ve seen this fix before, but you show the mishaps while getting the gate to seal properly. Nice video, Nap.
Love your vids! Got a p2293 on my simple reader and U111300, P008800, P125000 on a more advanced reader. The only thing I feel differently with the car is like 3gear att 2200-2400 on full gas it tens to not bog but like studder for like a milliseconds. Any idé why?
Damn what a great informative video! Best one every to fix this turbo issue! Thank you for sharing brah ! How good is this fix if you nail it perfectly right ?
You can just simply tweak the wastegate solenoid mount enough to get preload back on the flap. It can be done from the engine bay topside in about ten minutes.
my 2010 a4 has a misfire under boost only, it kind of jerks around 3k rpm. it had an underboost code that has since been cleared. i didnt know if maybe the pcv valve/oil separator could cause an underboost condition?
My 08 a4 spits oil out of the exhaust and scanned the computer after noticing lack of power had a p0299 underboost. Then code went away after driving some and came back later. Car makes some boost but I don’t think since i got the car it was ever making boost right. My turbo doesn’t sound as loud spooling up as other stock ones. I’m going to replace the pcv valve because of rough idle when opening oil fil cap. I’m just getting into turbo cars and this is my first one. I’m most likely going to replace the turbo with an oem one when the budget is right for me but this is more of a project daily and I’m trying to squeeze some more power out of this turbo before i replace it. Any Ideas?
Passat 1.8t here. Under boost code. But the boost gauge shows it reaches 10psi, which is the factory upper limit. Is it possible to get 10psi with bad wastegate linkage?
I have the same thing on my VW Tiguan ! But can't get to it with the Motor in it , Same Code , Low Boost. Check light on , it will clear but comes right back on.
@@tubbycustard8866 thanks, yep so far my car is still running well. I noticed over the past year it burned a quart of oil but I barely drove it over last 12 months and all super short distances. Will need to drive it more and see if I have a oil burning problem now from all the short drives.
I see a solution but I'm curious : What would cause this problem actually? What would make that waste gate not to seal properly? Something is worn out, bent, what else?
Could you do a video on turbo starting to fail or still drives me but on its way out the door in the near future? ( if there’s particular sounds associated with it )
Not really a sound until it’s too far gone but people like turbo stuff and I’ve have some turbo failures that I’ve experienced in my own cars as well as fixing customer cars so ya I’ll do one on that topic
The sleeve on the flapped arm that goes thru the cast was moving around on my old turbo. making the flap move up and down making it not close. I fixed it by sticking a spring pin pressed into that hole after drilling it out a tiny bit. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-G6B5lWA6Ces.html
If you pull the exhaust and cat off completely you might have enough room to swing a hammer but just with just the cat unbolted there’s really not much room to do anything but verify that the slop in the wastegate is there
There actually a much better way to repair this. You can just by a new wastegate flapper kit provided the impeller cartridge and bearings are still good. Food for thought.. there is no need to replace the turbo. Just another money making scheme by greedy mechanics that prey on ignorant people. I rate if someone is mechanically inclined and have some tools, could put this repair off. Just my two cents! Not saying you are one of those greedy mechanics, love your videos!
