Why Is The Audi 1.8T 20V So Good?

[@LcFan96]

there are issues on the 1.8t tho: turbos and headers like to crack, theyre consumables on those engines due to the head being a hot one. oil sludge that can block the oilintake from the pump, so you should be doing your oilchange atleast once a year or every 10k km. sometimes even the head can crack from valve to sparkplug hole, but thats rare. other than that, these cars are getting old so youll be needing to do lots of cooling hose replacement (nearly all on my 99tt bursted by now), some stuck theromstats here and there, some leaking cooling flanges. some leaking valvecovers and oilpans, other than that, if taken good care of they are pretty reliable. also they are huge differences between the 150 and 180hp engines to the 225/240hp engines. the higher power one feature double oil squirters for the pistons, dual intercoolers, a shorter and flipped intake, bigger turbo and bigger injectors. other than that great video, you covered a good amount of infos. much love from germany

As a tech in their hay day only one thing caused sludge. That is a pcv system failure. The valve goes bad (hidden inside a hose) and leaks boost into the crank case vent. Taking all the sludge from the crank case and turbo charging it into the oil pan. This also caused oil leaks. Because you are turbocharging the crank case. This was made doubly worse because owners refused to pay the labors to properly fix the system.

I bought one of these to fit in a polo 6n2, absolutely hated the polo's road feel so its been abandoned since, one day i'll shove it in something else

[@locojambo]

I have a 1.8t agu fully stock with 165,000 miles on her and she still purrs like a cat. Couple of years ago I pulled the threads on the sump plug (2 oil changes per year for last 13 years maybe had something to do with it) so I replaced the sump (along with the oil pump). With the sump off the engine looked as if it was made out of gold. I wish my phone hadn’t died as so I could have took a picture, I’m not kidding you that engine was pristine.

[@heikkipartanen6972]

Audi b6 1.8 tq 163 hp. Reliable and smooth engine.

[@BigSteve_Gaming187]

I've got a 2004 VW Passat Wagon 1.8T with the AWM code. I love 1.8's as I've had a variation in my 91' Escort GT 5-Speed and my Nissan Sentra Type E which was a 4 speed. I change my oil every 3k miles and currently use and love my NGK Iridium Plugs. Even after it sat 4 the entire winter 2 cranks and starts with ease. Very dependable motor that is still whisper quiet with 208k on it.

[@lechkrol4883]

I wonder if u can modify a Honda VTEC cam to run on the intake side. That middle valve would get the VTEC lobe at all times. Just a random thought. But it wouldn't to far off. Also would be cheaper just to upgrade the original cam. But still.

[@haydenadams6606]

That’s actually a good idea, it would all depend on degree of when the cam opens plus valve springs and retainers.

[@ricardorosinha5482]

THE BEST ENGINE!!! I have the agu 150 on my a3 and the APY 210 on my s3, that engine just want always more and it’s inbreakable…

[@paddyodoors2757]

Mine is on 170k miles, 24ish years old and runs a hybrid turbo and 230bhp. Love these engines.

[@KowalDWR]

227 bhp on hybrid too with 194k km mileage. Bfb type

[@Reefer-Rampage69]

I love my 1.8t. The engine is great and so is the car! It’s just always something stupid breaking lmao

[@jakeeames725]

I am currently building a 2004 passat 4 motion with a 5 speed! Got it for free all it needed was a fuel pump. Currently putting kw coil overs and adjustable arms and polybushings can’t wait to drive it

[@2Skills4u]

Enjoying my 1.8t Cupra, mk1 Leon's are the best looking ones with 1.8t imo ;) pushing 221hp atm with 336nm of torque and honestly I think that's enough to satisfy me, coulda went with a cupra R and get 225 stock but...I didn't lol. used to be equal with my mate's Type R when doing rolling pulls now I'm leaving him behind even when giving a lead. Engine head rebuilt in October so 5 months ago and semi-refurbished the gearbox too we'll see how reliable it lasts at 90k miles now. Drove to Belgium from Scotland and back last month which was 2,000 mile round trip no problem. Only issues I had with the car was timing belt got chewed as previous owner never replaced the bolt for the engine mount when he polybushed, they're single use bolts so it snapped when I reversed it and the threaded bit fucked the belt up. Then had Cam position sensor fail on me, £20 and 10 minutes later that was fixed. And finally used to get 2 engine codes due to the decat, that got taken care of when remapping as it would come back if I'd just erase it. Trouble free for now ;)

[@Chingy474]

All personal preference. I will pick my A4 B5 Quattro anyday over any VW, Seat or Skoda.

[@bettersteps]

I once owned a 2001 manual Golf with this engine. I loved that car. Cried for an hour when I decided to sell it for a 2013 manual GTI.

[@dmitrikaljuznoi1323]

The durability numbers of 300k is pretty pesimistic i`d say. I had an a4 b5 with a 1.8t and the milage was 350k (pretty sure the original milage was higher as the car was 25 years old). Reliability was almost perfect even with some mods made

[@3n3ly7m9]

309782 miles or (whateverish 600kms) the stock turbos wastegate broke

[@buddysshop1860]

375k km all original with stage 2 tune beaten on daily 😎

[@hassangooner233]

just got myself an S3 8L with a t3/t4 turbo..love it😍

[@Eduardo_Barbicha]

Esse motor é monstro! É a reencarnação do saudoso motor AP.

[@TheDudeV1]

My dad has a 01' tt, I gotta say, even after 200k kms it rips like new. The things that have worn out are the convertible electric motor and the boot latch. Easily fixed. Had a misfire in one cylinder so we changed the spark plugs and good as new.

[@S.R.Productions]

My first car was a 2001 audi tt coupe. I got it at 225k miles (360k km) and it still runs just as good. I have had to replace some of the plastics for the cooling system, thermostat, and some pcv, but other than that I had nothing major happen, engine wise. I put about 25k miles (~30k km) on it, and slowly restored it to the best of my ability. The only worst part of it was that it could only fit 2 people comfortably, and not haul much as it is a Quattro which had less trunk (boot) space than the fwd. Sadly I plan on selling it as I am going to college and I need something to haul my motorcycles, but it was the greatest car I have ever owned. If I could, I will not sell it as I love the car to much and I would love to pass it on to my children one day as their first car.

[@Edik0704]

Me who has 171k km with the Original Turbo 😳 Edit: To be fair, my wastegate is ratteling, which stops after the engine heated up

[@biggabenne]

your profile pic is your reaction to the turbo

[@NousagiMechanic]

2002 Mk4 AWP here, just finished a full overhaul and K04-022 turbo upgrade. Absolutely love the engine, and to date (241k miles) the car has never left me stranded. As with any other German car, the 1.8t does not take deferred maintenance well. Keep up on consumables and it'll treat you fine.

[@petermeter3942]

Important information: The forged cranksahft is only in the AGU (golf 4 150hp ), BAM (audi s3), Audi TT. The other engines just have cast crankshafts. The cast crankshaft is good for 400hp .... it will hold 500- 600hp but not very long. The best 1.8t is the Agu Block. Its a 06A block it has stronger rods (forged 20mm wrist pin), and no electric vvt, the head has bigger ports (exhaust side). The agu engine is basicly the "strongest" 1.8t and holds up 2 300hp reliable.... with stock internals. If u want more horsepower in these engines, at least disasemble the head an get new exhaust valves (the stock valves can snap off if they are older). Great video 👍👍

[@danielmarshall4587]

Lovely vid cheers, and yes the "TWE-EGH-VALVE-TURBO" as is often said here in the north of the UK, was/is a much loved engine.

[@richardgraham7672]

I've run two 1.8T AJLs up to 385,000km in facelift B5 quattros. One I've sold, the other is still driven daily. I found with both at around 250k the exhaust valve stem seals harden and start allowing oil past. To be expected with a turbo engine as the exhaust valves can get extremely hot, even the sodium filled ones in the 1.8Ts. I've always just kept driving them like this until the oil usage gets to about 1L per 1000km, then I pull the head and inspect - both have made it to 350k before this sort of oil usage. At 350k the cross hatching on the cylinders was still present evenly across all cylinders, so new valve stem steals and back together. One engine I had to replace the valve guides on the intake side as there was a very small amount of axial play present - this is the car I drive daily which has 390,000k and uses no oil between changes. They really are great engines. Fuel efficient, fun to drive and surprisingly pretty cheap to run.

[@gabrielvanya8245]

Just to give a heads up: the internals could actually hold 500hp, but the weak part are the Connecting Rods. It doesn’t matter which engine, they only do about 380Nm, above that and it’s just a matter of time until they bend.

[@matejdedic2599]

I have 1.8t in first gen skoda octavia and it has now almost 400k km with no major issues. Its daily driven, and i love the engine dynamics. Its quite fast considering fact that car weights about 1250kg. Its fun to overtake other cars on autobahn in 200km+ speed :D

[@GabeNydick]

I have an AWV new beetle that I'm going to be building the engine on soon. It's already pretty quick with a tune

[@vr6prodigy]

This was definitely a fun video for me. 1.8t swapping an mk2 or 3 is just a great choice always!

[@dumpstuntin]

Had a 1.8t for 22 years my favorite motor.

[@1988orpheus]

Had an A3 with a chipped 190ish hp and currently a TT Quattro with the 225hp K04. Great little engines, but work better in higher revs. The K04 units also have twin Intercoolers I believe.

[@aaronamarok]

Going on 350,000km on my 1.8T Jetta and it still runs like a champ. Only issues are typical plastic bits going bad.

[@TeamGxx]

Just got an 2010 a3 1.8T, absolutely cracking to drive

[@jaanraas]

I bought 1.8T B6 as my first car. Was driven little over 400tkm. Havn't had any problems with it so far and i use it as a daily drive.

[@mk2daz]

That was a nice surprise to see my Mk2 Scirocco at 4:54 ! Nice video

[@1245rs3]

I miss mine, had a 2001 aww and awp. I did a GT28RS and it was bullet proof.. Great motor

[@drifthero1176]

Finally a 1.8t vid. Now I can annoy my friends with this 😂

[@YSvet27]

Got 260k miles out of my '01 A4. Stock daily driver up till 2019. Upgraded to an A7, but still have a soft spot for these cars :)

[@twiceone001]

Thanx VisioRacer for the good specificated video. I own a one A3 1.8T AGU.

[@benjones1917]

I love the 1.8t in my Mk1 Octavia VRS. It's starting to become a rare car now, so I need to put some real time and money into bringing it back up to scratch

[@angelothabo4107]

I love this guys video he knows alot about audi and VW

[@tzsteve33]

Had a 2001 A4 quattro b6 (AVJ) engine for almost 6 years, was remapped to 200bhp. Great engine hampered by crap vacuum system. As was mentioned oil sludge is the main route to failure with these so oil changes and using the larger oil filter is essential. Think I went through about 5 coil packs in my 6 years of ownership. Also had a crank hall effect sensor fail. Went through 2 water pumps also but didn't mind that as it was due a t belt anyhow. Eventually changed the car for a EA888 A4. Wish I could say the same for that engine.

[@danieler8410]

I have a 1999 Audi TT, 179hp, beautiful engine, did 15k km in one year and no issued even if it had 25 years

[@Caligrapher88]

These engines have proved extremely durable! Good job VW

[@joshyboi8]

225 BAM owner right here! I think a couple of things you mentioned on here are incorrect though I’ve been told by many 1.8t specialists that in fact nothing in the engine was forged

[@VisioRacer]

Yeah, some commenters corrected me yet
