How To : TFSI TIMING BELT and CHAIN

Thank you so much for the simple timing explanation, the forums are awash with cryptic and incorrect information, and you're extremely straightforward!

[@DecimalTenths]

Here to say thank you! Did the cam chain on my edition 30, made marks on the cam’s and cradle before I took it off but for some reason was half a tooth out when I put it all back together, still had it’s full power but revs would hang, idle high etc etc. Attempted to sort it a couple of times since but I never got it right, then I came across your tutorial for the chain. Been about a month now since I’ve done it, and touch wood, it seems to be all okay. Counting and marking the chain links away from the brass link was a massive help. Had to subscribe because of it, and will check out more of your videos.

Very good information especially using VCDS. One thing that I did see is you didn't replace the motor mount bolts. On the Audi with the stretch bolts this is a necessity. Is the VW different?

No they are the same, so "should" be replaced. I didn't on this one admittedly as first of all it's mine.., and secondly I knew i had to pull them off again a week later as the engine came out to fix a snapped stud

[@DecimalTenths]

Cheers dude. That is the duty cycle on the VVT (N205) solenoid. Essentially how hard it is working. It will change with revs to make the actual cam position match the specified. Around 6% at idle is perfect.

[@manup2008]

Great video, given me the confidence to attempt it myself. Should I lubricate the chain and tensioner with fresh engine oil when assembling? And maybe put a few drops on the camshaft too?

It's only done 1,500 miles since the rebuild but at least I have some idea on how to monitor it now so will just do a quick check once a month? Today it developed a suspected air leak after the idle went crazy, so checked out the throttle body on VCDS plus the sensor both seemed ok and working correctly, so we had the smoke tester out with the UV glasses and torch to finally locate a burst pipe right under the manifold 🤦‍♂️ These videos on KZbin actually help a novice with diagnosing problems rather than running to the garage for everything 💪

[@old.yfzr6280]

Huge question tho before I do this. The crank tdc mark is spot on the cam is 1/8th off just like a sliver.. it was running an driving before the cam chain tensioner just broke so I figured Id do it all at once. Which one should I make sure is spot on since when the cam is at the tdc marks the crank is a little before it… when crank is at tdc arrow the cam is a little past it..

[@DecimalTenths]

The cam marking is on plastic so could be slightly out. Confirm it by measuring tdc down the no.1 spark plug hole. There is a way of doing the belt by counting teeth also.

It can sometimes be a bit tricky due to the mount and the turbo water return line that runs down there. Just got to be gentle when removing. If it comes out no problem, then it's generally been trimmed by the previous guy who changed the belt. Early TFSIs came with 1 piece covers which are appallingly bad to remove 🙈

[@chriswebb8587]

Great Video! I will always mark the belt like you do from now on. Ok, here's my issue after replacing the timing belt on my 2007 Audi 2.0tfsi BWT. Timing belt changed, car up and running. Now I plug in VCDS to check cam chain and in timing block 091 getting 6.3 / 28.0 and in block 093 I'm getting +5kw. I was expecting a -4 or -5kw since I just rolled over 200,000 mi (320,000 km). So I pulled off time cover, checked the marks on cam and crank pulley and they look correct. pulled spark plug 1 and double checked for TDC and that looks good. Am I correct that +5kw means the timing is advance? I've been hearing what I think is a bit of cam chain slap on startup, so I'm getting parts together to do the work and when I checked VCDS I got the +5kw. Also did the cam pulley seal while I was in there. Could I have put this together wrong or have the belt 1 tooth off? Have you seen this before?

[@DecimalTenths]

Yeah we see positive (advanced) figures often. Generally not as big as 5kw, but its nothing to be worried about. The timing sounds correct from your figures. Remember the phase position is merely a measurement of error (normal to have some), and can indicate a tolerance in the timing components as well as a fault. Best bet is to replace the chain, tensioner etc with genuine bits and see where it is then.if it's still out, then at least you have peace of mind that there's no danger of it snapping. Then road logging would confirm the VVTs ability to adjust cam timing inline with specified.

[@chriswebb8587]

@@DecimalTenths What blocks can I use in vcds to check the n205 and could that be the problem causing the +5kw? and would low oil volume or pressure create a +5kw? And if it's not too much to ask, what is the road logging procedure? Thanks for the quick response!

[@Vaughany4128]

Right I've done my chain and was still reading 44°kw actual! Couldn't get bank 1 reading at all block 093. Found my timing belt side to be 2 teeth out backwards while the crank was TDC! Sorted that out and now my actual reading on 091 is 27.5/28°kw. Now getting reading on phase bank 1 and that's sitting at +3.0kw is this normal or something still off? Car runs so much better like!

[@DecimalTenths]

Timing sounds like it's correct now. Check block 091-2 and see what the duty cycle is. Should be ~6% at idle. Did you do the oil control rings? Might be a sticky variator too. You could check the n205 solenoid, cam position sensor, etc... Then you could just drive it, be happy you've replaced what you need to and enjoy it safe in the knowledge that the chain is fine.

Hi @DecimalTenths I changed my chain and tensioner last weekend (INA set) my readings before were -3/-4 after changing the set now it is on -2. BTW I used your video as a guide. visually when everything was mounted the chain looked exactly like yours. I was hoping to get to 0. However, when doing a cold start I can still hear some very short chain rattle for a tiny bit of a second. is the tensioner maybe faulty even if new? best regards

[@DecimalTenths]

Hi there, -2 is an OK measurement. It's common on the non oem kits like INA to have some tolerance. The tensioner is oil fed so drop your sump and clean out your pickup to ensure it gets good flow from startup.

[@JosipZelenika-pb4zc]

​@@DecimalTenths after hearing some minor rattling on cold starts, I decided to take the new set off after only 200kms. What I noticed is that the chain became really "stiff" and if it seized somehow. Now I don't know what to do. I ordered another set, maybe the chain was faulty or maybe there is another problem with oil preassure. I installed a 1.8t oilpump and a bolt on oil Filter housing from a fsi first gen. Only checked the oil preassure once before starting the car since IT was a complete rebuild, the oil preassure was building up to around 2.5 bar at starting (without ignition)

[@bobg1901]

Hello mate, my son did his servicing for a 08 Reg Golf TSI but after few days he found the engine warning light on. I connect by OBD an cleared the fault. But now the engine is not starting and the AA said it's possibly the timing belt as it's not starting at all. I doubt it as everything was perfectly fine until I cleared the fault. Do you think it need the crankshaft sensor changing. There is no knocking sound when turning the engine.

[@DecimalTenths]

Hi there, This is the type of fault in which I could diagnose pretty quickly if the car was in front of me. You can check the output of the crank sensor in a decent diagnostic tool which will give you the answer. I wouldnt recommend guessing and firing parts at it. Best to book in here or somewhere local to you who can diagnose for you

[@CR15PY1]

No they can be stuck sometimes, and we've even seen them jammed up with silicone from previous removals too. It will come out with the 3 bolts removed.

How I got here, was driving the car like a normal person, 75mph, all of a sudden a loud claddering noise started, stopped the engine, everything looked ok, started it again and same thing. got the car towed home. did some research and thought the timing chain tensioner gave out. Ordererd all the parts to do the timing chain and timing belt. Today i completed the repairs. went to cycle the timingbelt by hand, and stilling getting the same results, loud bang noise. Noticed that both cams are not spinning at the same time at times. Is it possible that outer camshaft is broken????? Any thoughts???? thank you for your time

[@DecimalTenths]

Just a stab in the dark based on what you've said I'd pull the rocker and check cam to cam timing. There is timing marks as per the video so you can cycle the engine, check the marks and go from there bad on what you find.

Hi, great tutorial video! I recently bought a GTI and checked the engine group 93 values - it looks fine (-1.0KW). I didnt check group 91 tho. What does that mean for the timing chain and timing belt? Are they both in good condition or I can only be sure about the chain? I am a little bit worried about the cover next to the fuel pump (yours has white "GTD" writing on it) mine is very dark and oily - what could that possibly mean? Previous owner stated he did some work on timing 13k miles ago.

Thx for sharing

[@codegreen5213]

This was really useful thanks! My S3 had HPFP failure and I've replaced: Cam chain cover (The bore for the follower was damaged), Hpfp for a new unit and replaced the HPFP internals and the piston was damaged (They're uprated as car is stage 2+) using my cheap reader I can see that my fuel rail pressure can't keep up at full throttle, if I put foot down and wind to maximum boost the fuel rail pressure drops down to almost zero, the engine floods and won't start until it's been sat for 20 mins. My intake cam lobe had some wear following the failure, I cleaned it up with 2000 grit and metal polish then changed the oil and filter.. I'm thinking that I need to replace my intake cam due to lobe wear. Is the process for replacing the intake cam pretty much what you showed in this video plus just swapping the cam over? There's nothing needs re-shimming if I'm changing cams? Thank you! Much appreciated

[@DecimalTenths]

Hi pal, Sounds like you've had a mare...🙈. To remove the inlet cam you will have to remove the upper cam cap/cradle which also holds down the exhaust cam. This can be done leaving the exhaust cam timed up via the belt, but just be careful if you're not removing the belt, to ensure it doesn't come off. Also when refitting the cradle make sure you're careful when torturing up. Not a terrible job to be honest. The ideal way is obviously to unhook the timing belt and relieve the pressure from the exhaust side.

[@codegreen5213]

@@DecimalTenths I really have! Been off the road 3 weeks so far and cannot find any garage that will work on it without charging nearly 2k! Hence why I'm looking myself 🤦‍♂️ Thanks for that, doesn't sound too bad, the car has also developed a leak from the hpfp since i swapped that out 🤣 If the thing drives again it'll be a miracle!

[@chrilleman16]

so i did mine and it all seems fine, no weird sounds or anything, sounds amazing on idle and revs just fine, but ive noticed tiny small backfires when the car is cold and i rev it, and i honestly dont think ive had that before. as soon as the cars gain temp the pops stop. could the timing be off?, i think i need to get my self one of those readers

[@DecimalTenths]

It is possible that your timing is out. Best to check it and know for sure 👍

[@Flishlakv2]

I appreciate the content nick do you think you could provide a part number for the vvti oil control rings as tps have no idea what I’m talking about much appreciated

[@Flishlakv2]

any update for the part number? :)

[@jpra64]

So the cam timing delay (-4) comes from worn out timing chain tensioner? would this be the same case for the 1.8t engines? On a cold engine I can lift up on my hydraulic tensioner and cam timing 1 will be -2-3 but driving it usually finds it way to -3.8-4 but the belt is tight would this be chain tensioner or chain?

[@DecimalTenths]

It can come from any part of the system that wears and allows a bit of slop. The principle is similar on the 1.8t engine, but generally not a problem as long as it is all timed up properly. Best to check vvt actuation by logging on an 1.8t to see if there's an issue.

[@jpra64]

@@DecimalTenths I'm going to go to a manual timing belt tensioner cause I dont want a bad hydraulic tensioner to take me out, just wasnt sure if I should throw a new chain chain tensioner at it as well which I probably will, my timing marks line up but does -4 mean the cam timing is -4 degrees out? Like if I had an adjustable cam gear and advanced it +4 it would be zero?

[@BijahD]

Outstanding

[@chazdunn9166]

My phase position on group 93 is at -20. Group 91 shows within 1.5 degree of spec vs actual. Timing chain kit done 50k ago, no rattle from there at all either. Cambelt kit only 1 year ago. No idea how it's that far out and not sure where to investigate. Occasional blips in engine feel at low RPMS, but starts quickly, pulls great and no codes besides p0016 002. Any ideas?

[@DecimalTenths]

Definately a timing error code there. Got to go through it all - check belt timing, check chain timing (might as well replace if going in that deep), check the variator pulley isn't seized, check the gauze on the back of the tensioner is intact, assemble and log vvt position vs spec.

[@NolTee2]

Quick question @DecimalTenths I changed the chain & tensioner but I'm not happy with how it idles. So I re did it & it's still not right. Before I do it again.. What do you think of this. When I do a scan this is how it reads Block 91 Engine speed 720/760 Cam adjustment intake B1 74/76% At idle. It has a new vvt. So it's not that. What could be causing such high readings. It's doin my nut in. Cam adjustment B1 specified 24 kw CAM adjustment actual 24/25kw Block 93 Engine speed 720/760 Engine load 13.5/14 (yours is 16.5%) Phase position B1 is -1. That's at full temperature too Any help please It's a 2005 axx engine

[@martinnrhave6832]

My "Cam. Adjustment intake bank 1" in group 91 is 43,1% at idle. Any ideas as to what could be the probem? Also the "Phase position bank 1 intake" in group 93 is -9 degrees. Just the chain or also the timing belt?

[@DecimalTenths]

Check them both. Easiest to check the belt end though. Sounds like there's a big error there though

[@martinnrhave6832]

​@@DecimalTenthsI ordered both the chain and the belt. Might as well change them. Do you think this will solve the cam adjustment or just the phase position?

[@07frbaiz]

Great video, do you have any videos doing a timing chain on VW golf 5 FSI engine?

[@DecimalTenths]

Cheers, sorry no we don't see many of them 😬

[@NolTee2]

Anyone know a scan tool to recommend besides VCDS that can do measured blocks that doesn't cost a fortune. Something that can do more than just VAG group cars.

[@TheLewiscroker]

Just wondering if you could help explain my readings please. Upon initial testing block 91 had 4.0 difference and block 93 was at 0. After a 50% throttle rev and returning to idle block 91 was only 0.5 different and but block 93 was reading +3

[@DecimalTenths]

Would need more info from logging to see what was happening dude.

[@TheLewiscroker]

@@DecimalTenths thanks for getting back. May take it for a little drive tomorrow although I do have a cam belt kit along with cam chain and cam follower arriving this week any how

[@MrR4H33M]

Which is the right kit to buy as many part shops just say it’s a 2 item part and some say it’s got more than 2 things etc. I have an 05 plate AXX engine.

[@pravvvy4756]

Hello, I changed cam chain But now the car doesn't pull. At idle I now see 28 KW Cam Adjustment Intake B1 (spec) and 55.5-57KW Cam Adjustment Intake B1 (actual). So nearly double… With the old parts, these used to match (28 and 27.5) I also don't get a value for phase position in group 093 anymore. It's just blank, can you help me?

[@DecimalTenths]

Yes your timing is very wrong. Time to strip it down and redo it.

[@pravvvy4756]

Thanks! Could something have happened if I drove 7km like that?

[@Roman-.]

I assume, it is the same engine like in octavia II rs preface is that so? BWA 147kw

[@DecimalTenths]

YES BWA motor 👍

[@PappiH]

On a chain that's all black links, I suppose I just mark one of the links and count 18-19 from there? It shouldn't matter, right?

[@DecimalTenths]

No doesn't matter, just count it right 👍👍

[@chaddavis4901]

Followed this video for a cam chain, tensioner and VVT replacement today, phase position was around +6kw before and is now sitting at +10kw!! I have stripped it down twice and same reading!! Any ideas? Thanks

[@DecimalTenths]

I would log the car on a pull, for block 091-2/3 req vs actual. If they agree with no fault codes then its doing its job. You could leave it with the peace of mind that you hVe replaced the chain and tensioner. If you wanted to dig further then check the oil control rings, n205 vvt solenoid and cam position sensor.
