The 5 cylinders, at least the originals, only got tension from the cam spacing, that's all. The 3 lobed thing on the left is the High Pressure Fuel Pump cam lobe, the right is the Variable Valve mechanism.  5 Cylinder cam chain.

As a fellow tall person, you'll find door card armrests are always too far forward once the seat's pushed back. Every single car is like this. Coupes and suvs are usually fine in this regard.

Yeah after a bit more search seems that BPG was used through 2005 CY production. It seems like the differences are in state of tune/ emissions and possibly compression ratio, but there are some other differences between the BPG and BPY. Unclear what they really are.

RIP old CTS:  Miserable splicing job with no slack in the engine bay. Got the new one installed though and... fired right up, immediately, zero hesitation. Feels good. Of course, five minutes later, there was a 'pop' and a bunch of steam -- new CTS popped right out. That's what I get for cheaping out, I guess... re-ordered the real OEM one from ECS + another retaining clip and will try to get it buttoned up this weekend so I can move on to oil changes and other poo poo. There are some conflicting DIYs on B7 A4 coolant system flush / bleeding... any tips? I want to drain the fucker and then refill with new, properly mixed distilled water and G13, and try to burp it clean as much as I can. My theory-crafting... it was corroded just enough that the thermistor was reporting back ~90 C to the ECU (confirmed via VAG-COM), which was not enough to trigger an implausible value fault. Personally, I think this was a failure of imagination by some systems engineer somewhere working the fault mode, but it was also 2006 and the ECU proper in that architecture is KL15, not KL30. So, it would never have the state knowledge to see a cold ambient temp, time since last engine last on, and current coolant temperature and make the logical conclusion that CTS is hosed. Removing CTS, coolant temp reports -40 C, triggers DTC for signal too high, and fan ran at maximum until I cleared the fault. I assume if I shorted to chassis, it would be too low (probably a pull-up resistor on the input line to the ADC). So... with a value of 90 C coming in, the ECU kept trying to start the engine at a point in the cals that was probably stoichiometrically very, very broken, but worked occasionally.

Audi introduced camshaft chain tensioners to adjust valve timing in later half of 90's. It improved engine power and fuel efficiency. Usually the tensioners work well if you change your oil. My A6 from 1999 has original ones, so does my S8 from 2001. 334tkm and 236tkm. The chain only was more realiable but not as efficient. The only problem really is that the tensioners nowdays are 1000€ each and you need two for a V engine. So... Uh.. yep. Bad news if they need replacement. Sometimes I get easy and cheap repairs with my S8. Piece of ice broke the brake pad sensor, also Webasto didn't work. Webasto's exhaust was frozen and fixing the brake pad cable was easy, only 0,6 hours of work (43€). Thanks.

I'm hoping my neglect of oil change is saved by the engine still being under the interval in terms of mileage and only over in terms of time. Curious to see how the Liqui-Moly snake oil stuff works out.

How long should a clutch last in a mk5 GTI? Going on 140k kms (85k miles?) and it feels the same as when I got the vehicle at 30k kms. Car has been tracked a few times and generally driven pretty aggressively but with mechanical sympathy.

Otherwise, I wouldn't be surprised if its still going at 180k.

I guess that's where I'm surprised because I do use it for deceleration as well with a little slip. How similar of a process is the changing of a clutch/TO bearing/slave cylinder/etc to a RWD job? I have no ability to conceptualize the inside of a FWD transmission.

Main difference is needing an engine brace(goes over the top of the engine bay and just hold the engine while you remove the transmission since the transmission on most FWD is part of the engine support mounts) Honestly, its not that bad.

Has anyone gone from an 8v A3/S3 to an A5/S5 Sportback? I want to trade in my S3 for an S5 but cannot visit the closest dealer due to COVID restrictions, and want to know from other peoples experience how much roomier the cabin feels, if at all. Obviously the cargo is much better, but is the front seating area appreciably roomier? Secondly, is the front seating area of the S5 literally the same as the A4/S4? Seating position etc? Obviously the interiors look identical.

Yes, the front A5/S5 seating position is the same as the A4/S4. The rear seating is different due to the A5/S5 being a coupe or sportback.

Aw poo poo guys, I just got a 2014 S4 with 48k on it sent on my way from Carvana. It's a DSG car in Estoril Blue. I've been eying a B8.5 for a while and finally found a good color/Combo/price. What do I need to look out for or check first? I've got a line on a good independent VAG shop in my area and thinking of having them check it out while it's in the Carvana trial. Give me advice German car experts!

I don't think there were any big issues with the B8.5. Audi addressed a lot of the issues of the B8 with the update. Maybe have the shop check to see if it has a tune or check the flash counter to see if it's ever been tuned. If you're into it, the APR stage 2+ tune, transmission tune, throttle body upgrade, cooler, pulley upgrade, freer flowing air filter, and intake tube will run you about $4,000 and will have the car putting out about 500 HP.

A month ago I bought a 2018 VW Golf, 1.8T TSI manual (originally was planning for a GTI, but a TSI will do for now). Since I have a 20+ year gap in driving a manual, I was pretty much a total noob. I've been working on and improving in the dark arts of it and I'm getting better. But, one dragon's head is still rearing after all this time: going smoothly from 1st gear into 2nd gear. It seems to me that if I get up to 3K RPMs in the 1st gear, when I shift into 2nd it takes a bit to for the RPM to come down. If I let go of the clutch too soon/late it jerks me. I have to somehow get it just right. If I am driving uphill it's even worse, since the speed drops but the RPMs don't and I just have to let go of the clutch to not end up going into 2nd at 15KM/h. I plan today to find some parking lot in the town to practice this specific thing, but I was wondering if I'm missing something. You guys who know VW engines and transmissions maybe have suggestions? The other gears have gotten better, this 1st to 2nd shift is, for now, still a mistery.

Seems a bit odd to me, I don't think there's much of a rev hang in my '19 alltrack although I believe the tuning is somewhat different and the gearbox is not the same. I think it's probably a matter of timing and practice, but if you can take a short video showing the rev hang that might be helpful.

I also just picked up a 2015 S4 in Volcano Red. Its got the DSG with 46K mi. I just took it in and got the PVC valve replaced (it was consuming oil) and while they were in there did a walnut blast on the valves. Also, another while your in there, they did the thermostat. The B8.5 got the updated PVC and water pump and should be reliable for a while, just look out for coolant loss. I also plan to do a DSG and rear diff (sport diff) service by 50K just to make sure. FCP Euro has some really good videos on the service and maintenance on these vehicles with recommended services. Also FCP Euro has lifetime replacement warranty on their parts, yes even consumables such as spark plugs and brake pads. I don't know how they do that.

Likely the implementation of dual mass flywheels everywhere now that wasn't as prevalent 20 years back. Practice but some of it may just be learning to shift around it if it bugs you.

The car I learned to drive and drove for a bit 20 years ago was my dads that was 20 year old car at the time (has since changed it). Which was based on a Renault design from the 60s, probably not updated much. So we're talking at least 40 years of technology differences. While I have no idea what "dual-mass flywheel" even means, it would be a safe assumption that that car didn't have it.

I've got a 2017 Golf TSI too, and I'm not the smoothest shifter, but I'll take a crack. One thing is I think I typically do that shift a little earlier than 3K, say maybe 2.5K or even 2K if I'm on city streets. I really don't pay much attention to the tach though and try to listen and feel for when I should shift instead. I think the shift points are going to change based on how aggressive you are with the acceleration in any given situation too, so I think at some point you have to focus more on the feel than the numbers (could just be me though, I've really never been a numbers person). Another is really trying to do things stepwise. Push the clutch all the way in, then shift, then ease on the throttle as you ease off the clutch. The 1-2 shift is definitely a hard one to keep smooth, but sticking to some basic principles like those help me. Coming from a ratty Honda Fit, the shifting really was different but I've gotten used to it now. I think you'll get the hang of it too, but it does take some practice.

I know this is an issue with GTIs that commonly gets modded, so probably applies 1.8ts too. They put in a clutch delay valve, so there's a disconnect between when you left off the clutch and when it actually engages that for me caused a lot of clunkiness between 1st and 2nd. Though I think if you were having an issue with that you'd be low on revs between 1st and 2nd.

Thanks for the help everyone. Yes, practice will essentially make it hopefully flawless (if for anything, but for the good of the engine and transmission). With a bit of practice today I think I got better, but on the street with cars on my back ...it's a hit or miss. I hurry, and sometimes I shift fine and other wise I just miss it. Oh well.
