I was at the dealership the other week inquiring about a 2012 Jetta Sportwagen. The sales person there mentioned in mid 2012, the TDI is supposed to get a timing chain vice the belt. Anyone heard this news ?
No.Has the 2.0T gone back to a belt???
A properly designed chain NEVER requires replacement.yeah but how much does it cost to replace a chain, at what miles?
No.
And a properly designed chain is much better than a belt. That requires a $1200 service every 100k miles.
I disagree, but even then, VAG has never really "properly designed" a chain drive, so.... And it should not be costing anyone $1200 to service even the MOST expensive TDI timing belt.
rubbish.A properly designed chain NEVER requires replacement...
I've owned 2 MB diesels with 275k (11 years) and 260k (10 years), one gas MB (14 years) and one Nissan (15 years) with over 200k miles each plus many other vehicles with chains with over 100k miles and never had an issue with chains or guides. I'll take a chain anyday rather than paying for what say 20 timing belt services.rubbish.
Ask anyone with an MB diesel. Standard interval is 200K mi for these.
I think the chain in an overhead cam engine is stressed more than OHV (like your crown vic)
Like I said, properly designed chain. You listing out failed designs by MB and VAG serves nothing but to add to my point.rubbish.

So you're planning on going 2.4 millions miles on your CR TDI?I'll take a chain anyday rather than paying for what say 20 timing belt services.
My bad about the crown vic engine being an OHV.Like I said, properly designed chain. You listing out failed designs by MB and VAG serves nothing but to add to my point.
timing belts are an incredibly expensive maintenance item, doing away without them keeps cars more economical and reliable. Modern day toyotas and fords have been very reliable in their designs.
You clearly don't even know the design of the engine I am referencing (4.6L Ford V8) since it is a SOHC design.
No, the 20 is if all the cars I've owned had timing belts instead of chains plus using 80k intervals.. The 20 might be a little high since I didn't keep any of my first 1/2 dozen cars or so past about 60k miles. The only car I've owned that I had the timing belt service done on was my 2000 B5 in 2005 for a little over $500.So you're planning on going 2.4 millions miles on your CR TDI?
(20 belts x 120,000 mile interval)
Bold in mine, from a guy who actually SEES cars every day.timing belts are an incredibly expensive maintenance item, doing away without them keeps cars more economical and reliable. how so? Modern day toyotas (ROFL! You really need to research Toyota's crappy newer engines before that statement). and fords (LOL, yeah, sure... Duratecs blowing up at only 200k miles, that is great!) have been very reliable in their designs.
You clearly don't even know the design of the engine I am referencing (4.6L Ford V8) since it is a SOHC design. (yes, so long as you can keep the oil and spark plugs in them, and they have TWO chains, BTW)
No, the Golf R uses a chain.I hope they don't give the TDI a chain... they are finally once again 100% chain-free on the 4 cylinders sold here. Belts are SO much better on Volkswagens.
The 270hp Golf R[20] uses an EA113 based 2.0L engine. It is not the 201hp EA888 engine. But I was referring to the diesels, which so far thankfully are still based on the EA113 engine design. It does use, like other DOHC EA113 engines (as well as DOHC EA827 engines) a chain to operate the second camshaft off of the first. But a proper belt is still used from the crankshaft. It is not simply an uptuned version of the GTI engine. But the real kicker is, it uses a chain driven dual balance shaft... which us BHW owners know all too well VAG really failed hard on... so I'll keep the Golf R on my "admire but do not buy" list.No, the Golf R uses a chain.
This! VW and chains makes any timing belt issues they ever had seem like a blessing. They suck when it comes to chains.I disagree, but even then, VAG has never really "properly designed" a chain drive, so....
The petrol chain driven oil pumps have no issues at all. I have not heard of one single incident with the actual chain drive to the oil pump and it has been used for over a decade now in the 1.8ts and other applications. I mention the 1.8t because there are people making 500..600..700 and beyond hp with them without a problem and hundreds if not thousands running around with 300+hp as daily drivers, my mk4 is in the 300whp range and has 130K miles without incident, its had an upgraded turbo on it since 6K miles and chipped since about 2K.But the real kicker is, it uses a chain driven dual balance shaft... which us BHW owners know all too well VAG really failed hard on... so I'll keep the Golf R on my "admire but do not buy" list.
Nah, mine will be hear in late Feb. I really was under the impression that the R used the older engine design. I feel better now, especially after confirming this with Google.The 270hp Golf R[20] uses an EA113 based 2.0L engine. It is not the 201hp EA888 engine.

The current 4 cylinder TDIs sold here, on the other hand, employ a belt to operate one cam, the second cam is driven via a gear, and the balance shafts (where equipped) are also driven via gears. No chains anywhere! Too bad they seem to have failings in other areas.
I'm going to have to pick your brain about this at some point, because 600hp is around my target level for the final version of my R.The petrol chain driven oil pumps have no issues at all. I have not heard of one single incident with the actual chain drive to the oil pump and it has been used for over a decade now in the 1.8ts and other applications. I mention the 1.8t because there are people making 500..600..700 and beyond hp with them without a problem and hundreds if not thousands running around with 300+hp as daily drivers, my mk4 is in the 300whp range and has 130K miles without incident, its had an upgraded turbo on it since 6K miles and chipped since about 2K.
On the 2.0t EA113 there are some issues with the balance shafts at higher power levels. APR before going to the EA888 motors actually removed the shafts in their race cars and many people do that on the street as well with higher power applications. I converted my A3 with an Ea113 2.0t to a 1.8t style oil pump and removed the balance shafts all together. Car makes 600+hp and has over 40K miles on the current setup without a problem.
I did forget to torque the bolt right once and the pulley on the pump jumped eating a motor I just built in a few hundreds miles.. whoops, that was expensive.
