Can anyone with access to technical info on this engine confirm whether it is to be fitted with a Life-long cambelt ?


A rumour I picked up...

Have the answer now.


The new 'Longlife' cambelt is being fitted to the 1.2 and 1.4 Ltr petrol engines only.


It supposed to last the lifetime of the car ...

No that isn't right, the 1.2 TSI and 1.4 TSI have a chain (not a belt). In theory the chain will last the lifetime of the car but in practice they can still have problems unfortunately.


The 2.0 TDI is still belt driven and needs to be changed as per the intervals.

The Mk7 Golf has a petrol 1.4 & 1.6 engine, both with cam belts. The 1.2 still has a chain, as do other engines in the 1.4 size range. However, the 2.0ltr (in fact all the diesels) still use belts.

Although there's no 150bhp 2.0ltr TDI engine in the Mk7.

There is a 150PS 2.0 TDI in the MK7, and there is no 1.6 petrol. The 1.4 TSI petrol is chain driven

Think you might be talking about the MK6!

Just checked the VW website, and there's no mention of a 150bhp
engine in either petrol or diesel. Diesels come in 1.6 - 105bhp and 2.0 -
140bhp. If they make a 150bhp, they're not listing it. Then checked Etka and they list the 150bhp engine on there. What's going on there? However,
you're correct there's no 1.6 (I was looking at the Mk6).

Also checked Etka, and there's detailed parts breakdowns for
toothed belts on the 1.2, 1.4 petrol engines, and also on the 1.6 and
2.0ltr TDI engines. None have a chain detailed. I think we're both partly right or wrong.

Hmm seems to be quite a lot of confusion


I'm surprised about this notion of a cambelt for life, I was certainly not aware that is possible and I'm surprised if they've reverted to using a belt on the 1.0 3-cyl in the UP/ Citigo/ Mii


I can say for 100% the 1.2 TSi and 1.4 TSi are chain driven, got quite a bit of knowledge on those two.


Diesels are generally all belt driven, as are the old school 1.4 and 1.6 N/A petrols from MK4s and early MK6s

Here's a screen shot of Etka. No mention of any cam chains at all in the Golf range.

Hmm very odd as in all other applications the small capacity TSIs are chain driven, and this is fairly widely documented. Try checking the same engines in the Polo 6R?

Are we all talking about proposed engines for the mk7


Could it not be that a 1.4 petrol engine in the MK7 will have toothed belts rather than the current chain drive ?


Does EKTA show details yet of the new 150 ps diesel engine

Do the engine codes on ETKA match between the Polo 6R and Golf MK7 for the 1.2 TSI and 1.4 TSI? Still think it seems crazy they'd re-engineer them as belt driven

Bit of a mystery then, out of those 6 codes I could only find any reference to the last 2 on this VIN decoder site

http://www.vin-decoder.net/vin_WVWZZZ6RZDY000020


Any ideas if they'd all be EA211 based? That looks like its belt driven

I can quite see why VW have re-engineered from chains to 'longlife' toothed cambelts on the newer engines especially if the reported failures at under 30k miles are true

I'd disagree. It's priced in line with the competition and given the Golf is percieved to be best they don't need to undercut others. Also it's worth remembering the majority of these sold new will go out on PCP and lease deals where it's the monthly price that counts and residual value. I've no doubt it will remain a UK top ten seller although the 1.6 TDI SE is likely to be most popular.

Had a discussion with my dealer Service Manager re Longlife Cambelts.


He said the MQB based cars are for life of the vehicle including Diesels which obviously interested him when this was announced to him in Spain & his training since returning.


This is apart from the recently announced change to 5 year change intervals for some recent MK6 models.


It will be interesting to see if VWUK service schedules reflect this for the MK7 or if they will set their own parameters to request ' cambelt inspections' at  'x' iintervals

Going back to the original post, anyone know if the 2.0 TDI 150 (CRLB/ CRBC) is just a retuned version of the 140 from the MK6 or is it an all new engine?

I remember reading  a review or tech write up that gave the impression it was an all new engine with the only similarity to the previous engine being the dimensions between the cylinder spacings & one other dimension which I can' t remember.


If I find the article I'll post.


One article but not the specific one I remember going into real detail about the new engine is

Interested after reading through this thread - we have just got a MK7 GT 150 TDI for a new company fleet car which I always seem to bag myself for long customer trips. The dealer told me that even on our mileage (30k+ pa) that we would not have to change the belt. We are on a maintained contract anyway but it seems the dealers themselves have got their wires crossed when it comes to the belt.

I know what you mean about dealer confusion..


The concensus from those I have spoken to seems to be an ' inspection of the belt ' at  ' x miles ' and no automatic replacement at timed or mileage limits as on the Mk6


What do you think of the Mk7 you use then ?

Its a great car - very very refine on the motorway.  The adaptive cruise control gets used more than any other feature and is worth its weight in gold (despite it being free on the SE and above!).


The engine is still very tight with only 900 or so miles on the clock but its still managing to return around 55mpg on the motorway run.


The electronic handbreak isnt to everyones taste but having driven audi's with it on, im more than used to it.


Would I buy one with my own money - yes.

Thanks for those links Med3, sounds like it is indeed a new "EA288" based engine. What's interesting is apparently the 1.6 TDI will also switch over soon, will be signalled by a slight power increase to 110PS.

lucamag- is your companies the manual or DSG?

We have one of each - I have only driven the Manual one however I can imagine the 6 speed DSG is the same one that I had in my Scirocco GT.
