Scirocco Central

New Proud owner of a rocco, tsi 2.0 model after researching these forums for days, most mechanical problems seem to be aimed towards the petrol models rather than the diesel ones, is this a miss observation of mine, or as a rule are the diesels more reliable. Regardless I'm going to own a rocco, but debating Wether to look at making a switch from petrol, I imagine there will be a whole write up somewhere of pros and cons of both, if there is can someone link me?

Cheers all
Roc on

i would say the complete opposite most problems seem to come with diesels.

stick with the 2.0 TSI i love mine and they are really economical for a 2.0 T petrol engine. unless you are doing a serious amount of miles on urban streets then its not worth getting diesel

I think the most issues I've read about have been with the 1.4s although most of these have been ironed out.

This could be where the confusion is - had my 2.0 tsi for 3 years now and it has been a dream. Two new coil packs (very common with remaps) and a new battery. For the time I've owned it I think that's quite good going

Agreed, I did 35k in mine without problem and averaging about 34 to the gallon (dsg too) excellent car, as was the roc 177 diesel that replaced it.

Interesting Yeh I am seeing alot of 1.4tsi faults and a few 2.0, but just not as many diesel ones. In love with my current rocco pewter grey ! , averaging 32mpg around towns I can't complain !

Just got a lucky tax rebate so treating some mods I think is on the cards

remap has to be done if you havent already

Is on my list ! But I really need to sort out the 10ft arch gap [emoji30]

yeh thats is the other essential mod, most guys have either VWR or H&R lowering springs i have the VWR myself, never heard a bad word about either of them unless you want to go seriously low

I think I'm going to go for a 35mm drop, unsure if this scrapes though if so ill drop less

Only common issue I've seen with them is on the clutch release bearing. That's on older cars though, I think it was revised around 2012? So not an issue if you're buying a newer one.

Hiya, I have a 10 plate one so ill keep an eye, are they a expensive fix anyone know ?
Thank you

An official VW clutch release bearing ( central slave cylinder) cost me £84 about 6 weeks ago from my local VW, robbing bastards lol, but its a good quality part, with metal construction where as the original one was only plastic! But its good to get good parts when it comes to the clutch!

Nothing to worry about in expense really then ! Thank you

Seems the petrol is more reliable than I thought

Yeah the part itself isn't much. If it does go and you can fix it yourself I would definitely do that! The labor costs to repair it at a dealer are insane.

Do a quick search on the forum about Tensioner issues with the TSi. Just something to be aware of.

Sometimes if clutch oil has got on the flywheel and clutch plate, you might as well change it... In fact, while they are fiddling with the clutch, they might as well change it! So the costs mounts as BunnyJen implied, it's mostly labour.


The only other tsi problem I know is with the timing chain going out of synchronization... I am not quite sure about the mechanism of how it happens, but there have been a few complaints. Another one of those things that were revised on 2012 (circa) models.

There is a thread about common problems that was made by RW1; have a look for it

Thanks for that input bud.

Yeh I was informed any pre 2012 models had a recall aswell, for the chain but unsure if mine was. I'll listen for the rattle as atm it's running sweet (touches wood)

This happens when the chain tensioner starts to fail, resulting in the chain flapping around for a bit at startup.
The chain tensioner relies on oil pressure for proper tensioning. There is a spring which is supposed to put some tension on regardless of oil pressure but this spring can fail or get warn, the result is that when there is no oil pressure (ie startup) the chain is loose and can slip.

Also it is best to never leave your car in gear when you park, especially on a hill (when you tend to leave it in gear) - as if the car moves it will try to move the chain and this will happen when there is zero oil pressure, which again if the spring is worn out could cause it to slip.
You then come back to start the engine and it won't start - as the chain has slipped during the time it was parked = destroyed engine.
Not a problem for DSG, but manual drivers beware.

Regular oil services are essential on the TSI as there are many narrow oil passageways, and so many parts rely on good oil pressure. The camshaft adjuster (VVT) can stick, and this tensioner can stick briefly on startup if the oil is old.

That is excellent knowledge, I shall screen that, encase of any issues, not one for leaving it in gear
Hopefully stays running well

Amazing post!!! Thank you very much for that explanation...
