Other cases of TSI engines defects

Browsing the internet for finding a cause of my problem, i found some VAG cars users that had serious problems with these engines.

One of them is this post HERE.

The thing that got my attention was:

A) Piston Rings

After it was finally admitted in late 2011 that there was a problem leading to engine failure(bearing in mind the engine came out in 2010), SEAT offered customers new piston rings.
Actually, what they were doing was fitting completely new pistons. It was VW trying to delude the customer that it was a minor piston ring batch problem rather than a major piston design problem.
In truth, its the pistons that were weak full stop and couldn’t handle much punishment before they failed. The specific problem was that the part of the piston between the rings used to crack and then come away, damaging the piston rings and eating into the cylinder bores* (although these have proven to be very strong due to being plasma coated).
There have been examples of totally standard cars having piston failure and these tend to be early cars with the original ignition hardware and OEM ECU software. Then when you add an ECU map you are bound to have a failure.
When these pistons crack, oil consumption is increased as it enters the combustion chamber, also lowering the effective octane value of the fuel being injected**. This is not the only reason for oil consumption and equally the culprit is the turbocharger, especially on cars with aftermarket exhausts. I will talk about that later.
Its easy to blame the pistons but its not the whole story. If the car was used for daily driving and not running massive amounts of boost, there’s no reason why these pistons should be put under such an amount of punishment that it would result in failure……..unless there are other contributing issues, which there are. Read on………

Solution: Revised pistons 2012 onwards and come as standard in the CTHE/CTHF engine codes.

NO.1 – this is mine

NO. 2 – this ain’t mine, but it looks exactly the same with mine, right?

* – As you can see in the image in the right (NO.1), the problem extends to 1,2 TSi engines, not only to 1.4 TSI.

 

 

** – If this is true, i must say that before the damage on my engine happened, the oil consumption increased to up to 1L of engine oil at 8000kms, but because in the maintenance book was written that a consumption of 1L every 5000kms is normal on some engines.

 

 

Can you believe that the image NO.2 it is not mine and it is borrowed from HERE? Use Google Translate so you can understand the problem of that user.

 

 

 

 

LE: i’ve found another similar broken piston HERE. See Img NO.3

NO.3

A worrying case is this with a Fabia, HERE.

An user posted: “If the car has full service history, then it sounds to me that there has been a manufacturing defect, in which case it may be covered 100% by EU law for up to 6 years.”

Good to know: “The price*** is for a factory-reconditioned engine, with 2 year guarantee. “A new one would be much more”.

*** – “Skoda will give 30% discount off cost of motor, workshop will give 50% off labour. Proposed cost: about £2200 / 2700 Euros.”

Other user said:  “I have a colleague of mine who drives a 2006 VW Golf V 1.4Tsi Gt with 102.000Km on clock and a month ago had his engine replaced with a brand new engine totally free of charge. The engine had a cracked piston and they told his that this was not caused by his driving attitude but it was a defect of the engine.” Well, it looks that VW recognizes this problem.

Some unhappy 1.2 TSI Octavia users from Romania made a written letter on the wall of Skoda’s Facebook page.

From this blog I took the picture above that i said it ain’t mine.

From there i learnt that this engine has about three versions of chains. Three!!!

Some users  talking about oil consumption of 1.2 TSI HERE, but not very complete discussion.

About  timing chain that has jumped off HERE.

A SEAT Leon 1.2 TSI owner has had to pay a lot of money  after chain jump and engine destroyed HERE. Use Translator again.

Remanufactured engine and parts bill

Labor bill

Secondpicture is the labor price. The price is in romanian money. To calculate use this: 1 Euro is about 4.4 RON/LEI, so we talk of a 1174 Euros labor bill.

First picture is the price of all components. Here only the engine’s price is 2017 Euros. Not to mention the other components’ expenses.

So for a VAG engine you’d pay other 3200 Euro at least to have a working car. And maybe you need an engine every two years?

Lately I received this comment from Joao Preto Paulo:

Hi,
It’s a misfortune to find this discussion, because it means I’m searching for problems similar to mine in order to write a complaint letter to Volkswagen.

Last day 26/November, my 1.4 TSI from a 2007 Touran failed, and after sent to a VW dealer it seams that the cause is a broken piston and piston rings. The engine was 91.330km and during nine and a half years it was used mainly for short local rides.

This happened just 230km after a water pump replacement and 6000km after the timing chain replacement, that despite of my complaints as been said by the serviced dealer that this was normal for a 90.000 engine. Crap talking!!!

Now I understand why my car had such an oil consumption specially when occasionally was making a long highway trip and the oil level lamp turned on. Last year I even put 2L of oil between two annual services (less than 10.000km) When asking the dealer for this oil consumption they always told me that it should be normal. Again crap talking!!

My car is on a local Volkswagen dealership, and after diagnosed the broken piston problem they gave me a 7.150€ budget for the engine replacement and working man hours, and it seems that Volkswagen it is not assuming any fault and sharing costs, despite I already had some information saying that they did so in previous cases.

Since those cases exists I suppose it should exist a number for an investigation case under Volkswagen development area in which they have found and admitted the fault. Any one have that information?

Thank you, body, for your comment. And I also thank  to all which will add their problem here.

Off-topic:

a)

A case of a bad manufacturing component read HERE.

b)

Another case of GDI engine carbon build-up:

Since I bought my 2008.5 Jetta with the 2.0 TSI (GDI engine) with 42,000 miles on it I was taking a chance with possibly having the carbon issue. After much reading, the TSI was not supposed to have the issue as bad as the previous FSI engine so I figured I was safe.

Well,  then check the pictures i posted with my engine and you can see a lot of carbon build-up at only 68.500kms.
