CAM chain tensioners failing..... TSI engines.

[MGV]

News i heard was they rectified the part that failed in 2011.

Does anyone know if this issue is common for Passat V6 3.2L engines? I have a 2007 Passat with the check engine light illuminated and DTC 00022 Crankshaft Position –Camshaft Position, Correlation Bank 1 Sensor A. In other words: camshaft timing out of sync with crankshaft. There are no nasty noises, but I'm not driving it till it's checked out just in case the chain is about to jump a sprocket or two.

I've read about several common problems on VW forums including:
1. Timing chain tensioner failure – it seems in 2010 VW introduced arevised part to cure the problemwith a Reinforced Timing Chain Tensioner
2. Bolt on centre sprocket fails or comes undone
3. Chain guide rails fail or wear out

It would be nice to think it could be just a sensor failure, but I don't think so. It sounds like a big job involving removing the front of the car, drive shafts and DSG transmission to get to the timing chain which is on the transmission side of the engine.

Yeah, I've seen the tensioners wear, causing noise on start-up. Also possible that the chains have stretched.

You don't have to pull the front off them to pull the DSG out. You'd be better off dropping the whole motor/DSG/bevel box out in one lump, and splitting it on the floor.

Thanks. I should have mentioned it's done 64,000 gentle km.

Hi all,


I eventually found my way here after my MK 6 Golf GTI 2010 suffered a total engine failure a few weeks ago.


Basically, a piston has has contacted the spark plug. Engine is seized. Most probably caused by a timing chain having slipped, so several independent mechanics think without stripping down the engine.


I am coming to the opinion that VW knew that the timing chain tensioner was an issue on this 2010 TSI engine (I have read the many forums relating to the issue), which went on to cause a catastrophic failure of my engine. If can prove this, then the car was probably not fit for use.

I also beleve there may be a TSB relating to the timing chain tensioner on this 2010 engine?

At this stage VW will not give a engine diagnosis, without stripping of the head at an estimated cost of $1500-$2000 quoted by JMC Hobart, so therefore goodwill cannot be applied for.


As such, I am now considering suing VW Australia, for either a refund or replacement of the vehicle, as I do not believe it was fit for purpose at the time of purchase.


Thought on this please, and has anyone successfully pursued this path?

My engine model number is CCZ

You may well have a case for a goodwill claim but you want to sue VWA for an engine failure the cause of which has not been diagnosed?

You need to go down the diagnosis path first before contemplating legal action.

The pistons would not connect with the spark plug unless you break a con rod or wrist pin
And certainly not due to a timing chain or tensioner issue

When the timing is too far out the piston can connect with a valve (inlet or exhaust)

If can prove this, then the car was probably not fit for use.

The car was certainly fit for use - it has been operational for over 5 years

There is a TSB - sometimes the chain stretches and the tensioner runs out of adjustment
If your car was serviced by VW they would have actioned the TSB and prevented the problem

On my car the timing chain became noisy after 3 years and 80,000km

As such, I am now considering suing VW Australia, for either a refund or replacement of the vehicle, as I do not believe it was fit for purpose at the time of purchase.

Complete and utter waste of time - you'll be left well out of pocket and still have an engine in need of an expensive repair

Thanks VW Convert for your reply. Engine has been diagnosed and I am following up the goodwill path now...

What was the diagnosis?

Let us know when you receive a response, good luck with the claim.

VW servive centre have confirmed timing chain has slipped

Not necessarily so, according to the legal advice I have received, if the product was manufacturing and marketed with a known defective component. See ACL

If your car was serviced by VW they would have actioned the TSB and prevented the problem

incorrect. Defective timing chain tensioner was not replaced by VW at the service interval

Complete and utter waste of time - you'll be left well out of pocket and still have an engine in need of an expensive repair

Completely subjective comment, and not necessarily true according to the legal advice I have received. Most likely outcome would be settlement before case went to court
