Engine rattling noises when starting engine

Source: http://volkswagen.msk.ru/forum/index.php?showtopic=176433&view=findpost&p=3031289

Last few month I hear a lot about this VW fuckup. I knew this before but recently a lot of TSI owners bring this up.
If you happen to hear same sound like on video when you cold starting your TSI car, keep reading.

Don't confuse with fuel pump fail - https://www.youtube.com/watch?v=fgNkolvCR_U

The reason is chain lengthened.
As consequences: chain can jump few teeth and valves can meet pistons.

If owner come to dealer with this strange sound, they replace to new improved chain, tension and chain cover with protection from jumping. Even if guarantee is over they do it for free upto 3 or 5 years, I don't remember.

How to avoid it or to delay this issue? Yes, it will happen if your engine was build upto 2011-11-01, see attached TPI below to check your engine serial number if it has upgraded chain set. Always use hand brake when parking! Do not park your car with gearbox only.

Person, who works in VW dealership, advised about these life time of chain:
1.2 TSI - 30'000 km
1.4 TSI - 80'000 km
1.8 TSI - 120'000 km
2.0 TSI - 120'000 km

I can add only that I drove a little more than 30'000 km on my Fabia and I have no issue with it. New owner came yesterday at 53kkm - no issue yet.

Now, I found some assumption that chain condition can be diagnosed with VCDS.
ECU continuously adapting to chain length checking valve open/closed angles. If they exceeds limits - check engine will light up with error "P150D00 chain elongation".
After replacement you should erase adaptation values. There is a message from VAS tool that confirm this: "If the adaptation values are not erased after the timing chain has been replaced and/or worked on, damage to the engine can result. It is absolutely essential that you follow and observe the instructions and notes in the Repair Manual!".

Another interesting information I found that on new 1.2 TSI engines (code CJZB), they will use... toothed belt! :-) VW commented: "replacing the original timing chain mass given argument is that the belt drive is quieter, noise when driving is more quiet."

And we did some research.

This is mine Fabia, the I did yesterday oil change service for him and we took readings. No rattling, normal values.

My oil change

My first own oil change. Same oil Valvoline SynPower 5W-40 4 liters from Alon Halafim. This is last time I bought there - 220 NIS! And they sell for 220 while on site it says 200. When I talked to them on phone after finding that fact right after purchase - I got filling like talking to wall. Ok whatever, there are other stores around. You can get 5L for 190 in AutoStore (Holon). Original oil filter with plug I got for 50 NIS from Russia.

Tools
1. Jack stands - 140 NIS

2. IKEA - TROFAST - Storage box, green ~15 NIS

3. IKEA - CHOSIGT - Funnel, set of 2, assorted colors ~5 NIS

4. ACDelco ARM602-4 Torque adapter - 300 NIS (optional)

And here we go!

Procedure as described in old post - Oil replace instructions.
1. Remove filter (put paper towel around before).
2. Unscrew oil cap.
3. Clean both places, cover both holes with something to keep clean from dust.
4. Go below, put oil pan (storage box).
5. Unscrew drain plug.
6. Let it drain out for a while, at least 10-15 min.
7. I had 0.5L of oil in old canister, so I filled it in washing out more dirt oil.
8. Now prepare new filter, tap gaskets with oil and install. Torque moment up to 25 Nm.
9. Screw in new drain plug, torque moment is 30 Nm.
10. Top new oil using funnel periodically check for level with dipstick (top, wait for 1 min, check). 3.6L required by the specs.
11. Clean with soft paper all places and check for leaks.
12. Startup engine and check for leaks.
13. Perform test drive, shut down engine, wait for 3-5 mins and check for leaks again.
14. Done!

I hooked up with VCDS while topping oil monitoring fill level and temperature.

And did test run while monitoring.
Blue - oil level, mm
Green - oil temperature, grad C
Purple - coolant temperature, grad C
Orange - engine RPM
Yellow - vehicle speed, km/h

After engine was shut off, oil level sensor displays ~79mm and on dipstick it's in the middle of min and max. I  run out of new oil can because I waited for about an hour while old oil was draining out - doing other stuff.

Now need to return old oil gently collected in old canister to somewhere. It was fun, saved a money (about 300 NIS for labor) and got new experience. Engine runs smooth, I felt better response on gas pedal after change - true.

Few more shots
Oil spot quick check (photo taken after 10 mins)

Filter housing. Note small spots on the right side. Not a mud, just some sticked oil like sludge but very easy dissolves when touched.

Oil level sensor from Hella. Costs ~$85. Check Hella PDF below if interested.

First service soon

Reminders on display

Yesterday I passed 14 000 kilometers. This morning I saw new sings on display when started my Fabia. This mean that I have less than 1000 km or 82 days to service check.

Need to buy an oil, I think it will be Valvoline SynPower XL-III. Once I'll get it, will call to garage to schedule a date.

Champion Motors *6363

I got this card with my new car. This is 24/7 Champion Motors service for VAG car owners. Backside says that I can get:
- Technical support for any question or problem regarding the car
- Wheel changing and fuel filling service
- Towing vehicle service
- Help in small problems starting the car
- Navigation to any destination in the country
- Traffic information and re-navigation
- Fuel station, pharmacy, ATM locations and more
- Weather information, currency rates and more

This Friday I was looking for some security stuff and decided to check if they can help me.
So I called *6363 and a girl answered me. She said that regarding security questions an authorised person will call me back on Sunday and checked my details. She knew from my mobile phone number who I am and what kind of car I have - that was nice.

But till now nobody called me back...
Also, there is an asterisk saying that they can stop providing the service anytime. I hope it will be available for at least 2 years of car's guarantee.

G12 plus plus

I meet today a friend of mine in VW garage in Netanya and bought a bottle of original coolant to be in the just in case - 1.5L for 65 NIS.

What was on labels

Suitable as a filled-for-life filling.
G12plus plus distinguishes itself through the miscibility with the products G12 and G12 plus. Provides protection against frost, overheating, corrosion and scaling. It is recommended to use this product all-year round. To be used as described only.

Harmful if swallowed. If swallowed, seek medical advice immediately and show this container or label. Keep out of the reach of children. Keep away from food, drink and animal feedingstuffs. Do not breathe vapour. Avoid contact with skin. Dispose of this material and its container to hazardous or special waste collection point.

For me was also a new that coolant should be mixed with tap water in 1:1 proportion, I thought that it's ready to use. Actually, that's very smart, check the manual:

The coolant which you use for replenishing the system, must comply with one specific specification. Do not use an alternative additive if the coolant additive G12 PLUS - PLUS is not available in exceptional cases. Just top up the system with water and as soon as possible arrange adjustment to correct the mixing ratio of water and coolant additive again by a specialist garage.

You should always have a bottle of water in the car. It's useful to wash hands in a field or... rescuing your engine from overheating and damage. When level is extremly low and you havent G12, add a water, but remember how much you filled (say, 0. liters). Keep an eye on temperature and get closest garage or service and add same amount of G12 - 0.5 liters to get right proportion back.

Also, small tip. Never, I mean, NEVER buy oil or coolant at petrol stations.
