Hello All - Researching DIY 118 TSI engine rebuild

[sixboltmains]

Hello All,

Joined the forum for learning and moral support as I embark on rebuilding my 2009 Golf MK6 118TSI twincharged engine.
It has the usual misfire and of course the dealer has quote $1.8K just to open it and have a look.
And it will be between $5K to $7K to replace the pistons and rings.
I would prefer to do this myself.
Every man should go thru the process of stripping an engine once in their life and this is my chance.
Madness ? That remains to be seen. Wish me luck folks !

Regards,
Sunjay.

Agreed and good luck.
If it's not your daily, it's well worth the experience and frustration.
Haven't done a TSI, but I've done a 1.8T and VR6.
LABEL EVERY CONNECTOR.
Of course parts and machine shops are hella cheaper in the US.

Hopefully some enthusits can give you advice. Vwvortex is the best for VW. Don't bother with the Australia regional forum and wear a flame suit. I've had buddies that have had bad luck with the TSI.
Check the recalls.

Did you buy it that way or just started having the misfire or the misfire is getting worse?

Is it throwing any cels?

First, get it scanned with VAGCOM.
The ECU will tell you all the problems.
You will have more problems.

My neighbors misfires, but it's him trying to make his 4cyld sound like my VR6. Pretty sure his turbo is stuffed it has a leak. It makes a popping misfire
It's not a bang, but a pop, pop.

Do you know what cylinder it is? Pull the coil pack slightly on each plug and pull on the throttle.

If it is the engine.
Remove the font end (it's easy)), drain all the fluids.
Get new engine mounts and an OEM Dogbone.
Change all the gaskets.
Clean the crap out of the engine bay and polish and was it.
Polish any meat parts You can.
Check hot. Fighting is hard on me when

Hey skid plate,
Thanks for the reply.
We the 2nd owners of the car and its had an engine rebuild already 5 years ago - VW did it on good will.
Now the same mis-fire code is happening on cylinder 4.
VW is playing hardball and not wanting to contribute to the repairs.
Car has only done 80,000 kms.
We have changed the spark plugs and coils but same mis-fire issue on cylinder 4.
Looks like I will be getting my hands greasy this Easter weekend.

Regards.

...and it is more than 8 years old.

Bear in mind that, in AU the car manufacturers have to keep the parts in stock for 8 years only, though it's from the last model with the same engine sold.

Rebuilding the engine that was already rebuilt can have some challenges ahead. Hopefully it goes all smooth for you.
Good luck.

Scrap it and buy my Mk6 GTI with a decent engine.
