The great big MK6 Golf 118TSI tuning thread

[ohhbugger]

could anybody tell me if these 118Tsi modifications that are listed in this thread are still applicable to the 118Tsi engine that is found in my 2014 beetle ?

Once the car get's a few km's on it i would like to extract a little more power from it.
from the photo's on the previous pages the engine bay on my beetle looks identical.
im interested in the following
*APR tune
*Intercooler upgrade
*short shifter for 6sp manual
*Exhaust and intake upgrade

Is this doable ?

[ohhbugger]

can anybody answer my questions ? or is there anybody still reading this thread ??

Don't know anything about the Beetle sorry

It looks like it's the same 1.4L Twincharged engine so I'd guess pretty much all parts will transfer across, but that's still no guarantee.

Short Shifter
Your gearbox is probably the MQ250 the same as mine and uses this shifter (which is awesome):

I've used the MK3 variant (which is highly sought after) and this new one which is also brilliant. Well worth the investment and easy enough to fit if a little fiddly.


Engine Tune
What's your engine code? I believe the newer variant of the twincharger in the Polo GTI can't be tuned due to new encryption but don't know which engine they are using in The Beetle.


S3 Intercooler
Probably. It fits in place of the stock unit with little modification to the pipes... so probably.


Exhaust
Off the shelf?? who knows. If it's being custom made, then it's really not a question. But be aware that there isn't a downpipe for the 118TIS that I am aware of which leaves you with cat back systems only.


Intake
I haven't seen the engine bay so can't really comment, but most are made to fit specific mountings so it's a huge maybe.


Bottom line though, it looks like that particular model/engine combo is available in the UK so there is a chance someone is making parts for it.

Intake
I haven't seen the engine bay so can't really comment, but most are made to fit specific mountings so it's a huge maybe.

If the engine bay matches the Golf's then the intakes available for the 118 should fit.

What is the best year to tune? And there are a few comfortlines, can these be tuned or an I supposed to look different model? Sorry if hsve been asked

Anyone who did the intercooler swap: do u remember what the part number was for the stock cooler you removed? Also did your hoses have connectors to be cut or did it come with garden hose clamps?

Part number for my stock intercooler: 1k0145803BM

[Rawcpoppa]

Just thought I would post up a few things even though I am doing the swap on a jetta:

My intercooler is 1k0145803BM. It's dimensions are 31 mm x 418 x 647 mm. I'm surprised it's this big as the S3 intercooler I have is 37 mm x 416 mm x 646 mm.

1k0145803bp - s3 intercooler has 32 bars of fins vs 30 in the stock intercooler. The fins on the s3 intercooler are also smaller so there are more of them that way as well.



S3 intercooler has the yellow covers attached in pic.

Finally I encountered garden hose clips (not sure what the right term is) so didn't have to cut my hoses to fit them onto the new intercooler. All of this should apply to a golf.

Hi guys,
I'm currently investigating some mods towards my golf 118 tsi with a tune and exhaust being my first options. Since reading throughout this thread I've chosen to go with the stage 1 apr tune, but I was curious as I am betting this has been asked before are there any aftermarket exhausts that anyone is aware of, and sorry for bringing this question up again. On that note this is the only one I have found but other then that I'm guessing that I'll need get a custom exhaust?

Thanks again.

The Beetle uses a new Twin Charger engine designated CTHD (similar to Polo GTI) I believe main differences is forged pistons and new ECU. This ECU has new encryption that needs more work for tuners to apply their tunes meaning ECU need to be opened and worked on.
"Before a bluefin can be used on this model, the ECU must be "bluefin enabled"

The vehicle's ECU will need to be removed, opened, reprogrammed and refitted, which will then allow us to communicate with the vehicle through its onboard diagnostic port. This process is done with specialist equipment at one of the Superchips dealers listed, from whom you buy the bluefin at the same time.

The process is not detectable diagnostically by the servicing dealer".

Just to note, the Beetle we have is based on the Jetta and not the golf so expect some physical differences
