The great big MK6 Golf 118TSI tuning thread

[passat08]

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

I think Milltek did one in Europe

Finally got my car remapped. Stage 1. To those who have done it on their golfs, did you notice higher oil temperatures when cruising at highway speed limits?

Before, I used to see 92 deg C for oil temperatures when cruising around 95 kph. Now for the same speed it steadies at about 94 deg C. Seems logical to me but would like to hear what you observed with yours.

Never noticed, never been a problem

If you push really hard you can get it to 109

Are downpipes car model specific or just engine specific. I am looking for a downpipe with 200 cel catalyst to replace the stock downpipe.

[The_Hawk]

It's been a while but the last I looked there wasn't an off the shelf down pipe for the twin charger. Something about heat shields and bloody expensive

[Rawcpoppa]

I came across one from milltek in the UK but it's for a scirocco 1.4tsi hence my model specific question.

Volkswagen Scirocco 1.4 TSI Milltek exhaust

We now stock the Milltek Systems,

Use this site for info Milltek Sport Performance Exhaust Systems and email us for prices for your specific model (if you are in Australia). info@hp.net.au

[The_Hawk]

Wait... are you saying there is a full exhaust and downpipe available for the 118TSI Golf now??

[Guy_H]

cat back only for MK6 Volkswagen Golf Mk6 GT 1.4 TSI 160PS Milltek exhaust

But they do do a downpipe for the MK5 & Polo 6R - I can request a MK6 one - we have to have a business case for them.

[Rawcpoppa]

How feasible and beneficial is it to remove the stock cel and install a 200 cel in the converter as opposed to getting a new downpipe with 200 cel already installed?
