Difference between the 125 and 147 petrol models?

[Torn]

I Picked up my 147 on Friday, its a work car also and was toying with the 125 or 147, my dealer only had a TDI for me to drive so had to go off the specs, plus i was very limited with what options i could get unless i wanted to wait 6 months.

After adding up the options i wanted and adding on the aditional options to the 125 to bring it up to spec there was only about $3000 difference.

Some of the things the 147 has like the under seat storage, better seats (sports with lumbar support) and new 2010 fabric as well as the performance increase pushed me into the seat of the 147.

with regards to the satnav, i have a tomtom 730, for me the advantages are that i dont have to pay $300 or so a year for updates which is what normal Factory OEm ones are, updates come out 4 times a year, map share etc..etc.. As well as the ability to use it in my partners car if we need.

Factory head units are targets for theives also as most people keep the security code in their glovebox, where as the tom tom is easily removed when you leave the car, i keep a microfibre cloth in the car to wipe and marks from the windscreen where its been so not to tempt said theives.

Is there any difference between 125 & 147 engines?

Hi guys, im looking at buying a tig in a few months for the misses.
Apart from the cosmetics is the 125 and 147 the same engine? The APR aus tune is the same kw's for both engines right?
I read the tig uses the S3 driveline (DSG) is this correct? I assume for the extra car weight.
For an extra 22kw I cant justify the extra $7000 ish for the 147.
Thanks.

yes same engine, so if you're going to do the APR remap, they will come out same spec. 147 just gives you luxury extras. Good value, but only if you are looking at upspecking a 125 to similar levels - then you might as well go the 147. Otherwise the 125 with the APR remap is exceptional value for money. Where else can you get a 190kW, 400Nm SUV with all the features of stock 125 for well under $40k?

New Tigs now run 7sp DSG - first model ran standard auto.

BYW, it's not just the kW increase that you get with the remap, it's the massive increase in torque that makes it such a worthwhile upgrade IMO. It would still be highly worthwhile to do the remap with the 147 to get the torque improvement.

All this is just my opinion of course

Same engine in the 125/147 and the Mk6 GTI

Engine code EA888

So, just out of curiosity, is the extra 22kw just from factory fuel mapping differences, or what?

Actually EA888 is the engine family not the engine code

It is entirely due to the ECU map from the factory. Every physical component is the same in all the cars that use the EA888.

Hence the reason that an APR ECU map is such good value on a 125TSI ....

The engine can be the same but the engine bolts on and the accessories could be different. To be 100% sure you need to speak to VW or at least try to get SSP (self study) for both engines, so you can compare them better.

I know for sure that when VW engine that appears the same to 147TSI comes in VW/Audi car, has a lot of internal changes to hold the extra power when it is factory tuned to 190kW.

But yeah, you might be correct that there could be no internal changes in the engine that is in Tiguan 125TSI and 147TSI.

This should give you some idea what is the difference between the engines that have the same cubic capacity but different power output and it doesn't matter what engine family they are.

Taken from Wiki.
notes:
the 169 kW and higher versions have stronger pistons and gudgeon pins, new rings, reinforced connecting rods, new bearings, reinforced cylinder block at the main bearing pedestals and cap, new lightweight aluminium-silicon alloy cylinder head for high temperature resistance and strength, adjusted exhaust camshaft timing, increased cross-section high-pressure injectors, 1.2 bars (17.4 psi)(value only valid for Audi S3(8P))boost pressure K04 turbocharger with larger turbine and compression rotor (S3,Cupra,Golf Ed.30) - which some components are NOT shared with the lower output variants

I have the self study guide for the EA888 from before it went into MK6 GTI (in its 147kw form) and there is no mention of Valve-lift or those "extra goodies" that the Audi engines have on it to get their standard forum of 155kw & 350Nm. So Transporter is correct in that not all EA888 engines are the same.

However, in the case of the two Tiguan versions of the EA888, everything that I can find indicates that they are physically identical and it's only the ECU tune which differentiates them. I wish I had updated self study guides or service manuals to confirm!

Factory 188/195/200kw 2.0 T VAG engines are not of the EA888 family and yes they have substantial internal differences.

Also, A3s now use the EA888 and they do not have valvelift and are the same as the Tigs etc.

Audi's with longitudinal engines (and valvelift) are not of the EA888 family either.

[bmarshall]

APR warranty there 125/147 tune though dont they?
I assume the 188/195/200 have different internals because they share the k04. If you remap these you would expect 230+ figure.

[Corey_R]

Maverick would disagree there.
As would the Wikipedia

Plus, it would seem really strange for Audi to completely design the EA888 themselves, and then not use it in their products than the A3.

My bad .... yes, Audi's longitidunals are EA888 relatives. However they did not "design" the engine series .... merely redesigned the head .... Valve-lift heads are completely different, even the inlet/outlet spacings are different, hence the problem in fitting the Valvelift head K04 to a non-Valvelift head.


But back to the point .... MK6 GTI/All TSI Tiguans/147TSI Jetta/TSI EOS all have identical engines ..... every single engine part is interchangeable, even though some part numbers may vary.

[Corey_R]

Aah - when I say Audi designed them, I mean that Audi and Volkswagen say that Audi did, and hence their training manuals and the wikipedia etc say Audi design them I, am not mechnical at all... I'm just good at collecting and sorting information


But yes, in the essence of this thread, I agree with you, that the Tiguan 125TSI and 147TSI have completely identical engines.
