I believe the 1.4 and 1.5 use a dry belt. Also, the 1.4 was originally a chain design.
as found in late (Euro spec) Golf Mk5
and (again Euro spec) Golf Mk6
using a timing chain
. Turbo and exhaust on front
, intake on rear. Higher powered versions
(from 140 HP up) had both supercharger and turbo. Introduced in 2005/6. This engine is a
POS and VW for sure didn't do itself a favour with it. Audi tried to avoid this engine as good
as possible, only using it in a limited number of A1 and a 125 HP version only in the A3 8P.
from 2012 on (Golf Mk7 etc.) is an actually completely new design called EA211
using a timing belt
, while 1.5 TSI
is the revised design called EA211evo
, again with a timing
. All EA211 use a turbo only, no supercharger. Intake sitting on front, turbo sitting on rear
(quite similar to its bigger EA113 and EA888 brothers). Both generations of the EA211 basically
are flawless. Seems they learned their lesson. Nice little engines, perhaps the best ~70 HP (1.0
3-pot NA) to 158 HP engines currently available.
On a side note:
VTG turbo and Budack cycle on the 148/158 HP model? I never ever came across that and
I wonder if it's even true. When Volkswagen introduced the evo version of the EA211 in late
2016/early 2017 (which started in Europe with the facelifted Golf Mk7) only its 130 HP version
came with a VTG turbo and Budack cycle principle. The 150 PS/HP retained a conventional
wastegate turbo and relinquishes Budack cycle as it's hard to reach elevated power levels with
it. Same reason why you don't see Budack cycle on EA888 3Gs in a GTI or R but on 180 to 204
HP versions only. Same reason why the successor of the 1.8T required two liters of displace-
ment to retain similar power levels since it uses Budack cycle. Remember the latest revision of
the EA888 3G 1.8T had 192 HP in the Polo GTI and stage 1 Polos easily make like 250 HP.
