Some 110bhp engines will need fuel pump and injector upgrades before this sort of power can be realised.
#Vw cc chip tuning upgrade#
The OEM fuel pumps on the CR engines are generally good for around 240bhp, upgrade them and the injectors if you go beyond this or risk the dreaded limp home mode. The valve train system integrated valve drive module was used on the EA288. This design allows a range of EGR systems to be added to suit different market regulations. They retain the BOSCH EDC17 C64 ECU and are more economical than the EA189 but it is too early to see any patterns of faults. EA288 revision (2015-)įrom 2015 we see the EA288 engine released as the VW group move on from the emissions scandal the 110 and 150 bhp models have smaller turbos, and you can replace the turbo and remap quite easily. The Sachs racing clutch works well on this generation of engine, but we still think you'll be better off with a dual mass flywheel. The 140's can be mapped to around 170/180 happily and in my opinion are better than a stock 170 in terms of low end pull, but the 170's allow higher power gains so make a better base to work from. The 110's can be mapped to 140 fairly easily but beyond this you need to swap out the turbo, improve fuel delivery and use stronger head bolts. (There were either a Bosch or Siemens fuel pump used on these engines, the former flows better.) The pre 2010 110bhp and 120bhp engines will generally need an uprated fuel pump and injectors to cope with power gains above 160bhp and we would recommend you get stronger head bolts.

#Vw cc chip tuning software#
These 2008 engines were also implicated in the 2015 VAG group emissions scandal where the software would detect test conditions and reduce the emissions. The common rail engines are superior to the PD engines although there were a few minor teething problems on early engines. EA189 revisionĪfter 2008 CR (common rail) engines came in and had CBAB and CBBB engine codes. The VAG group 2.0 TDI engines have a lot to offer and if you know what to spot are reliable and have lots of tuning potential.

We are not trying to make out that these engines are particularly unreliable or full of issues - I recently bought one after doing my research carefully. We shall try to map out the differences between the engines and identify potential faults and issues with them.Īll modern engines have weak spots, by pointing these out we hope to prepare the buyer to spot potential issues early on. The VAG group 2.0 Diesel engines are very popular and have had many revisions and updates over the years. "Tuning, problems weak spots and complete upgrade guide."
