Update :
About 30 000km ago the egr valve and the maf sensor gave me some issues. The egr delete kit was brought in by
@Danny2 from Darkside Developments.
The kit is very good quality and everything fitted great. Then after a while I noticed coolant leaking from behind the water pump. The one screw was 2mm too long and when tightened pushed the water pump out. I managed to cut the excess of the screw but still had to remove the water pump and replace it with a new gasket. Did a coolant flush at the same time. No leaks so far.
Then the plan was to do OFHG , intake clean and swirl flap removal. After removing the intake manifold it was seen that OFHG were not sweating it was in fact the intake manifold that was leaking. The OFHG were postponed. Intake was cleaned using a liqui moly spray and fitted with a new gasket minus the swirl flaps. I asked
@Danny2 to also bring in the swirl flap delete plug as well.
The car drives alot better now like it breathes better. I still need to get Ricardo to sort out the errors when scanned (egr related).
I've since purchased a maf cleaner (crc brand) and have been using it at every 7500km intervals. No issues thus far and no errors related to the maf.
Thank you to
