Thanks! I plan to replace the G13 with G12evo next year, now I've fished out the silica bag, but if I didn't have to swap it over, I wouldn't bother. Hence my question.That is what we use now exclusively on MQB platform and I am testing it in our own cars to ensure there are no side effects but continuing to use G13 on earlier cars. One of the problems is cost, using G12E ramps up the cost of a belt change and a lot of people chase pennies when ringing around for this job so unless we can say “you must use G12Evo or else” then we can lose work. If it came in 205L barrels as G13 does we could pull the unit cost back.
