We don't have a manual on your vehicle because it is not offered here in the USA but we can help with more general information because it sounds like a pretty straight forward compression issue as you mentioned. So that means we need to perform the test and see what we have. Thanks

Sounds great. Keep us posted with what you find. Thanks
