ordered a full service kit from opie oils for an old audi 2.0tdi everything came correct and no issues with any parts ordered. obviously you put your reg in and select the parts you need but it also comes down to them actually been right to start with based on your reg and opie oils are spot on, everything fitted as it should as it was all correct for the car. they also promise a no leaks when ordering oil or any fluid items and there true to there word 100% packaged very well and arrived in perfect condition. I'd highly recommend opie oils to anyone. my only issue was delivery was a little slow and that was all down to fed ex not opie oils.
