so my sister goes to the garage, it turns out theres an complete extra set of 4 locking wheel nuts on both off side wheels, as well as the original set. so 3 locking nuts on off side front and 3 locking nuts on off side back, for which she didnt have the key. the garage obviously said they have never seen this before and considering the hassle I had with the supplying dealer (Citygate) upon purchase 4 years ago, I am not surprised. so they took off the offending nuts with the master and she brought new normal nuts to replace them. then the service reception kicked up a fuss saying they arent insured to put nuts on a wheels (workshop was busy), they relented in the end and put them on.
The new dealer (not supplying) claims when they serviced the car over the past 2 years, they never took the wheels off. However the brake fluid was changed and surely you need to take the wheels off to bleed them?
all in all a complete pain in the neck, probably a total one off, but please everyone check you dont have extra locking nuts on your car, as you could be screwed if you break down!
