Unfortunately I can't recommend Thrulow Nunn for servicing or repairs. I sent my car in recently after experiencing some electrical issues. They charged me £260 for 2 hours of running diagnostics to find nothing. In the pre-service description I mentioned I believed it may be a battery issue. They told me if the issue persisted in the next 3 months to get in touch and they would look at it again free of charge. The issue did crop up again, my partner took the car to another garage to get the battery tested and low and behold I simply need a new one. When calling Thurlow Nunn to see if any of this would be covered by them the man I spoke to was incredibly defensive and rude. I would suggest you go elsewhere if you're experiencing issues with your car or you run the risk of spending hundreds of pounds to simply sort the issue yourself!
