Marshall Skoda Reading

My car was booked for a Haldex oil change. They also carry out a "safety check" each time the car is with them and I was glad of this as the car was making noises from the rear. When the car was returned I was told I needed three replacement wipers as they were juddering. I said to the service member lets go and check as I drove 950 miles in the last three days and they were fine. She looked shocked and said she could only pass on what the technician said, there was nothing else noticed during the check. Yesterday my car was in MOTEST for a service and MOT and a broken rear suspension spring was found. So much for the Marshal Skoda safety check
