So I had the 7 year service done the other day where they change all the belts etc. while there I got them to investigate the oil leak that was picked up on the MOT. It was the pinion seal as everyone one here was saying. Got the service done at JAS so they contacted WD on my behalf and they have agreed to pay or the repairs. I don’t see how they could have wriggled out of not paying to be honest but I’m very happy it’s getting repaired and paid for by WD (apart from my £150 excess obviously)
