It’s back, well before Christmas so thanks to Cassley Autocare of Cardiff, great service. All done within a week, unlike the other two places that quoted me mid Jan.
The car is definitely quieter than it was originally. The leak may have been there from the start slightly, as it had sounded ever so slightly whooshy before at times. It doesn’t feel any quicker than it did originally, really, but it may be a touch more economical. And the transmission is now much smoother, which makes sense because if the transmission was expecting the engine to be producing more torque than it actually was it wouldn’t have been able to shift properly.
However given that I can’t imagine life without jobs to do on the car, I still have two. One is to fit the Alexa Auto thing so I can have full music access whilst driving, the other is to try and get what I think is an ink stain out of the expensively AMG branded passenger side floor mat.
