I have a UK 1989 300se, I have just spend £1,200 on a service, and as you would expect it has been running fine. It has 134,000 miles and idles smoothly and runs very well.
Today I was approaching a traffic island, as I slowed down, my car just died and I ended up in heavy traffic with poor steering and braking.
I started the engine again, it was idling smoothly and seemed fine. I drove down a 3 mile road at about 60mph, slowed down to get onto another traffic island and it died again.
I'm really confused! Any help appreciated.
