S-Type R breakdown diagnosis and where to have it sorted

[evand]

Yesterday I drive from London to Weybridge/ Cobham/ Oxshott & Leatherhead to show a friend the area and whilst driving less than 10mph in Leatherhead my 2006 52,000 mile S-Type R suddenly emitted billows of what looked like steam from under the hood on the left side of the car and the console reported coolant as low, albeit engine temp was normal.  Stopped the car, it was clear there was a lot of heat under the hood. Opened the coolant housing, not at max, but not low either, an no pressure from heat buildup.    When restarted the red supercharger light remains on.  Abandoned vehicle and caught a train back to London.

A few questions if I may:

• based on symptoms described, what are thoughts re what's transpired
• given the vehicle is in Leatherhead, where would you recommend I have it taken to, to be seen to

 

Thanks in advance for the help folks.  Not a great first post, but I still really like the car.

Sorted, know what the problem is. Going to take some work to get it fixed.

What was it then?

The infamous valley pipe.  Supercharger has to come off to get to it.

OK. Thanks
