2006 SL 500 misfiring ?

[Bieldside]

I have a lovely SL500 with about 46000 miles
Just serviced by MB Guildford with no issues
Came back the 100 miles to home from Cambridge at a fair pace
No problems until I was 1/2 mile from home and the car seemed to start missing a beat
Took it out on Saturday and it seems to be fine running but once I slow down it gives the impression of misfiring - or juddering
Thoughts ???

Did you refuel at any stage? If not then might be electric related ie coils/maf etc but I don't have specific knowledge of the model and engine

if it ran fine going to dealer could it be something linked to service?
What did service consist of: Plugs air filter etc
Connector come loose? have you opened bonnet and checked around engine?

Next move is plug into star or take it back? if you do be prepared for it being nothing they have done and new bill!! Unless you are a very good customer.

Or take it to recommended local indy? which is what I would do.
