Many thanks to tkerby and Yeti_Stu for the guidance and photos. Found similar amazing amounts of black crud in the throttle body on our 2013 45000 mile Yeti, cleaning has improved performance and cleared the engine light. Nice simple job - if you have the dexterity of a surgeon, the hands of a small child and the strength of a wrestler! Mark

Thanks for all these useful replies. Anyone care to comment, though, on my intention to power a bypass relay from the unswitched feed to the boot aux socket? I will be using a three way fridge from the aux socket while I'm towing - is this likely to overload it? There also seems to be a live feed to the CD changer at the other side - would this be any better or worse? As you'll gather I'm really reluctant to start playing with the fusebox at the front....

Thanks aladins78, that's helpful, but can you advise if I'd be ok taking the bypass relay feed from the boot aux socket (with a kill switch for when not in use). I do run a three way fridge in the boot from the aux socket while I'm towing. Take your point on the time involved. I did swear I'd never do another after the C Class, and to be fair have paid the pro's for two since. But I'm a bit of a recession victim at the moment..... Actually, I do work in Hertfordshire during the week, so you might not be too far away. I'm being quoted £414 for supply and fit of a swan neck detachable (not sure which make), which is £240 more than buying a Witter detachable and fitting myself. Is it worth a chat? (Not sure of the protocols here re phone numbers etc)

Hi, newbie with late 2006 Octavia Estate for all of two days. Fantastic info on here re towbars (haven't looked for anything else yet.) I'm planning a DIY install, I did a Merc C class a few years ago so don't expect too many problems with the bar itself. I am unsure, though, about the wiring. I only pull a light camping trailer with 7 pin 12N electrics, so do I need either a very expensive vehicle specific kit or a bypass relay? I think I simply scotchlocked a basic kit onto the Merc Canbus rear wiring before, so I'm hoping I can do the same - I really don't want to start pulling out all the interior trim to get to the fusebox. Any advice gratefully received. (Apologies if this has multiple posted - tried to add to a previous topic but didn't seem to work!)
