Hi all,
Just had a quick search but posts are quite old.

I have a w220 05 plate and have intermittant ignition problems. Key always turns but sometime no final ignition unless I wiggle the key, sometimes and this is the fun part. Whilst driving I lose power and have to tap/ wiggle key and off we go again. Much fun on a motorway when that happens. Anyone had this? I read a lot about people not being able to turn thier key but not loss off ignition. Anyone in derbyshire/Yorkshire that come recommended to fix this issue that wont spank the bank too much?
Thanks in advance
 
Sounds like you are on the right track by tapping/wiggling the key for it to wake up again.

If no fault codes are showing, you could try cloning your current EIS to a used one and give that a shot. I remember paying approx. £100 for a cloning service. I sourced a used EIS from eBay.

Loads of used EIS on eBay, just look for the right part number.
