Check your fuel cap. Is220d

[Scouselexus]

Bought is220d in Feb. Have had constant battle with the vsc eml triangle Xmas light display on and off for months. Had the egr cleaned, used lots of dpf cleaner, serviced with Mobil 1 fully synth oil. Longest lights stayed off was for three months. 

Now they are back, even mainly motorway driving hasn't cured it. I checked my fuel cap, cleaned it and the filler neck. Guess what? It clicked when locked left it few seconds and it clicked open again. Who notices it you just fuel up lock and go. 

Next time you get a chance just check your cap is staying locked might be causing someone a vsc eml lightest.

went and got a replacement cap. Fitted it hey presto lights out. Had good drive on motorway as usual and five minutes from home vsc eml again.

the car never goes into limp mode either so assuming not a serious fault. Just want it to go bang so can justify to swmbo to get nice is250 auto
