Try avoiding supermarket fuel and see if that helps

Are they that sensitive ??

My Pug 106 was horrid on Tescos petrol but ran great on BP/Shell. My current DCi 100 hates Tescos Diesel but is great on anything else. Worth a try if you're using Tescos etc. might be an easy fix. :approve:

Weird I filled it right up on tesco standard as soon as I got it :/ it runs fine and drives superb only when you boot it do you get the hesitation and popping, ill ring it to near empty and try some v power see if it cures it!

Has any one got any other ideas? Garage said plugs leads and coil was fine

I think it might have the pops and bangs map

I think it just had a standard remap

Always used Shell, other day was low so had to go Tesco, filled it up with about £10 and car started misfiring and flashing EML light so I refilled will shell and haven't had the problem back

Is it worth running redex or something similar though as well?

Had a similar thing happen to my 182 just after I got it. Was fine until I started giving it a bit of stick then it developed a misfire, turns out the spark plugs were breaking down under load, new set of plugs sorted it out. Was a bit daunting at first as you have to split the intake plenum from the manifold to get to the plugs, just followed one of the plug changing guides on here and sorted it.

I had a similar problem with my first 172. Leads had broken up so changed and it sorted it. Also regarding fuel mine hated anything other than shell vpower.
