They did a scan on Saturday and it showed a misfire on 3 and 4...
Today, i've called them and they say they have another car in for the same reason. Then he says " well, maybe its becuase of your chip ( technical term of course ! ) - I did tell you that the software update could damage the ECU..
Eh ? Is this just VW trying to wriggle ? Revo said there will be no issue with the upgrade, I asked them first..
Also, looking on the 'net, there are loads and loads of issues with this engine...
Any thoughts appreciated
