I've kept a low profile after i did something pretty stupid, turns out many people to it. I filled my Edition 30 up with diesel and drove about 5 mile till all hell broke loose and the car died.
After a 20 minute tirade of verbal abuse aimed at myself I calmed down and called the AA, they took me to a VW main dealer in Leeds and they fixed my car - replaced fuel filter, changed speak plugs and flushed the fuel lines, in all almost £350. Ouch.
I thought all was well but deep down had a feeling i might have damaged my CAT.
A couple of months later I took it to R-Tech for a stage 1 remap, the graph suggested 295bhp and I was more than happy with that but Nick said there was an error and said is should be delivering more power, at that point I came clean with my fuel mix up. Nick said the CAT might be damaged from unburnt diesel and gave me a used down pipe with the pre cat removed. Thanks Nick, much appreciated.
Recently the car is been pretty poor both performance wise and economy, so I asked for some diagnosis help and GTI-Andy stepped forward, a boost error and cat error was showing.
I've took my time but eventually had the exhaust replaced today and boy what a difference!! I haven't had a diagnostic re-run but it feels amazing and sounds great.
Thanks again Nick and thanks GTI-Andy.
I check the colour of the fuel pump 5 times before putting the nozzle into the tank now!

Ouch mate, glad it worked out ok
I know people who have put petrol in a diesel, that's is seriaously damaging and expensive, fuel pumps, lines, injectors, seals erc etc are all junked
