Hi,

Im wondering if anyone can help me. I have an AUDI A3 2009 plate and since its last trip for its MOT it has been running in limp mode. The main issue is the DPF filter light, The engine management light and also the coil light. Ive heard so much stuff from garages that everything is swirling around in the air and I'm now at my wits end. The initial indication I got was Glow plug 4 was needing changed and shown up on a diagnostic check. I was advised that the car would not regen because this fault was present however the Glow plug was stiff so the garage wouldn't change it in case it snapped.I have had the air mass sensor changed and Ive recently plucked up the courage to take out the glow plug myself which was a success. I have now bought a fairly cheap code reader. The codes I am now getting are:

P246
P2016
P2015
P2196

Clearing the fault codes would not work on my device which was expected. Does anybody have any information to share with me before I spend another load of money for someone just to breath hot air at me?
