Hi just had my 2009 2.0 TDI in at a halfords autocentre for a air con recharge and got them to do a diagnostics check while it was in. Had the DPF sign come on a while a go, it went into limp mode for a bit. Next day went for a blast round motorway symbol went off but now the emmisions light has stayed on since. Only fault said DPF Blocked. I mentioned a possible sensor fault cos ive heard that being common, but he seemed to rule that out. He said the can take the DPF off the car and leave it in some kind of solution overnight to help clean the DPF then force a regen the next day for £180. I've had it in a few times for little bits an he's normally pretty good so im happy enough that hes not bull****ting me. Anyone had this done?? I am tempted to jus get it removed and remapped but still got a warranty from when i got the car (DPF not covered) so didnt fancy affecting that. Could do without spending the £500 for removal/remap too. Jus wondered if anyone has had any experience with DPF cleaner?? I know you can get these ones for £20 but cant see that doing much. Thanks anyway in advance i know theres loads of DPF threads on here just not seen one about cleaning them.
