Ah bless him...I always find it best to start reading Iftikhar's posts with a smile as you just know it will test you a little bit. :)
If I may....on Iftikhar's behalf.....and most certainly in a friendly manner....no offence intended to Iftikhar at all.
Hi all, had my dpf cleaned not long ago due to driving less and less now.
This morning dashboard Lit up again check vsc etc. Wife was driving, anyway knew straight away - dpf again. Went to Euro Carparts bought Wynnes dpf cleaner and took it on A13 for 15-20 mins. Could feel a slight difference, went up to 60mph, came home and reset ecu by disconnecting battery. All good, at least for now, so decided to sell it. It's on shpock (Gv06zto) and will be on autotrader soon. Had it for 3 yrs, no other problems apart from dpf and calipers which were replaced with new pads/discs and battery. I will be buying is250 now (auto...hopefully).
Hope that helps....I did add the (auto...hopefully) myself.
