• Peugeot 307 2. 0 HDI Xsi 136 - PEUGEOT 307 HDI HOT STALLING? 25 Sep 2012 (Forum)
  After cleaning the fuel out and refilling with fresh fuel the car still would not start, and even after towing to attempt to bump start it still would not start. The Cat was replaced, the injectors were replaced and the DPF filter was cleaned through with a jet wash and then with DPF cleaner. The car still would not start. The EGR valve was a pain to get to but when removed was completely blocked. A new one was fitted and it appeared the problem had been solved.

  Filter tips 26 Sep 2011 (Ask HJ)
  I'd never owned a diesel-engined car before I bought my pre-registered 2005/55 Volvo V70 in March 2006. It's a delight to drive: a real mile-eater, and...

• 2014 Audi A1 1.6 TDI - EGR Fault and Limp Mode 3 Oct 2023 (Forum)
  Anything I can try myself? I've taken it for a good blast, it drives perfectly when the light isn't on; and it completed a DPF regeneration successfully. I just don't understand how one journey it can be fine, then the other not so much...I drove 200 miles without a single issue the other day, but the next day it was terrible.

• Hyundai i30 petrol - Great car except for..... 15 Jun 2019 (Forum)
  And the 'Auto Hold' brake function has to be enabled manually for every journey which is a pain as the parking brake is electronic and my wife forgets to set it at start up. On another note, I traded in a diesel car for the Hyundai as I don't do the miles for a DPF to function effectively. But reading the manual for the Hyundai (petrol) I was surprised to see a reference to the possibility of a 'soot' warning light and advice to drive the car at 2k+ revs for at least 15 minutes!
• Nissan X-trail 1.6 T32 - Exhaust electric throttle control actuator 28 Aug 2018 (Forum)
    (3) Because of the back pressure in exhaust it also helps to increase temperature within exhaust system to increase temperature within catalytic converter and DPF.  (4) Any fault/failure with the Exhaust electric throttle control actuator could have a detrimental effect on other parts of the exhaust/EGR systems. Can anyone confirm if my basic understanding is correct.
• Renault Koleos - Check injection warning but car fine and no errors 7 Mar 2018 (Forum)
  Four weeks ago I filled up with Asda diesel and I got a 'Check Injection System/Emissions' message (with spanner).  Car went into limp mode so I plopped a bottle of Redex DPF cleaner in.  Took car to garage and light went out on the way.  No error codes found once plugged in.  Car was fine for next two weeks. Filled up again at Asda with diesel.  Message comes on again.
• Golf tdi 2009 1.6 - Injector problem 12 Jun 2017 (Forum)
  Mechanics cannot tell me what is wrong and seem to say it needs emission reprogramming even though it has run for 3 months and about 1000 miles since the emissions is recall without any issue. Error light was only engine management and not dpf Any ideas? I do not want to take a faulty car back which a hefty bill for something not running properly when I do a lot of miles and rely on it.
