DPF filling up too quickly, EGR sticking, probably the root cause i reckon. Its soaking in Mr Muscle as we speak. The give away for us, was when we turned the engine off and the EGR did its self cleaning process, it sounded like a barn door opening and shutting (No EGR codes have ever appeared). It could be one of many many things - apparently any fault on a PSA diesel that may have an indirect consequence to the DPF or its ability to regen will bring up a DPF message. I’ve just been told my DPF message is due to glow plug(s) failure, apparently during a regen on the 2.2HDi the glow plugs come on. There’s obviously more to regenerating DPFs than squirting diesel into it and setting fire to the soot Share this post Link to post Share on other sites

Mark101 536 Posted February 2, 2019 Looks like I'm having a trip to Gods Country then because you lot are blowing my mind with shit I know nothing about. Though heater plugs were to aid starting from cold only. Share this post Link to post Share on other sites

It's me 615 Posted February 3, 2019 didnt vw invent glow worm module relays to get emissions down? oh not it wasnt them they used other means Share this post Link to post Share on other sites
Dave2302 387 Posted February 4, 2019 Yeah, but VAG were stupid / lazy enough to use that code in a Bosch ECU, which all use the same parameter locations, so even a spotty 12 year old can see what's going on inside a Bosch ECU .......................... Ford on the other hand, on EEC IV onwards would change their PID location addresses every few months, making it a lot harder to spot a bit of code like that As do a lot of other Mfrs .................... VAG was just the tip of the iceberg Plenty others using the same type of code to reduce emissions, they all never got done because it couldn't be proven from their s/w Share this post Link to post Share on other sites

They ran a development version of Bosch s/w under that, the s/w that wouldn't get out of a test cell. When Bosch announced that the R&D s/w version and licensing would be pulled and no longer be supported VAG kicked off. Bosch granted VAG alone, an almost endless agreement on that old s/w and protocol and, with that a confidentiality agreement. .....Bosch knew/had an inkling of what was happening at VAG. Ain't rocket science, other OEMs always wondered how VAG got away with it for so long, the hardware just couldn't do the job of supporting the emissions/mpg/performance triangle. This sounds interesting, Siemens/VDO/Continental must be involved too? The 1.6 tdi is a Siemens ECU and injection system, the 2.0 tdi is Bosch. Share this post Link to post Share on other sites

The good erns voted with their feet. Hit the Nail square on the head there, pay peanuts get moneys lol !! Some of these new Citroens and Volvos, they have all the bells and whistles, but they plain don't work properly due to the inept twat that programmed all the associated modules I'm no programmer, but I could do a better job, but the simple fact is they wouldn't pay me enough, or if the bottom line ££££££'s was right they'd want far too many working hours for it Share this post Link to post Share on other sites
