Small update. It was remapped but due to some hunting issues this had to be overwritten when the dealer did a PCM update with the latest software, it needed this anyway as it was the original version but the real reason for the hunting was never really traced as there were no codes, and after the update and a fuel filter change all was well, until a couple of weeks ago!
I had been driving it hard and noticed when i stopped that the idle was a bit more clattery and tinny than normal, again no codes, no drop in performance and ran fine otherwise?
Anyway it seemed to get better but the dodgy idle didnt go completely. It seems strange this only started again since i put Esso fuel in! The first time it had issues was when i used Tesco?! All inbetween i've been using mainly Shell and its been fine, lets not blame the fuel though..
Yesterday i ran the tank low, put a dose of Millers in and drove it as normal, for the first time since i've had it the visible smoke had dropped, which is odd as on and off, i've been using various injector cleaners since purchase.
It was due a EGR and inlet manifold clean so last night i stripped it all down and was most disapointed, it was very clean! The MAF sensor was already getting dirty again after just 3000 miles since the last clean, the manifold just had a film of soot, as opposed to being 50% blocked like my old Tddi was..
Likewise the EGR itself was in good shape and it was only the area where the MAF sits and the EGR pipe meet, where there was any build up of crap,
Put it all back this morning, took me 30 minutes, well i am a mechanic
, i also disconnected the battery for an hour to reset the PCM adaptive parameters , gave it a 8 miles drive and its perfect now, idles like a new van, i didnt notice any smoke at all which is a big relief as its always been a bit excessive for a standard van.
I'll give it another couple of hundred miles and then get the map back on.
Fuel economy has been very good, its never dropped below 35mpg and regularly sits around 40mpg, it is a bit slow compared to what i'm used to though but its pleasant enough.
Last pics show the LED sidelights that were donated to me, matches better with the uprated headlight bulbs.
As the manifold was very clean after 63k, the only reason i would consider removing it, would be to improve performance and economy/emissions. Its very clean now so now point at the moment.
