The only thing I've done is to run the car on Shell Vpower with a shot of Millers additive (overkill maybe !)
The result is no smoke when warming up - at all !
I've still got the rough idle but that'll do me for the moment
Yes I've got that as well with my avant 170, there's a thread further down the list. Could possibly be cam timing out by a few degrees as suggested by various people.
Have you got access to vcds ?
Is so, post up your torsion value from group 4 measuring blocks, it should be 0 deg +/- 1deg...
Its seems to be a pretty common issue, I'm hoping someone will come along with a fix for their problems
I think the first thing to address is the torsion value, anyone got some advice on adjusting this ?
My car is a 2008 BRD 170 TDI, 130k miles. I've got the usual rough running and smoke whilst warming up that seems to crop up.
The egr and manifold have been cleaned in the last 2000 miles and injectors were replaced in July 2013
When the car starts and warmed up its fine, its the bit in between...
I wouldn't believe what that article says really, diesels don't have a throttle butterfly like petrol engines, they always run with an excess of air and don't create much manifold vacuum at all (if any!). The throttle controls the amount of diesel fuel injected only. The egr valve introduces...
Yes I used the Triple QX oil, I'd had great sucess with the slick 50 in mk2 Golf GTI's 'back in the day', I guess I've learnt the hard way that it's no good in 'our' 'boxes !
Hopefully changing it over won't have caused any issues
Changed the gearbox oil today on my 170 TDI fwd after 130k miles, maintenance really but hopefully to cure a notchy 1st-2nd gear change. I used 75 w90 fully synthetic box oil from eurocarparts with slick 50 additive which I've had good results on other cars. Went for a drive and the change up...
Personally I like my 170 tdi avant, 32-34mpg cold runs around the doors and around 44-46 mpg on a run at motorway speeds (brim to brim calculations). Tank mileage varies from 500 to around 700 so it's not as bad as people make out. My injectors were new last July and the egr and inlet manifoild...
