£700 for four injectors is actually quite cheap.

why not buy through europarts and get 25 % off? surely it should be cheaper than ebay.

I just used that link to show the approximate value of four genuine VAG injectors to support what the dealer was claiming in post #199.

Just for info - Europarts are selling castrol engine oil with 30% off until sunday - use promo code CASTROL30.

i have fixed my cold start problem on my pd170

it was the remap causing it

hi what was wrong with your remap as im having the same problem with mine after a injector recall was done and a dpf removal and remap thanks

Hi

It is very commom for the secondary pump on the end of the camshaft to let air into the system, my local VW trade centre keeps 2 on the shelve all the time. Check fuel filter if it has oily film on it change pump and filter

Any update on this problem?

Did anyone get to the bottom of it?

Did everyone check rocker clearance, and KW adjustment with Vagcom?

Nope, no one?

Did everyone check rocker clearance, and KW adjustment with Vagcom?

 

Yes and yes. No difference.

I go so frustrated with this issue I sold my vRS.

 

Skoda are aware of this issue, but they don't make the PD170 anymore and have no PD170's still in warranty so have washed their hands of the whole mess.

 

Shame on Skoda UK.

Reseated injectors using new seals and bolts? Any problems with Oil in the Diesel filter housing after?

 

It has to be something they have touched. The car went in fine, and come out with a problem.

 

Maybe the original map isn't suited to the injectors, and a decent tuner could write a map to suit?

 

The reason I ask is I am picking up a cheap 57 plate VRS PD TDI either this weekend or early next week, and it has the same problems...

I also have a PD 170 from 2007 with similar issues:

 - Struggles to start but starts fine everytime.

 - White smoke after 30 secs to 1min idling (not always)

 - Strong smell (oil/diesel)

 

From the many posts i've read it's related with injector seals and bolts and injectors being correctly placed and tightened.

Did anyone from this post solved this, besides 'amk2vr6' ? 

 

Thanks!!

 

For me changing the exhaust cam timing seems to help with cold starting.

 

It was set too far one side and had to turn quite a bit before starting, gave poor mpg but drove really nice (strong) and didn't seem to regen all the time.

 

I've moved it slightly (cannot seem to get it spot on) it now starts properly, mpg has gone right up (50mpg on a good trip) but it's getting lumpy again when warm (now and again) and also seems to regen more.

 

Probably never worked right after having the injectors swapped, but I couldn't tell as I didn't own the car then.
