2.0 TDI (BKD Engine) Cold start problem...Getting frustrated now!

[andybon]

I've had this problem since I got the car and no mater what I do, It will not go away!

Here is a video of the problem.

Basically when it has been left stood for either the day on the works car park, Or overnight this is how it starts from cold.

So far I have replaced

• Fuel Filter, oil filter, air filter
• New battery with the correct cold cranking amps (Bosch silver one)
• Fuel/coolant temp sensors
• Serviced using correct oil grade/type(Castrol edge 5/30 fully synthetic)
• New timing belt and water pump with the timing checked using the pins and VCDS
• New starter motor
• Charge cooler pipe
• EGR valve and EGR system clean out
• New glow plugs (Replaced with BOSCH items)

Its driving me mad at the minute! Seems i'm throwing good money after bad and nothing is working!

Has anyone had a similar problem and if so what cured it?

Is it not the injector loom that needs replacing to sort this?

[Trekmeister]

Just out of curiosity does it kick blue smoke out when initially started. If my car is stood it can occasionally present to a lesser degree a similar sort of start up with a puff of blue smoke very briefly. I've come to the conclusion mine could be valve stems (If its used for the rest of the day no smoke at all). Ive also found my car prefers to run on BP ultimate and starts and runs so much better using that over anything else including Shell V power.

There is a slight puff of smoke but nothing bad, Plus it doesn't use any oil at all which sort of puts valve stem seals out of the question.

Does it use water?

[andybon]

Doesn't use any water at all, Coolant was changed with the timing belt and water pump and it still looks clean.

PCV ... Injectors...

[andybon]

pcv?

[Scottymon]

I only say that because I've recently upgraded the pcv on an old freelander, was blocked and shooting oil back through the intake/egr bit of a mess.  It had terrible cold start problems... Now its replaced and all cleaned up, it starts every time first time... And runs a lot better.

Does the VAG TDI not have a PCV?

[Scottymon]

Also a lot of the freebies blank their EGR completely... For better economy and running...

I had this problem and it was faulty glow plugs

[marko]

glowplugs or ignition timing imo...although unlikely to be glowplugs as they arent required as much as way back with more simple diesel engines..
pump timing can be checked on vcds...block 44 is i remember correctly

Could be the fuel pump

[andybon]

I've been thinking the timing, What should I be looking for on VCDS, Just need to find somewhere local who doesn't cost a bomb to do it, Spent way too much these last few weeks!
