If a repair shop did the cleaning & tested
some how to tell you that,then the injectors
have to come out & be ultra sonic cleaned
Fairly new vehicle for those issues
Try a different shop
The only reason to replace the fuel pump was
if it failed completely
Car is too new to need spark plug wires,was the ignition
system even tested & was fuel pressure tested?
Have to look at fuel trim on a scan tool also.

SOURCE: cold start valve problem

if you have an electric cold start valve make sure to unplug it and if keeps apling fuel with electrical conector unpluged that means the valve is not good, but if not then you have an electronic problem, possible a bad cold start sensor or cold start module or cicuit problem, and might be a time to take it to an electrical shop

SOURCE: Hard start when cold, running rich, poor fuel economy

Chrysler has a bulletin out for a simular condititon that involves replacing the pcm. Heres the bulletin number 18-005-04. This is only 1 possible cause , Fuel pressure, coolant temp sensor, thottle position sensor all can cause like problems. Seeing sensor values and fuel adaptives with a scan tool helps pin point problems.

SOURCE: '95 Honda Civic EX will not start after cleaning fuel injectors

I would talk to who cleaned the injectors, I don't know if it something they did or not. It could be a stuck open injector. The exhaust would have a raw fuel odor if it was. What it sounds like is a blown headgasket, which can just happen. The exhaust would have a sweet smell to it. Usually starts as a small leak (between cyl. 2 & 3), the engine burns the coolant while driving which you don't see. Then the coolant level gradually drops to a point where the car overheats, which warps the head, causing a large leak. Now you see the coolant burning (white smoke).
Good luck Honda Al

SOURCE: 2000 TDI - Lots of white smoke at cold start.

Sounds like your injection pump timing is off, an injector is leaking or a bad seal on your IP.
VW dealers have a horrible reputation when it comes to TDI's. Check out the posts over at www.tdiclub.com Those guys are very knowledgeable - and the first thing they'll tell you is don't take it to a dealer.
You can probably find someone in your area that has a copy of Vag-Com (scantool software that vw uses) software that could look at your timing. It definitely sounds like your dealer was throwing parts at your car because they didn't know what your problem is. If I were you, I'd copy and paste your post from here over at www.tdiclub.com

You need to have the dealer look at this, if you fool around with it you can void your warranty. Toyota looks for any legal excuse to void the warranty.

Make sure your fans are running. It sounds like your fans are not working all the time. With the AC on the fans should run constantly. Check fan relays and fuses.

Shut off daytime running lights?


You can't disable them it's illegal. If you need to shut them off while the engine runs say at drive-in, apply the parking brake (this works on some but not all cars, and don't try driving with parking brake engaged just one click).
