I own a skoda superb 2.0 Tdi. I am facing white smoke on startup after timing belt change. The smoke starts after 5 minutes of tirning on the engine before that it runs perfectly fine. Is there any way i can check and adjust my tdi fuel timing in vcds . The vehicle is equipped with UDS protocol so the measuring block option is greyed out in engine group.I am also posting a full scan of the vehicle

What your asking to do is re-map the engine I don't believe you can do this with VCDS.

 

Your engine code is CLJA 140bhp ? Did you time the fuel pump correctly? 

 

You didn't have this problem before changing the timing belt ?

No i did not have this problem before timing belt. Yes the engine is CLJA 140 bhp. I wasnt asking to remap just to see the tdi timing graph on vcds to make out if the timing is out. Can we time the fuel pump on this engine? What i heard the cp4 is  electronically controlled by the ecu and cannot be adjusted manually. 

I have just changed the timing belt on my 2.0 CFGB 170bhp  engine which has to have the fuel pump timed which is on the far right of the photo.

 

It uses the same timing belt kit listed as the CLJA engine so I assume you have a belt driven fuel pump?

 Can you help me how to time the fuel pump. Would be great help.

Does engine looks the same as mine?

Yes the engine looks exactly the same

The fuel pump is belt driven on the CLJA engine as well

The fuel pump has to be timed. It's not as critical as the crank and cam shaft timing but it has to be fairly close. I'll see if I can find the Autodata print out I used.

Ok thanks also do tell me how to time the pump as in manually adjust the fuel pump or in vcds. The crank and cam shaft were both locked in place using special tools.

 I had also locked the pump pulley in place just as mentioned in the picture above using locking pin. I thought you are mentioning retarding it forward or backward after loosening the 3 bolts holding the fuel pump pulley in place. Can that be done because i feel my pump has advanced timing

It's difficult to see the fuel pump timing slot with the belt in-place. The reason for undoing the cam shaft and pump pulley bolts are so that the cam belt tension can be set correctly between the two pulleys and all the belt slack can be taken up by timing belt tensioner. The cam shaft and fuel pumps should be locked with the timing pins so their timing remains correct. 

 

I don't see how changing the cam belt can have affected the ECU fuel pump settings ?

The cam shaft and fuel pumps should be locked with the timing pins so their timing remains correct. 

 

I don't see how changing the cam belt can have affected the ECU fuel pump settings ? 

 That is what is bugging me. Even after following all the steps this problem has occurred. I just hope the fuel pump isnt going bad. Any way to check the timing om vcds for these engines?

Not that I'm aware of ? I had no problems after changing my belt.

 

If there was an issue with the fuel pump then I would have thought VCDS would have given an error code for fuel rail pressure ? White smoke does sounds like it's over fueling ?

Yes and it stops completely once the engine has warmed up. 

I know it's a PITA but I'd be inclined to manually check the belt timing again.

 

When the fuel pumps fail the bearings start to break up and you will find metal filling in the fuel filter and also in the top of the fuel pump if you remove the fuel pressure regulator in the top of the fuel pump. Though I would have thought a failing pump would cause low fuel pressure problems ?

Already checked the regulator and filter for metal shavings they were not present. Rechecked the timing also and it was ok. Could be a faulty or leaky injector?

Yes that's a possibility. But to find that out you'll have to take them off the vehicle and have them tested. I got charged £25 per injector and then I had to change all 4 on mine not cheap !  Though my issue wasn't over fueling. The injectors were leaking back and causing low fuel rail pressure.

 

Maybe this issue existed before you changed the timing belt and hadn't noticed? You only started looking after you'd changed the cam belt?

 Will get them checked. I just hope they can be refurbished at bosch

I don't know if your engine has the same injectors as mine? I exchange mine at my local diesel specialist as they have to send them away to be re-manufactured, cost me £840!

I have the exact same injector with same part Number. They cost 900 pounds here for the new ones

 From what I've read they are very prone to failing! I believe my car has had the injectors changed before as there are chatter marks on the injector sealing faces down inside the cylinder head. It took me ages to polish the marks away.

 

I bought my car cheap with a declared unknown engine problem It was the injectors. As I'm wanting to keep the car I decided not to gamble with trying 2nd injectors as they fail regularly there are a lot used ones out there and i wonder how long they will last ?

I've been thinking are you sure this white smoke is not just normal condensation coming  from the exhaust until the engine has started to warm up?🤔
