Comment on Dyno/Compare Yours. Sick 2006 V 2.0 TDI

[CJ_DT]

Hello Guys, thanks for the advice. At this stage it appears that I have reached a stalemate. I dont think it can be timing, has been checked by 3 different mechanics who say it is all fine, unless in the crash a dowel or something could have sheared or broken, but seems unlikely.

Insurance company is saying has spoken to the Dyno operator, who says its perfect, apparently when a workshop manual states peak torque betweel 1750 and 2500, that means that the torque just has to peak in this area, not be maintained........

Its either a case of the worlds least competent dyno operator, or someone who is happy to say whatever the insurance company wants them to say.

Ill let you know if there is any progress.

did you read the article and specifically ask about the camshaft gear? it doesnt matter if all the locking tools are used if the person who times the engine has never been taught to adjust the cam gear. its vital to the correct function of the engine.

[Julian Edgar]

The author of that article took it upon himself to make those changes on the advice of several of the more knowledgeable folks on this forum who also diagnosed the issue for him.
I commented on the lack of proper citation in another thread but the good folks who provided all the know how were content to have helped.

Actually, that's not really true so I wish you would stop stating it.

Where did anyone advise me to alter the timing myself at home and prove the results by road testing? No where.

Where in the thread you quote is the description of the PD system, and my interpretation of the results of incorrect cam timing with that system - material that I used in the article? No where.

In fact, my memory is that what I gained from the thread you cite was the information that the factory provides the ability to adjust the cam timing by small increments. That was good information, too. But to imply the the thread was my sole source of information, or that what I did was directly suggested in the thread, are both wrong.

However, more important to the OP is that what I did doesn't seem to me to be the answer to his problem (because my car still had plenty of 'go' - it was just moved within the rev range.)

The OP's car is a 2.0L, 16V. I can't say that it is more sensitive than the 1.9L 8V engine, but I'm sure its possible.

But, I don't think that anybody touched the timing belt in the OP's engine?

I thought it might be possible, depending on the damage to the vehicle.... or even some crash debris get caught under the timing belt and cause the timing to jump a tooth - i've seen this before. I know of a case where a person hit a bird at 120km/h, parts of the bird and the radiator grill got under the timing belt and the injector pump jumped a tooth - all the timing covers were fitted to the engine aswell.

I know that the weird things happen in the accidents even the minor one, but he didn't mention that. If they did change the t/b, then there would be a good chance that someone didn't follow the instructions on how to replace it. But if the t/b cover, crankshaft pulley and engine mounts are untouched there is only a very slim chance that the timing is the culprit.

Hopefully he keeps us informed what was the fix.

Having read the article, its got me almost keen enough to get the car back from the repairer and have a play, but figure as soon as I start playing with it I am on my own.

I know when the original mechanic was looking at it he said the timing cover had been off the engine before, thats what made him suspect timing, but since then an independant VW mechanic and Solitaire have both checked timing, surely its not that hard to get right.... Timing belt has not been replaced to my knowledge. It was one of the few things not on the itemised crash shop bill, and they billed for everything, even things they didnt do.

Next step I think is off to Adelaide Fuel Injection, they have been recommended as the next port of call, but seeing as its the insurance company dealing with it, it could be difficult (they chose the original dyno). And rest assured if and when I ever get this fixed up, I shall let you know what the issue was.

That said, when/if the insurance company finally get it running right, they still need to get my headlights and bonnet pointing in the right direction. As much as I am into nature, I would prefer the lights to be on the road, not possum hunting in the trees on the far side of the road.

Looks way down on power in the bottom end to me especially given the mode use and the dyno type, yeah not good at all . Find another place to dyno the thing at and then you'll know if the first place did it correctly. If they did then at least you'll have something concrete for Adelaide Fuel injection. Actually S&J down there have a mainline I'm pretty sure and they do many cars. Log everything with vagcom during the run.

Hello,

Still struggling away with the insurance company....

At this stage it appears I need to find a 2006 VW golf 2.0 TDI in adeliade to go on the exact same dyno. Anybody in adelaide got the same model and some spare time, I will pay for the Dyno run, and reimburse you with a suitable amount of cash for your time?

Any takers. Thanks
Chris

Well looking back at the originalthey've used the dyno shootout mode 81 ehich if I'm not mistaken is the locked/fixed mode with a ramp rate suitable for Big HP V8s. I think they should be using 4F for 4 cyl forced induction 44 is awd.

Here's a run that I did a while back on a 103TDI before and after a remap. Its a bad example because in the plot I've used the run starts at 3K(Doh!!) - normally what you might do with a petrol. Disregarding that part or the run the rest gives you an idea of what you will typically see on a Mainline. I will add though that its very hard to get the low end of the run off boost to do the ramp as the DSG box just keeps wanting to shift down a gear. They just have a very flat torque curve compared to a petrol and you could pretty much draw that line out to the left and be close to the values. I will replace that with a better one one day.





Usually I would be the first to say the mainlines always read lower and in some cases much lower than the dyno dynamics runs however in this case I don't know what the shootout mode shoot 81 is doing to things. It could really be the totally incorrect mode to be using. If in fact if it is the correct mode then something just aint right at all

Please do yourself a favour, end you pain and independently go to S&J and at least you'll know if its really crap or not you should see very similar results to my one here`

Well it turns out it may remain one of lifes mysteries. Insurance company finally gave up on Solitaire, and have agreed to write the car off. Bit disappointed because in my mind I am sure it couldnt have been anything that major, but glad that this 14 month ordeal is almost over.

Guess its time to start shopping again, anyone got a golf V or VI diesel that they want to sell?

My daughter is getting Tiguan soon and we will be selling Golf, it's done only 45,000km. Pm me if you like.
