For the timing change, the injection pump gear and camshaft are fixed in place, so why can anything then become misaligned?

Timing belt tolerances! I've always had to readjust them until now (this was also the case with the TD models).

@Rainer, What kind of screws could it be that might be stuck? You really don't have to solve that many.

Although I'm not Rainer, I once had the nuts of the ESP (in the front console) get stuck , and when loosening the ESP lines, the pressure valve (ESP) can come loose -> in principle, you should use HAZET wrenches to counteract this.

The Allen screws on the ribbed pulley were extremely tight and difficult to remove.
After a lot of trying, I managed to loosen one screw using a small socket wrench and an Allen key. With the other one, I was forced to drill off the head. To do this, I had to remove the wheel because I couldn't get my drill in the right position otherwise.
"For €75, I wouldn't get my hands dirty as a mechanic. The responsibility when replacing the timing belt is significant. What would you say to your mechanic if the new timing belt breaks or jumps time after only 2000 km?"
It's better to take a little more time, properly secure the camshaft, and work carefully.
The €100 saved is no match for a ruined engine because it had to be rushed.
If the power steering reservoir needs to be removed, it's almost impossible to avoid spilling a little bit. Since there is very little fluid in the reservoir, some will need to be added afterward. So, don't be surprised if the power steering makes noises (and sucks in air) after the timing belt replacement.

Best regards, Rainer.

Hello Rainer,
According to my Bosch repair manual, the total time required for a belt replacement on an Audi 80 TDI is 1.90 hours.
For an A4, the price is €2.90 per hour, and for an A6 (1997 onwards), it's even €3.50 per hour because parts like the bumper need to be removed.

The servo reservoir is located on the far right side, so it won't be in the way.

If it takes him a maximum of 3 hours, that's still €25 per hour. That's quite a good side income (without any calculations, of course).

I'm hoping for the best and will let you know how it goes.

The instructions for the Golf4 and A3 models with the AHF specify:

Quote:

The time specified by Volkswagen for replacing the timing belt is approximately 3.3 hours.

With the tricks mentioned here, the amount of time required can be reduced by about an hour.
It looks like I have the wrong car... the A4 is supposed to be faster! }

Hi,

Okay, to be honest: do you think these time estimates are realistically achievable ? A timing belt failure at the fifth ( ) position in the accident statistics must have a cause. In such a short time, this can only result from shoddy workmanship. Most screws must be loosened with manually operated tools, or are there potential time savings through pneumatic impact wrenches ?

Hi Christian,

I wouldn't remove the camshaft gear, cylinder head cover, or vacuum pump anymore; a marking on the camshaft gear should be sufficient.
It only works if the new timing belt is not significantly longer or shorter than the old one. Otherwise, you'll have to reach into the toilet bowl because then the camshaft wheel has to be removed, and the fuel injection pump wheel also needs to be loosened.
If you don't remove the vacuum pump, you also don't have to remove the glow plug auxiliary heater. This prevents coolant from leaking out, so you can avoid having to top it up.
With the right pliers, those crimp clamps shouldn't be too much of a problem. But why should I buy one when hose clamps work better anyway? The VW/Audi workshop will definitely have a suitable pair of pliers.

It all depends on how different the old and new versions are, and what tools are already available.

Therefore, under favorable conditions, the specified time can be halved, but it can also be quickly exceeded under unfavorable conditions.

In my first attempt, including extensive customer service, an oil change with filter, air filter replacement, cleaning of the air intake box and pollen filter, centering of the ribbed belt pulley, and the construction of special tools, it took me a full 2 days.
Meanwhile, it should work within the next 2.5 hours. Hopefully, the engine will last long enough that I'll need all this stuff again...

Best regards, Rainer.

Sure, here's the translation:

'Hi there,' or 'Hello.'
Okay, the belt has now been replaced. It took him about 4 hours to do it.
He's not exactly someone I would describe as a TDI expert, but the important thing is that the belt is new.
He didn't adjust it using a dial indicator or VAG-Com.
He never did that, and all the engines always ran perfectly well.

The engine is running normally, starts easily, and has power.

What benefit would I get from having the valve timing checked right now?
Will it then run better? Will it consume less, or what ?

Thank you very much in advance.
Best regards,

a clear conscience.
Im Ernst, bevor Du bei kaltem Motor oder was auch immer Startschwierigkeiten bekommst oder der Motor wegen zu frühem Einspritzbeginn ständig unnötig belastet wird, kann eine Kontrolle ja nicht schaden? GeSure thing.

Best regards, Rainer.

Hello,
It seems like I'm already having a problem!
Since I changed the belt, I've noticed a slightly higher engine temperature. It used to be around 90°C, but now it's a bit above that.

Is it actually possible that the injection timing is too early, which puts more strain on the engine?
I'm not really keen on going to Audi just to hand them my money.
The workshop where my parents take their cars for repairs only uses a dial gauge, which isn't supposed to be very accurate.
Can anyone recommend someone who offers this service affordably in the Kiel-Rendsburg area?

Have a good evening.
Best regards,

Sure, here is the translation of the text from German to English:

"Hi,"

It's possible that your assumption is correct.

Forget about using a protractor. It's a waste of time.

If necessary, use Ulf's method as described in the article.
/viewtopic.php?t=3195
If you don't want to go to an Audi dealership, any Seat/VW/Bosch workshop should be able to check and adjust it.
A check of the fuel injection timing should cost a maximum of 5 euros for the coffee fund and takes 1 minute (assuming the diagnostic device doesn't take 3 minutes to boot up).

Best regards, Rainer.

Hello,
I was just at a Volkswagen dealership. A mechanic used the VAG-Com diagnostic tool to read the fuel injection timing. It was reading quite well.

Perhaps the voltage regulator in the instrument cluster is faulty, which could cause the temperature gauge to display a higher reading than actual.
Let's see.

Best regards,

Hello!
How about engines that have been chipped? Don't they display incorrect values for the injection timing, which are then 'corrected'?

Greetings, PaKubi.

No. The technical article on ESP (Electronic Stability Program) settings also explicitly states the conditions under which the injection start is measured.
