Zahnriemen beim SDI abgesprungen!! | Posts 32+

Hello Ingo,

'Personally, I would advise against buying that used engine. If the transmission flange has already broken off, it must have been subjected to significant stress. What if other parts are also slightly bent or have hairline cracks, or if there's bearing damage due to the impact?'
Most likely, the engine hasn't been running since it was damaged, and no one knows how much longer it will last.

Perhaps it's just a 'crazy' idea: Auto Bild has already helped many other car owners whose warranty claims were rejected. How about contacting them once and asking for help? The media have immense power. And if, in the end, you only have to pay for the installation, then it will have been worth it.
If I remember correctly, a Volkswagen dealer once told me that there is a goodwill warranty of 3 years / 100,000 km. Did you buy the car from a Volkswagen dealer?

You don't really know exactly how the workshop justified the request, and why Volkswagen rejected it. I've also experienced situations where different Volkswagen dealerships received different 'goodwill allowances.'

I wouldn't give up so easily if I were you, especially with that much money at stake.

Regards,

Eike.

Hi,

That issue with the engine from the accident is already resolved because the crankshaft is different and the cylinder head doesn't fit either.

I have already sent an email to 'Auto Bild,' but I received an automated reply stating that they only empty their inbox once a day at 9:00 AM. Let's see what their response is.


I tried to call 'Gute Fahrt,' but no one answered the phone.


I will have a report prepared and then send it to Volkswagen in a letter, hoping that they will cover at least part of the cost.
I've heard from several people that they achieved more by sending 'private' letters than a dealer would. It seems the dealers are just brushing them off with something like, 'You know how this works, you're a Volkswagen dealer.'
Let's see what happens.
If VW were to cover the cost of the materials, I would be satisfied. I would pay the labor costs myself, even though that's still quite a bit of money. I'm a student, after all, and chronically broke...


I'm going to have to buy a winter car because there aren't any left this year. (Temporary solution)


The alternative would be to buy a different car (definitely not a VW) if VW doesn't pay anything.

or convert it to a 1.4 TDI or 1.9 TDI engine. I'm not going to get the money back that I spend on repairs anyway, so I might as well spend a little more and convert it to a TDI.




'I find it very disappointing that an engine fails with full maintenance and such low mileage; it can happen, but at 56,000 km? What's even worse is VW's attitude, leaving customers stranded. It seems all they care about is profit anymore; quality no longer matters, which stopped being a priority back with the Golf 2. That's my opinion and experience.'


Best regards,
Ingo

If anyone is still interested, I finally figured out exactly what was broken. To do that, I had to disassemble an engine mount. Luckily, we have a 500 kg crane with a hoist above the lift platform! It would have been very difficult without it.



The tensioner is neither locked nor seized. It can be turned freely and doesn't catch. However, it doesn't maintain its speed after being spun up, which is probably due to the low mileage. The roller rotates in a very 'smooth and even' way; I don't know how else to describe it.


The water pump is rotating, the shaft isn't sheared or jammed – so it's also not the cause of the problem.


The fuel injection pump is rotating; it starts easily, then becomes harder to turn, and after reaching a 'peak,' it becomes easier again. If this is a piston pump, it seems to be in good condition. Is it a piston pump?



Bleibt als Ursache wohl nur eine zu lasche Spannung oder ein Materialfehler am Zahnriemen. Da ich den Zanriemen nun ganz rausbekommen habe, konnte ich ihn genauer betrachten. Also geschliffen hat er offentsichtlich nicht, denn erstens hätte ich das bestimmt gehört und zweitens könnte ich den Aufdruck nicht mehr lesen! Der Aufdruck ist zwar schlecht zu erkennen, aber er ist noch da. ASo, those longitudinal grooves in the belt are probably a manufacturing defect, because the printing is only a few tenths of a millimeter thick and would have been worn away long ago if it had been sanded.
The illegible marking might be due to the water pump, as the smooth side of the timing belt drives the water pump.



Under the valve cover, a shocking sight: all the valves were broken. The surfaces where the camshaft makes contact are completely torn or severely deformed, to the point that you can see the imprint of the cam lobes. Additionally, there are small metal shavings inside, likely from the valve guides.


I submitted the goodwill request today; let's see what happens.
I probably won't hear anything more about that story this year.

Best regards,
Ingo

Hello Ingo,

Is the timing belt sprocket on the crankshaft also tight and not twisted?

Best regards, Rainer.

Hi Rainer,


Okay, so it's definitely there, but whether it's twisted or not, I can't say. You only see the markings once you remove the pulley for the flat ribbed belt, and that was too much work for me. I had to assemble the car and get it out that same evening. By the way, it's a great workout; it was awesome pushing the Polo all by myself over the threshold of the lift.
