Passat, manufactured 11/97 (4 wheel alignments in 12 months). Heads broken!

Hello everyone!

I drive a Passat TDI Variant, manufactured in November 1997.

Exactly one year ago, the tie rod ends were replaced at ATU.
to be exchanged.
Unlike VW, ATU offered a 2-year warranty on the cylinder heads.

In January, the car failed the technical inspection.

The movement back and forth is causing a feeling of strain on the heads again. (Just like with every previous defect.)

The car has 235/40 LM alloy wheels. I don't think that's the problem. Otherwise, the vehicle is driven normally. (No off-road ).

I hope to get some advice from you.

Best regards, Gerd.
