1998 Volkswagen Jetta Engine cooling Problems

“My 98 Jetta tdi engine blew approximately 11,000 past its warranty. This would be the equivent of 5 months driving at the rates I drive per year. The dealership (av nissan/vw) told me they couldn't find what caused it and that it would require a replacement engine. The dealership told vw of america, a different story then either had been related to me (that the car had been driven with warninglights on & with damage). Unfortunately when talking to vw of a.

I notified the dealer and manufacture and both said it was normal consumption. I have never had or heard of new vehicles using such an amount in so little miles. Also had a problem at 14000 miles with a throttle surge on the morning startups. Tach would read various RPM's while this was occuring. Then when I would start to accelerate slowly the engine would still surge causing the vehicle to buck violently! …”
