you implied it...
Timing belts are not in the same league as a cabin air filter... if the manufacturer calls for timing belt replacement at 90k - and you decide it’s wiser to solicit a second opinion - what type of mechanic is gonna tell you to blow timing belt service off?
not sure what you’re driving - but if you happen to have a DSG - i would not defer on the factory recommended the tranny service or deviate from the intervals ...
the “seasonal” A/C service solicitation is worthy of consumer scorn ... i would have pepper-sprayed the service agent
thank you for telling me what I implied. Appreciate the accountability.
