Volkswagen Tiguan Vibration on Acceleration

Vehicle: 2015 Volkswagen Tiguan AWD, Odometer 160,000km.

Symptoms: Vibration on light acceleration from a stop, kind of wobble side to side motion of vehicle. Vibration is felt throughout the car, especially on front seats and is present only under load. No vibration on steering wheel and no vibration on high speed. Also, no vibrations when vehicle is not under load (ie, accelerator pedal is not pressed).

Diagnostic: Front CV Axle failure (leaking grease from left front axle but no symptoms on right axle) and transmission mount. Transmission mount was replaced with a new original VW part. Both front CV axles were replaced with aftermarket parts. Vibrations persisted just the same, almost no changes after replacing front CV axles and transmission mount.

Left and right front CV axles were replaced again, this time with a different aftermarket brand. Vibrations again stayed constant with very little changes, if any at all.

Volkswagen Tiguan Vibration on Acceleration – Solution: Front CV axles replaced with original Volkswagen parts. Vibrations disappeared and vehicle runs and drives fine. These cars do not like aftermarket CV axles. Quality of aftermarket axles is not on par with Volkswagen specifications and will cause vibrations on acceleration and under load. All aftermarket parts are more or less the same, recommended specifications are far off from OEM.

If you have a similar problem, before chasing your own tail with aftermarket axles you should install only Volkswagen original CV axles. While Volkswagen axles are at least triple the price of aftermarket ones, experimenting with aftermarket axles will be waste of time and money in labour which will cost more in the end.

In any case, same goes for other Volkswagen and Audi cars or SUV, this issue with aftermarket axles in not limited only to Tiguan.
