Volkswagen Tiguan parts reviews

Have a 2021 Tiguan SEL with Pirelli Scorpion tires, 29,000 miles and the tires are still "green" for tread. Probably get 45,000 out of these.

I have Cooper Endeavor Plus tires on my Tiguan. They also are a LOT quieter than the OEM Hankooks that were on it.

Went with the new Pirelli Scorpion AS Plus 3. Seem to have decent ratings but it’s a brand new tire so time will tell I suppose. Only thing I can say right now is that they are much quieter than the original tires were. The Goodyears were obnoxiously loud at 90km/hr or higher.

I run them on my Tiguan and they’re working out well for the past 3 years although they’re also not a left and right set.

I would change my own cabin filter...seems EZ breezy....

I would recommend only OE VW or Mann filters with a VW 502 oil, preferably 5W40.

You have to lookup the valve online based upon your make/model of the A/C compressor. VW will only sell the whole compressor as a replacement. A full vacuum and refill process will be needed.

As for the aluminum one made by/marketed as Graf, there are a few issues in my experience. First, the rubber gasket from the housing to the block is known to fail by tearing where the link in the gasket between the two passage connect. I think this is because the gasket does not precise fit in the channel for the seal machined into the housing. On the one that just put on an engine I just put in my '12 Tiguan, I cut that link out, effectively making two seals and relieving the tension in the seal. Next, the O ring seal supplied for the temp sensor is known to disintegrate, so I got a factory seal. Last, if your engine has a late water pump currently with the clip that holds in the temp sensor, the two mounting bolts to the block at the sensor will be too short for the aluminum pump housing, so you need to get the bolts for an early water pump. Honestly, as long as you don't have any oil leaks, the latest factory water pump is fine. I generally don't trust aftermarket water pumps, as I have had too many fail over the years (not on these engines, just in general). I used this Graf aluminum water pump as a test. The quality seems good, but time will tell.

replaced one twice

My previous body style tiguans never had an issue, now my 2018 has had a chip, then crack, got it replaced and got another chip weeks later. Had the previous style in rugged places like Colorado where I would get rocks flung up routinely, now it seems like the tiniest pebble will crack that thing.
