I got to field test my Cooper Discoverer AT3 4S tires in the snow this weekend. This is a solid A/T tire, and it's one of the quieter ones on pavement. Handling was awesome; ran them at 25 psi and plowed through small drifts ~12\" high with no issues.
I had the impression that those discs wouldn’t warp as easy as one piece discs but it looks as I was wrong. VW tried to machine my warped discs with them mounted on the car at one point but they failed so badly that they did not even want to show me the result. After that they messured the runout on new discs on the bench and found them OK. After the discs were mounted on the hubs they were messured again and that one of them had warped. That was the way they found the bad hub. I was quite surprised when I was told that VW did not have any tolerances for the runout on the hubs or the discs. I took for granted that they had quite strict tolerances both on the hubs and the discs. I don’t know if the eight piston caliper and the setup with opposed pistons makes the whole system more sensitive to warpage or not but that has been suggested. And to get this a bit more connected to the thread subject I can add that I have not found any alternative to VW original 365 mm floating discs at all. I was quite surprised to find them cheaper than the one piece 334 mm discs to my Passat W8 though.
Could be the hubs. Mine had an axial throw of 0,02-0,03 mm which I thought wouldn’t affect the discs. I filed a complainment to VW regarding warped discs and they blamed the calipers. Told me one of eight pistons was a bit sluggish. With new calipers and two sets of discs later they found what I had meassured before the complainment, a warped hub. The last pair have not warped after the typical 5000 km mark as before. So at least the floating 365 mm discs are very sensitive regarding straight hubs.
Thank you for this thread. I've installed 3 dashcams in our vehicles and quite familar with how to run them in the ceiling and along the door/windshield trim. Your picture of how to remove the radar/mirror cover gave me the confidence to gently pop that piece out slightly and run the wire through it. Now, I've got a great dashcam sitting behind the mirror and on the passenger side. Also, thank you for which fuse to tap into as that saved a lot of time. I also use the A119S and it's a great dashcam.
I'll be rocking my 225/50/17 Nokian Haka R2's on my Alltrack again this winter. Absolutely wonderful winter tire, I love everything about them, amazing on ice unstoppable in deep snow. My wife's 2015 Golf has 205/65/15 XIce XI2's which are great on ice, but maybe not quite as good as the R2's, I do find they are not nearly as good as the R2's in snow. Before you say it's an apples to oranges comparison, I used to have 205/60/16 Haka R's on my 2010 TDI Sportwagen so I know what these tires are like on a FWD car.
Pedal feel, modulation, and stopping is much improved over stock and pads are quiet so far. Modulation is much more progressive with less "initial bite" as it should be.
I recently did my brakes 2 weeks ago and very happy with how they came out. StopTech Centric Cryo rotors F & R, Hawk HPS 5.0 Street pads, 034 stainless brake lines.
I replaced mine two years ago, both rotors and pads front and rear, with VW parts purchased from VWpartsvortex. As I recall, they were not Brembo, probably ATE. I spent a total of $718 on the set, which seemed reasonable considering the rotor size and how long they last. So far, the new ones are performing very well. As an aside, a few years ago I replaced the rotors with Brembos on a Subaru and was disappointed: the front ones warped almost immediately. The bottom line, I'm afraid, is that it is no longer enough to rely on the brand, especially if sourced on the secondary market. At least with "VW" marked parts the reputation of the vehicle manufacturer is on the line, though even that may not be enough to ensure high quality.
Today I replaced the spark plugs with new ones PFR7S8EG VW genuine. With new plugs car runs better, but idle still wasn't good enough.
I have a 2008 1.4 TSI Tiguan bought from South African VW dealer, full dealer servicing too. Have had the coils replaced 7 times( kept burning out) spark plugs 4 times ( kept burning out too) and variouse other faults giving a total of 13 returns under warranty. The vehicle is now out of warranty with 139000 Km's (86000 miles) and the timing chain has failed bending valves etc. The vehicle took 3 weeks to repair and I had to pay R31000 ($2600 us) had a meeting with VWSA who say its normal wear and tear would not assist and didn't even apologies .
