Please quantify roughly how many mk7s you've put a clutch in that "every one had a leaking rear main seal" or I'm calling BS. If your sample is one car and one defect, I'll buy it, but there is no way this is such a widespread defect or VW would have a line out the door. Incidentally another tuner told me the exact opposite. That the aftermarket ones have a bad habit of leaking and the latest OEM rev. aren't showing any issues. Coincidental that you sell the iAbed?
Yes we do indeed sell the iAbed, thank you for noticing.
The first MK7 clutch we replaced we didn't replace the rear main seal, however, this car was only a clutch replacement, flywheel remained in place so there was no way to validate it was or wasn't leaking. Since then, all clutch jobs have received a new flywheel whether it be SMF or new OE DMF. We have done at least 6 clutches on the MK7 so far.
You are certainly entitled to think what you think and whomever shop you use can certainly share their experience. Not all of them leak we certainly get that. Coincidentally the majority of the cars that have come through our shop have been.
If the shop you are dealing with are talking aftermarket, do you mind sharing what brand? There are many OE replacement seals that look just like the OEM seal that have a terrible track record. I have yet to see an iAbed seal leak on its own, we have a few improper installation reports though which isn't a failure of the seal itself. After experiencing the amount of failures first hand in the Gen1,2,3 TSI engines and what WE have seen so far on the MQB, I don't expect the track record to be much better. There are been quite a few reported early low mileage leaking rear mains on MK7's across the country not just our experience.
We have been recommending and installing this seal far before we started distributing them too.We don't like to sell or recommend something unless we know it works. With the overwhelming good luck we continued to have, we decided to use them exclusively after wasting our time installing OE rear main seals that continued to leak.
Mind you these aren't exactly pouring oil out but they are seeping and they certainly shouldn't be at this age/mileage. VW has used the same seal from 09-14 and the new "revised seal" isn't any better than the one it replaced. VW did have MK6 owners knocking on their doors with rear main failures, much of them stemmed from PCV failure. Unless you pull the transmission, you're not going to know its leaking until you clutch starts slipping horrible our you star seeing oil drip from the bell housing.
I'm not forcing people to buy anything, just sharing our experience to help the community make the best decision they can based off real life situation.
Cheers!
