Hello everyone,
I have 2009. Alfa 159, 1.9 JTDm 150hp. This is the short history of my problem:
- Bought the car with 100 000km in 2013.
- January 2014. 130 000km remapped 170hp & 390nm (the numbers may be wrong)
- January 2015. 150 000km factory clutch started to slip; bought the new one - Valeo (DMF, the whole clutch with with pressure bearing)
- January 2016. 160 000km clutch slipping again, bought the new one, Valeo again (without DMF and pressure bearing this time), and ordered a new map, something like 170hp and 360nm
- January 2017. 175 000km clutch start to slip again
Now I have 5 different maps, you can see in this photo fuel quantity for all of them. Only the green one 175hp/2 does not slip, all other slip in 5th and 6th gear, while the one 180hp slips in 4th gear as well.
Many tuners told me that stock Valeo clutch will hold 380nm, and that they newer saw something similar happening, but this clearly shows that everything beyond 335nm is just too much for this clutch. Maybe not when it is new, but after only 10 000km the problem arises.
Slipping is always from 2000rpm to 23000rpm, and then at 2500rpm it starts to grip and hold to the 4000rpm.
My driving style is very, very, VERY soft. I never put the pedal down until the engine is below 2300rpm, and I never do it hard, but slow and gradually.
98% of the time I am at low speeds, and around 2000rpm, but only sometime I speed up and use the whole torque and power. I think it is impossible that I ruined my clutch, except I can brake it by being to soft with it.
My car is in very good condition, my mechanic is also very professional and capable, at the same time it is hard to believe that 3 clutches are not good or installed correctly.

So my question is about Valeo stock clutch, is it really that bad so it can not bear anything more than 15nm, or I need to look somewhere else for the problem? The fact that 120hp and 150hp uses the same clutch, but 2.0 170hp different one says enough about how much torque this clutch can take.
Also, all problems started in January, with very cold weather, does that have something to do with my problem?
At the end, would you suggest some aftermarket clutch, and is there anything that will work 100% with remapped engine?
