Hi folks,
I am a new member here, but way back I had a 1999 A6 Quattro 2.8. Thanks for letting me in! I am in a bit of a jam and need to buy a car FAST.
The background here is that I will (very likely) be buying a B5.5 Passat Variant TDi (AVF or AWX) in Slovakia - soon, maybe in the next couple of days. I was going to go with a Rover 75 CDTi Tourer (BMW M47R engine), but they are getting rarer (good ones, anyway). So, plan B, and likely the more sensible plan, is the Passat. It will get 4-6 months use per year. It will get a remap or a tuning box (Synergy). Here is what I have gleaned from reading:
The AVF is only mated to the 6-speed. The 6-speed will probably fail catastrophically (or will it?). This combo has the 240mm clutch that will withstand some extra torque. Has anyone experience a failure of that gearbox? If so, what model year and at what mileage? Was the engine tuned? Is there any wisdom that says if the gearbox survives to 100,000 kms or 150,000 kms it likely isn't afflicted with the weak diff rivet problem? I'm trying to find out if it is at all safe to buy a Passat with that engine/gearbox combo (there are more of those for sale - perhaps for good reason?).
With that said, there IS a 2004 4-Motion for sale close by with the AVF & 6-speed. Is the 4-Motion a potential problem (by itself or in relation to the 6-speed gearbox)?
The AWX is only mated to the 5-speed. The 5-speed is more reliable and probably won't fail catastrophically. This combo has the 228mm clutch that WILL slip/fail with ANY additional torque from a tune or box. Should I stick with the AWX/5-speed combo and try to find a clutch that will survive a mild tune.
They both have a DMF that will fail with a tune or box (really?) - well, the 5-speed 228mm one, anyway. The 6-speed 240mm one, I don't know.
So, given this understanding, I think I had better go with the AWX 5-speed and find a clutch solution.
The power/torque would likely be maximum 120kw (160bhp)/385Nm (285 ft lbs). Must I replace the original DMF and can I get a 228mm clutch that won't slip and fail in 6 months or a year? The driving will be about 50/50 city/highway. The hardest loads will be 80-120 km/h overtaking. City driving will be fairly docile.
If I have misunderstood the info about engines, transmissions & clutches, please set me straight.
Thanks in advance,
Glenn
