Why do you say that? I've had a lot of cars fixed for clients that have brought an extended warranty



A lady that works for me had dealer insurance her gearbox on a VW DSG stuck in 3rd gear .The insurance company sent the car to some idiot workshop (they dont use dealer repair shops) that pulled the gearbox out and did massive damage not just removing the box but trying to pull down a box that neeed specialist tools .This took 12 weeks before the backyard work shop gave up. The car went to another back yard shop and sat in the yard for 4 week befoer been looked at and they said we cant fix other ppl stuff ups.She had the car towed to her place and its still sitting there 8 months later this is a car she spent $15000 on and the dealer said it would cost approx $8000 to repair but the Insurance company wiped there hands . GB> are you a dealer shop can you repair a DSG??

not sure why that happened like that as most of the cars I get fixed I send to my own workshops. In vic if the car is under 160k and under 10 years old I think will have statutory warranty for 3 months from the dealership it was brought from, where they decide to send it is kinda up to them, I have a few places that can fix a dsg's but it depends on what dsg is in it cause some have costed up to 10-12k to fix.
if the insurance company is giving them grief they should contact consumer affairs

Really the most likely part to go is the headgasket, which, as long as I don't cook the engine after that, is just a headgasket job. However if (when) the hg does go, you can be sure there would be some studs being used. That could be year away, so no need to burn money here imho


50% more torque with less cylinder pressure? Who's been telling you fibs?


I can't even remember where I found this gem, so I am an idiot for not verifying it (I WAS WRONG.. ish) ... I have done some resarch and found this, which shows that it's not QUITE as simple as it seems:

You can also read http://www-personal.umich.edu/~annastef ... _ACC09.pdf but it was too heavy for me and I didn't have the hours I'd need to make sense of it.


The explanation behind what I was saying - not entirely wrong, but again, more complicated.
A third issue is due to the chemistry of alcohol fuels for a given amount of air they produce more exhaust volume when they burn. Due to lower peak combustion temps (EGT might be 200 deg F lower on E85 for example) the peak cylinder pressure is lower but due to the high volume of exhaust gas products as the piston moves down the bore, pressure drops more slowly than it would on gasoline. This gives alcohol fuels an advantage in that the average cylinder pressure is a bit higher that it is on gasoline for a given peak cylinder pressure. This is what I was refering to earlier. Due to this higher average cylinder pressure if you leave the exhaust valve closed just a bit longer you can still get work out of the combustion gases a bit longer into the power stroke, but due to the higher exhaust gas volume you have more stuff to get out of the cylinder when you do open the exhaust valve so it make sense to use a slightly larger exhaust valve than you would be using with gasoline (or at least a higher exhaust port flow or valve lift ) to help the cylinder blow down in time so it does not interfer with both the intake cycle or make the the piston do work to push the exhaust gas out the port as it comes up the bore on the exhaust cycle.
