Hi guys, I’m looking for some insight on my problem. It simply started as I pulled out from a car park, I accelerated maybe a little faster than usual nothing extreme, and all of a sudden I lost power. I pulled up for a minute contemplating my life 😂 then proceeded to try and pull away and managed to do so and get home about a mile away. Now the issue is the car is shuddering under acceleration. If I take it really slow through first gear I can avoid it but I mean really quite slow, then I to second again keeping it very low revs and slow paced but trying to accelerate at a normal pace it will shudder quite bad. This happened a few weeks ago and since it’s been parked up. I did notice a small oil leak on the floor under the gearbox and the gearbox casing is slightly wet. I just not sure if I should be expecting it to be a slipping clutch pack or just low hydraulic pressure due to fluid loss but as I mentioned it happened suddenly just pulling out of a car park. Anyway key information: (multitronic gearbox, CVT, driven 97,000 miles and no record of a gearbox service at all) hope someone has some helpful information

What engine and what fuel Declan?

It is the 2.0 diesel

My guess is the injectors or fuel pumps, but because their repair will be expensive it would be well to get confirmation from an electronic diagnosis before buying anything.

I appreciate the thought however, I had the injectors reconditioned around 600 miles ago along with a new turbo and the DPF deleted (and mapped out) what makes me feel like it’s the gearbox/clutch is when selecting gear I used to feel it pop into gear a little more pronounced that it feels now. I have done a little digging and found that if it was more of a clutch slip problem I should expect the revs to increase faster than the speed but the revs stay consistent it’s just the shudder when accelerating

That new information means all bets are off regarding diagnosis. Mapping has a bad reputation for causing engine problems.

You are right about the symptoms of a slipping clutch, (engine speed rising with no change in road speed,) so we can rule that out. I still believe it is an engine problem, though it needs somebody more knowledgeable than me for a diagnosis.

By the way your gearbox is not CVT.

As far as I have seen every other Audi page and a few auto transmission garages I have contacted state it is a CVT as it is the multitronic 7 speed. I can’t say for definite myself but just on what I’ve read and been told. I agree that mapping can cause problems and could definitely be a possibility though.

CVTs have what are effectively an infinite number of gears between minimum and maximum, hence the name Continuously Variable. It is misleading of Audi and others to falsely claim their boxes to be CVT when they have only a fixed number of gears, 7 in your case. Look up the gearboxes fitted to DAF vehicles many years ago for an example of a true CVT. They were dreadful things.

Ahhh this make more sense, a company claiming it is something when in actual fact it isn’t, sound about right, and even managed to get everyone on board calling it a CVT when it isn’t. Anyway, back on topic lol I have read the car with an OBD2 reader and have no faults, I’m to the understanding that it needs to be read on VCDS for more in-depth look to any gearbox faults
