I just bought a used Audi TT on eBay, but the chip is fried (which the seller didn't mention ). It's one of those models with the chip glued to the chassis, is it possible to get a spare and how do I replace it? Or can a V1 chip be used without the cover?

Peer, obviously you cant do a warranty claim on it... but I do believe a V1 chip will fit. See if the guide connectors look the same (V1's and V2's are different), and simply hot glue it in place. Check for fit before even taking the cover off etc

The problem is that the original chip is not hot glued to the chassis; they used some kind of "super glue". I've had the same problem with another car, and I ended up breaking the chassis when trying to remove the remains of the chip, after using considerable force to break it loose from the chassis. I don’t want to ruin this car as they are hard to find digital.

I heard somewhere that the glue used will loosen up if you apply heat such as from a hair dryer for a few minutes and the chip will simply fall out of the chassis.

It's worth a shot as I agree too that this chassis would be hard to replace if you damaged it.

Also, a naked V1 should work and I might recommend a light amount of double stick to secure it for easy removal later.

Try to avoid super glue remover or debonder, it usually has acetone in it. Acetone will hurt the plastic.

Other than that, I agree with everyone else.

I tried to heat the glue with a hair dryer, but it didn’t just fall out, as I didn’t want to over heat the chassis. I managed to remove the chip, but ended up with a warped chassis (see pics), as I had to use some force. However I reheated the chassis and left it over night pressed between two pieces of wood, and it’s close to original. After removing some plastic from the chassis, the naked V1 chip fits tight and sits without any glue.

Hope this can be helpful for others with fried chips in old SCX cars.
After some test-laps I find the car running OK, but a bit noisy.

Dipping a bare chassis in boiling water alternated with bending it back into shape works great. Dip, bend, dip, bend, ect, ect.

Be careful with the boiling water. If you are under 18, ask your parents for assistance.
