Strong exhaust smell coming from 2016 Golf TSI 1.8T

Recently purchased this car as a certified pre-owned. I've noticed that the exhaust smell from the car is strong even after having driven the car for more than an hour. It just has a "pollution" smell--like those American muscle cars from the 70's. I guess that's something I would expect when the car is first started, but it persists. Is this normal?

Maybe check if the catalytic converter is there (ie hasn't been removed) or if it isn't working properly.

But unless it has had an ECU tune to supress it I'd expect that you would be getting an error code, possibly a check engine light/msg.

There's also a fair amount of soot in the tail pipe. Not sure how common that is for this car.

I would get it checked out. I can't smell the exhaust on my 15 Golf even with the engine running in my garage (with the door open of course lol).

You said that it's a CPO car so you must have a warranty. Go back to the dealer.

Will definitely schedule to have the dealer's service department look at it. The sales guy told me that some soot in the tailpipe is normal, but I'm not sure.

Soot is normal.

Soot on the tailpipe is totally normal on these cars. I have seen some CPO's done on modified cars, I would have the dealer check the downpipe to see if its stock and the cat is working correctly.

It was a three year lease prior to becoming CPO--so I doubt anyone would modify it. The dealer claimed to have changed some downpipe seal when I complained about the exhaust entering the cabin (but that didn't fix the problem.)

Based on what I have seen in this forum leasing doesn’t stop people from modding.

I don't believe that the dealer would sell a CPO car without the stock DP and cat. Or a tune.

If the dealership did sell him a CPO that is modified he would have a pretty good case against them with VW for an exchange of some kind I'd imagine. That is assuming the modifications were still there during the certification process.

There's a long thread on Audizine about someone who purchased a tuned CPO car, it turned into a real headache for the customer.
