This is my first post so forgive me if I've placed it in the wrong forum. At 1800km my 2017 Q3 Quattro had its engine light come on and go off about 3 times. No performance issues or noises. It would stay on for a few hours and then disappear. I had to go by my dealership for something and decided to book the car for service. Turns out that the code it gave showed a fault in my camshaft position. After the dealer contacted Audi Canada, who apparently were aware of this problem because they quickly gave a plan, the action was to replace the camshaft entirely. This is what they replaced: Intake Camshaft, Roller Cam Followers/Rockers, Intake Cam Lifters, Camshaft Support Bracket, Camshaft Control Valve. They had my car for several days since the parts were'nt readily available here and the care is running fine. I dont believe there is a TSB out on this yet but I wanted everyone here to be aware of this potential issue.
This is my first Audi and my confidence has been a little shaken with the quality control aspect by the manufacturer. I hope they communicate this issue with all 2017 Q3 owners as it seems there was a parts supplier defect from the start (dealer service rep told me).

Understandably!! And thanks for the heads-up!

It is certainly a concern that a supplier's part may be defective in a number of cars, but it's good to know that Audi was quick to acknowledge the problem and follow through with a fix.

I personally can accept the occasional failure of a part, but Audi would lose me as a customer if they failed to be up front about the problem and correct it!

First, welcome to the forum and hope you come back to enjoy it and post your future great experiences and likes. No TSB yet, but will keep on the lookout too. I think this may be a rare occurrence and that is prolly why parts were not easily on hand. I have personally NOT heard of another case in my area (southeast US).

Replace Camshaft on 2017 Q3

So this is my first time ever writing in any forum! I just had to write because I just picked up my Q3 from service yesterday with the same problem. The car has 700 miles on it currently. I brought it in when it had 500 miles, 2 weeks old, engine light kept going on and off. It was annoying me because the car was brand new! So I was told it just had some loose wires and pins and gave it back. In a week the light went on for 5 straight days took it back and after 5 days in their hands, the car was repaired with a new camshaft etc. Exactly what Amblanz described. The service obviously had no idea or they would have looked for it and it would have been taken care of the first time I went in. The second time I went in was when they found the faults in the engine etc. So did they not do a thorough check the first time? hmmm....Anyway this is also my first Audi, not such a great experience thus far...

@bacino13 - Welcome to the forum - this issue is NOT a normal one and is yet to be subject to a TSB - at least in the US, not sure about Canada, but belive y'all have the CCTA engine too. Anyway, I'm glad they finally did get it figured out and that you found us. Please come back and visit more ...

Any chance you can send me the last 6-7 VIN digits of the affected cars so we can have an idea of the impact?
Thanks
sorry - don't have that info ...

Same story with my wife's 2017 Q3 front-wheel drive. Check engine light on at 2000 miles and currently in the dealers shop for a camshaft replacement. The dealer was not quite up on the codes they were getting and needed to consult with corporate, who authorized replacement. Can a Technical Service Bulletin be far behind, as I don't think we're an isolated case.

Definately NOT an isolated case - I said "batch" earlier not "bunch", but now I'm beginning to think "bunch" is a better quantification - although I have not seen a TSB yet ...

Post Cam Replacement - my wife says the car is a proper "driver" now. She didn't know how the car should have responded, but now she understands how things should be.

Alcon -

NO TSB on the Q3 yet, although one exists for the Q5 (CPMB engine), so not exactly the same -

Amblanz - same thing happened to me - after about 800 miles - they replaced all the parts you mentioned. Took almost 2 weeks to complete, I called Audi corporate and started a case that I did not trust this car and wanted a new one. And of course telling them after 800 miles this should have never happened! So after about 2 months and many phone calls they awarded me a new car with Audi buying my 1st one from me. So I have owned 2 Audi's Q3's brand new.

I found a few of these 2017 Buy-Back cars for sale on the used market, the Carfax lists these intake camshaft problems. A bad batch of hydroformed camshafts...probably one of the cam eccentrics breaks loose on the shaft, and spins freely. The eccentrics are attached to the hollow shaft by using high pressure water, inside the shaft, to expand the shaft to clamp inside the cast iron eccentrics, locking them in place.
