[AudiQ5Canada]

Hi,
I own a 2012 Audi Q5 2.0. Up until now, I hadn't have any problems. About a month ago, I got a christmas tree in my dashboard: check engine light, abs light, tire pressure light, etc. I went to my local gagage (whom I have frequented for the past 20 years, but not an Audi dealer).

After scanning the codes, I was told that my ABS sensor needed to be changedm as well as a wheel bearing. I was told that the faulty sensor could have damaged the bearing (or maybe the opposite? I am not sure).

I left the mechanic but the check engine light was still on. I waited for a month but then I got a "break pads" warning in the dash, so I returned to the garage. They told me that my break pads were fine, but they replaced the front break sensor (!) and for the check engine, they told me it was the turbo that was being flagged. They said this was a 4000CAD job (the car is barely worth 10k after all these years). They lubricated the turbo's flap and told me to return is the check engine light shows up again.

Sure enough, 3 days later, it was back on. Not wanting to pay a 3rd time to "scan the error code", I did it myself using one of the cheap OBDII scanner on the market, and here is the result.

I don't know what I should do... Any suggestion or help would be much appreciated. I don't see any problem when I am driving the var though.

1- Should I just sell the car (who will buy a car with a check engine light turned on)?
2- Should I replace the turbo (4000CAD)
3- Should ignore the check engine light and ride it until it dies?

Any other suggestions?

Thanks

How many miles on your car?
I would clear the fault codes and drive the car. Without turbo boost it will be down on power but may drive for many more miles.

Hi,

Thank you for your reply. I have about 150 000 km (93k miles) on it.

Can I clear the "check engine" with the OBDII scanner or I need to do to the dealer?

Thanks

You ought to be able to, depending on which scanner you have? I used carista to clear mine.

I have a cheap scanner purchased from China.

Isn't there a risk to damage the motor if I continue driving while the turbo has some issues?

Thanks.

That seems unlikely, but would really depend on what is wrong with turbo. It could be something serious Watchdog: Shock at £7k repair bill for Audi Q5 turbo | Carbuyer or simply the waste gate not closing properly.

It is disappointing that your garage did not give you more details and a written report.

Is there a turbo specialist near you? Search for "Q5" (turborebuild.co.uk)

There's a extended warranty for your turbo booster and hopefully you've taken advantage of it.
