Q5 Turbo and Turbo Control Unit

Got a 2015 model with <18k miles.

New Turbo fitted 9 weeks ago. Same problem encountered last week but told it's the Turbo Control Unit now. Shocking and frightening when it happens. Both times on outside lane of busy motorways. 

Anyone else experience this?

Thanks in advance folks.

 

Welcome to the forum James :) 

sorry to hear your having issues! 

Thankfully it should all be covered under warranty! 

Iv not heard of any similar issues with the q5 but I'm sure other members will be able to help :)

cheers

IMO warranty in no way appeases me. Looking forward to other members replies.

Loss of Power. Vehicle goes into "limp mode". Pull over to safe area. Switch off engine. Restart. Continue journey <50mph. Call Audi Assist. Nightmare

That was exactly what I thought you were going to say...common fault when the turbo variable vanes gum up with carbon....just need cleaning with additives, and at very little cost.

Usually caused by smoking it around town and not revving the nuts off the engine, carbon builds up on the vanes and gums them in place.

Use the cleaner and give it an Italian Tune-up...that'll sort it out
