Unproductive wait

[Howard_silver]

Greetings everyone, I've been fortunate enough to possess my Evoque 2.2 Sd4 for the past two years; thus far, I've only had to repair the haldex, fuel pump, and passenger door lock. However, today it seems like my good fortune may have finally run out.

My issue is that in both forward and backward gears, when I come to a stop at lights, I have harsh idling, where the rev counter decreases and then rises again in a matter of seconds 🤔 There are no lights on the dashboard, and nothing appears on the scanner. I would really appreciate any assistance you can provide.


Much obliged.

A defective injector caused my first Evoque to have a rough idle until it warmed up. Perhaps comparable?

When the engine becomes hot, it occurs.

However, the issue seems to be with the gasoline supply.

About eight months ago, I had the low pressure fuel pump replaced. After doing some research on the old Internet, I was given three potential issues.

1. A Maf indicator
The throttle body should be cleaned.

3. The exhaust's oxygen sensor

Should I pay attention until a caution triangle appears, at which point I can decipher the code?

Would it be simple to clean or make changes to the above? I would want to do it myself if possible.

Much obliged.

Good day,

I had the same issue for several months. Even after two fuel filter changes, the problem persisted. I believe I finally got things fixed out after a good high-revving highway run. I'm not claiming that the Italian tune-up fixed yours, but it was the deciding factor for me.

Yes, I was considering that as well. I'll place it in S and paddle to fourth for half an hour to observe its behaviour; if it remains after that, who knows?
