| Restricted performance D4 |
|
Hi Guys and Girls
Can anyone give me some advice please. I brought a D4 about 3 months ago and after the first 4 weeks got the restricted performance orange warning light and went into limp mode with no throttle. Turned car off and drove another 200 miles with no issues.I booked it into a garage through warranty direct and it was diagnosed to be a faulty throttle body and inlet pipe. £1100 later. Driving the car again today and I got a Red warning light with restricted performance. Turned car off and restarted and it drove with no issues the rest of the journey.
This only seems to happen at 70mph or when booted from 65mph upwards. Before I go back to warranty direct and go through all the pain again has anyone had symptoms like this? Would it be worth cleaning the air flow sensors? I have used different fuel from different garages and the garage it went to completed a smoke test on it so no cracked manifold.
It’s driving me nuts 🥜

It won’t do any harm to clean the sensors providing you don’t poke anything into them, the airflow sensors will not cause this problem as they have a default setting if blocked, you can even disconnect them and the engine will still run, just won’t perform as it should.
Only answer is to have the fault codes read, best after they have been cleared. It can when others can't,
It will when others won't,
It goes where others don't.
