I have a 2015 Volkswagen GTI SE (2.0T) which is (a little over) due for an emissions test.
A few weeks ago I had some rear-end bumper damage repaired, and while in the shop they cleared the trouble codes - which apparently also resets all the emissions test 'readiness' checks in the ECU.
I have since driven the car a few 100 miles, and also tried to follow the following 'drive cycle' to get everything 'ready' (although it's a little difficult to do all this in traffic, so I'm not 100% sure that I've definitely completed it exactly as-written):
- Start engine & idle for 2-3 minutes
- Drive at 45-55mph for 7 minutes
- Accelerate to engine speed of 5000rpm, lift off until engine speed is around 1200rpm
- Accelerate to 60-65rpm & cruise for 5 minutes
- Drive at 50-70mpg for 30-40 minutes
But there's no change - the following are still marked as 'not ready':
- Fuel System
- Catalytic Converter
- Oxygen Sensor
I'm lucky that the current corona-virus situation gives me a bit of an extension to get the emissions test done, but I'm at my wits end trying to figure out what to do next.
Prior to taking the car in for the bumper repairs there weren't any codes which caused the 'check engine' light to come on, and I'm not seeing anything unexpected now either.
I'm using an OBDeleven scan tool if it makes any difference
