Hi all, picked up an FSI last night (2003, full service history, 77k miles) and so chuffed about that.
It was fine on the test drive and the VCDS scan threw up a few codes which didn’t appear too serious but on getting the drive home underway, once it got warm, it started to stutter quite a lot and when idling, the rev counter was bouncing and shaking the car a bit. When accelerating, it seems to get a bit of a surge in acceleration when it hits around 3000rpm. Also, when driving at 65mph, I could feel it stuttering which would stop if I then put the accelerator down.
On getting it home I ran the diagnostic check again and have 8 codes now including throttle actuator (mechanical failure), cat system below threshold and knock control regulation limit exceeded on cylinders 1, 2,3 and 4. So the process of DIY elimination begins before I book it into B&F in Hounslow:
- will start with a full tank of shell v power once I’ve emptied what’s currently in the tank.
- will also check the Earth behind the headlight.
- will then change the ignition coils and spark plugs.
I have the Bosch part code for the ignition coils but can anybody recommend a specific spark plug? And assume it’s also 4 spark plugs?
If anybody has anything else I should add to the above list based on the fault codes, that would be much appreciated.
Thanks
