Just a quick update on the musty smell problem in the cabin. I was quoted £210 to get the car up in the air, take off some heat shields to access the drain pipe and clean it out which I thought was a bit steep so I have been searching the web for an alternative solution. I have managed to locate where the drain pipe joins to the bodywork of the car which can be accessed from the drivers side foot well on the right hand side of the centre console tunnel. My car is a UK model right hand drive 17 plate for your information. You need to take out 2 torx bolts one that holds the foot rest on and one that holds the plastic trim on, then you can pull back the carpet to access the pipe. Had trouble pulling off the pipe some comments say you have to twist it 90 degrees but eventually it came off. I then poured some water into the hole in the bodywork and looked underneath the car to see if it was draining, which it was so I am not sure that it was blocked in the first place. However I thought I might as well pour some very hot water with a bit of bleach in it to clear any muck that was left in the pipe. I don’t know if this has cured the smell I will have to wait a few weeks to see if it comes back. The only problem I have now is that someone on a website has said that there is another pipe the same on the other side of the centre console tunnel if so you can only access that by removing the whole of the tunnel which I am not prepared to do. If anyone knows if there is a second pipe on the other side that please let me know. Hope this helps someone. If the smell comes back it’s time for a new car.
