think I might unplug the radio completely to test if this makes a difference, would i need to unplug the radio from behind, or can i just remove a fuse ? and what about the 6 disc changer in the glovebox, ? unplug from the back or remove a fuse ? I have a horrible feeling my mate who suggested the steroe might be the problem to begin with, might be right after all, although the stereo was working right for months after the battery drain problem started and for months before the steering wheel controls started playing up. thanks for the tip |

You don't mention the battery. Have you checked it?

T4 is a dealer computer testing kit that can "talk to the car". A number of members here have such a kit.
There is another system call Toaf that I think you can put on your own lap top and if you have the right leads talk to the car. other members can guide you about Toaf. If you are going to leave the car for a few days, disconnect the battery but leave it in place. Have you tried removing individual fuses to equipment to see if that stops the battery going flat? good luck macafee2 |

I had a similar problem with my 2004 diesel, it would flatten the battery after 4 or 5 days of not being used. The battery was a brand new Bosch unit.
I put an ammeter in the battery positive line and disconnected the big flat fuse that supplies all the electrical bits in the car. Still the drain was there. I then unplugged all the wires going into the alternator including the heavy cable that is bolted in place - no current being drawn. Had a new alternator fitted and it’s been ok ever since. |

I can second that, I have one, not cheap but it certainly saves time, far quicker than dragging fuses in and out.

Mmm I think John (Rogerheinz57) was explaining a spurious fault thrown up by T4 as an example, and I can't see how a T4 check would help when investigating a parasitic drain fault.

I have a very similar problem. Checked all fuses and no apparent drain. I suspect that it may be the replacement webasto but had no way of checking until it goes to Chris for other work in the next month.
To get round the problem I bought one of these battery isolators. £7.95 https://www.ebay.co.uk/itm/123463209....c100667.m2042 If I am not using the car for a few days, I just disconnect it and happy days! I had to cut a small corner off the battery cover to fit. Please be aware that when you re-connect it the alarm sounds, so have your key fob handy. Don't be tempted to use the enclosed fuse as this defeats the purpose Good luck Regards Geoff |

If you disconnect the battery and then remove the 2 plugs from the Webasto that will remove it from the equation when you reconnect the battery.
