Hi,
My 2003 53 406 2.0 hdi 110 engine management light and anti pollution message comes up and the doesnt pick speed up properly. Anyway took it to a garage this morning and the computer couldn't connect with the car he had a snap on computer, mechanic said their might be a problem with the wiring and said to bring it back tommorow morning...
Any ideas on what is going on?
Is it worth disconnecting the battery for a few hours but will I lose the key programme or CD code?
I am located in Birmingham if anyone is kind enough who can help me out.

Re: ECU not communicating
Not really but I do remember someone (Doggy?) saying they couldn't talk to their car because a fuse had blown

Re: ECU not communicating
Well for starters I would go through all the fuses to see if any are blown. I couldn't tell you which one it is I'm afraid

Re: ECU not communicating
Here is a picture of the fuse box just in case someone can circle or tell me which one it could be.

Re: ECU not communicating
The main fuse box is by your right knee as you're sitting in the car behind a panel.

Re: ECU not communicating
take a multimeter to all fuses, put it on the bleep setting, so when its over a good fuse it bleeps, and when its over a bad one it stays quiet, replace any silent fuses. Then there is also the earting point under the battery storage box worth a try. I think no2lurch had similar problems recently. Even a new battery is worth a try.

Re: ECU not communicating
Right gentlemens! It's not the same fuse on all cars - mine, (2002/52 fully multiplexed HDi), was F4, (10A), in the engine fusebox. mjb's car had the same problem, his is an early D9 V6 coupe and the fuse was F14, rating & location as above.

Is it under the steering column or is the fusebox in the engine bay the one I took pictures of as above?
Many thanks!

Re: ECU not communicating
Good idea! BTW I've read that removing the supplies from a Bosch EDC 15 ecu in the wrong order makes it think you're trying to hot-wire it, so it protects your vehicle by locking itself......

Re: ECU not communicating
You should be able to check them in situ with a meter on the exposed tags on top of the fuse.

Re: ECU not communicating
Hi all,
I checked the fuses and they looked fine but just for piece of mind I changed the 10 fuses.
Will pop down to the garage tommorow for the chap to take a look at it, disconnected the battery for now to see if it resets itself.
Any suggestions would be appreciated!
