This summer I took my HE coupe out to a friends bbq and I thought I'd top up the coolant before setting off. Opened the bonnet took the cap off filler her up. Took quite a bit of water which made me think... Got to my mates about 1.5 hours away and as I entered his drive he pointed out that the jag ...

Fitted DAC3749. Seems to work. Time good distance reading good. Lets see how long it stays functional!

I have a question: Can I replace my trip computer with one from a different model car with a different part number even though visually they look exactly the same? My computer is part no. DAC 2884 but I can't find one. I can easily get a DAC 3749 - but will it work?

Still the same. Leave it a day, doesn't work. Disconnect the fuse (new), reconnect, works. Absolute mystery. Would like to add that before doing the fuse disconnection I pulled and juggled and wiggled everything in sight. No joy. Then, just disconnected the fuse, reconnected and bingo. Worked.

So, had a bit of time today so fiddled about again. Disconnected the inline fuse housing, replaced fuse with new. Re-connected. Computer worked. Came back to it 30 mins later.... It didn't work. I'd left the computer sitting on the front of the ski slope as I thought more fiddling may be required. W...

Much appreciated RichardSEL, will follow instructions and report back. Watch this space...

Following day. Dead again.... I despair.

Would just like to add that I had an ignition amplifier failure and I had to crank the engine over many, many times in my attempts to cure it. I was sure the battery would loose power and fail to turn the V12 over but I was mightily impressed. It soldiered on until I cured the problem 2 days and man...

OK chaps (and chapesses) I prized the sucker out again as it was dead and wiggled with the wires. Nothing. No life. Then I jiggled about with the cable that has an in line fuse and bingo it came to life. So, I opened the fuse holder and scraped away at the surfaces that made contact with the fuse. S...

The problem is it works for a day or two then darkness. No computer. Flippin' annoying!

Just remembered I had a spare spark plug in the boot so I used it to check for a spark. As suspected - nothing - dead ignition electrics.

Thanks for help but this has now become the least of my problems! I was doing about 50mph on the A3 yesterday when the engine just cut out and the dashboard lights came on. No warning, no coughing or spluttering just instant engine cut out. I coasted to the side of the road and tried to re-start but...

Many thanks. I think one of the connectors is totally shot. Is it a vital part or am I ok to drive the car given that it probably doesn't function at all at the moment?

Hello, I've had my engine bay cleaned and this mystery part suffered a bit of damage. I'd like to replace it but I've no idea what it is or what it does! Any advices mutely appreciated. First photo wide so you can see where it is located: (1983 HE) IMG_4596.JPG Close up of part - the yellowy looking...

Haven't done that. Got no idea how to!
